Security Bars for Windows with Air Conditioners: The Complete USA Installation Guide
Learn how to install security bars for windows with air conditioners safely. Step-by-step guide covering egress codes, DIY tips, and top products for US homes.
From our experience protecting thousands of homes across the USA, SWB analyzes the best strategies so you can sleep soundly — and that includes one of the most common challenges renters and homeowners face every summer: installing security bars for windows with air conditioners. Millions of Americans rely on window AC units to survive brutal heat seasons in cities like Houston, Atlanta, Chicago, and Phoenix. But that same open window slot creates a glaring vulnerability. According to the FBI Uniform Crime Report, roughly 60% of all residential burglaries occur through ground-floor windows — the exact same windows most people use for window AC units. The good news is that combining a window AC unit with steel security bars is absolutely achievable without sacrificing safety, ventilation, or fire egress compliance. This guide walks you through every step — from measuring your window opening to choosing between telescopic and fixed bar systems — so you stay cool, secure, and legally compliant all year long.

Why Window AC Units Create a Serious Security Vulnerability
When you slide a window open to fit an air conditioner, you are doing more than letting in cool air — you are creating one of the most common entry points for residential break-ins in the United States. According to the FBI's Crime Data Explorer, approximately 2.5 million burglaries occur in the US annually, and law enforcement agencies consistently identify unsecured or partially opened windows as the number one point of unauthorized entry. A window propped open around an AC unit leaves a gap — sometimes 6 to 10 inches on either side — that is more than enough space for an intruder to work with. In dense urban environments like New York City, Chicago's South Side, or parts of Los Angeles, ground-floor apartment dwellers with window AC units are statistically among the most targeted populations. What makes this worse is that many renters assume the AC unit itself acts as a physical barrier. It does not. A standard 5,000–8,000 BTU window AC weighs between 40 and 60 pounds and can be pushed inward or removed from the outside using basic leverage in under 60 seconds — a fact frequently documented in police reports across major US cities. The solution is installing purpose-built security bars for windows with air conditioners that frame the AC unit on both sides and, where needed, above it — creating a steel perimeter that no intruder can bypass without specialized tools and significant noise.
The AC Window Gap Problem Explained
A typical double-hung window in an American home measures between 28 and 36 inches wide. A standard window AC unit occupies 14 to 20 inches of that horizontal span, leaving anywhere from 8 to 22 inches of unprotected open space — sometimes on both sides of the unit, sometimes just one. Even when homeowners use foam filler kits or accordion-style side panels (included with most AC units), those plastic panels offer zero structural resistance. A determined intruder can punch through foam filler panels with a single kick. This is not a hypothetical scenario: New York City police department data from the past decade consistently cites window AC unit entry as a top three method for residential break-ins during summer months. The only structural solution is installing rigid steel bars that span the open sections of the window frame around the AC unit — a relatively simple DIY project that costs a fraction of a professional installation.
Who Is Most at Risk: Renters, Ground-Floor Apartments, and Families
According to the US Census Bureau's 2023 American Community Survey, there are approximately 44.1 million apartment renters in the United States. Of those, an estimated 28% live on the ground floor — roughly 12.3 million households. Ground-floor renters with window AC units represent the single highest-risk demographic for summer window break-ins. Parents are also a critical audience here: the New York City Department of Health mandates window guards under Local Law 57 for all apartments with children under 10 years old, and window guards must remain in place even when an AC unit occupies part of the window. Landlords in high-density cities like NYC, Philadelphia, and Chicago must navigate both tenant security requests and local building codes — which is why removable, adjustable steel bar systems from SWB have become a go-to solution for property managers.
Understanding Fire Egress Requirements When Installing Window Bars with an AC Unit
Before you purchase any window bar product, you must understand the fire safety and egress requirements that apply to your home under US building codes. Installing security bars incorrectly — especially in sleeping areas — can turn a security solution into a deadly trap during a fire. The International Building Code (IBC), the International Residential Code (IRC), and NFPA 101 (the Life Safety Code) all address window egress requirements with consistent language: every sleeping room must have at least one window or door that provides an emergency escape opening. The IRC Section R310 specifies that egress windows must have a minimum net clear opening of 5.7 square feet (5.0 sq ft for ground-floor windows), a minimum clear opening height of 24 inches, and a minimum clear opening width of 20 inches. When you add a window AC unit to that equation, the available clear opening shrinks dramatically — potentially below code minimums. This is why choosing the right type of security bar product matters as much as proper installation. Fixed, non-removable bars in a bedroom window that also contains an AC unit may violate IRC Section R310 and NFPA 101 — putting your family at risk and potentially exposing landlords to liability under state housing codes in California, Texas, New York, Florida, and Illinois.
IRC Section R310 and NFPA 101: What You Must Know
The IRC R310 egress window requirement is not optional — it is a life-safety code enforced in most US jurisdictions. For window bars installed in sleeping areas, this means that the bars must either be removable from the inside without tools (meeting the "quick-release" standard outlined in IBC Section 1031.2) or positioned in a way that preserves the full minimum egress opening alongside the AC unit. NFPA 101, Section 24.2.2 specifically states that security grilles, bars, or grates on windows or doors used as egress must be openable from the inside without keys, tools, or special knowledge. This code is why SWB engineered the Model A/EXIT — a patented egress-compliant bar system that satisfies IBC, NFPA 101, and OSHA standards simultaneously. For any homeowner or renter installing bars in a bedroom with an AC unit, the Model A/EXIT is the only fully code-compliant solution that maintains ventilation while meeting emergency escape requirements.
How the AC Unit Affects Your Egress Opening Calculation
Here is where the math matters. Suppose your bedroom window measures 36 inches wide by 24 inches tall — that gives you a raw opening of 864 square inches (6.0 sq ft), which technically meets IRC minimums. Now place a 15-inch-wide AC unit in the center of that window. Your remaining open space drops to 21 inches wide total — 10.5 inches on each side. At 24 inches tall, that gives you just 504 square inches (3.5 sq ft) of potential egress space, which is below the 5.7 sq ft minimum required by IRC R310. The practical solution is to mount the AC unit to one side of the window frame, preserving a single larger open section of at least 20 inches wide by 24 inches tall (the IRC minimums for width and height). Your security bars then cover the AC unit side and frame the open egress section with a quick-release mechanism on the egress panel. This is the installation approach SWB recommends and the configuration the Model A/EXIT is specifically designed to support.
Choosing the Right Security Bars for a Window with an AC Unit
Not every window bar on the market is designed to work alongside an air conditioning unit. When selecting security bars for this specific application, you need to evaluate four key factors: adjustability, egress compliance, installation method, and compatibility with your window's dimensions after the AC unit occupies part of the frame. At SWB, we manufacture three models designed to meet different security needs, and two of them are directly applicable to windows with AC units. The Model A Telescopic Window Bars ($90) offer fully adjustable steel bars that can be configured to fit the remaining open section of a window after the AC unit is positioned — fitting windows from 22 to 36 inches wide with no permanent drilling required. This is the ideal choice for renters who need a security solution they can remove at the end of a lease. The Model A/EXIT Egress Compliant Window Bars ($92) provide the same telescopic adjustability with the added benefit of a patented quick-release mechanism that satisfies IBC, NFPA 101, and OSHA requirements — making it the only responsible choice for bedroom windows. For ground-floor windows where the AC unit is in a non-sleeping area like a living room or kitchen, the Model B Wall-Mount Window Bars ($91) provide maximum structural security with heavy-gauge steel and a permanent powder-coated finish. Understanding which product fits your situation requires knowing your window dimensions, the size of your AC unit, whether the room is a sleeping area, and whether you rent or own your home.
Model A Telescopic Bars: Best for Renters and Adjustable Fit
The SWB Model A Telescopic Window Bars are the top choice for renters dealing with window AC units across American cities. The fully telescopic steel bar system adjusts to fit the open portion of the window frame — the section not occupied by the AC unit — without requiring drilling into the window frame or surrounding wall. Installation takes 15 to 20 minutes using the included hardware, and the bars can be removed cleanly when you move out, leaving no damage to the window frame or wall. For renters in Chicago, Philadelphia, or Detroit who face both extreme summers and significant burglary risk, the Model A allows them to keep the AC unit running all season while closing off the open window gap with solid steel bars. The matte black finish integrates cleanly with modern apartment interiors and does not interfere with the AC unit's side panels or drainage port.
Model A/EXIT: The Egress-Compliant Choice for Bedrooms
If the window with the AC unit is in a bedroom or any sleeping area, the SWB Model A/EXIT Egress Compliant Window Bars are the only product you should consider. The patented quick-release mechanism allows occupants to open the bars from the inside in seconds during an emergency — no keys, no tools, no special knowledge required, fully satisfying NFPA 101 Section 24.2.2 and IRC R310. The telescopic frame adjusts to the open section of the window alongside the AC unit, and the egress release bar operates independently of the AC unit installation. At $92, this is one of the most cost-effective ways to achieve full security and full code compliance in a single product. Homeowners in New York City navigating Local Law 57 compliance, as well as landlords in Houston and Atlanta managing multi-unit properties, will find the Model A/EXIT resolves both the security gap and the legal liability created by a window AC unit in a sleeping room.
Model B Wall-Mount Bars: Maximum Security for Non-Sleeping Areas
For ground-floor living rooms, kitchens, or commercial spaces where the window AC unit is not in a sleeping area and egress through that specific window is not required, the SWB Model B Wall-Mount Window Bars provide maximum structural security. The heavy-gauge steel construction and permanent wall-mount installation create a fixed steel perimeter around the window and AC unit that offers the highest level of forced-entry resistance available at this price point. The powder-coated black finish resists rust and weathering — important for exterior-facing windows in humid climates like those in Miami, New Orleans, and Houston. Property owners and landlords who want a permanent, low-maintenance security solution for commercial ground-floor windows will find the Model B the most robust option in the SWB lineup.
Step-by-Step Installation Guide: Security Bars Alongside a Window AC Unit
Installing security bars for windows with air conditioners is a straightforward DIY project that most American homeowners and renters can complete in under 30 minutes with basic household tools. The key is proper measurement, positioning the AC unit correctly within the window frame before installing the bars, and verifying egress compliance if the window is in a sleeping area. The following step-by-step process applies to SWB Model A and Model A/EXIT telescopic bars installed in a standard American double-hung or single-hung window with a window AC unit. For the Model B wall-mount installation, refer to the detailed instructions at the SWB installation guide. Always check your local building codes before installing any window security hardware — codes vary by city and state, and some municipalities (particularly New York City and Chicago) have specific requirements for both window guards and AC unit installation.
Step 1: Measure, Position Your AC Unit, and Assess the Remaining Opening
Begin by measuring the total width and height of your window opening. Record both dimensions in inches. Next, install your window AC unit according to the manufacturer's instructions — but position it to one side of the window frame rather than centered, if at all possible. Positioning the AC unit to one side maximizes the continuous open section of the window available for egress and bar installation. Measure the remaining open section: the width from the edge of the AC unit to the opposite window jamb, and the full height of the window opening. If this remaining section measures at least 20 inches wide and 24 inches tall, you meet the IRC R310 minimum egress dimensions. Record these measurements — they are what you will use to set your SWB telescopic bars. If the remaining open section is less than 20 inches wide, consider whether a smaller AC unit or a different window is more appropriate for your cooling needs and safety requirements.
Step 2: Configure and Install the SWB Telescopic Bar System
With your measurements in hand, extend the SWB Model A or Model A/EXIT telescopic bars to match the width of the remaining open window section — the portion not occupied by the AC unit. The telescopic mechanism adjusts from 22 to 36 inches, covering the full range of standard US window widths minus the AC unit footprint. Position the bar assembly horizontally across the open section of the window at the midpoint height of the opening. For the Model A, secure the end brackets against the window jamb according to the included instructions — most installations require no drilling when using the tension-mount method. For the Model A/EXIT, ensure the quick-release mechanism is oriented toward the interior of the room, accessible to all sleeping occupants, and test the release function before considering the installation complete. For the AC unit side of the window, use the included side panel bracket to secure the bar assembly against the side of the AC unit housing — this prevents lateral movement of the unit and eliminates the gap between the AC unit and the bar frame. Verify the entire assembly is level and firm before completing installation. Full detailed instructions are available at the SWB installation guide at https://securitywb.com/installation/.
Step 3: Test Security, Egress, and AC Unit Operation
Once the bars are installed, perform three critical checks before calling the project complete. First, test the security: attempt to apply lateral and inward pressure to the bar assembly — it should not flex, shift, or disengage under firm hand pressure. Second, test egress (for Model A/EXIT installations): activate the quick-release mechanism from inside the room and confirm the bars open fully within two to three seconds without tools. Practice this action with every member of the household, including children old enough to operate the release. Third, verify that the AC unit continues to operate normally — confirm the side panels create a tight seal, the drainage port is unobstructed, and the unit's airflow is not restricted by the bar assembly. Run the AC unit for 15 minutes and check for any unusual vibration against the bar frame — minor vibration dampening can be achieved with foam tape between the bar brackets and the AC unit housing.
Common Mistakes Homeowners Make When Combining Window Bars and AC Units
Even well-intentioned homeowners frequently make installation errors that compromise either security, fire egress compliance, or the performance of the AC unit itself. Understanding these common mistakes in advance will save you time, money, and potential legal liability — especially if you are a landlord managing multiple units in a high-density city. The following errors are among the most frequently documented by building inspectors and fire safety officers in major American cities, and each one has a straightforward fix using the right SWB product and installation approach. Broader home security context — including how window bars interact with other perimeter security measures like basement windows bars, sliding glass door sticks, sliding patio door deadbolts, and security grilles — is covered in the SWB comprehensive bars security guide.
Mistake 1: Installing Non-Egress Bars in a Bedroom Window
The most dangerous and most common mistake is installing fixed, non-quick-release window bars in a bedroom window that also contains an AC unit. This configuration can reduce the effective egress opening below IRC minimums and creates a fire safety hazard that has been directly linked to fatalities in residential fires — a fact documented in NFPA fire investigation reports going back decades. The NFPA reports that window bars and security grilles that cannot be opened from the inside have been contributing factors in fire deaths in residential properties across the United States. In a bedroom where the AC unit already reduces the available window opening, adding fixed bars without a quick-release mechanism creates a scenario where occupants cannot escape. The fix is simple: always use the SWB Model A/EXIT in any sleeping area, regardless of whether an AC unit is present. The $2 price difference between the Model A and Model A/EXIT is the most important $2 you will ever spend.
Mistake 2: Using the AC Unit Gap as the Only Egress Path
Some homeowners install security bars over the entire window — including the section occupied by the AC unit — with the assumption that they can push the AC unit out in an emergency. This is a dangerous misconception. A window AC unit installed with L-brackets (as required by most local building codes to prevent the unit from falling outward) cannot be quickly dislodged from inside during a fire emergency when seconds matter. The AC unit is not an egress path — it is an obstruction. The correct approach is to always preserve a dedicated egress section of the window that is protected by quick-release bars (Model A/EXIT) and completely independent of the AC unit. The AC unit side of the window can be secured with fixed bars or a standard Model A if egress through that section is not required by your layout.
Mistake 3: Incorrect Measurement Leading to Bar Instability
A telescopic bar system that is not properly sized to the window opening will not hold under forced entry. The most common measurement error is failing to account for the AC unit housing — measuring the full window width rather than the remaining open section after the AC unit is positioned. This results in bars that bridge across the AC unit housing rather than anchoring solidly into the window jamb, creating a structurally weak installation that can be defeated with minimal force. Always measure the open window section — jamb to AC unit edge — and set the telescopic bars to that specific measurement, ensuring the end brackets contact solid window frame material on both sides. Refer to the SWB product pages for Model A and Model A/EXIT for detailed measurement diagrams and size compatibility charts.
Security Bars and AC Units in Specific US Housing Types
The challenge of combining security bars with window air conditioners is not one-size-fits-all — it varies significantly depending on the type of housing, the window style, local building codes, and the specific crime risk profile of your neighborhood. From pre-war apartment buildings in New York City to ranch-style homes in Houston, from basement apartments in Chicago to ground-floor condos in Miami, each housing type presents unique installation considerations. Understanding how these variables affect your installation approach will help you select the right SWB product and configure it correctly for your specific situation. The following housing type breakdowns reflect the most common scenarios encountered by SWB customers across the United States.
Urban Apartment Buildings: NYC, Chicago, Philadelphia
In dense urban apartment buildings — particularly pre-war and mid-century construction in New York City, Chicago, and Philadelphia — windows are typically single or double-hung, 28 to 36 inches wide, and often face alleyways or low-traffic courtyards that provide cover for break-ins. These buildings were designed before central air conditioning, making window AC units nearly universal in older units. In New York City specifically, Local Law 57 requires window guards in apartments with children under 10, and the NYC Department of Buildings has specific guidance on window guard compatibility with AC units. The SWB Model A telescopic bar system — and the Model A/EXIT for bedrooms — is the ideal solution for NYC and Chicago renters because it installs without drilling into the window frame (protecting security deposits), adjusts to fit around any standard window AC unit, and can be removed and reinstalled when changing apartments.
Ground-Floor Homes and Basements in Suburban Areas
Ground-floor homes in suburban Atlanta, Detroit, Memphis, and similar cities with elevated residential burglary rates face a different set of considerations. Basement windows — often used for egress in finished basements that double as sleeping areas — are among the most vulnerable entry points in American homes. A basement window with an AC unit and no security bars is essentially an unlocked back door. For basement applications, the SWB Model A/EXIT provides both security and egress compliance for sleeping areas, while the Model B wall-mount is appropriate for non-sleeping basement utility windows. Suburban homeowners who own their property can also consider the Model B for permanent ground-floor window security on windows that do not serve as egress paths — living rooms, kitchens, and utility rooms where maximum forced-entry resistance is the priority.
Cost Comparison: DIY Security Bars vs. Professional Window Bar Installation with AC Unit Considerations
One of the most compelling reasons American homeowners and renters choose SWB telescopic window bars over professional installation is the dramatic cost difference — and this gap becomes even wider when you factor in the complexity of working around an existing window AC unit. Professional window bar installation in the United States typically costs between $600 and $1,800 per window, according to HomeAdvisor and Angi cost data for 2023. That price range reflects labor, materials, and the cost of custom-fabricating bars to fit around an AC unit — which often requires a welder or metal fabricator to create a custom frame that accommodates the AC unit housing. For a two-bedroom apartment in Chicago with three windows requiring security bars — including one bedroom window with an AC unit — a professional installation could easily run $1,500 to $3,500. By contrast, three SWB units (two Model A at $90 each and one Model A/EXIT at $92 for the bedroom) total $272 — a saving of $1,200 to $3,200 on the same coverage. Installation takes under an hour total with no tools beyond what most renters already own. Both Model A and Model A/EXIT are available through Amazon FBA with fast nationwide shipping, making them accessible to customers in all 50 states — including rural areas where professional security bar installers are difficult to find.
What Professional Installation Actually Costs Around an AC Unit
When you ask a professional window bar installer to work around a window AC unit, you are adding a custom fabrication requirement that significantly increases both cost and lead time. A standard rectangular security bar panel cannot simply be cut around an AC unit — the installer must either create a two-panel system (one section above the AC, one section beside it) or fabricate a custom single frame with a cutout for the AC housing. Either approach requires a site visit, custom measurements, fabrication time, and return installation visit — adding days or weeks to the timeline and hundreds of dollars to the invoice. Quotes from professional security bar installers in Los Angeles, Atlanta, and Chicago consistently show custom AC-accommodation pricing ranging from $250 to $500 per window above the standard installation rate. The SWB telescopic system eliminates this custom fabrication entirely — the adjustable steel bar spans the open section beside the AC unit precisely, with no custom work required.
Long-Term Value: Portability, Reusability, and Renter ROI
Beyond the initial cost savings, the SWB telescopic bar system offers a long-term value proposition that fixed professional installations cannot match. Because the bars are removable and adjustable, they move with you when you change apartments — a critical advantage for the roughly 35% of US renters who move annually, according to US Census data. A renter who spends $272 on three SWB units can reinstall those same bars in their next apartment the same day they move in — the investment pays for itself across every move. For landlords managing multiple units in cities like Houston, Philadelphia, or Atlanta, a stock of SWB bars represents a reusable security asset that can be redeployed between units and removed between tenants to facilitate inspections and window cleaning. This reusability makes the per-year cost of SWB bars far lower than any professional installation — often reaching a per-year cost under $20 per window over a four-year useful life.
Maintaining Your Window Security Bars and AC Unit Through Every Season
Installing security bars for windows with air conditioners is not a set-it-and-forget-it project — both the bars and the AC unit require periodic inspection and maintenance to ensure continued security performance and code compliance. This is especially important in regions with harsh winters (Chicago, Detroit, Minneapolis) or high humidity (Miami, New Orleans, Houston), where temperature cycling and moisture can affect steel hardware and AC unit seals over time. Developing a simple seasonal maintenance routine takes less than 15 minutes per window and ensures your security installation remains structurally sound, aesthetically clean, and fully functional year-round.
End-of-Season Checks: Fall Removal and Spring Reinstallation
In cold-weather climates, most homeowners remove their window AC units in the fall — which is the ideal time to inspect, clean, and store the SWB bar system as well. Before removing the bars, inspect all bracket contact points for rust, paint chipping, or hardware loosening. Wipe down the steel bar surfaces with a dry cloth and apply a light coat of silicone spray or paste wax to protect the matte black powder-coat finish through winter storage. When reinstalling in spring, measure the window section again before reinstalling the bars — windows can shift slightly in older housing due to seasonal wood expansion and contraction, and what fit perfectly last summer may need minor telescopic adjustment in spring. Test the quick-release mechanism on any Model A/EXIT units before the spring installation is finalized — release mechanisms should operate smoothly and without resistance.
Inspecting Bar Integrity and AC Unit Seals Together
Monthly, do a quick inspection of both the bar assembly and the AC unit foam seals. Press firmly on the bar frame at multiple points — any flex or movement indicates a bracket has loosened and requires retightening. Inspect the foam filler panels on both sides of the AC unit: cracked, compressed, or missing foam creates both a thermal inefficiency and a potential security gap. Replace damaged foam panels immediately — replacement foam seal kits are available at any major US hardware retailer (Home Depot, Lowe's, Ace Hardware) for under $10. Finally, verify that the bar frame has not shifted relative to the AC unit housing — vibration from the AC compressor can slowly work bar brackets loose over a season. Tighten all hardware and verify the bar-to-AC-unit contact point annually at minimum.
🏆 Conclusion
Installing security bars for windows with air conditioners is one of the most practical and cost-effective home security upgrades available to American renters and homeowners today. With over 2.5 million residential burglaries recorded annually by the FBI, and ground-floor windows accounting for 60% of all forced entries, the open gap created by a window AC unit is a security vulnerability that simply cannot be ignored — especially in high-risk urban areas like Chicago, New York City, Houston, and Atlanta. The good news is that solving this problem does not require a contractor, a permit, or a $1,500 professional installation. The SWB Model A Telescopic Window Bars, Model B Wall-Mount Bars, and the patented Model A/EXIT Egress Compliant Bars give every American homeowner, renter, and landlord a fully adjustable, code-compliant steel security solution that installs in under 30 minutes and ships directly through Amazon FBA to all 50 states. Whether you are protecting a bedroom window in a Chicago apartment or securing a ground-floor kitchen window in suburban Atlanta, Security Window Bars has the right product at the right price to keep your family safe all summer long — without ever sacrificing fire egress compliance, cooling comfort, or the security deposit you worked hard to protect.

Yes — and it is strongly recommended for ground-floor and basement windows. The correct approach is to position the AC unit to one side of the window frame, then install telescopic or fixed security bars across the remaining open section of the window. SWB Model A Telescopic Window Bars adjust from 22 to 36 inches and are specifically designed to fit the open section beside a window AC unit without interfering with the unit's operation. For bedroom windows, always use the Model A/EXIT with the quick-release mechanism to maintain fire egress compliance under IRC R310 and NFPA 101.
When installed correctly, SWB telescopic window bars do not affect AC unit performance. The bars are installed in the open window section beside the AC unit — not over the AC unit itself — so airflow, drainage, and power connections remain completely unobstructed. The only consideration is ensuring the bar brackets do not press against the AC unit's side panels in a way that blocks the side vents on certain models. If your AC unit has side vents (check the manufacturer's specifications), leave at least one inch of clearance between the bar bracket and the AC unit housing. Minor vibration between the AC compressor and the bar frame can be dampened with foam tape at contact points.
In most US cities, tenants have the legal right to install window security hardware, provided it does not permanently damage the window frame or building structure. SWB telescopic bars require no permanent drilling in many installations, making them renter-friendly by design. However, local laws vary: in New York City, window guards are legally required in apartments with children under 10 (Local Law 57), and in all jurisdictions, bedroom window bars must comply with IRC R310 and NFPA 101 egress requirements. Always notify your landlord before installation as a courtesy, and check your lease agreement for any specific clauses about window modifications. The SWB Model A and Model A/EXIT are designed to leave no damage to the window frame upon removal.
Measure the width of the window opening from jamb to jamb, then subtract the width of your AC unit housing to get the available open section. For example, a 34-inch window with a 16-inch AC unit leaves an 18-inch open section — which falls within the SWB Model A telescopic range of 22 to 36 inches when positioned to one side. If the remaining open section is less than 22 inches, consider repositioning the AC unit or selecting a smaller unit to maximize the available security bar footprint. Always verify that the remaining open section meets IRC R310 minimums for egress (at least 20 inches wide and 24 inches tall for bedroom windows). Contact SWB at https://securitywb.com/contact/ if you need help sizing bars for your specific window and AC unit configuration.
Yes — absolutely. Under IRC Section R310 and NFPA 101, every sleeping room must have at least one emergency egress window with a minimum net clear opening. When a window AC unit reduces the available clear opening, maintaining an egress section protected by quick-release bars becomes even more critical. Installing fixed, non-removable bars in a bedroom window that also contains an AC unit is a fire safety violation in most US jurisdictions and has been linked to fire fatalities documented in NFPA investigation reports. The SWB Model A/EXIT Egress Compliant Window Bars are specifically designed for this application — providing full steel security alongside a patented quick-release mechanism that satisfies IBC, NFPA 101, and OSHA standards without requiring tools or special knowledge to operate.
In most cases, yes — provided you use a tension-mount or no-drill installation method. The SWB Model A and Model A/EXIT telescopic bars are designed with renters specifically in mind: the tension-mount bracket system requires no drilling in many standard window frame configurations, leaves no holes or damage upon removal, and can be reinstalled in your next apartment. This makes them the ideal security solution for the 44.1 million apartment renters in the United States who want protection without sacrificing their security deposit. Always photograph the window before and after installation as documentation, and check your lease agreement for any window modification clauses. If drilling is required for your specific window type, consult your landlord in advance — many landlords in high-crime areas will approve the installation given the liability protection it provides.
The gap between the edge of the AC unit and the adjacent security bar bracket is a potential security weak point that must be addressed. SWB recommends using the included side panel bracket to press the bar assembly firmly against the AC unit housing, eliminating lateral movement of the unit and closing the gap between the AC side panel and the bar frame. Additionally, ensure the window AC unit is properly L-bracket secured (required by most local building codes) so it cannot be pushed inward. Foam weatherstripping tape (available at Home Depot or Lowe's for under $5) applied between the bar bracket and the AC unit housing creates a tight, vibration-dampened seal that eliminates any remaining gap. For maximum security on the AC unit side of the window, the SWB Model B Wall-Mount Bars can be installed over the AC unit section as a secondary fixed bar panel in non-egress, non-sleeping areas.
