AfterWindow Energy Audits & Ratings in Westgate, FL
A window energy audit in Westgate, FL is a systematic inspection that measures how much heat, air, and moisture your existing windows are letting through – and assigns each window a performance rating so you know exactly what’s costing you money on your FPL bill. Most Westgate homeowners who call us for an audit find at least one window that’s failing well below Florida’s current energy code, often without any visible cracks or obvious damage. If your AC runs longer than it should, or certain rooms never seem to cool down no matter what the thermostat says, an audit is the logical first step before spending anything on replacement.
We’ve been doing this kind of work across Westgate and the surrounding West Palm Beach communities since 2011, and Ed Winslow runs every job the same way he ran the first one: show up on time, give you straight numbers, and don’t recommend anything you don’t actually need. To see how audits fit into the full picture of Energy-Efficient Windows in Westgate, that page walks through every option we offer. Or call us directly at (561) 468-6136 – a live person picks up around the clock, no voicemail, no callback queue.
When You Need Window Energy Audits & Ratings
Westgate’s climate is specific: 90-degree summers, high humidity, afternoon thunderstorms from May through October, and the occasional cold snap in January that drops into the low 40s. That temperature differential – combined with constant solar exposure on west- and south-facing elevations – stresses window seals and frames in ways that cooler climates never see. Here’s when an audit makes sense:
- Your electric bill keeps climbing year over year. If your FPL bill has increased noticeably over the past two or three summers and you haven’t added appliances or square footage, window performance degradation is one of the most common culprits. An audit can isolate whether it’s the windows or something else.
- You feel a heat push near specific windows in the afternoon. In Westgate homes with western exposure – especially along neighborhoods bordering Haverhill Road – late-afternoon radiant heat through single-pane or older double-pane glass is a classic sign that the window’s Solar Heat Gain Coefficient (SHGC) is no longer doing its job.
- Condensation forms on the inside of the glass. Interior condensation on Florida windows usually means the insulated glass unit (IGU) seal has failed, argon fill has escaped, and the thermal barrier is gone. This is not a cleaning problem – it’s a performance problem that shows up clearly in an audit.
- You’re preparing to list the home or refinance. Energy ratings are increasingly showing up in home appraisals and buyer inspections in the Westgate market. Having a documented audit and current ratings on file gives you concrete data to support your asking price.
- You replaced your HVAC system but still have comfort complaints. A new air handler can’t compensate for windows that are transferring heat faster than the system can remove it. We regularly audit Westgate homes where the HVAC contractor correctly identified the windows as the remaining problem.
- Your windows are more than 15 years old and were never rated. Windows installed in Westgate before Florida’s 2017 energy code updates may carry no meaningful energy rating at all. An audit establishes a baseline and tells you which units are candidates for replacement versus which ones are still performing adequately.
Our Window Energy Audits & Ratings Process
We don’t walk around with a clipboard and eyeball your windows. Our audit process uses instrumented testing and cross-references manufacturer data against Florida Building Code requirements for Westgate’s climate zone (Zone 1 under ASHRAE/IECC classification). Here’s exactly what we do:
- Pre-visit documentation review. Before we arrive, we ask for whatever records you have: original window manufacturer specs, past energy bills if available, and any prior inspection reports. This saves time on-site and lets Ed or one of our technicians walk in knowing what vintage of product they’re likely to see. We confirm your appointment the day before – uniformed, background-checked technician, no surprises at the door.
- Visual and tactile inspection of every window unit. We check frame integrity, weatherstripping compression, hardware function, and glazing compound condition. We’re looking at the full assembly, not just the glass. Vinyl frames that have expanded and contracted through 10-plus Florida summers can pull away from rough openings in ways that no amount of good glass can compensate for.
- Thermal performance measurement. Using non-contact infrared thermometry, we map surface temperatures across each window’s glass and frame during active solar exposure or HVAC operation. This tells us the real-world delta-T (temperature difference) the window is creating inside your home. In Westgate homes with older single-pane aluminum-framed windows, we commonly measure frame surface temperatures of 110-120°F on a standard summer afternoon – a direct load on your cooling system.
- Air infiltration check at seals and perimeters. We use a smoke pencil or calibrated anemometer near frame edges and meeting rails to identify air movement. Florida Building Code 2023 sets an air infiltration limit of 0.3 cfm per square foot for operable windows. We test against that threshold and document any units that fail it.
- Rating assignment and comparison to current code. Each window gets a performance profile: estimated U-Factor, SHGC, Visible Light Transmittance (VLT), and air infiltration rating. We compare those numbers to ENERGY STAR’s Most Efficient criteria for Florida’s climate zone and to the Florida Product Approval ratings for equivalent current products – including the PGT and CGI lines we install. This gives you an apples-to-apples comparison between what you have and what a replacement would deliver.
- Written report with specific recommendations. You get a written summary – not a verbal rundown – that identifies which windows are still performing acceptably, which are borderline, and which are clear candidates for replacement. Where replacement makes sense, we give you upfront pricing. Where it doesn’t, we tell you that too. Ed’s name is on the business; recommending work you don’t need helps nobody.
Window Energy Audits & Ratings Pricing in Westgate
Window energy audit pricing in Westgate typically falls in the ranges below, depending on the scope of the inspection and the size of the home. These are honest market ranges – not teaser prices padded with add-ons later.
| Audit Scope | Typical Price Range |
|---|---|
| Single-window assessment (spot check, 1-3 units) | $75 – $125 |
| Partial-home audit (4-10 windows) | $150 – $250 |
| Whole-home audit (11+ windows, full written report) | $275 – $450 |
| Audit bundled with replacement estimate (no separate audit fee) | Included at no charge |
A few things affect where you land in those ranges. Homes with non-standard or custom window configurations take longer to assess than those with standard single-hung or casement units. If you have impact windows from PGT or ViewLux that are less than eight years old, the audit is often shorter because current Florida Product Approval data is readily available. Older aluminum-framed windows with no surviving documentation take more time to baseline.
No trip charge applies inside our home county. If you’ve already received a written estimate from another contractor and you want a second opinion, that second opinion is free – no strings, no pressure. And if your audit leads to a repair over $200, the standing $40 discount applies automatically. Senior and veteran households receive a permanent 10% discount on all services.
If you’re heading toward replacement rather than just an audit, the cost of the audit itself is folded into the project – you won’t pay for it twice. Call (561) 468-6136 and we’ll give you a clear number before anyone sets foot in your home.
What Your Window Energy Ratings Actually Mean
Florida has its own performance thresholds that differ from what you’ll see on national ENERGY STAR charts, and Westgate homeowners sometimes get confused by the numbers on a window’s NFRC label. Here’s a plain-English breakdown of the four ratings that matter most in this climate:
U-Factor
This measures how much heat flows through the window assembly overall. Lower is better. Florida’s 2023 energy code requires a U-Factor of 0.50 or less for most residential windows in our climate zone. For reference, a standard double-pane window with a low-e coating typically comes in around 0.30 to 0.35. Single-pane aluminum windows common in older Westgate homes often measure 1.0 or higher – roughly three times the maximum the code allows for new construction today.
Solar Heat Gain Coefficient (SHGC)
SHGC measures how much solar radiation passes through the glass and becomes heat inside your home. Florida code requires 0.25 or less for most applications – which is strict compared to northern states, for obvious reasons. This single number has the largest impact on your summer cooling load in Westgate. A window with an SHGC of 0.40 (common in older double-pane products) is letting in 60% more solar heat than a code-compliant window would.
Air Infiltration Rate
Measured in cubic feet per minute per square foot of window area. Florida code cap is 0.3 cfm/ft² for operable windows. Failed weatherstripping, warped frames, or degraded glazing compound can push this well above 1.0 cfm/ft² in older Westgate homes. Air infiltration carries humidity with it, which stresses your HVAC and can contribute to mold conditions in the wall assembly.
Visible Light Transmittance (VLT)
VLT doesn’t directly affect energy efficiency, but it affects livability. High-performance low-e coatings block solar heat without necessarily blocking light. Modern products from CGI and PGT can deliver an SHGC below 0.25 while maintaining a VLT above 0.40 – meaning you get a bright, natural interior without the heat load. Older tinted films that homeowners applied themselves often sacrifice VLT without meaningfully reducing SHGC.
Why Westgate’s Climate Makes Window Ratings Non-Negotiable
Westgate sits just west of West Palm Beach, in a pocket that gets consistent afternoon sun on western and southwestern elevations with limited natural shading from mature tree canopy – unlike some of the older neighborhoods closer to the Intracoastal. The result is one of the more demanding solar exposure profiles in Palm Beach County for residential windows.
We’ve audited homes in the Westgate neighborhood where west-facing bedrooms were running 4 to 6 degrees warmer than the rest of the house, entirely because the window SHGC was too high and the frames had delaminated from the rough opening. The occupants had been running a secondary window unit in that room for years rather than addressing the window. The replacement cost was recovered in reduced electric bills within four years.
Florida’s hurricane code also intersects with energy ratings in ways that matter locally. Impact-rated windows – the kind we install from PGT and CGI – carry Florida Product Approval numbers that document both their structural and thermal performance. A window can pass impact testing and still fail energy testing if it wasn’t glazed with qualified low-e coating. Our audits check both, because in Westgate you need both.
The Winslow Difference on Energy Audits
A lot of companies offer “free energy assessments” that are really just sales pitches with a flashlight. We do actual instrumented testing, produce a written report, and give you honest findings – including when your windows are fine and you don’t need anything. Ed Winslow has been doing this in Westgate and the surrounding communities since 2011, and the Done Right Promise applies to every recommendation we make: if we tell you a window is performing to spec, we stand behind that assessment. If we miss something, we come back and make it right.
Every technician who arrives at your door has passed a background check and arrives in uniform. You’ll know who’s coming before the truck pulls up. We answer the phone 24 hours a day, 7 days a week – a real person, not a recording. And upfront pricing means the number we quote is the number on the invoice. No line items that appear after the fact.
Our full range of home exterior services – windows, doors, and roofing – means we can often identify when a comfort or energy problem crosses over into the roof assembly or door system, not just the windows. That kind of whole-envelope perspective is harder to get from a window-only company.

FAQs – Window Energy Audits & Ratings in Westgate
How much does a window energy audit cost in Westgate, FL?
A whole-home window energy audit in Westgate typically costs between $275 and $450, depending on the number of windows and how much documentation exists for your current units. Spot checks on one to three windows run $75 to $125. If the audit is bundled with a replacement estimate, there’s no separate audit fee. Call (561) 468-6136 for a specific quote – estimates are free and there’s no trip charge inside our home county.
What’s the difference between a U-Factor and an SHGC rating?
U-Factor measures overall heat transfer through the window assembly – how much heat moves through regardless of sunlight. SHGC (Solar Heat Gain Coefficient) measures specifically how much solar radiation passes through the glass and becomes heat inside your home. In Westgate’s climate, SHGC is usually the more impactful number because solar gain dominates the summer cooling load. Florida code requires 0.50 or lower U-Factor and 0.25 or lower SHGC for most residential applications in our climate zone.
Can a window pass impact testing but still fail an energy audit?
Yes – and this is a common finding in Westgate homes. Impact ratings and energy ratings are tested separately and governed by different standards. A window can be fully Florida Product Approval-certified for wind and impact loads while carrying an SHGC that exceeds Florida’s energy code threshold. This is one reason we check both sets of ratings during every audit. Products from PGT and CGI are available with insulated laminated glass in configurations that meet both standards simultaneously, which is what we recommend for new installations in this area.
How do I know if I need an audit or just a replacement estimate?
Start with the audit if you’re not sure which windows are actually failing – a full replacement estimate without audit data can lead to replacing windows that are still performing adequately while leaving problem units in place. If you already know specific windows are the issue (visible seal failure, obvious air movement, broken hardware), a replacement estimate with a built-in assessment is more efficient. Either way, call (561) 468-6136 and we’ll ask a few quick questions to point you toward the right starting point. No obligation, no pressure.
