AfterWindow Energy Audits & Ratings in Palm Beach, FL
A window energy audit is a systematic inspection that measures how much heat, air, and moisture your windows are letting in or out - and assigns ratings that tell you exactly where your home is losing conditioned air and money. In Palm Beach, where summer cooling costs run high and humidity never really lets up, even a single underperforming window can add $30 to $60 per month to your electric bill. At Winslow Windows & Doors, Ed Winslow and our team have been running these audits since 2011, and we give you straight answers - not a sales pitch dressed up as an inspection.
If you’re already exploring your options, our Energy-Efficient Windows in Palm Beach page covers the full upgrade path. This page focuses specifically on the audit and rating process: what it measures, what it costs, and what happens after you have the numbers in hand. Call us at (561) 831-7863 - a live person picks up every call, any time of day.
When You Need Window Energy Audits & Ratings
Not every homeowner in Palm Beach knows their windows are underperforming. These are the clearest signs it’s time for a professional audit:
- Your electric bill keeps climbing, but your usage habits haven’t changed. Palm Beach homes often run air conditioning nine or ten months a year. If your FPL bill has crept up without explanation, window air infiltration is one of the first places to look.
- You feel a noticeable temperature difference near your windows. Standing next to a single-pane or older double-pane window on a July afternoon in Palm Beach can feel like standing next to a heat lamp. That radiant heat load is measurable, and an audit will quantify it.
- You have condensation forming on the inside of your glass. In the humidity we deal with along the Palm Beach coast, interior condensation usually signals a broken seal or inadequate low-E coating - both addressable once you know the exact rating of what you have.
- Your home is 15 or more years old and the windows are original. Windows installed before Florida Building Code tightened its energy requirements in 2010 rarely meet today’s SHGC (Solar Heat Gain Coefficient) or U-Factor standards. An audit gives you a baseline before you spend anything.
- You’re refinancing or preparing for a home sale in Palm Beach. Documented energy ratings can support an appraisal and give buyers concrete data, not just the word “efficient” on a listing sheet.
- A recent storm left you wondering about the seal integrity of your windows. Impact events - even minor ones - can compromise the gas fill between panes and drop a window’s insulating performance without any visible damage to the glass.
Our Window Energy Audits & Ratings Process
We run a structured, repeatable process so you get results you can act on, not a vague report full of hedging language. Here’s how it works, start to finish:
- Pre-audit walkthrough and utility review. Before we touch a single window, we ask to see your last 12 months of FPL bills and walk through your home to note the age, style, and visible condition of every window unit. This gives us context. A house in El Cid with original single-pane jalousie windows is a very different audit than a newer build in Palm Beach Country Estates with fogged double-panes.
- Frame and seal inspection. We check every frame - wood, aluminum, vinyl, or composite - for gaps, deteriorated caulking, failed glazing compounds, and visible seal failures. We pay particular attention to corners and the junction between the frame and the rough opening, where Palm Beach’s salt-air environment accelerates corrosion and sealant breakdown faster than you’d expect in an inland market.
- Glass rating verification. We cross-reference the visible NFRC (National Fenestration Rating Council) label or manufacturer’s label against current Florida Energy Code requirements. For windows without legible labels, we use our inspection tools to estimate U-Factor and Solar Heat Gain Coefficient based on glass thickness and visible coating characteristics. PGT and CGI units, which are common in Palm Beach due to their Florida-specific engineering, typically carry detailed NFRC documentation we can pull directly.
- Air infiltration assessment. Using a calibrated pressure test method and, where warranted, a thermal imaging tool, we identify points where conditioned air is escaping or outside air is entering. In Palm Beach, the east-facing windows of most homes take the hardest beating from prevailing ocean breezes, and that directional pressure is often the primary infiltration driver.
- Written rating summary and comparison to code. You receive a clear, written summary showing each window’s estimated or documented U-Factor, SHGC, and air infiltration rating, alongside the current Florida Building Code minimums for your climate zone (Palm Beach falls in IECC Climate Zone 1, the most demanding category for solar heat management). We note which windows pass, which fail, and by how much.
- Honest recommendation, no pressure. Ed’s name is on every job we do, which means our recommendation has to be something we’d stand behind in front of a neighbor. If your windows just need resealing and fresh weatherstripping, we tell you that. If a full replacement with a PGT or CGI impact-rated unit makes more financial sense over a five-year horizon, we show you the math.
What NFRC Ratings Actually Mean for Palm Beach Homeowners
The NFRC label is the standardized rating system used across the U.S., and understanding it saves you from being talked into the wrong Energy-Efficient Windows services product. Here’s what the key numbers mean in the context of Palm Beach’s climate:
- U-Factor (typically 0.20 to 1.20): Measures how fast a window conducts non-solar heat. Lower is better. Florida Energy Code requires a U-Factor of 0.65 or lower for residential windows in Climate Zone 1. Most modern double-pane units clear this comfortably; older single-pane aluminum frames frequently don’t.
- Solar Heat Gain Coefficient, or SHGC (0.00 to 1.00): This is the number that matters most in Palm Beach. It measures how much solar radiation passes through the glass and turns into heat inside your home. Florida Energy Code requires an SHGC of 0.25 or lower for most window orientations in Climate Zone 1. That’s a strict threshold. Many older windows have an SHGC of 0.60 or higher, which means more than half the solar energy hitting the glass ends up inside your home as heat.
- Visible Transmittance (VT): How much visible light comes through. Higher VT gives you a brighter interior but can come at the cost of a higher SHGC if the glass coating isn’t well-specified. This is a balance we help you think through based on your home’s orientation and your preferences for natural light.
- Air Leakage (AL): Expressed in cubic feet per minute per square foot of frame area. Florida code allows up to 0.30 for residential windows. Units with degraded seals often test well above this threshold.
When we complete your audit, every window gets mapped against these numbers. You’ll know exactly where you stand - not just generally, but room by room.
Window Energy Audits & Ratings Pricing in Palm Beach
Window energy audits in Palm Beach typically range from $150 to $400 for a standard residential inspection, depending on the size of the home and the number of window units. Here’s how pricing breaks down:
| Audit Scope | Typical Price Range |
|---|---|
| Small home or condo (up to 10 windows) | $150 – $220 |
| Mid-size home (11 to 20 windows) | $220 – $320 |
| Large home or estate (21+ windows) | $320 – $400+ |
| Audit with thermal imaging included | Add $75 – $120 |
| Written rating report with code comparison | Included in all tiers |
A few things affect where your job falls in those ranges. Homes along the Intracoastal in Palm Beach with floor-to-ceiling glass or custom geometric units take longer to assess than a standard grid of double-hungs. Homes where the original NFRC labels are missing or unreadable require additional verification time. And if you want thermal imaging as part of the assessment, that adds both equipment time and reporting work.
If you move forward with a window replacement after the audit, the audit fee is applied toward the installation cost. And if your repair is over $200, our standing $40 off any repair over $200 discount applies automatically. Seniors and veterans receive a permanent 10% discount on all services. There’s no trip charge for homes within our home county, and we never charge for a second opinion on a written estimate you’ve received elsewhere.

Why the Rating Numbers Matter Before You Buy Replacement Windows
Skipping the audit and buying windows based on a contractor’s recommendation alone is a bit like getting a prescription filled without a diagnosis. The Palm Beach market has no shortage of installers willing to put in whatever product they have in stock. The audit changes that dynamic: you walk into the replacement conversation with your own data.
We’re authorized installers for PGT and CGI, two ENERGY STAR Replacement Windows brands engineered specifically for Florida’s coastal climate, with SHGC ratings that meet or exceed the 0.25 threshold required in Climate Zone 1. When an audit shows that your east-facing windows are performing at an SHGC of 0.55 and a U-Factor of 0.90, we can show you exactly what a PGT WinGuard or CGI Series 4000 unit will change in those specific numbers. That’s a real before-and-after, not a marketing brochure claim.
We’ve done these audits in homes across Palm Beach County from Northwood to the South End, and one pattern shows up consistently: the windows that look fine from the street are often the worst performers on the rating sheet. Fogged or hazy glass is easy to spot. A broken Low-E & Argon Gas Glass coating or a deteriorated fill is invisible until you measure it.
The 36500-Day Done Right Promise
Every audit we complete and every window we install falls under our 36500-Day Done Right Promise. If something isn’t right, we come back and make it right. That’s not a marketing slogan - it’s the standard Ed Winslow has held Winslow Windows & Doors to since we opened in 2011. No national chain can hand you the owner’s word the way we can. A locally owned, owner-operated business has exactly one reputation to protect, and ours is built on 15 years of showing up and following through in Palm Beach.

FAQs – Window Energy Audits & Ratings in Palm Beach
How much does a window energy audit cost in Palm Beach?
A residential window energy audit in Palm Beach costs between $150 and $400, depending on the number of windows and whether thermal imaging is included. Small condos or homes with 10 or fewer windows typically fall in the $150 to $220 range. Larger estates with 21 or more units run $320 and up. If you move forward with a replacement after the audit, the audit fee is credited toward the installation. Call (561) 831-7863 for a free estimate specific to your home.
What SHGC rating do windows need to meet Florida Building Code in Palm Beach?
Florida Building Code requires an SHGC of 0.25 or lower for most residential windows in Climate Zone 1, which covers Palm Beach. This is one of the strictest solar heat gain requirements in the country, reflecting how much solar radiation homes here absorb year-round. Many windows installed before 2010 have an SHGC well above that threshold. Our audit identifies the exact rating of each unit and flags anything that falls outside current code minimums.
Can a window energy audit tell me whether I need repair or full replacement?
Yes, that’s one of the primary purposes of a structured audit. Some windows fail only at the seal level and can be resealed or have weatherstripping replaced for a fraction of the cost of a new unit. Others have Insulated Laminated Glass with fundamentally inadequate coatings that can’t be corrected without full replacement. The audit gives you that distinction in writing, with numbers attached, so you’re not guessing. We’ll always tell you when a repair is the smarter call.
Do I need a window energy audit before replacing windows in Palm Beach?
It’s not required by law, but it’s worth doing before any significant replacement project. Without baseline ratings, you’re comparing your old windows to marketing claims rather than to real performance data. The audit takes a few hours and pays for itself if it helps you prioritize which windows to replace first or confirms that a few units can be resealed rather than replaced. Think of it as getting the numbers before you make a decision that will be on your home for the next 20 years.
