Window Energy Audits & Ratings in Fort Lauderdale, FL

A window energy audit in Fort Lauderdale is a structured inspection that measures how much conditioned air your windows are letting escape, how much solar heat they’re letting in, and whether their performance ratings match what South Florida’s climate actually demands. Most homes we visit in Fort Lauderdale are losing between 25% and 40% of their cooling energy through windows that were never rated for this heat load - or that have degraded seals, single-pane glass, or frames that weren’t built for the coastal humidity here. The audit tells you exactly where the losses are, what a replacement window’s energy rating should be, and whether what you have now makes the grade.

If your electric bill keeps climbing even after you’ve had the AC serviced, or if you feel radiant heat near windows even with the blinds closed, a professional energy audit is the right first step before spending money on anything else. At Winslow Windows & Doors, Ed Winslow has been walking through Fort Lauderdale homes and doing this kind of honest diagnostic work since 2011 - and the finding is almost always the same: the windows are costing homeowners far more than anyone told them when the house was built or bought.

This page is part of our broader work with Energy-Efficient Windows in Fort Lauderdale. If you want to talk through what you’re seeing in your home right now, call us at (904) 747-8989. A real person will pick up.

When You Need Window Energy Audits & Ratings

Not every homeowner recognizes that their windows are the problem. Here are the signs we see most often in Fort Lauderdale that point directly to windows failing on energy performance:

• Electric bills that spike every June through September. Fort Lauderdale’s summer heat index regularly pushes past 105 degrees with high humidity. If your cooling costs jump sharply in early summer and don’t recover even when the AC is running constantly, window solar heat gain is almost always a contributing factor - especially in south- and west-facing rooms.
• Radiant heat near glass, even with window treatments closed. Single-pane glass and low-quality double-pane units with degraded Low-E coatings act like a radiator. If you can feel warmth standing 18 inches from a closed window, the glass is not performing.
• Condensation between panes on double-pane windows. When you see fogging or moisture between the panes of what should be an insulated unit, the seal has failed. That window has lost its insulating gas fill and is now performing at roughly single-pane levels. In Fort Lauderdale’s humidity, this happens faster than most homeowners expect.
• You’re about to replace windows and want real performance data first. Before spending $600 to $1,200 or more per window on a replacement, an energy audit tells you which windows are actually failing and which might be saved with weatherstripping or resealing. That’s money-in-pocket information.
• Your home was built before 2002 and has never had windows replaced. Older Fort Lauderdale homes - particularly in neighborhoods like Riverside Park, Tarpon River, and parts of Victoria Park - often still have original single-pane aluminum frames. These have no Low-E coating, no insulating gas, and no meaningful Solar Heat Gain Coefficient (SHGC) protection.
• You’re applying for a Florida homeowner’s insurance discount or an energy efficiency rebate. Some programs require documentation of window performance ratings. An audit gives you the rating data in a format utilities and insurers recognize.

Our Window Energy Audits & Ratings Process

We don’t hand you a pamphlet and call it a diagnosis. Here’s how we actually do a window energy audit in Fort Lauderdale:

1. Pre-visit intake and home profile. Before Ed or one of our uniformed, background-checked technicians arrives, we ask you about your home’s age, the direction it faces, your current utility costs, and any specific rooms or windows you’re already concerned about. That context shapes what we look for. Fort Lauderdale homes vary a lot by neighborhood - a 1960s CBS home in Lauderdale Isles has very different window challenges than a 2005 townhouse in Flagler Village.
2. Visual and physical inspection of every window unit. We examine frame condition, glass type (single, double, or triple pane), visible seal integrity, weatherstripping condition, and the presence or absence of Low-E coatings. We check for obvious air infiltration, frame warping from salt-air corrosion (extremely common within a mile of the Intracoastal), and any signs of water intrusion at the frame-to-wall junction.
3. Rating verification against Florida Building Code and ENERGY STAR thresholds. Florida’s climate zone (Zone 1 in Fort Lauderdale) has specific ENERGY STAR requirements: a maximum U-Factor of 0.40 and a maximum Solar Heat Gain Coefficient of 0.25. We check whether your existing windows carry ratings that meet those thresholds, and whether the installed condition still achieves them (a window that met code in 2001 may not by current standards, and a window with a failed seal no longer performs to its original rating regardless of what the sticker says).
4. Room-by-room heat gain and loss analysis. We document which elevations and rooms are the worst performers. South- and west-facing windows in Fort Lauderdale take the hardest solar beating - a west-facing window in a home in the Rio Vista or Seven Isles area can account for a disproportionate share of a home’s entire cooling load in July and August. Knowing this lets us prioritize recommendations rather than suggesting a whole-house replacement when two or three windows are driving 80% of the problem.
5. Written findings and product rating recommendations. You get a written summary of what we found, the current estimated performance of each window area, and - if replacements are warranted - what SHGC, U-Factor, and impact rating specifications to look for. If we recommend brands we’re authorized to install, like CGI or ES Windows, we’ll tell you exactly why those products fit the findings, not because they’re on a shelf we need to move.
6. Upfront replacement estimate if replacements make sense. If the audit identifies windows that should be replaced, we provide a firm, itemized replacement estimate the same day. Upfront pricing - no surprises on the invoice. If the audit shows your windows are actually performing adequately and the problem is elsewhere, we’ll tell you that too. Ed’s name is on the business, and telling you the truth when the truth saves you money is how we’ve stayed in Fort Lauderdale for over 15 years.

Window Energy Audits & Ratings Pricing in Fort Lauderdale

Window energy audits in Fort Lauderdale typically range in cost depending on the scope of the home and what’s included in the findings report. Here’s an honest look at what affects that cost and what you can expect:

A few things that affect where your audit falls in that range:

• Number of windows and stories. A single-story bungalow in Sailboat Bend with eight windows is a faster job than a three-story waterfront home in Harbor Beach with 24 window openings, several of them impact-rated sliders.
• Complexity of the window types. Homes with custom geometric windows, fixed picture windows above doors, or clerestory units above second-floor stair landings take more time to assess than standard single-hung or casement windows.
• Whether you need a formal written report for insurance or rebate purposes. A documented rating report formatted for a utility rebate application or a homeowner’s insurance premium reduction takes more time to prepare than a verbal walk-through summary.
• Salt-air corrosion inspection add-on. For Fort Lauderdale homes within a half mile of the ocean or the Intracoastal, we often recommend a more detailed frame corrosion inspection alongside the energy audit. Aluminum frames corrode from the inside out in coastal environments, and the energy impact of a corroding frame seal is significant.

If you’re a senior or veteran, our permanent 10% discount applies. And if the audit leads to a repair over $200, the $40 repair credit comes off that invoice automatically. We don’t time-limit those offers.

FAQs - Window Energy Audits & Ratings

What is a window energy rating, and what numbers should Fort Lauderdale homeowners look for?

A window energy rating is a set of standardized performance metrics that tell you how much heat a window lets in and how well it prevents conditioned air from escaping. The two numbers that matter most for Fort Lauderdale are the Solar Heat Gain Coefficient (SHGC) and the U-Factor. For Florida’s climate zone, ENERGY STAR Replacement Windows require an SHGC of 0.25 or less and a U-Factor of 0.40 or less - a lower SHGC means less solar heat enters the home, which is critical in a city where the sun is intense for eight or nine months of the year. If your windows don’t carry those ratings, or if the seals have failed and the ratings no longer apply, you’re paying for it every month on your electric bill. Call (904) 747-8989 and we’ll check your current windows against those benchmarks at no cost to the estimate conversation.

How much can energy-efficient windows actually reduce my Fort Lauderdale electric bill?

Replacing single-pane aluminum windows with properly rated double-pane, Low-E & Argon Gas Glass impact windows in a Fort Lauderdale home typically reduces cooling energy use by 15% to 30%, depending on how many windows face south or west and how poorly the originals were performing. For a home spending $250 to $350 per month on cooling in July and August, that’s a real monthly reduction. The audit tells you your specific situation rather than giving you a generic estimate. Homes in neighborhoods like Edgewood or Lauderdale Manors that were built in the 1960s with aluminum jalousie or single-pane windows tend to see the largest gains. Call (904) 747-8989 for an honest look at your home’s numbers.

Can you do a window energy audit the same day I call?

In most cases, yes - we can schedule a window energy audit in Fort Lauderdale within one to two business days, and same-day availability is sometimes possible depending on current workload. Someone answers when you call (904) 747-8989, 24 hours a day, seven days a week, so you’re not waiting until Monday morning to get on the schedule. We know Fort Lauderdale homeowners dealing with a hot room or a spiking electric bill don’t want to wait two weeks for a callback from a national chain that won’t send anyone from the area anyway.

Do I really need an audit before replacing my windows, or can I just pick new ones?

Skipping the audit means you might replace windows that were actually performing fine while missing the two or three that are causing 80% of your energy loss. We’ve seen Fort Lauderdale homeowners spend thousands replacing north-facing windows that were fine, while the real culprit was a pair of west-facing living room windows with blown seals. The audit tells you which windows to replace, what Energy-Efficient Windows services and ratings to specify, and what you can reasonably expect in savings - so the replacement budget goes where it actually does something. If the audit shows all your windows need to go, we’ll tell you that plainly, give you a firm quote, and explain why each window is on the list. Ed Winslow has been making those calls honestly in Fort Lauderdale since 2011, and the 36500-Day Done Right Promise means we’re accountable to that assessment long after the job is done. Call (904) 747-8989 to get started.

Why Fort Lauderdale Homeowners Call Winslow First

There’s no shortage of window companies in Fort Lauderdale. What’s in shorter supply are companies where the owner’s name is literally on the door, where a live person picks up at any hour, and where the promise behind the work - our 36500-Day Done Right Promise - isn’t written in fine print designed to disappear after the check clears.

Ed Winslow started this company in 2011 as a locally owned operation, and it’s still that. Every technician who arrives at your door is background-checked and in uniform. You know who’s coming before the truck pulls up. The pricing you get before the job starts is the pricing on the invoice. And when we tell you a window is performing or failing, we’re telling you what the data shows, not what makes the biggest sale.

We’re authorized installers for CGI, CWS, ES Windows, ECO Window Systems, and several other premium brands. When an audit points to replacement windows, we can spec and install Insulated Laminated Glass products built for Fort Lauderdale’s coastal conditions, impact requirements, and heat exposure. That’s a shorter list than our full brand lineup, but every brand on it is one we’ll stand behind.

For Fort Lauderdale homeowners who want to understand what their windows are actually doing – and what they should be doing, call (904) 747-8989. The estimate is free. The conversation is honest. And if there’s a problem we can fix, we’ll fix it right - or we’ll come back until we do.
