Home Energy Audit Cost - Same-Day Service, Done Right the First Time

How Much Does Home Energy Audit Cost in Austin?

A home energy audit in Austin typically costs between $150 and $550, with most homeowners paying around $300 for a comprehensive assessment of a single-family home. That range covers everything from a basic walkthrough with an infrared camera to a full diagnostic audit with blower door testing and a detailed written report. Austin Energy has historically offered subsidized audits for its customers, which can bring the price down to $50 or less in some cases, though availability changes year to year.

Here’s the thing about that range: it’s wide because “energy audit” means different things to different companies. Some charge a flat fee. Some roll the audit cost into a future insulation job. Some offer a free visual inspection and call it an audit. At Woolsey Insulation Austin, we believe the price should be clear before anyone walks through your door. That’s the Kingswell Guarantee in action: a written price before any work starts, no surprise line items, no door-step math. If you want to know exactly what you’ll pay for an attic and spray foam insulation audit in Austin, call us at (361) 418-9997. A live person answers, day or night.

Before we get into the numbers, let’s be clear about what we do. Woolsey Insulation Austin installs and services attic insulation and spray foam insulation. We don’t do windows, we don’t do HVAC, we don’t do roofing. Our audits focus on the thermal envelope of your home, with special attention to the attic, where Austin homes lose the most conditioned air and gain the most heat. That focus means our pricing reflects exactly what we inspect and what we recommend, not a bait-and-switch to sell you a new AC unit.

Home Energy Audit Cost Breakdown (2026)

Here’s what a home energy audit costs in Austin in 2026, broken down by the type of audit and what’s actually included. These are real ranges we see in this market, not national averages that ignore Texas pricing.

Now, let’s talk about what those numbers mean in practice. The free to $75 visual inspection is exactly what it sounds like: someone walks through, looks, and tells you what they see. There’s no blower door test, no infrared camera, no duct leakage measurement. It’s a starting point. Several Austin insulation companies offer these free as a sales tool, and there’s nothing wrong with that, as long as you understand you’re getting a sales visit, not a diagnostic audit.

The $250 to $400 standard diagnostic audit is where you start getting real data. A blower door test depressurizes your house and measures exactly how much air leaks through gaps and cracks. An infrared camera shows you where insulation is missing or compressed. At Woolsey, we focus our audits on the attic because that’s where the biggest energy losses happen in Austin homes. Our technicians are background-checked and uniformed, and you’ll know exactly who’s walking into your home before they arrive.

The $400 to $550 comprehensive audit adds duct leakage testing and a combustion safety check. In Austin, where many homes run gas water heaters and furnaces in attics, that combustion safety check matters. A poorly vented gas appliance in a tight attic can backdraft carbon monoxide into your living space. It’s a real safety concern, not a scare tactic.

What drives the price up or down within these ranges? Home size is the biggest factor. A 900-square-foot bungalow in Travis Heights takes less time to test than a 4,000-square-foot house in Steiner Ranch. Older homes with multiple additions often have more complex attic spaces, which means more time with the infrared camera. And if you want the full written report with a prioritized action plan, that’s additional work beyond the testing itself.

What Affects Home Energy Audit Pricing in Austin

Austin’s market has specific factors that push energy audit pricing up or down. Here are the big ones, with the local context that matters:

• Home size and layout. A two-story house takes longer to audit than a single-story ranch. Multiple attics, knee walls, or a room over the garage add inspection time. More time means a higher price. Most auditors in Austin charge by the hour or by square footage brackets.
• Age of the home. Austin’s housing stock spans from 1920s bungalows in Hyde Park to brand-new builds in Mueller. Older homes often have settled insulation, original single-pane windows, and gaps around framing that newer homes don’t. A 1960s home in Allandale needs a more thorough audit than a 2020 home in East Austin, and the price often reflects that.
• Equipment used. A blower door and infrared camera cost real money, and a company that owns and maintains that equipment charges more than a company that does visual-only inspections. You’re paying for data, not opinions. We think the data is worth it, especially in a climate like Austin’s where summer cooling bills can hit $300 or $400 a month for an inefficient home.
• Whether the audit is subsidized. Austin Energy has run residential audit programs for years, and when funding is available, you can get a diagnostic audit for under $100. The catch is that the program specifics change, and the wait times can be long. If you call Woolsey Insulation Austin instead, you’ll get a live person on the phone immediately and an audit scheduled on your timeline, not a utility program’s.
• Attic accessibility. Some Austin attics are a nightmare to inspect: low pitch, deep blown-in insulation covering truss chords, or access hatches in awkward closet corners. If our technician spends extra time maneuvering safely through a tight attic, that time shows up in the price. We’ll tell you before we start, not after we’re done.
• What’s included in the written report. A one-page summary costs less than a full prioritized remediation plan with recommended R-values, air sealing locations, and phased project costs. At Woolsey, every audit includes a written report and a written quote for any insulation work we recommend. That’s part of the Kingswell Guarantee: no verbal-only pricing, no “trust me” numbers.

Home Energy Audit Cost by Neighborhood: What We See in Austin

Prices don’t vary wildly from neighborhood to neighborhood, but the homes do, and that affects the audit. Here’s what our technicians at Woolsey Insulation Austin encounter across the city:

• Hyde Park and North Loop (1920s-1940s homes). These older homes have settled batts and rolls in the attic, often with an R-value around R-19 or less. They also have plenty of air leaks around original framing. Audits here tend toward the $300 to $450 range because there’s more to document. Attic insulation is often the single highest-return upgrade in these homes.
• Allandale and Crestview (1950s-1970s). These neighborhoods have a lot of fiberglass batts that have flattened to half their original depth. Attic ventilation is often poor. A standard diagnostic audit runs $250 to $350, and the findings usually point to air sealing plus new blown-in insulation.
• Circle C and Steiner Ranch (1990s-2000s). These newer homes have better insulation from the start, but they often have gaps at the attic access, recessed lights leaking air, and HVAC ducts running through hot attics. Audits run $250 to $400, with duct leakage testing being especially relevant here.
• East Austin (mix of old and new). The housing stock is split between original bungalows and new infill builds. Bungalows belong in the same category as Hyde Park. New builds usually have decent insulation but may have air sealing failures where the attic meets the walls. $250 to $350 is the typical range.
• Georgetown and Round Rock (northern suburbs). These homes run newer on average, but they’re also bigger. Square footage drives audit time. $300 to $450 is common for a comprehensive audit on a 3,000-plus-square-foot home.

One more thing worth knowing: in Austin’s climate, the attic is almost always where the biggest energy losses hide. Our summers run 100 degrees or more for weeks at a time, and an attic can hit 140 degrees in August. If your attic insulation is under R-30, you’re paying to cool your attic every single summer day. Our audits measure your actual insulation depth and R-value, then explain in plain language what improvement would mean for your cooling bill. No scare tactics, just numbers.

Is a Home Energy Audit Worth the Cost?

Short answer: yes, in most Austin homes, if you act on the findings. An audit that costs $300 can identify air sealing and insulation work that cuts $40 to $80 off your monthly summer electric bill. That’s a payback period of under a year in many cases. If your attic insulation is old and thin, the savings compound every summer after that.

Here’s how to think about it. An audit doesn’t save you a dime by itself. It’s a diagnostic. The value comes from knowing exactly where your house is leaking conditioned air, and then fixing those leaks in the right order. Without an audit, you might pay someone to blow in additional attic insulation when the real problem is a leaky duct system in a hot attic. Or you might replace your HVAC system, only to find your house still can’t hold temperature because the attic isn’t air-sealed.

If you already know your attic insulation is old, thin, or damaged, and you’re planning to address it anyway, an insulation-focused attic audit from Woolsey Insulation Austin is the smartest first step. We charge a fair price for the audit, apply that cost toward your insulation project, and put the written quote in your hand before any work begins. Call (361) 418-9997 and we’ll walk through what the audit covers and what it costs, with zero pressure.

How Woolsey Insulation Austin Approaches Audits

We’re an attic insulation and spray foam insulation company. Our audits reflect that focus. We don’t perform whole-home energy audits that include window replacement recommendations or HVAC load calculations. We inspect the thermal boundary of your home, with the attic as ground zero, because that’s where we do our best work.

Every audit we perform follows the Kingswell Way. That means a written price before we start, a committed arrival window, a clean work site, and a written report when we’re done. If we identify insulation problems and you choose to move forward with us, we put the scope of work in writing with an exact price. Materials come from brands we trust: Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. The recommendation matches your home, not whatever we happen to have on the truck.

Wool was the first insulation. Woolsey keeps the idea in the name, and the Kingswell Guarantee keeps the promise behind it. If we do insulation work in your home and it fails within 365 days, we come back and fix it. Free. In writing. That’s the 365-Day Done Right Promise, and it’s included on every job.

How to Save on Home Energy Audit

You don’t have to pay full retail for a home energy audit in Austin. Here’s what we tell homeowners who want the data without overpaying for it:

• Check Austin Energy’s current program. The utility has offered subsidized audits for years. When funding is available, you can get a diagnostic audit for under $100. Check their website or call their conservation line. Availability changes, so don’t assume it’s always there.
• Bundle the audit with insulation work. At Woolsey Insulation Austin, we credit your audit cost toward any insulation project you hire us to do. If you suspect your attic insulation is due for replacement, the audit is effectively free once you move forward.
• Get a written quote before scheduling. A company that won’t give you a written price before the audit is a company that might add fees later. We provide written pricing on every audit, every time. It’s a core part of the Kingswell Guarantee.
• Don’t pay for testing you don’t need. If you live in a newer home and your only concern is attic insulation levels, a full blower door and duct leakage test might be overkill. An insulation-focused attic audit gives you the data you need for less money. Call (361) 418-9997 and we’ll help you figure out which audit actually fits your situation.
• Ask about the report before you book. Some companies charge $400 and hand you a one-page printout. Others give you a detailed plan with R-values, air leakage rates, and prioritized recommendations. The report is the product you’re buying. Ours is thorough, and it’s yours to keep whether you hire us for the fix or not.

What’s Included in a Woolsey Insulation Austin Home Energy Audit

Our audits focus on the attic and the thermal envelope, but we don’t just glance around and call it done. Here’s what you’ll get when you hire us for a home energy audit in Austin:

• Attic insulation inspection. We measure current insulation depth, identify the material type, calculate the effective R-value, and document areas where insulation has settled, shifted, or been disturbed. In many Austin homes, we find R-19 or less where R-38 is the current recommendation for our climate zone.
• Air leakage identification. Using infrared thermography, we locate the specific gaps and bypasses where conditioned air escapes: around recessed lights, plumbing penetrations, attic hatches, and the top plates of interior walls.
• Attic ventilation check. Poor ventilation shortens the life of insulation and raises your cooling bill. We check soffit and ridge vents, but we don’t install them; we’ll tell you what we see and whether it’s working.
• Written findings and a written quote. You get a written report describing what we found, in plain language. If attic insulation or spray foam work would help, you get a written quote with an exact price. No verbal estimates. No “we’ll work something out.”

Spray Foam Insulation: What an Audit Might Recommend

In some Austin attics, spray foam insulation is the right call. Spray foam, a two-part liquid that expands on contact and seals gaps airtight, does two jobs at once: it insulates and it air-seals. That’s a meaningful advantage in a hot climate like central Texas, where air leakage accounts for a big share of cooling loss.

Spray foam costs more than blown-in fiberglass. In Austin, open-cell spray foam runs roughly $1.75 to $2.75 per board foot installed, and closed-cell runs $2.50 to $4.00 per board foot. That’s before any rebates or credits. An audit helps you decide whether spray foam is worth the premium in your specific home. In some houses, blown-in fiberglass at the right depth is the better value. In others, especially homes with ductwork in the attic, spray foam on the roofline creates an unvented attic that keeps ducts cooler and cuts cooling costs significantly.

We install both, and we work with eight leading insulation brands so we can recommend the right material for the house. The decision comes down to your budget, your home’s construction, and your long-term plans. The audit gives you the data to make that call without guessing.

Why Pricing Transparency Matters for Home Energy Audits

This industry has a transparency problem. Some companies advertise a free audit and then treat it as a two-hour sales pitch. Others quote one price on the phone and add equipment fees, report fees, and travel fees after the work is done. We know because we hear these stories from Austin homeowners every single week.

The Kingswell Guarantee exists to solve that problem. It’s not a slogan. It’s a specific, written set of promises, and it applies to home energy audits and insulation work alike:

• A written price before any work starts. Every job, every time, no exceptions. We tell you what the audit costs before you book, and that’s what you pay.
• A committed arrival window. You know when we’re coming, and we show up when we say we will. Background-checked, uniformed technicians are the only people who enter your home.
• A clean job site. We treat your home like it’s our own. If we make access through your attic hatch, we leave it cleaner than we found it.
• A written guarantee on the work. For insulation installations, that means the 365-Day Done Right Promise. If something fails within 365 days, we come back and make it right at no charge.

No fine print. No door-step surprises. That’s the Woolsey way, and it’s been that way since Glenn Hartley joined the Kingswell family of independently owned and operated insulation companies. These are local operations, not a corporate chain, and that means the person answering your call lives and works in the Austin area.

What Does a Home Energy Audit Find in Austin Homes?

We’ve performed enough audits in the Austin market to know what we’re going to find before we even climb into the attic. Here’s what’s typical:

• R-values well below current recommendations. Many homes built before 1990 have attic insulation of R-19 or less. Current guidance for central Texas suggests R-38 to R-49 in the attic. That gap means real money leaking through your ceiling every summer.
• Gaps around attic access doors. The pull-down stair or hatch in a hallway closet is a giant hole in your ceiling, and it’s almost never air-sealed. It’s often the single biggest air leak in the house.
• Recessed lights leaking air. Older can lights are rarely air-tight, and they pump conditioned air into the attic all summer. We see this constantly in Austin homes from every era.
• Settled or disturbed insulation. Blown-in insulation settles over time, and any work in the attic, from cable installers to electricians, inevitably compresses or moves it. A home that had R-38 twenty years ago might be at R-22 today.
• Ductwork in the hot attic. Many Austin homes run HVAC ducts through unconditioned attics, where summer temperatures exceed 130 degrees. While we don’t repair ducts, our audit documents the conditions that make attic-level air sealing and insulation so important.

An audit turns these observations from hunches into measurements. Once you know your attic insulation is at R-22 instead of R-38, the decision to add blown-in insulation becomes a math problem, not a guessing game. That’s the entire point.

Frequently Asked Questions About Home Energy Audit Costs in Austin

How much is a home energy audit in Austin in 2026?

Most Austin homeowners pay between $150 and $550 for a home energy audit in 2026. The typical comprehensive audit with blower door testing and infrared scanning runs about $300. Austin Energy sometimes offers subsidized audits for $50 or less, but availability varies. At Woolsey Insulation Austin, insulation-focused attic audits start at no cost when combined with insulation work. Call (361) 418-9997 for an exact written quote before you book.

Does Austin Energy still offer free home energy audits?

Austin Energy has historically offered subsidized home energy audits for its electric customers, sometimes at $50 or less. Program availability changes with funding cycles, so current pricing isn’t guaranteed. If a subsidized audit isn’t available or the wait is too long, a private audit from an Austin insulation company typically runs $150 to $400. Call (361) 418-9997 to schedule an insulation-focused audit at a written price, with no waitlist.

Is a home energy audit worth the money?

A $300 home energy audit is usually worth it if your home is older than 15 years and you act on the findings. The audit identifies air leaks and insulation gaps that, once fixed, can cut $40 to $80 from your monthly summer electric bill in Austin. That’s a payback period of roughly a year. If your attic insulation is already known to be thin, skip the diagnostic and go straight to an insulation audit, which Woolsey credits toward the cost of the insulation work. Call (361) 418-9997 and we’ll help you decide what’s actually worth your money.

What’s the difference between a free audit and a paid audit?

A free “audit” from an insulation or HVAC company in Austin is typically a visual inspection, often as part of a sales visit. It costs $0 to $75 and includes no blower door testing or infrared scanning. A paid audit, at $250 to $550, includes diagnostic equipment that measures actual air leakage and thermal performance. The paid version gives you data you can act on. The free version gives you a sales pitch. We believe in written pricing for any audit we perform, and we credit the audit cost toward insulation work. Call (361) 418-9997 for a written quote.

Can you fix the problems found in an energy audit the same day?

In most cases, no. A proper energy audit produces a written report first, and the insulation or air sealing work follows. For attic insulation projects, we often schedule installation within a week of the audit. If you need an insulation-focused audit and already know you want the work done, we can sometimes combine the audit and installation into a single visit. Call (361) 418-9997 and we’ll tell you exactly what’s feasible, with a written price before we start.

What does an attic insulation audit cost in Austin?

An attic-specific insulation audit in Austin runs from $0 to $150, and Woolsey Insulation Austin credits that cost toward any insulation work you hire us to do. That’s lower than a whole-home energy audit because we focus on the attic and thermal envelope, not windows, doors, or HVAC equipment. If you want to know whether your insulation is doing its job before spending money on a fix, the attic audit is the most cost-effective way to find out. Call (361) 418-9997 and we’ll schedule it at a written price.
