Austin HVAC Permits: The Wave Starts in March

Austin filed 8,671 permits to replace a complete central heat and air system, which is 48.4% of every mechanical permit in the city. Those filings peak in July and start climbing in March, roughly four months before the heat that most people assume drives them. The A/C replacement market is not an emergency market. It is a planned one, and it is readable in advance.

TL;DR

• 8,671 full-system A/C replacement permits, 48.4% of Austin's mechanical file.
• July is the peak: 736 filings in 2026, 523 in 2025.
• The ramp starts in March, not June. February to March 2026 nearly doubled.
• Austin's biggest A/C replacement filer is a multifamily specialist, not a consumer brand.

How many A/C replacements does Austin permit?

Our City of Austin file holds 92,627 permits running to August 31, 2026, split across four types: electrical 27,330, plumbing 24,934, building 22,443 and mechanical 17,920.

Inside that mechanical file, 8,671 records carry a single description string: replacement of a complete existing central heat and air system, with or without duct work. It is a dropdown value in Austin's application system rather than free text, which is what makes it countable. Contractors sometimes append their own note ("LIKE FOR LIKE: 3 ton horizontal gas system"), but the prefix stays constant.

Around it sit the partial-system scopes: 133 mini-split replacements, 130 condenser-only, 62 furnace-only, and 164 other replacement descriptions. Together that is 9,160 permits, or 51.1% of Austin's mechanical file. More than half of the city's mechanical permitting is replacing equipment that already exists.

When does Austin's replacement season actually start?

March. This is the finding that matters most, and it runs against how the trade usually talks about Texas cooling demand.

Month	2025	2026
January	247	236
February	245	212
March	336	423
April	513	402
May	500	549
June	514	587
July	523	736
August	490	480
September	475
October	377
November	260
December	302

February 2026 recorded 212 full-system replacement permits. March recorded 423. The market nearly doubled in one month, in early spring, before Austin sees anything resembling summer.

By April the year is already running at double its winter floor, and it stays there through July. The peak-to-trough swing is about three and a half times, from 212 in February 2026 to 736 in July.

August, meanwhile, drops. 480 filings in August 2026 against 736 in July, and 490 in August 2025 against 523 in July. The hottest stretch of the Austin year is not the busiest permitting stretch, because a changeout gets permitted when it is planned, not when the unit dies.

If you are a mechanical contractor whose marketing spend ramps with the temperature, you are arriving after the filings.

Is 2026 busier than 2025?

Yes, and the growth is concentrated in exactly the months that matter. Comparing January through August, Austin filed 3,625 full-system replacement permits in 2026 against 3,368 in 2025, up 7.6%.

Narrow it to the March through July window and the gap widens: 2,697 filings in 2026 against 2,386 in 2025, up 13.0%. July alone went from 523 to 736, a 40.7% increase.

One caveat worth stating. Our Austin coverage becomes dense around mid-2024, so 2025 is the first full baseline year we hold and this is a two-season comparison. It is enough to describe a direction and not enough to call a trend.

Who files the most A/C replacements in Austin?

Texas Multifamily Solution, LLC, with 948 full-system replacement permits since January 2025. That is more than any consumer-facing brand in the city.

Contractor	Replacement permits since Jan 2025
Texas Multifamily Solution, LLC	948
Stan's Heating, Air, Plumbing, & Electrical	900
Radiant Plumbing and Air Conditioning	859
McCullough Heating & Air	729
American Residential Services (ARS)	479
ABC Home and Commercial Services	300
SERVICE WIZARD LLC	294
Alamo Austin Air Conditioning & Heating Inc	241
Cool Country Services LLC	215
Strand Brothers Service Experts	206

Those four leaders account for 3,436 of the 8,407 replacement permits filed since January 2025, about 40.9%. Austin's permit market overall is famously fragmented, with no contractor holding much of anything. A/C changeouts are the exception.

The multifamily story is the part worth acting on. Apartment operators replace condensers unit by unit across a property, so a single complex generates a run of permits rather than one. Compare the top filer against the three biggest residential brands by quarter and both follow the same seasonal shape, but the mix has shifted: in the second quarter of 2025 the multifamily specialist filed 194 against their 500, and across July and August 2026 it filed 211 against their 351.

For an HVAC contractor benchmarking against that leaderboard, the first job is deciding which market you are actually in. For a dumpster and junk removal operator, 8,671 changeouts is 8,671 old air handlers and condensers that left the building.

Why is the mechanical file the cleanest contractor list we hold?

Because of who is allowed to pull the permit. Austin requires a mechanical permit before a mechanical system is installed, altered, repaired or replaced, and only an air conditioning and refrigeration contractor licensed by the State of Texas and registered with the City may apply for one.

Texas licenses that contractor through the Department of Licensing and Regulation under the ACR program. A Class A licence covers equipment of any size. A Class B licence is capped at 25 tons of cooling and 1.5 million BTU per hour of heating, which is the practical dividing line between residential and larger commercial work.

That licensing gate shows up directly in the data. Austin mechanical permits carry a contractor name on 99.78% of records and a contractor phone number on 95.66%, the highest identity coverage of any permit type in any state we hold. It is worth remembering that Texas has no state general contractor licence at all, and Austin substitutes a one-time registration and a contractor PIN. The licensed identities in Austin are the trades, and the permit record reflects that.

The same reason our Austin electrical code coverage leans on the trade licence rather than a builder registration applies here.

What can the Austin mechanical file not tell you?

Three things, and none of them are recoverable.

There is no owner. The owner_full_name field is 0.00% populated across all 92,627 Texas records. A permit is a signal about the property owner, not the contractor, and Austin is the one file in the product where that owner is invisible. Use it as a competitive, recruiting and partnering file, not an owner-outreach list.

There is no job value. Project value appears on 13 of the 17,920 mechanical permits. Any Austin market-sizing in dollars would be invented, so we do not publish one.

And phone coverage is high, not universal. Fox Service Company filed 176 replacement permits since January 2025 with no phone number on any of them. Treat 95.66% as very good rather than complete.

One more limit: this is the City of Austin. Travis County's unincorporated areas run a separate permitting regime that is not in our file.

How permits.llc fits in

The value of a countable dropdown string is that it turns a vague market into a schedule. Austin's replacement wave has a February floor and a July ceiling, it moves in the first week of March, and it names the contractor on essentially every record.

To run these cuts yourself, download the Austin permit file and filter the mechanical records on the replacement description. The Texas permit type breakdown shows how the four types divide, and Travis County coverage shows the geography we actually hold.

If you would rather watch the March ramp than reconstruct it after the fact, put the mechanical file on a standing permit alert.
