How much HVAC work is happening in San Antonio?
The City of San Antonio issued about 922 HVAC permits a month over the 13 months from September 2025 to September 2026 — 11,982 in total. Activity rose about 35.7% between the first and second halves of the window — 4,638 permits to 6,295 — which clears the ±3.3% counting-noise threshold for a monthly total this size.
The busiest months in the window were June 2026 (1,195), July 2026 (1,194), August 2026 (1,130). Every permit in this count is identified by the city's own permit-type field, across 3 San Antonio permit types. This is a measure of activity and timing only — the city's permit record does not support a cost figure, and none is published here.

LIVEHow this count is put together
San Antonio issues a dedicated Mechanical Permit type, so these permits are identified by the city's own permit-type field — not by searching descriptions for the word “HVAC”. That matters: a type match either holds or it does not, while a text match quietly inherits whatever a clerk happened to type. Every permit type that rolled into this count is named below, with its share.
| City permit type | Permits | Share of records |
|---|---|---|
| Mechanical Permit | 10,872 | 90.7% |
| LSR Mechanical Permit | 983 | 8.2% |
| Mechanical Completion Permit | 127 | 1.1% |
| All permit records | 11,982 | 100.0% |
- Classification mechanism: the city's own permit-type field. No description-text matching is used for this category in San Antonio, so the count does not depend on how a clerk worded a job.
- Mapping version trades-v2. 3 permit types are mapped to this category; 3 issued at least one permit in this window.
- Trend threshold: ±3.3%. A permit count is a count of events, so its month-to-month wobble is Poisson — the standard deviation of a monthly count averaging 922 is about 30, or 3.3%. A half-over-half change smaller than that is not reported as a trend.
- Not published from this feed: any cost, price or typical-spend figure. San Antonio's DECLARED VALUATION field is 0.00% populated on every residential and trade permit type, and declared valuation is an applicant's fee-basis statement to the city rather than a paid invoice.
What else bears on a San Antonio HVAC decision
How much cooling a typical San Antonio year asks for
Cooling degree days measure how much cooling a period demanded, not how hot it felt and not what anything cost. This is the 30-year normal for one weather station near the city, summed across the year. It describes the climate a system here works in. It says nothing about any particular system — not its size, not its age, and not what it will need next.
Cooling demand in a typical year, San Antonio
3,474 cooling degree days, base 65°F
This is NOAA's 1991-2020 normal for SAN ANTONIO STINSON MUNI AP (USW00012970), 6 miles from our reference point for San Antonio, built on 19-20 years of record. It describes a typical year, not this one — the 30-year period it covers ended in 2020. The date on the badge above is newer than that because the same station also reports month by month, and its newest complete month is August 2026; that is what keeps this feed current, and it is not the figure shown here.
LIVEWhat a system costs to run depends on the rate as much as the equipment
This is the average price Texas households paid per kilowatt-hour in the most recent month the U.S. Energy Information Administration has published — a statewide figure, not a San Antonio one, and not your plan's rate. We publish the rate and stop there: turning it into a monthly bill or a payback period needs this home's actual consumption, which we do not have and will not assume.

Air quality is the one condition we measure that changes what a filter has to do
A system's filter is doing more work on a high-particulate day than a clear one. This is the current AirNow reading for the San Antonio area — an area measurement, not a reading at any address, and it describes today rather than the season.

FEED DOWNThe federal 25C credit for HVAC equipment expired on December 31, 2025
The Energy Efficient Home Improvement Credit under Internal Revenue Code section 25C — the credit homeowners claimed for qualifying heat pumps, air conditioners and furnaces — was ended by the One Big Beautiful Bill Act. The IRS states the test plainly: the credit “will not be allowed for any property placed in service after December 31, 2025.” Placed in service, not purchased — so equipment bought before July 4, 2025 but not placed in service until after the cutoff does not qualify. There is no grandfather provision. If a quote or an installer’s page still prices the credit in, that is a reason to ask, not a reason to hurry. One qualification the IRS attaches to this guidance itself: these FAQs are not published in the Internal Revenue Bulletin, so the IRS will not rely on them to resolve a case — though a taxpayer who relies on them reasonably and in good faith is protected from accuracy-related penalties.
What we looked for and did not publish
These readings would belong on this page. Each is missing a specific input, named here rather than left as a gap a reader has to notice.
- Equipment-age or pipe-era percentile — how your system compares to the local housing stock. Parcel-level year-built data. The Bexar Appraisal District records request has not returned, so no parcel data exists for San Antonio.
- Typical HVAC replacement cost in San Antonio. A cost source that is not permit valuation. Blocked, not merely unbuilt — see the measurement in docs/audits/round-6-permit-measurement.md.
San Antonio HVAC permit questions
How many HVAC permits does San Antonio issue?
About 922 permits a month on average across the 13 months from September 2025 to September 2026, 11,982 in total. These are mechanical permits issued by the City of San Antonio, counted from the city's own permit record.
When is HVAC work busiest in San Antonio?
The busiest months in the window were June 2026 (1,195), July 2026 (1,194), August 2026 (1,130). Mechanical permit activity in San Antonio concentrates in summer, which is when cooling systems are under the most load and failures surface.
Is HVAC activity in San Antonio going up?
Activity rose about 35.7% between the first and second halves of the window — 4,638 permits to 6,295 — which clears the ±3.3% counting-noise threshold for a monthly total this size. A change smaller than the counting noise on a monthly total of this size (±3.3%) would not be distinguishable from ordinary month-to-month variation, so it would not be reported as a trend.
What does a San Antonio HVAC permit cost?
We do not publish that, and this data cannot support it. San Antonio's DECLARED VALUATION field is 0.00% populated on every residential and trade permit type, and declared valuation is in any case an applicant's fee-basis statement to the city rather than a paid invoice. A cost figure needs a different source.
Do I need a permit to replace an HVAC system in San Antonio?
The city issues mechanical permits for this class of work, which is why the activity shows up in this record at all. Whether your specific job needs one is a question for the City of San Antonio's Development Services department, not for us — the permit record shows what was issued, not what the rule requires.
