AfterHow Much Does HVAC Cost in San Antonio?
Most San Antonio homeowners pay between $150 and $650 for a typical HVAC repair in 2026, while a full AC installation runs $3,500 to $7,500 depending on system size and efficiency. A seasonal tune-up sits at the low end, usually $80 to $200. At Brandt HVAC Co San Antonio, you get a written price before any work starts, so the number you agree to is the number you pay.
HVAC Cost Breakdown (2026)
| Service | Typical San Antonio Price Range | What’s Included |
|---|---|---|
| AC Repair | $150 – $650 | Diagnostics, parts, labor, written guarantee |
| Furnace Repair | $150 – $700 | Diagnostics, parts, labor, written guarantee |
| AC Installation | $3,500 – $7,500 | New system, removal of old unit, installation, startup testing |
| Tune-Up / Maintenance | $80 – $200 | Seasonal inspection, cleaning, safety check, efficiency adjustments |
Those ranges cover most single-family homes in San Antonio. A capacitor swap, one of the most common AC repairs in our climate, typically falls at the low end. A compressor replacement can push toward the top. Furnace repairs trend a bit higher because heat exchangers and blower motors cost more in parts. We list these numbers plainly because you shouldn’t have to guess what a repair might cost before you pick up the phone.
Every job with us starts with a written price. No estimate ranges on a napkin, no “we’ll see when we get in there.” Our technicians diagnose the problem, put the number in writing, and you approve it before any tool comes out.
What pushes a job toward the top of those ranges? Age of the equipment. Accessibility of the unit. Whether it’s a heat pump or a standard split system. A 20-year-old Goodman in a cramped attic closet takes longer to work on than a 5-year-old Trane on a ground pad. Parts availability matters too. Some older Rheem and York components ship from out of state, and that changes both the timeline and the cost. We’ll tell you all of this upfront.
What pulls the cost down? A well-maintained system. If you’ve had regular tune-ups, components fail less catastrophically. A unit that’s been cleaned and inspected annually usually needs a simple part swap instead of a multi-component overhaul. That’s the argument for the $80 to $200 seasonal visit, and we make it without apology: it’s cheaper than a compressor.
What Affects HVAC Pricing in San Antonio
- System age. San Antonio homes built during the 1990s and early 2000s housing boom often still run original equipment. A 25-year-old Lennox or Bryant unit costs more to repair because parts are harder to source and other components tend to fail during extraction.
- Climate load. We run our ACs eight to nine months a year. A condenser that’s been cycling daily since March has more accumulated wear than the same unit in a milder market. That’s not a sales line; it’s why capacitors and contactors fail more often here than anywhere else we work.
- Unit location. Attic installations, common in Alamo Heights and older Terrell Hills homes, add labor time. Crawl space and closet installs cost more than garage-mounted units. Techs work in 130-degree attics in July, and that access difficulty shows up in the price honestly.
- System type and brand. A Daikin mini-split repair prices differently than a Carrier central air system. Heat pumps cost more to service than furnace-only setups. The brand matters for parts: Trane and American Standard share components, which keeps those repairs on the lower end of the range. Exotic or discontinued models sit at the top.
- Efficiency rating. Higher SEER2 units use variable-speed motors and complicated control boards. More efficient systems save money monthly but cost more per repair. We’ll talk you through the math before any repair on a high-efficiency unit so you can decide with real numbers.
- Time of year. The first 100-degree week of June floods every HVAC shop in Bexar County with calls. Emergency repair during a heat wave isn’t priced differently by us, but you may wait longer for parts. Booking a tune-up in March or October is the smart way to avoid the rush entirely.
How to Save on HVAC in San Antonio
None of this is a secret, but most homeowners learn it the hard way after a July breakdown. Here’s what actually moves the needle:
- Book the tune-up. $80 to $200 once or twice a year catches loose connections, low refrigerant, and failing capacitors before they destroy a compressor. A maintenance call costs less than one emergency visit.
- Change your filters every 30 to 60 days. A clogged filter forces the blower to work harder, overheats the system, and shortens the equipment’s life. This is the single cheapest thing you can do, and most San Antonio dirt and pollen seasons make it monthly work.
- Don’t ignore the small noise. A clicking relay, a slow-starting compressor, a slight whistle from the furnace. These are early warnings. A $175 repair today beats a $650 repair in two weeks, and it always beats a full replacement.
- Ask for the written price, every time. If a company won’t put the number in writing before starting work, call someone else. We’ve done written pricing since day one, and we’ve been doing this since 2003 as part of the Threshold Group family of home-service companies.

What You Should Know Before Calling an HVAC Company in San Antonio
You’re letting a stranger into your home. That’s the reality of any home service call, and it matters. We don’t think it should feel like a gamble.
Brandt HVAC follows what we call the Threshold Verified standard. Every technician we send is background-checked and identity-verified before they ever knock on your door. Before your appointment, you get the technician’s name and photo sent to you. When they arrive, they show you a photo ID badge. If anyone arrives who you weren’t told to expect, that visit is on us, and we make it right.
The name Brandt comes from an old word for a firebrand. It fits the work of keeping a home warm on a January morning when the furnace won’t fire, and it fits how we approach the job: the people who show up are the people we said would show up.
Devin Marlowe leads our San Antonio team. The benchmark for every call is simple: you know the price before we start, you know who’s at your door, and you know what the guarantee covers in writing.
How HVAC Estimates Work at Brandt
- Call and describe the problem. A live person answers 24/7, including weekends and holidays. You’ll talk to a human, not a voicemail tree. Tell them what the system is doing or not doing.
- We schedule the visit and send a technician introduction. Before we arrive, you receive the name and photo of your technician. That person will say who they are at the door and show a badge.
- The technician diagnoses the issue. For repairs, that means finding the actual problem, not guessing. For installations, it means measuring your home, checking the ductwork, and sizing the system correctly. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.
- You get a written price. Before any work starts, you see the number on paper. Parts, labor, everything. You approve it or you don’t. No work without your sign-off.
- We do the work and hand you a written guarantee. Every repair includes a warranty spelled out in writing. If the repair fails within the guarantee period, our 365-Day Done Right Promise means a return visit at no charge. No argument, no fine print, just a repair that stays repaired.
- You decide if the work was done right. If it wasn’t, we come back and make it right. That’s the entire promise.
For an exact price on the problem you’re having, call (361) 470-8872. Estimates are free, and the price you’re quoted is the price you pay.
FAQs – HVAC Cost in San Antonio
How much does an AC repair cost in San Antonio?
Most AC repairs in San Antonio run $150 to $650. Simple fixes like a capacitor or contactor replacement sit at the bottom of that range; compressor work sits at the top. You’ll always get a written price before we start, so there’s no surprise at the end. Call (361) 470-8872 and describe what your system is doing, and we’ll give you a clearer picture before we even arrive.
How much does a furnace repair cost in San Antonio?
Furnace repairs in San Antonio typically run $150 to $700. Igniter replacements, flame sensor cleanings, and thermostat issues are at the low end. Blower motors and heat exchanger problems push toward the top. Every furnace repair with Brandt includes a written guarantee; if the repair fails within the covered period, the return visit is free under our 365-Day Done Right Promise. Call (361) 470-8872 for a quote on your specific issue.
How much does a new AC system cost in San Antonio?
A full AC installation in San Antonio runs $3,500 to $7,500 in 2026. The spread covers basic single-stage units at the low end and high-efficiency, variable-speed systems at the top. Ductwork modifications, new thermostats, and electrical upgrades add to the total if needed. We size every system to the home, not the other way around. Call (361) 470-8872 for a free installation estimate.
Is it cheaper to repair or replace an AC unit?
If the repair costs less than a third of the replacement price and the system is under 12 years old, repair usually makes sense. A $400 repair on a 7-year-old system is good money. A $600 repair on a 20-year-old unit that’s already failing twice a season is money toward a new system. We’ll give you the repair price and the replacement price side by side, and you decide with real numbers.
