AfterHow Much Does HVAC Cost in San Antonio?
Most San Antonio homeowners can expect to pay between $150 and $650 for an HVAC repair, $80 to $200 for a seasonal tune-up, and $3,500 to $7,500 for a full AC installation in 2026. These numbers reflect the current San Antonio market, where summer cooling demand shapes both pricing and scheduling. A simple capacitor replacement lands on the low end of that repair range, while a compressor failure pushes toward the top.
What you’ll actually pay depends on the specific problem, your equipment’s age and brand, and whether the failure happens during a July heat wave or a mild January afternoon. Below, we break down every major cost category so you can plan with real numbers, not vague estimates.
HVAC Cost Breakdown (2026)
Here’s what San Antonio homeowners are paying for common HVAC services right now, based on the work we perform across Alamo Heights, Stone Oak, Helotes, Leon Valley, and the surrounding neighborhoods.
| Service | Typical Cost Range | What’s Included |
|---|---|---|
| AC Repair | $150 – $650 | Diagnosis, parts, labor. Simple fixes like capacitors or contactors run $150 – $300; refrigerant leak repairs or fan motor replacements run $350 – $650. |
| Furnace Repair | $150 – $700 | Diagnosis, parts, labor. Ignitor or flame sensor replacements on the low end; heat exchanger or blower motor work on the high end. |
| AC Installation | $3,500 – $7,500 | Equipment, removal of the old system, installation, refrigerant, and a full system startup check. |
| Tune-Up / Maintenance | $80 – $200 | Coil cleaning, refrigerant check, electrical inspection, filter replacement, and airflow measurement. Higher end includes both heating and cooling in one visit. |
These are the numbers we quote in San Antonio today. They hold across most equipment brands we service, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The biggest cost driver is almost always the part that failed and whether it’s still under manufacturer warranty. A compressor under warranty might cost you labor only, around $400 to $600. A compressor out of warranty can push a repair past $1,500, which is when replacement often becomes the smarter financial choice.
If you want a written price before any work begins, call (254) 271-2545. We provide that on every single visit. No exceptions, no pressure.
What Affects HVAC Pricing in San Antonio
San Antonio’s climate and housing stock create pricing patterns that differ from Dallas, Houston, or Austin. Here are the factors that move your final number up or down.
- Peak-season demand. San Antonio summers routinely push temperatures past 100°F from June through September. During those months, repair demand spikes and wait times extend. Some companies add peak-season surcharges. We don’t. Your written price in July is the same as your written price in February.
- System age and warranty status. A 4-year-old system under manufacturer warranty costs less to repair than a 14-year-old system where every part is out of coverage. When a repair on an older system exceeds roughly 40% of replacement cost, replacement usually makes more sense.
- Equipment brand and parts availability. We service nine major brands, and parts for Carrier, Trane, and Lennox are typically easier to source quickly in San Antonio than some specialty components. A less common part often means a higher price and a longer wait.
- System size and home square footage. Installation costs scale with tonnage. A 2-ton system for a 1,200-square-foot home in Leon Valley will cost less than a 5-ton system for a 3,500-square-foot home in The Dominion. More tonnage means more equipment, more refrigerant, and more labor.
- Access and installation difficulty. Attic installations dominate in many San Antonio neighborhoods, especially in older Stone Oak and Alamo Heights homes. Tight attic access, low clearance around the air handler, and older ductwork that needs adapting all add labor hours.
- Ductwork condition. Leaky or undersized ducts are common in homes built before 2000. If your install requires duct modifications or sealing, that adds $500 to $2,500 depending on the scope. A good install quote will always flag this before work starts.
One thing that doesn’t affect our pricing: how your house looks when we arrive, or whether you have kids, dogs, carpets, or hardwood. We bring shoe covers and drop cloths on every visit because that’s part of the Cedarwell Care Promise, not an add-on charge. Luis Serrano and the rest of the Meadowsweet crew follow the same C.A.R.E. values on a $150 capacitor replacement as they do on a $7,500 full install.
How to Save on HVAC in San Antonio
Smart homeowners don’t chase the lowest bid. They avoid the expensive surprises. Here’s how to keep your total HVAC spend down over the life of your system.
- Get an annual tune-up. A $80 to $200 tune-up in the spring catches small issues before they become $650 repairs in August. Coil cleaning alone can restore several points of efficiency, which lowers your CPS Energy bill every month.
- Request a written price before work starts. If a company won’t put the number in writing before they start turning wrenches, walk away. You should know the cost of the repair before it happens, not after.
- Replace filters on schedule. In San Antonio’s dusty environment, a clogged filter forces your blower to work harder and can cause coils to freeze in the summer. This is the cheapest preventable repair there is. Plan for a filter change every 30 to 60 days during peak cooling season.
- Know when repair beats replacement. The rough rule we give San Antonio homeowners: if the repair cost multiplied by the system’s age in years exceeds $5,000, start thinking replacement. A $400 repair on a 10-year-old system? Fix it. A $900 repair on a 16-year-old unit? That money is better spent toward a new system with a fresh warranty.
- Ask about system sizing, not just price. An oversized system costs more upfront and runs inefficiently by short-cycling. A properly sized system lasts longer and costs less per month. Any reputable installer in San Antonio will do a load calculation before recommending a replacement.
- Get multiple quotes, but compare them honestly. A $6,500 bid with duct sealing and a new pad is not the same as a $5,800 bid without them. Look at what’s included, not just the bottom line.
If you’d like a free estimate on a repair or replacement, call (254) 271-2545. A live person answers. No voicemail queue, no automated trees, no waiting for a callback. That’s been true since the Cedarwell family of HVAC companies was founded in 2004, and it’s still true today.
How HVAC Installation Works: What to Expect
Whether you’re replacing a failed unit in Stone Oak or planning a proactive upgrade in Helotes, here’s the process we follow on every installation. This is the same sequence Luis Serrano and the crew use on every job, from a small condo unit to a large two-stage system.
Step 1: In-Home Assessment and Load Calculation
We measure the home’s square footage, check the existing ductwork, inspect the electrical panel, and ask about your comfort patterns. Which rooms run warm? Do you have pets that shed heavily? Is anyone home during the day? The answers shape the equipment recommendation. This visit is free.
Step 2: Written Quote with Line-Item Pricing
You receive a written price covering equipment, labor, removal of the old unit, refrigerant, and any ductwork or electrical work needed. Nothing is left as an “undefined scope.” The number you approve is the number you pay. The Cedarwell Care Promise requires this on every job, and it has since 2004.
Step 3: Installation Day
Our background-checked, uniformed technicians arrive on time. Shoe covers go on at the door. Drop cloths go down in every work area and walkway. If we need to move a pet’s water bowl or a kid’s toy bin, we ask before touching it. That’s part of the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, Explain the price before the work.
Step 4: Startup Testing and Clean-Up Photo
Before leaving, we run the system through a full startup sequence: refrigerant levels, airflow, thermostat wiring, and drainage. Then we clean the work area, take a photo of the clean-up, and show it to you before we drive away. That photo isn’t a nice-to-have. It’s part of every job.
Step 5: 365-Day Done Right Promise
If anything about the installation isn’t done right within a year, we make it right. No runarounds, no fine print. That promise applies to every repair and every install, and it’s the reason most of our San Antonio customers don’t shop around when the next issue comes up.

What to Check Before Calling for HVAC Service
Before you pick up the phone, there are a few things you can check safely from the ground or inside the house. These won’t replace a technician, but they’ll help you describe the problem accurately and may save you a diagnostic fee if the fix is simple.
- Check your thermostat. Make sure it’s set to “cool” or “heat” correctly, that the batteries aren’t dead, and that the set temperature is actually lower than the room temperature in summer or higher in winter. You’d be surprised how many service calls in San Antonio end with a thermostat battery replacement.
- Check the filter. A completely clogged filter can cause a system to overheat and shut down. If it’s dark and clogged, swap it out and try the system again before calling.
- Check the circuit breaker. San Antonio’s frequent summer thunderstorms can trip breakers. Find your electrical panel and look for a breaker labeled “AC” or “air handler.” If it’s tripped, flip it fully off, then back on. Do this only once. If it trips again immediately, that’s a sign of a deeper electrical issue and it’s time to call.
- Check for ice on the indoor or outdoor unit. If you see ice on the copper lines or the outdoor coil, turn the system off and call a technician. Running it in that state can cause compressor damage, which turns a $200 issue into a $1,500 one.
- Listen for unusual noises. A loud hum, a grinding sound, or a screeching noise from the outdoor unit points to a specific component failure. Describe the noise when you call. It helps us bring the right part on the first trip.
One word of caution on electrical troubleshooting: never open the service panel on your outdoor unit or indoor air handler yourself. Capacitors inside can hold a dangerous electrical charge even when power is off. That’s a job for a trained technician with the right tools. If the breaker keeps tripping or you see any signs of burnt wiring, call us at (254) 271-2545 and we’ll walk you through the next step on the phone.

If your furnace is acting up, call (254) 271-2545 and we’ll give you a written diagnosis and price before any repair work starts.
How much does a new AC system cost in San Antonio?
A new AC installation in San Antonio costs $3,500 to $7,500 for a complete system replacement in 2026. The range depends on system size, efficiency rating, brand, and the condition of your existing ductwork. A basic 3-ton system in a modest Leon Valley home might land near $4,000. A high-efficiency 5-ton system with duct modifications in a larger Stone Oak home can exceed $7,000. We also service all nine major brands we install: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Call (254) 271-2545 for a free in-home assessment and a written quote with no obligation.
How much is an HVAC tune-up in San Antonio?
An HVAC tune-up in San Antonio costs $80 to $200 depending on whether you’re servicing cooling only, heating only, or both. A cooling-only tune-up in the spring runs around $80 to $120. A heating and cooling tune-up together runs closer to $150 to $200. We recommend a spring cooling check and a fall heating check, especially given how hard San Antonio systems work from May through October. If you haven’t had your system serviced this year, call (254) 271-2545 to schedule a tune-up before the next heat wave.
Is it cheaper to repair or replace my HVAC system?
For San Antonio homeowners, the break-even point is usually when a repair costs more than 40% of a replacement system’s price, or when the system is past 12 to 14 years old. A $500 repair on a 7-year-old system? Repair it. A $1,400 repair on a 16-year-old system that you’d replace for $6,000? Replace it. The new system comes with a manufacturer warranty, better efficiency, and lower monthly CPS Energy bills. If you’re not sure where your system falls, call (254) 271-2545 and we’ll give you an honest assessment of both options, with written pricing for each.
Can you repair my HVAC system the same day in San Antonio?
In most cases, yes. For common failures, we carry the parts our technicians see most often in San Antonio: capacitors, contactors, ignitors, flame sensors, and pressure switches. When the right part is on the truck, the repair is completed in a single visit. For less common parts, we can usually source them same-day or next-day from local San Antonio supply houses. If your system is down and you need help fast, call (254) 271-2545. A live person answers 24/7 and can get you on the schedule the same day.

What Our Customers Say
"Replaced a failing capacitor and cleaned the unit. What I noticed was how respectful he was of the house and how spotless he left the utility closet. Fair price too."
- Tomas Rivera"Good repair. It needed a second visit because the part wasn't on the truck, which was a little inconvenient. Both times the tech was careful and clean and kind though."
- Chad Boone"New AC install. The crew protected the hallway floors the whole way to the attic and vacuumed up after. They worked quietly around my son's online classes without me even asking."
