HVAC Repair Runs $95 to $4,500, Depending on the Problem
That’s a wide range, and there’s a reason for it. HVAC repair splits into two very different buckets, and which bucket your system lands in decides almost everything about the price.
The first bucket is wear parts. Capacitors, contactors, condenser fan motors. These are small components that age out. They’re the most common repairs we do, and they sit at the low end of the range. A capacitor replacement is $175. In San Antonio these fail more often than people expect, because a condenser sitting in full afternoon sun runs long hours from May through September. Heat is hard on electrical parts.
The second bucket is major components. Compressors, coils, heat exchangers. These usually go on older systems, or on systems that were installed wrong from the start. That’s where you get into the top half of the range. We find a fair number of installation problems during repair calls: line sets that are undersized, return ducts too small for the equipment, an outdoor unit crammed against a fence with no clearance. Those don’t cause a failure on day one. They cause it in year eight.
Here’s what drives your number up or down: 
- Which part failed, and whether it’s a wear component or a major one
- Whether the failed part damaged something else before we got there
- Age of the system and whether replacement parts are still made for it
- Refrigerant type, since older refrigerants cost more per pound
- How the system was installed originally, including ductwork and electrical
The $89 trip fee covers the visit and the diagnostic work. We test the system, find the problem, and tell you what we found. Then we build you a written estimate at no charge. Nothing gets fixed until you look at that number and say yes. If you decide not to move forward, you’ve paid the $89 and nothing more.
We don’t offer financing on repairs. Financing is available on new AC and heating installations, not on repair work. So if a quote comes back at the high end and paying it at once isn’t workable, that’s a real factor in deciding what to do next.
A mistake we see a lot around San Antonio is waiting through a hot spell with a system that’s already struggling. A unit running non-stop with a weak capacitor or a dirty condenser coil puts extra strain on the compressor. The small repair is cheaper than what it can turn into.
What Drives Your Price Up or Down
The single biggest thing that moves your price is which part failed. Wear parts sit at the bottom of our $95 to $4,500 range. Major components sit at the top. A capacitor replacement runs $175. A failed compressor or a leaking evaporator coil lands in the thousands, because the part costs more, the refrigerant costs more, and the job takes hours instead of minutes.
Age matters too, but not the way people expect. Older systems don’t cost more just for being old. They cost more because the parts that fail on a 14-year-old system tend to be the expensive ones. On a 5-year-old system we’re usually replacing a contactor or a condenser fan motor. On an older system we’re more often looking at sealed-system work.
Here’s a list of what we see change a repair price on real San Antonio service calls:
- Wear part versus major component. Capacitors, contactors, and condenser fan motors are the common, lower-cost failures. Compressors, coils, and control boards are the expensive ones.
- Refrigerant type and amount. R-22 systems cost more to recharge than newer systems, and a large charge on a big home adds up fast.
- Access. A condenser sitting in a tight side yard with a fence two feet away takes longer than one out in the open. An attic furnace in a 110-degree San Antonio attic with a narrow walkway is slower work than a garage unit.
- Whether the original install was done right. Undersized line sets, missing drain traps, and blower wheels installed backward all turn a one-part repair into a longer job.
- How many separate problems the system has. A system that’s low on charge and has a weak capacitor is two repairs, not one.
One thing that shows up constantly in this city is the condensate drain. Our hard water and the dust that blows through in spring pack those lines with sludge. A clogged drain trips the float switch, the system shuts off, and the homeowner assumes the compressor died. That’s a cleaning, not a major repair. We’d rather tell you that than sell you something bigger.
A mistake we run into a lot: someone pulls the disconnect or flips the breaker off and on several times trying to restart the unit. On a system with a weak capacitor, that can stress the compressor. If your unit isn’t running, leave it off and call. Repeated restarts don’t fix anything and can push a $175 repair into a much larger one.
What doesn’t change your price is the diagnosis. We charge an $89 trip fee to come out, test the system, and find the problem. After that, the estimate is free and you see the number before we touch anything. If you say no, you’ve paid the $89 and nothing else.
What’s Included in Our $89 Trip Fee (and What’s Not)
The $89 trip fee covers the drive out, the diagnostic work on your HVAC system, and a report of what we find. It also covers the written estimate, which is free. You pay $89 to learn what’s wrong. You don’t pay anything extra to find out what the fix costs.
Here’s how that visit runs. You call or chat in to book service, and most of the time we get there the same day. The technician runs diagnostics on the system, then walks you through what he found. Then we build the quote. Nothing gets repaired until you approve the price in writing.
What the $89 does not include is parts or labor for the repair itself. A capacitor replacement, for example, runs $175 as a finished job. The trip fee isn’t a deposit on that number and it isn’t a hidden add-on either. It’s a separate line, and you’ll see both before you say yes.
So the fee covers:
- Travel to your home anywhere in our San Antonio service area
- Full HVAC system diagnostics, indoor and outdoor
- A plain-language report of what we found and why it failed
- A free written estimate for the repair
- A walkthrough of the completed work and how the system is running, once you approve and we finish
It doesn’t cover parts, refrigerant, or repair labor. Those are quoted separately. We also don’t offer financing on repairs, so there’s no payment plan to ask about. Big-ticket major component failures are the ones where that matters most, and we’ll say so during the report instead of at the end.
One thing worth knowing about diagnostics in this city. A lot of San Antonio homes have the air handler in an attic that hits 130 degrees in August, and the condensate drain line runs a long way before it exits. Clogged drain lines and float switches tripping are a routine find here. So are outdoor coils packed with cottonwood fluff and lawn clippings from a mower blowing toward the unit. Those get checked on the same trip fee, because a coil that can’t breathe looks a lot like a failing compressor until somebody reads the pressures.
A common mistake before calling is replacing the thermostat first. People buy a smart thermostat, wire it in, and the system still won’t cool. Usually the thermostat was fine. If you’ve already swapped one, tell the technician, since a miswired low-voltage connection changes what we test first.
If you’d rather see a number before anyone drives out, call and describe what the system is doing. We can talk through the likely range over the phone. The estimate itself still comes free after the diagnostic, because guessing at a repair price sight unseen isn’t useful to either of us.

The Most Common Repair and What It Runs
The repair we do more than any other is a capacitor replacement, and we charge $175 for it. That’s the part and the labor. It’s the small cylinder that gives the compressor and fan motor the push they need to start. Texas heat cooks them. We pull swollen, leaking capacitors out of systems all summer long in San Antonio, sometimes on units that are only four or five years old.
Here’s how that fits into the bigger picture. HVAC repair at our shop runs from $95 to $4,500. Most homeowners land closer to the bottom of that range than the top, because most failures are wear parts.
There are really two kinds of HVAC repair, and the price gap between them is huge.
- Wear components. Capacitors, contactors, condenser fan motors, ignitors, and similar parts. These wear out on a schedule the way brake pads do. They’re inexpensive, they’re usually in stock on the truck, and they’re the majority of what we replace.
- Major components. Compressors, evaporator coils, heat exchangers. These sit at the top of the range. They tend to fail when a system is getting older, or when the system was installed wrong in the first place and has been fighting itself for years.
That second category is worth understanding before you call anybody. When we open up a condenser and find a burned contactor with pitted contacts, that’s a $200-ish afternoon. When we find a compressor that’s gone to ground, we’re having a different conversation, and part of that conversation is whether repairing a 12-year-old system even makes sense.
What moves your number up or down: which part failed, whether the system is under a manufacturer warranty, how accessible the equipment is, and whether one failure caused a second one. A capacitor that goes out and gets ignored for a week can take the fan motor with it. We see that a lot. The homeowner hears the unit humming, figures it’s just struggling in the heat, and waits.
A mistake we run into on service calls is people replacing a capacitor themselves off a parts-store shelf without matching the microfarad rating. The wrong rating runs the motor hot and shortens its life. It’ll cool the house for a while. Then you’re buying a motor.
Our trip fee is $89. That covers the visit and the diagnostic work on your system. After we diagnose it, we tell you exactly what we found and build you a free estimate before we touch anything. You see the price first. If you don’t want the work done, you don’t get the work done, and you’re out the trip fee and nothing else.
If we do the repair, we go through the completed work with you and show you the system running before we leave. You should be able to see and hear what changed.
What Happens Before We Charge You for Any Repair
You see a price before we touch a single part. The only charge that comes before that price is the $89 trip fee, which covers the drive out and the HVAC repair diagnostics on your system. Everything after that is your call.
Here’s the order it happens in. 
- You call or chat in to book service. Most of the time we can get out the same day.
- The technician runs diagnostics on the system.
- We report the findings to you and explain what we found.
- We build a free estimate before any work is done.
- You approve it, or you don’t. Nothing gets repaired until you say yes.
- If you approve, we do the repair and balance the system.
- We walk you through the completed work and show you the system running.
That walkthrough matters more than people expect. A capacitor swap takes a few minutes, and a lot of homeowners never see what was replaced or what the system is doing now. We show you the part, the readings, and the air coming out of the vents before we leave.
The free estimate is a written number, not a ballpark over the phone. If your repair is a $175 capacitor replacement, that’s what the estimate says. If diagnostics point to a major component like a compressor, the estimate says that too, with the real figure attached. Repairs on our systems run anywhere from $95 to $4,500, and we’d rather you see the high end on paper than hear it after the fact.
One thing worth knowing about San Antonio houses. In August, we get a lot of calls where the unit is running but the house won’t cool below 80. Homeowners assume it’s low refrigerant. Often the diagnostic turns up a filter that hasn’t been changed since spring, a condensate drain packed with algae, or an outdoor coil caked with cottonwood fluff and grass clippings from the mower. Those findings go in the report whether they’re the main problem or not.
A mistake we see a lot: people flip the breaker off and on several times before calling. When a compressor is already struggling, repeated restarts add heat and stress. If your system trips the breaker, leave it off and call. It saves the diagnostic time and sometimes saves the part.
We also won’t quote work we can’t verify. If a technician can’t get eyes on a component or the readings don’t line up, we say that in the report instead of guessing at a price. A quote built on a guess isn’t useful to either of us.
Frequently Asked Questions
Common questions about HVAC repair
Does the $89 trip fee get subtracted from the repair cost if I go ahead?
No, the $89 trip fee is a flat charge for the visit and diagnostic work. It stands on its own whether you approve the repair or not. The written estimate for the actual fix is free, so you’re only ever paying for the diagnosis once. If you say yes to the repair, you pay the $89 plus the repair price on the estimate.
Can I get a quote over the phone before you come out?
No, we need to test the system in person before we can give you a real number. HVAC repair prices depend on which part failed and why, and that only shows up during a diagnostic visit. The $89 trip fee covers that visit and the written estimate afterward. Guessing a price without seeing the system would risk being wrong in either direction.
Why did my neighbor’s capacitor repair cost the same as mine but another repair cost thousands more?
It comes down to which bucket the repair falls into. Capacitors, contactors, and condenser fan motors are wear parts that fail often and cost less, like the $175 capacitor replacement. Compressors, coils, and control boards are major components that cost more in parts, refrigerant, and labor time. Two repairs on the same brand of system can land far apart in price for this reason.
Is it worth paying the $89 fee if I might just decide to replace the system instead?
The diagnostic visit still gives you real information either way. We test the system, tell you what failed, and give you a free written estimate before anything gets fixed. That report tells you whether you’re looking at a wear part or a major component, which is useful even if you end up deciding to replace instead of repair.
Will you push a bigger repair on me if the real problem is something small?
No. A common example is a clogged condensate drain, which trips the float switch and shuts the system off. People often assume that means the compressor failed, but it’s a cleaning, not a major repair. We report what we find and price the estimate to match, not to the bigger problem you might be expecting.
Do you offer financing if a repair estimate comes back high?
No, we don’t offer financing on repair work. Financing is available for new AC and heating installations, but not for repairs. If a repair estimate lands at the high end of our $95 to $4,500 range, that’s worth factoring into your decision before you approve the work.
