Warm air from the vents
The system runs but the air is not cold. Common causes are a failed capacitor or contactor, low refrigerant, or a frozen indoor coil. Check the filter first, then call.
AC repair in San Jose, CA
San Jose AC repair usually comes down to a handful of failures: a worn capacitor, a weak contactor, a dirty or iced coil, a clogged drain, a failing fan motor, or low refrigerant from a leak. We find which one it is, explain it in plain terms, and give you the price before any repair begins.
Emergency service is available 24/7.
Quick answer: what does AC repair cost in San Jose?
Most San Jose AC repairs fall between about $280 and $650, with larger repairs such as a coil or compressor running $1,600 to $3,200. A diagnostic service call is typically $99 to $149.
The actual price depends on what failed, how old the system is and how hard it is to reach. The full breakdown is below, and our AC repair pricing guide has the numbers for every city we serve.
Examples of our work
Signs your AC needs repair
Weak airflow
A clogged filter, a failing blower motor, a blocked return or leaking ducts. Weak airflow can also freeze the coil, which makes cooling worse.
Outdoor unit hums or will not start
A humming sound without the fan spinning often means a failed capacitor. Turn the system off at the thermostat and call. Forcing it can damage the motor or compressor.
Ice on the coil or refrigerant line
Switch cooling off and run only the fan to thaw it. Do not chip the ice. Ice points to low airflow or low refrigerant, and both need a technician.
Water around the indoor unit
Usually a clogged condensate drain. Turn the system off to avoid damaging ceilings and floors.
Short cycling or a very high bill
The system turns on and off every few minutes, or your electric bill has climbed with no change in how you use it. Either one means something is not working as it should.
Why San Jose air conditioners fail
San Jose's mild climate means many systems run only a few weeks a year, then run all day through a heat wave. Parts that have aged quietly while idle fail under that sudden load.
The most common failures we see are electrical: capacitors, which give the motors their starting push, and contactors, the switch that powers the outdoor unit.
Attic conditions matter too. Ducts that run through a hot attic lose cooling before the air reaches a room, and an older duct system that was never designed for air conditioning can leave bedrooms warm while the system runs flat out.
When we repair a system, we look at airflow and duct condition, not only the unit outside.
What happens on an AC repair visit
- You tell us what the system is doing. When did it stop, what did you hear or smell, was there a storm or power flicker. Details point the technician at the right place.
- We check the basics. Thermostat settings and power, the air filter, the breaker, and airflow at the vents.
- We test the system. We test electrical components with a meter, check refrigerant pressures, measure the temperature difference across the coil, check blower and fan motor performance, and look at the condenser coil and the condensate drain.
- We find the cause, not only the symptom. A failed capacitor can be a sign of a motor that is overheating. If we find a related problem, we tell you before we replace anything, so you do not pay for the same repair twice.
- You get the options and the price. We explain what failed, what it takes to fix, and what each option costs. If the repair is large on an old system, we also give you the replacement price so you can compare.
- We repair it and test it. We run the system and confirm it is cooling before we leave.

Repair or replace your San Jose AC?
There is no single rule. We look at the whole picture:
- Age. Systems around 10 to 15 years old are approaching the end of their life.
- What failed. A capacitor, contactor, drain or thermostat on a healthy system is a simple repair. A failed compressor or leaking coil on an old system is a different decision.
- Repair history. Several repairs in a short time suggest more are coming.
- Refrigerant. Older systems that use R-22 are costly to recharge because it is no longer produced. Systems installed before 2025 mostly use R-410A, and newer equipment uses lower impact refrigerants under federal rules.
- Comfort and ducts. If some rooms never cool, replacing the unit alone may not fix it.
- Your furnace. If the furnace is also old, a heat pump can replace both. See heat pump installation in San Jose.
We give you a repair price and a replacement price so the decision is yours. See AC replacement in San Jose.
What you can check yourself, and what to leave to us
A few checks are safe and can save you a visit:
- Make sure the thermostat is set to cool, set below the room temperature, and has power or fresh batteries.
- Check the breaker. If it tripped, reset it once. If it trips again, leave it off.
- Replace a dirty air filter and clear leaves or debris from around the outdoor unit.
Leave these to a technician: anything involving refrigerant, capacitors and other electrical parts, the compressor, or the safety controls. Refrigerant work requires federal certification, and capacitors hold a charge even when the power is off.
If you smell burning, see smoke or find water near electrical parts, turn the system off at the breaker and call.

Common questions
How much does AC repair cost in San Jose?
Most repairs run about $280 to $650. Major repairs such as a coil or compressor run $1,600 to $3,200. The diagnostic call is typically $99 to $149. Ask for the price before work begins.
Why is my AC running but not cooling?
The usual causes are a failed capacitor or contactor, a frozen coil from low airflow, low refrigerant, or a dirty condenser coil. Check the filter, then call us. Do not keep running a frozen system.
Why is my AC freezing up?
Ice forms when airflow is too low or refrigerant is low. A clogged filter is the easy cause. Switch cooling off, run the fan to thaw it, and call us if it comes back.
Should I fix my 15 year old AC or replace it?
It depends on what failed. A small repair on a system that otherwise works is often worth it. A compressor or coil failure on a 15 year old system usually points toward replacement. We give you both prices.
Do you work on all brands?
Yes, all makes and models. See brands we service.
Do you offer emergency AC repair in San Jose?
Yes, 24/7.
Can a heat wave damage my AC?
Yes. Long, hot days push a system hard, and weak parts such as capacitors and fan motors often fail then. A spring tune up catches many of them early. See the AC tune up pricing guide.
Do I need a permit for an AC repair?
Usually not for a repair. Replacing a system does need a permit in San Jose.
