The short answer

CoolVantage repairs central AC systems and heat pumps in Los Gatos homes. We test first and explain what failed and why. You choose the repair before we start.

When your air conditioner stops cooling on a hot Los Gatos afternoon, you want a clear answer about what's wrong and what it will take to fix it. CoolVantage Heating & Cooling repairs central air conditioners and heat pumps in homes across Los Gatos, in both the 95030 and 95032 ZIP codes. We're based in San Jose, about 6 miles away, so reaching you is a short drive. Our technicians find the actual cause, explain it in plain terms, and go over your options before any work starts.

Why AC Problems Show Up During Los Gatos Summers

The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay, and Los Gatos sits toward that warmer southern edge. During warm stretches, air conditioners here can run long cycles through the afternoon and into the evening.

Long run times expose weak parts. A capacitor that was borderline in spring may fail in July. A small refrigerant leak can go unnoticed in mild weather and become obvious once the system can't keep up. Many systems sit mostly idle through the cooler months, so the first hot week of the season is often when problems surface.

Common AC Problems We Fix

Most repair calls come down to a handful of causes. We test before we replace anything, so you don't pay for parts that weren't the problem.

  • Outdoor unit hums but the fan or compressor won't start, often from a failed capacitor or contactor
  • System runs but blows warm or lukewarm air, which can point to low refrigerant, a dirty condenser coil, or a compressor problem
  • Ice on the refrigerant lines or indoor coil, usually tied to restricted airflow or a low refrigerant charge
  • Water around the indoor unit from a clogged condensate drain or a damaged drain pan
  • Breaker trips when the AC kicks on
  • Thermostat isn't calling for cooling, or it calls and nothing happens
  • Short cycling, where the system turns on and off every few minutes
  • New rattling, grinding, or squealing from the outdoor fan motor or indoor blower

What Happens During a Repair Visit

The technician starts by asking what you've noticed. That includes when the problem began, whether it's constant or comes and goes, and any unusual sounds or smells. Then we check the thermostat, the air filter, the indoor blower and coil, the condensate drain, the electrical components in the outdoor unit, and the refrigerant pressures.

Once we find the cause, we explain what failed, why it likely failed, and what the repair involves. If more than one fix is reasonable, we walk you through the trade-offs. You decide before we do the work. We can often finish common repairs on the first visit if we have the part with us. These include capacitors, contactors, and drain clogs.

Repair or Replace?

A breakdown doesn't automatically mean you need a new system. If one part fails on an otherwise healthy unit, it's usually worth fixing. Replacement is worth discussing in a few cases. One is a failed compressor on an older unit. Another is a system that uses an outdated refrigerant that is getting harder to service. A third is a pattern of repairs season after season.

If replacement comes up, many homeowners look at heat pumps, which cool in summer and heat in winter. The federal Energy Efficient Home Improvement Credit (25C) does not cover installations after the end of 2025. Even so, BayREN and local clean energy providers may offer heat pump incentives. Those programs change by funding cycle, so we confirm what's currently available before including it in an estimate. We won't push a replacement when a repair makes sense.

Quick Checks Before You Call

A few simple checks can sometimes get cooling back or help us diagnose the problem faster. If you see ice on the lines or coil, turn cooling off and set the fan to On so it can thaw before the visit.

  • Confirm the thermostat is set to Cool and the setpoint is below room temperature, and replace its batteries if it uses them
  • Check the air filter and replace it if it's clogged
  • Look for a tripped breaker for both the indoor unit and the outdoor unit
  • Clear leaves, plants, and stored items away from the outdoor unit
  • Check whether the condensate drain line or pan is full of water

FAQ

Common questions

Don’t see your question? Call (669) 444-4876 and we’ll talk it through.

How soon can you get to my home in Los Gatos?

We're based in San Jose, about 6 miles from Los Gatos. Contact us and we'll give you the next available appointment time based on the current schedule.

Why is my AC running but not cooling the house?

Common causes include a clogged filter, a dirty outdoor coil, low refrigerant from a leak, or a failing compressor or capacitor. A technician needs to test the system to tell which one it is.

Should I keep running my AC if I see ice on it?

No. Turn cooling off and set the fan to On so the ice can melt. Running a frozen system can damage the compressor. Ice usually points to an airflow or refrigerant problem that needs a repair.

Do you repair heat pumps as well as central air conditioners?

Yes. Heat pumps provide cooling the same way air conditioners do, and we diagnose and repair both in Los Gatos homes.

Is it worth repairing an older air conditioner?

It often is if only one part has failed and the rest of the system is in good shape. If the compressor has failed or repairs keep piling up, we'll explain the costs and trade-offs of repairing versus replacing.

Are there rebates for AC repair?

Incentives generally apply to new heat pump installations, not repairs. The federal 25C credit no longer applies to installations after 2025. BayREN and local clean energy providers may offer current heat pump incentives, and we confirm availability before quoting them.
