Air Conditioning Repair

When the house will not cool, you need a real diagnosis instead of guesswork. We repair central AC, heat pumps in cooling mode, ductless mini-splits, and light commercial rooftop units throughout the Bay Area.

Common problems we fix

  • System blows warm air or never reaches the set temperature
  • Outdoor unit hums, buzzes, or will not start
  • Frozen evaporator coil or refrigerant line ice
  • Weak airflow, short cycling, or noisy operation
  • Clogged condensate drain, water around the indoor unit, or float switch trips
  • Failed capacitors, contactors, motors, sensors, boards, or thermostats

Our diagnostic approach

  1. Listen first: We ask what changed, when the issue started, and what the system is doing now.
  2. Test the basics: Thermostat call, power, safeties, airflow, filter, drain, and outdoor unit operation.
  3. Measure the system: Temperature split, refrigerant pressures where needed, electrical readings, and component performance.
  4. Explain the fix: You get an upfront repair quote before work begins.
  5. Verify operation: After the repair, we run the system and confirm it is cooling properly.

Repair or replace?

If the repair is straightforward, we will say so. If the AC is older, leaking refrigerant, or facing a major compressor/control failure, we can compare repair cost against replacement options so you can make a calm decision.

Wondering If We Cover Your City?

Our services are just as easy to schedule across multiple parts of the Bay Area. In the South Bay, we serve San Jose, Sunnyvale, Los Gatos, Saratoga, Campbell, Cambrian Park, Cupertino, Mountain View, Los Altos, Palo Alto, and Menlo Park.

On the Peninsula and the West Bay, we provide the same convenient support in Atherton, Redwood City, San Carlos, Belmont, Foster City, and surrounding areas. In the East Bay, we’re available in Fremont, Newark, Milpitas, and Union City—so wherever you are in our service area, help is close by and simple to book.

If you’re not sure whether we cover your neighborhood, just reach out—give us a call or submit a request online. It’s quick, easy, and completely free, and we’ll confirm availability and next steps right away.
