AC Repair in San Diego

Emergency and after-hours calls taken after 5pm and on weekends.
Troubleshooting first, then the repair
A repair is only as good as the diagnosis in front of it, which is why troubleshooting and repairs sit side by side on our air conditioning list.
Common symptoms and what they usually point at
- Running but not blowing cold air. Usually airflow, refrigerant, or an outdoor unit that is not actually running. A silent outdoor unit while the indoor fan blows points at the electrical side.
- Running all the time and never catching up. Restricted airflow, a dirty filter or coil, low refrigerant, or a system that is undersized for the space.
- Ice on the lines or the indoor coil. Usually restricted airflow or low refrigerant. Turn the system off and let it thaw rather than running it frozen.
- Water around the indoor unit. Almost always the condensate drain, not a leak in the sealed part of the system.
- Turning on and off in short bursts. An electrical fault, a refrigerant problem, or a system that is oversized for the space.
- New noises. Grinding, squealing or rattling usually means a fan, a motor or another moving part is on its way out.
None of those is a diagnosis on its own. They are what to tell us when you call.
Worth checking before you call
Check that the filter is not clogged, that the breaker for the outdoor unit has not tripped, and that the outdoor unit is not boxed in by plants or stored items. If one of those was the problem, you have saved a visit.
Repair or replace?
When the same system keeps needing repairs, or a major component fails on an older system, replacement becomes the more sensible conversation. Installation and removals are on the same list, so that conversation stays with the same team. See AC installation and replacement.
Maintenance
Maintenance is on the list too. A system that is looked at ahead of the season it works hardest in is less likely to be the one that stops in the middle of it.
What to expect
- Call or send the form. Say what kind of system it is and what it is doing.
- Estimate by phone. Air conditioning is usually estimated by phone.
- Troubleshooting, then the repair. The fault is found before anything is replaced.

AC repair questions
Why is my AC running but not blowing cold air?
Usually airflow, refrigerant, or an outdoor unit that is not actually running. A silent outdoor unit while the indoor fan blows points at the electrical side. Cold air at the register in a room that never catches up points at distribution instead.
Why is water dripping from my indoor unit?
Almost always the condensate drain, not a leak in the sealed part of the system. Cooling removes moisture from the air, and that water leaves through a drain line. When the line blocks it finds another way out, and many systems shut themselves off when it does.
Why is there ice on my AC lines?
Usually restricted airflow or low refrigerant. Turn the system off and let it thaw rather than running it frozen, then check the filter. If the ice comes back, the cause is still there.
