Common AC problems in Poway homes
Central air conditioners tend to fail in a few familiar ways, and most of them show up on the first hot afternoon of the year. Knowing the likely cause helps you describe the problem when you call.
Failed capacitor
The capacitor gives the compressor and outdoor fan motor the jolt they need to start. When it weakens, the outdoor unit hums but the fan doesn’t spin, or the system starts and stops. It is one of the most common repairs, especially after a run of hot days.
Low refrigerant from a leak
Refrigerant isn’t used up like fuel. If the level is low, there is a leak somewhere in the lines or coils. A low charge makes the system run longer, cool less and sometimes freeze the evaporator coil. Topping it up without finding the leak only buys time.
Frozen evaporator coil
Ice on the indoor coil or the copper line usually points to restricted airflow (a clogged filter or blocked return) or low refrigerant. Turn the system off and let it thaw before anyone tests it.
Clogged condensate drain
Your AC pulls moisture out of the air and drains it away. When the line clogs, water backs up into the pan, and many systems have a float switch that shuts the AC off to prevent a leak.
Thermostat or electrical faults
Dead batteries, a tripped breaker or a loose wire can look like a broken AC. These are worth checking before you call.
Quick checks you can do safely
A few simple checks rule out the easy causes. Stop if anything looks burnt, smells like gas or involves opening panels.
- Set the thermostat to Cool and a few degrees below room temperature, and replace its batteries if it has them.
- Check the breaker panel for a tripped AC or furnace breaker. Reset it once; if it trips again, leave it off and call.
- Look at the air filter. A gray, clogged filter can cut airflow enough to freeze the coil.
- Make sure supply vents are open and the outdoor unit isn’t blocked by plants or debris.
- If you see ice, switch the system to Fan only or off and let it thaw for a few hours.

When a repair stops making sense
Most AC problems are worth repairing. Replacement starts to make more sense when the system is older, the repair is a major part like the compressor or the outdoor coil, or the unit still uses R-22 refrigerant, which is no longer produced in the United States.
A common rule of thumb multiplies the age of the unit by the repair cost and compares the result with replacing it. Read repair or replace your AC for how that works, and what the rule leaves out. If you decide to replace, see AC installation and replacement in Poway.
FAQ
Common questions
Straight answers to what Poway homeowners ask most. Still unsure? Call (858) 898-5145.
Why is my AC running but not cooling the house?
The most common causes are a clogged air filter, a failed capacitor, low refrigerant from a leak or a frozen evaporator coil. Check the filter and thermostat first. If the outdoor unit hums without the fan spinning, or you see ice on the lines, turn the system off and call a technician.
Should I turn my AC off if it’s freezing up?
Yes. Switch the thermostat to off or Fan only so the ice can melt. Running a frozen system can damage the compressor. Once it has thawed, a technician can find out whether airflow or refrigerant caused it.
Is it worth repairing an old air conditioner?
Often, yes. Smaller repairs like a capacitor, contactor or drain line make sense on most systems. If the unit is older and needs a major part, or it uses R-22 refrigerant, compare the repair with replacement before you decide.
What does the contractor check during an AC repair visit?
Usually the thermostat, electrical parts such as the capacitor and contactor, refrigerant pressures, the evaporator and condenser coils, airflow and the condensate drain. They should tell you what they found and what the repair involves before starting.
Do you repair ductless mini-splits?
No. This service covers central air conditioning systems and gas furnaces.
