Emergency AC Repair in Stockton

Emergency AC repair in Stockton

If the AC dies on a 100 degree afternoon, check the breaker and the thermostat. Then pull the filter and call. If anyone at home is elderly or unwell, get them somewhere cool first and fix the AC second.

The first ten minutes

Look at the thermostat. Is the screen on? Is it set to cool and below the room temperature?
Check the breakers. The outdoor unit and the indoor unit usually have their own. Reset a tripped one once. If it trips again, leave it off.
Pull the filter. If it is gray and matted, replace it.
Look for ice on the copper lines at the outdoor unit or on the indoor coil. If you see it, set the system to off with the fan on and let it thaw for a few hours.
Check for a PG&E or Lodi Electric outage if the whole house or the block is dark.

Keeping people safe while you wait

The National Weather Service lists the signs of heat exhaustion: heavy sweating and cold, clammy skin. A fast weak pulse, nausea and dizziness are signs too. Heat stroke is an emergency, with a body temperature of 103°F or higher, hot red skin, a fast strong pulse and confusion. Call 911 for heat stroke.

Close the blinds on the sunny side and stay on the lowest floor. Drink water. Use fans to move air. Stockton evenings help here: July nights at the airport average about 61.1°F, so once the outside air is cooler than inside, open windows on opposite sides of the house. During declared heat waves San Joaquin County opens cooling centers at libraries and community centers; the county lists them on sjready.org.

What to tell the HVAC company

What the system is doing: dead, running but warm, iced, leaking, noisy.
Whether the outdoor unit runs, and whether its fan spins.
How old the system is, if you know.
Who is at home. Say so if someone is elderly or has a health condition.

After-hours and weekend calls

Many HVAC companies charge more for visits at night or on weekends. Ask what the after-hours fee is before they come out. If the house can stay safe until the next morning, waiting may save money. If it can't, don't wait.

How hot it gets matters for that decision. The airport now averages 29.2 days a year at 100°F or more, and 2024 had 49. The hottest reading on record there is 115°F. What to do when the AC quits in a heat wave.

Questions Stockton homeowners ask

Is a broken AC an emergency?

It is when someone at home is at risk from the heat: older adults, infants, people with heart or lung conditions, or anyone showing signs of heat illness. Move them somewhere cool first.

Should I keep running an AC that is frozen?

No. Turn the system off and run the fan so the ice melts. Running it frozen can damage the compressor.

Does it cost more to get AC repaired at night or on a weekend?

Often, yes. Ask the company what their after-hours fee is when you call.
