Before you call
Quick checks you can do yourself
- Set the thermostat to Off for cooling and switch the fan to On. Let it run 2 to 4 hours, or until all ice is gone. Do not chip or scrape the ice.
- Put towels down near the indoor unit. Melting ice makes a lot of water fast.
- Replace the air filter while the system is thawing.
- Open all supply vents and make sure return grilles are not blocked.
- Once fully thawed, turn cooling back on and check it over the next few hours. If ice comes back, turn it off and call.
- If you smell burning, turn the system off at the thermostat and switch off its breaker. Do not turn it back on until it has been checked.
Still not working? Call (323) 240-2373 or tap "Call me back". Do not open electrical panels or touch gas parts.

Troubleshooting
AC Frozen? Ice on the Lines or Coil: Causes and Fixes
An AC freezes when the indoor coil gets too cold, usually from low airflow (dirty filter, closed vents, weak blower) or low refrigerant from a leak. Turn cooling off and run only the fan to thaw it, replace the filter, and if it freezes again, call a technician to check airflow and refrigerant.

AC Smells Bad? Burning, Musty or Dirty Sock Smell
A musty or dirty sock smell usually comes from mold or bacteria on the indoor coil, drain pan, or ducts. A burning or electrical smell can mean an overheating motor or wiring and is urgent: turn the system off at the thermostat and the breaker, and call a technician. A rotten egg or gas smell means leave the house and call SoCalGas or 911.

Tip
When it makes sense to upgrade
Smoky days
A higher grade filter helps, if the blower can handle it.
Allergies
Seal leaky returns and upgrade the filter.
Filter clogs fast
Common in the valley. A thicker media filter lasts longer.
Dust after cleaning
Usually return leaks in the attic.
Pro tip
Do not jump to the highest MERV filter. If the system cannot push air through it, comfort drops and parts fail.

Studio City, CAI don’t have enough good things to say about WY&G. They are professional, fast, and do quality work.

They are great with communicating and always called me back promptly. I will definitely be using them again.
