Before you call
Quick checks you can do yourself
- Set the thermostat to Cool, lower the setpoint below room temperature, and replace the batteries.
- Check the main electrical panel for tripped AC or furnace breakers. Reset once only.
- Check that the outdoor disconnect is On and that the switch near the furnace or air handler (it looks like a light switch) is On.
- Look at the condensate drain pan and float switch. If water is backed up, clear it before expecting the system to start.
- Make sure the furnace or air handler panel door is fully closed so the door switch is pressed.
- After any reset, wait 5 to 10 minutes. Many systems have a built-in delay.
Still not working? Call (323) 240-2373 or tap "Call me back". Do not open electrical panels or touch gas parts.

Troubleshooting
AC Not Turning On? 6 Causes and Easy Checks
When an AC will not turn on, start with the thermostat (mode, setpoint, batteries), then the breakers, the outdoor disconnect, and the condensate float switch. If power and settings are fine and nothing starts, the problem is likely a failed control board, transformer, capacitor, or contactor, which a technician should test.

Heat Pump Blowing Cold Air in Heat Mode? Causes
A heat pump that blows cool air in heat mode may simply be in defrost mode, which is normal and lasts a few minutes. If it blows cold air for a long time, check the thermostat mode and filter, then call a technician for possible reversing valve, defrost control, or refrigerant leak problems.

AC Short Cycling? Turns On and Off Every Few Minutes
An AC that turns on and off every few minutes is short cycling. Common causes are a thermostat in a bad spot, a clogged filter, a frozen coil, a tripped float switch, an oversized system, or an electrical or refrigerant problem. Check the thermostat and filter first. If it keeps cycling, have a technician test it, because short cycling wears out the compressor.

Thermostat Blank or Not Responding? Causes and Fixes
A blank thermostat usually has dead batteries, lost power from a tripped breaker or switch, or was shut off by a tripped condensate float switch. It can also be a blown fuse on the control board or a failed transformer. Replace the batteries and check breakers and the float switch first. If it is still blank, a technician should test the low voltage power.

High Electric Bill in Summer? Why Your AC Runs Too Much
A high summer electric bill usually means the AC is running longer than it should. Common causes are a dirty filter or coils, leaky ducts in a hot attic, a low setpoint, poor attic insulation, a refrigerant leak, or an old, inefficient system. Start with the filter, thermostat schedule, and outdoor coil, and have the system checked if run time is still high.

Batteries, a tripped float switch or a blown fuse.
Says cooling, nothing happens
Could be wiring or the equipment itself.

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.
