Homeowner First Response

System won't turn on

When nothing happens at all, it's often something simple. Check these and tell us what you find.

Don't want to answer questions? That's fine. Skip them and go straight to scheduling.

1Does the thermostat screen light up?

Tip: Look for a low-battery symbol on the screen. If you see one, change the batteries.

2Is there water in the drain pan or around the float switch?

Tip: The drain pan sits under the indoor unit. When it fills, the float switch shuts the system off on purpose to prevent a leak. If it's full, turn the system off and tell us.

3Is the air filter dirty?

Tip: If it's gray and you can't see light through it, replace it. A clogged filter causes more problems than anything else. See Air filters: how often and why.

4What size is your air filter?

Tip: The size is printed on the edge of the filter. With it, our technician can bring the right filter.
