Customer Question
My a/c unit quit...

My a/c unit quit working but my fan (squirrel cage) kept blowing and the heat worked. now the fan does not come on and the heat doesn't either

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

The thermostat has caused problems before but i set it high and nothing. Filters are clean

Contractor's Assistant: Do you plan on doing the work yourself?

Yes, my daughter went to electrical school for a bit and she fixes her stuff.

Contractor's Assistant: Anything else we should know to help you best?

There would be no heat if the fan won't blow, right? if the fan was working would that make the heat come on?

ok, but it will be later, I am at work. but I was wondering if the fan doesn't work then there will be no heat, right? If the fan is working would the heat come on?
HVAC Technician: Phil, Mechanical Engineer replied 7 months ago

If the fan does not work there will be no heat.

If the fan is working the heat may or may not come on, depending on whats wrong with the heater, a bad gas valve or printed circuit board can give that and a wide range of other symptoms
