lennox ac question
I have a Lennox A/C unit. The furnace is sepperate in the attic and the a/c is outside.
The fan blows cool air, but it is having problems keeping the house at what the thermostat is set for.
I checked the a/c outside. A brass fitting connected to the a/c was frosted over.
I have read several threads. Several are similar problems, but not exact. could this be a capacitor? If so, where is it located in the unit? how do i test it (i don't have any meters)? and how do i replace it?
Thanks in advance,
