I know very little about heat pumps so would like to ask some advice before I call out a engineer to fix my problem.
I have a CPLE24-1C Goodman 10 Seer 2-Ton heat pump.
When the temperature drops one degree below the set temperature - cold air is blown through the vents.
Then when it drops another degree the auxiliary light on the thermostat comes on and heat is provided until the set point is reached.
So two questions really:
1) Does anyone know why cold air is being blown through on the primary level of heat?
2) Whilst waiting for the repair - which is the more economical setting to run - the current setting - or set it to the emergency heating method (compressor off with auxiliary heat)?
Many thanks for any help.
