Depending on what type of filter you have, basic 1” filter should be replaced every month. For 4”-5” media type filters refer to the manufactures spec sheet
How often should I have my unit/units service?
Manufactures require maintenance by a qualified technician at least once a year to validate the warranty. Without proof of maintenance, warranty claims can be denied. We recommend twice per year (Spring & Fall) this is also recommended industry wide.
What does the diagnostic charge cover?
Travel to the location and determining what the failure is. Does not include any testing or leak detection.
Why does my AUX heat come on while in heating mode when its real cold outside or I raise the temp?
Heat pump alone can not heat your home on cold days without the help of auxiliary heat. Heat pumps are used to maintain temperatures once you reach your desired setting. If the heat pump cannot reach its set temp within typically 15 min. or the temp falls 2 degrees It calls for backup heat (AUT HEAT). It also runs during defrost mode as well. This is the normal operating process.
