Heat pumps, like all mechanical appliances, can be finicky at times. You may have kept up with a strict schedule of maintenance and still find yourself without heat in the dead of winter or lacking cool air in the summer.
Regular maintenance includes things like:
Check furnace filter / offer replacement
Condensing coil and fin cleaning
Lubricate all moving parts
A comprehensive, 22-point maintenance checklist
The great thing about keeping up with your regular maintenance is if there’s ever a unique problem requiring repairs, you’ll receive a discount on regular and emergency labour rates.
