This pattern shouldn't be ignored — some of the underlying causes carry genuine carbon monoxide risk. Ignoring furnace won't ignite or keeps shutting off rarely makes the underlying issue cheaper to fix later.

We service central air, packaged units, and ductless mini-splits, and we size every new installation with an actual load calculation rather than matching the old unit's tonnage on a guess.

Heat pump-specific diagnostics cover the reversing valve and defrost cycle, components that a generalist unfamiliar with heat pumps can easily misdiagnose. Techs handling heating & furnace services carry the specific parts and tools this job calls for, not a generic kit.
