Common questions before a Heat Pump Repair visit.
Nine times out of ten this points to a reversing valve stuck in the wrong position, though we still check refrigerant charge since it can mimic the same symptom.
A thin layer of frost comes and goes normally; ice that just sits there and builds up means the defrost logic isn't doing its job.
The signal isn't reaching the strips the way it should.
A heat pump tune-up covers ground a standard AC visit never touches, namely the defrost cycle and the reversing valve.
Year-round, both heating and cooling mode failures covered.
We verify in both modes since the system runs two ways.
Yes, defrost logic and staging vary meaningfully between manufacturers.
Not inherently, though the auxiliary heat strips see more use in harsher climates and are worth checking during maintenance.
Regular tune-ups extend that window meaningfully.
