We test solenoids and refrigerant flow directly.
Not replacing the whole control on a guess.
You can't tell which failed just by watching the thermostat.
We don't treat heat pump calls as a summer specialty and go quiet the rest of the year.

What Lake Bluff heat pump owners ask most.
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.
Not just the mode it's currently running in.
Yes, defrost logic and staging vary meaningfully between manufacturers.
Climate affects wear patterns more than it affects overall lifespan.
Regular tune-ups extend that window meaningfully.
