Heat Pump Repair FAQ
Is it normal for my heat pump to have frost on it?
A light coating of frost is normal in winter, but heavy ice build-up indicates a failure in the defrost cycle or low refrigerant.
How long does a heat pump diagnostic take?
Typically 45-60 minutes to thoroughly test the electrical, mechanical, and refrigerant components.
Why is my heat pump making a loud 'whoosh' sound?
This is usually the sound of the system entering or exiting the defrost cycle—completely normal!
Do you service hybrid or dual-fuel systems?
Yes, we are experts in systems that combine a heat pump with a gas furnace backup.
How often should a heat pump be serviced?
Because they run year-round, heat pumps should be tuned up twice a year.
Can a heat pump heat my home when it's sub-zero?
Modern cold-climate units can, but many older units rely on auxiliary 'emergency' heat below 20-30 degrees.
What causes a heat pump to stay in 'Emergency Heat' mode?
This usually happens when the outdoor unit isn't running properly or the thermostat is set manually to EM HEAT.
Should I repair or replace my 15-year-old heat pump?
If repair costs are high, we usually recommend a replacement quote for units over 12-15 years old.
