FAQ

What is a defrost cycle and why is it important?

A defrost cycle temporarily reverses your heat pump to melt ice on outdoor coils, preventing frost buildup that reduces heating efficiency.

How do I know if my defrost cycle is failing?

Signs include heavy ice on the outdoor coil, reduced heating output, long run times, and unusual noises during defrost attempts.

Can I delay defrost cycle repair?

Delaying can lead to compressor strain, higher energy bills, and eventual system lockout. Prompt repair avoids costly breakdowns.

How long does a defrost cycle repair take?

Most repairs complete within 2–4 hours, depending on parts needed and system accessibility.

Will repairing the defrost cycle improve heating performance?

Yes. Proper defrost function restores full heat exchange capacity, reducing run times and energy consumption.

Do you recharge refrigerant as part of defrost repair?

If low refrigerant contributes to ice buildup, we locate leaks, repair lines, and recharge to the exact manufacturer-specified level.

How often should defrost components be inspected?

We recommend annual defrost sensor and control checks as part of your fall heat pump maintenance.

Can extreme weather cause defrost issues?

Prolonged sub-freezing temperatures and wind-driven snow can exacerbate defrost failures; regular maintenance helps prevent these issues.
