Heat Pump Repair in Plainfield, Indiana

Heat pumps show up most in Plainfield's newest construction, where all-electric and dual-fuel systems are increasingly the default. A heat pump runs year-round, heating in winter and cooling in summer, so a fault can leave you without either. Because it works in both directions, it has parts a straight furnace or AC does not, and diagnosing it takes specific knowledge.

Duke Energy Indiana powers these systems, and a heat pump stuck in resistance-heat mode quietly runs your winter bill up. We find why it stopped switching over instead of leaving it on expensive backup heat.

Heat-pump-specific failures we repair

• Reversing valve stuck between heating and cooling modes
• Defrost control failures that ice the outdoor coil in winter
• Refrigerant leaks and charge problems unique to heat pumps
• Auxiliary or emergency heat strips running when they should not
• Outdoor unit not running in single-digit cold

In single-digit Plainfield cold, a healthy heat pump cycles through defrost to shed frost from the outdoor coil. When the defrost control fails, the coil ices over and heating output collapses. We test the defrost sequence, the reversing valve, and the backup heat staging so the system runs efficiently instead of leaning on costly strip heat.

Why is my heat pump blowing cold air in winter?

It may be stuck in cooling mode from a faulty reversing valve, or running a defrost cycle, or low on refrigerant. These are heat-pump-specific faults we diagnose on site.

My outdoor unit iced over. Is that normal?

Light frost that clears during defrost is normal. A fully iced coil that stays frozen points to a defrost control or refrigerant problem, and we will fix it.

Why is my electric bill so high this winter?

Often the heat pump has stopped switching properly and is running on auxiliary strip heat. We find and correct the cause so it stops leaning on expensive backup heat.

Do you repair both all-electric and dual-fuel heat pumps?

Yes. Both are common in Plainfield's newer subdivisions, and we service each.

Can you repair a heat pump same day?

We prioritize no-heat and no-cool calls. Call (317) 436-3846 and we will dispatch from the local area as quickly as possible.
