Heat Pump Repair in McCordsville, IN

When McCordsville's subdivisions went up, many were built with electric heat pumps rather than a straight gas furnace, and dual-fuel pairings are common too. A heat pump is a different machine, it both heats and cools through one refrigerant circuit, so it fails in ways a furnace never does. This page is the heat pump repair lane specifically. The faults below are heat-pump faults, not furnace faults, and we diagnose them as such.

• A reversing valve that sticks, so the system blows cold in heat mode or warm in cool mode.
• Defrost-cycle faults that let the outdoor coil ice over in cold weather.
• Refrigerant leaks that cut both heating and cooling capacity.
• Failed defrost boards, sensors, and contactors specific to heat pump controls.
• Auxiliary and emergency heat strips that are not engaging when the heat pump needs backup.

A frozen outdoor unit in a McCordsville January is normal for a few minutes during a defrost cycle, but a coil that stays iced over points to a defrost-control or refrigerant problem. We read the refrigerant pressures, test the reversing valve and defrost board, and check that the auxiliary heat is backing up the system correctly on the coldest nights. That is different work from a gas furnace call.

A younger heat pump with a single failed component is worth repairing. One that is low on refrigerant again and again is telling you something.

If yours is aging out and you want to plan a replacement, see heat pump installation in McCordsville for cold-climate and dual-fuel options.

My heat pump is blowing cold air in heat mode. Why?

Often a stuck reversing valve or a defrost-cycle fault. Both are heat-pump-specific and we test for them directly rather than treating it like a furnace.

The outdoor unit iced over. Is that a problem?

A short defrost is normal in cold weather. A coil that stays encased in ice points to a defrost-control or refrigerant issue, which we diagnose.

Why is my electric bill spiking in winter?

Often the heat pump is leaning on auxiliary heat strips because the compressor side is underperforming. We find why the heat pump is not carrying its share.

Do you service dual-fuel systems?

Yes. We check that the heat pump and the gas furnace hand off correctly so the system uses the most efficient source for the conditions.
