Heat Pump Repair in Alexandria, IN

Alexandria's climate presents a full range of operating conditions for heat pumps. Summers bring sustained humidity with highs in the 85 to 95 degree range, while winters regularly push December through February into the teens and single digits. Most heat pump systems in this area operate as part of a dual-fuel configuration, where the heat pump handles moderate temperatures and an existing gas furnace supplied by CenterPoint Energy (Vectren North) takes over when outdoor temperatures drop below the heat pump's efficient operating range. That handoff point, called the balance point, is one of the things we verify during a repair call.

Heat pump problems in this climate tend to show up in one of two ways: summer cooling issues that look exactly like a conventional AC failure, or winter heating issues where the system runs but produces only slightly warm air, switches to emergency heat, or trips on a fault. We diagnose both directions of the refrigerant circuit.

Heat pump repairs require diagnosing the reversing valve, defrost board, refrigerant circuit, compressor, and the auxiliary heat backup in a single service call. We carry test equipment for the full system, not just the cooling side:

• Reversing valve failures that cause the system to stay in one mode regardless of thermostat demand, a common failure point in older heat pumps.
• Defrost board and defrost sensor failures that prevent the outdoor coil from clearing ice in cold weather, leading to reduced efficiency and eventual lockout.
• Refrigerant leaks and low-charge conditions that reduce capacity in both heating and cooling modes.
• Capacitor and contactor failures in the outdoor unit that prevent the compressor or outdoor fan from starting.
• Dual-fuel control board issues where the gas furnace backup is not activating correctly when outdoor temperatures fall below the balance point.

Heat pumps have a different repair-versus-replace calculus than conventional AC units because they carry heating season load as well. A failed reversing valve on a unit with low overall remaining service life is usually a replacement trigger rather than a repair. A capacitor failure or sensor problem on a mechanically sound unit is typically worth repairing. We give you the actual equipment condition assessment alongside the repair quote so the decision is yours to make with real information.

If replacement makes sense, Indiana Michigan Power (AEP) offers energy-savings rebates for qualifying heat pump installations, and federal HOMES programs may apply depending on household income. Verify current terms and eligibility before committing to a purchase.

My heat pump is covered in ice. Should I be worried?

Some frost on the outdoor coil during cold weather is normal, and a properly functioning defrost cycle will clear it periodically. A coil that is frozen solid and stays that way, or one that never appears to defrost, indicates a defrost board or sensor failure. Turn the system to emergency heat and call for service rather than letting a compressor work against a blocked coil.

Why does my heat pump blow cool air in heating mode?

Heat pumps produce air that feels cooler than what a gas furnace produces, which is normal, but air that is genuinely cold coming from the vents usually means the reversing valve is stuck in cooling mode, refrigerant is low, or the outdoor unit is not functioning. Do not confuse this with the brief cool air that blows before the system warms up from a standing start.

At what outdoor temperature does the gas furnace backup take over in a dual-fuel setup?

The balance point is programmed into the thermostat or control system and is typically set between 25 and 35 degrees Fahrenheit for Madison County's climate. Below that point, the gas furnace is more cost-effective than the heat pump. If your system is not switching over correctly, the balance point setting and the dual-fuel control board are the first things we check.

Can you service a heat pump installed by a different contractor?

Yes. We service all major residential brands regardless of who installed them. We do ask that you have the original installation documentation available if possible, as the balance point setting and auxiliary heat configuration are sometimes set non-standardly by the original installer.
