Heat Pump Repair & Installation in Houston, TX

Houston's climate is well-suited for heat pump performance. Long cooling seasons, mild winters, and temperatures that only occasionally drop below freezing put the Greater Houston area squarely in the operating range where heat pumps deliver their best efficiency. A heat pump handles both heating and cooling from a single system, which makes it a practical and increasingly popular choice for homeowners throughout Harris County, Fort Bend County, Montgomery County, and Austin County.

At Multipoint AC & Heating, we provide heat pump repair, installation, and maintenance throughout Greater Houston.

HEAT PUMP REPAIR

Heat pumps share components with conventional AC systems but have additional parts — particularly the reversing valve that switches between heating and cooling modes — that require specific diagnostic experience to service correctly. Common heat pump problems we repair throughout Houston include:

System blowing cold air in heating mode — typically points to a reversing valve problem, low refrigerant, or an outdoor unit issue rather than a normal defrost cycle if it's happening consistently.

Reversing valve failure — when the valve sticks or fails, the system locks in one mode regardless of what the thermostat calls for.

Ice buildup on the outdoor unit — heavy accumulation that doesn't clear during the defrost cycle usually indicates a refrigerant problem, a failed defrost board, or restricted airflow.

System not reaching the set temperature — most commonly caused by low refrigerant, a dirty air handler, or a capacity issue. In Houston's humidity, dehumidification problems often appear before temperature control problems do.

Refrigerant leaks — affects performance in both heating and cooling modes. We locate the source, repair it, and restore the charge before returning the system to service.

HEAT PUMP INSTALLATION

We help Houston-area homeowners evaluate whether a heat pump is the right fit based on existing ductwork, home size, heating and cooling load, and energy goals. When it makes sense, we handle the complete installation — load calculation, equipment selection, indoor and outdoor unit installation, refrigerant charging, and full system commissioning.

For homeowners in upper Montgomery County communities like Willis, Conroe, and New Caney where below-freezing temperatures are somewhat more frequent than in Fort Bend or inner Harris County, cold-climate heat pump specifications are worth discussing during equipment selection.

DUCTLESS HEAT PUMP MINI SPLITS

For spaces the central system doesn't reach — garage conversions, room additions, detached guest structures, or workshops — ductless mini split systems with heat pump functionality provide both heating and cooling without existing ductwork. We install single-zone and multi-zone systems throughout Greater Houston.

HEAT PUMP MAINTENANCE

Annual maintenance keeps heat pumps running efficiently and catches developing problems before they become failures. During a heat pump maintenance visit we clean the coils, check refrigerant charge, test the reversing valve and defrost system, inspect electrical components, clear the condensate drain, check blower operation, and verify thermostat and control function.

In Houston's humidity environment, coil condition and condensate management receive particular attention. Biological growth on the evaporator coil and algae in the condensate drain develop faster here than in drier climates and affect both performance and indoor air quality if left unaddressed.

IS A HEAT PUMP RIGHT FOR YOUR HOME

A heat pump is worth serious consideration if you are replacing an aging system and want one unit that handles both heating and cooling, if your home lacks a gas line and currently uses electric resistance heating, if you are adding climate control to a space without ductwork, or if long-term energy efficiency is a priority. A conventional split system with a gas furnace may still be the better fit for larger homes with significant heating loads or homes in the upper Montgomery County corridor where winters are more demanding. We give you a straightforward comparison of both options based on your specific home rather than defaulting to one answer for everyone.
