Heat Pump in Horizon, TX

Why Is My Heat Pump Blowing Warm Air in Cooling Mode in Horizon, TX?

May 23, 2024

Although the heat pump in your Horizon, TX home may seem to be working nonstop, your living space will remain warm if no cold air is coming from the vents. We’ll discuss some potential reasons why a heat pump might blow hot air in cooling mode.

Refrigerant Leaks

When the thermostat prompts the heat pump to start cooling your home, the refrigerant flows to the evaporator coil and absorbs heat from the indoor air. The hot refrigerant then goes to the outdoor condenser coil, where the heat in the fluid shifts to the surrounding environment.

When refrigerant leaks through damaged sections of the refrigerant lines, the amount left struggles to absorb and transport all the heat from your indoor air to the environment. Consequently, your house remains warm, and you’ll need to call for repair services to address the leakage.

A Dirty Outdoor Unit

The outdoor unit accommodates the condenser coil, where refrigerant disposes of heat in the summer. When dirt and debris contaminate the condenser coil, the refrigerant struggles to release heat to the surroundings.

As a result, your system takes longer to cool your house. You’ll need maintenance services from a technician who can clean all your heat pump’s components.

A Clogged Air Filter

All air from your living space must pass through the air filter before entering the heat pump. This ensures that all contaminants in the air remain on the filter.

When the filter catches too many pollutants, they block air from entering the system for cooling. Since most of your indoor air remains uncooled, your house remains warm. Replace your air filter regularly for improved airflow.

A Faulty Reversing Valve

In winter, the refrigerant moves heat from the outdoor coil to the indoor coil. When summer comes, the reversing valve makes the refrigerant move heat from the indoor coil to the outdoor coil. When this component becomes damaged, it doesn’t change the direction of refrigerant flow, so the fluid continues bringing in heat instead of eliminating it.

Don’t ignore a heat pump that doesn’t create the indoor environment you desire. Call our air conditioning experts at Dynamic Heating & Cooling, Refrigeration to have the underlying issues fixed. You can count on us to restore your system’s efficiency.
