constantly running heat pump in Horizon, TX

Why Isn’t My Heat Pump Shutting Off in Horizon, TX?

April 24, 2025

Cooling your home in Horizon, TX, this spring is easier when you own a heat pump. If your heat pump operates nonstop and cycles without end, professional services may be necessary. Learn about some issues that can contribute to a constantly running heat pump and what you can do about them.

Thermostat Settings

If your heat pump cycles long beyond the normal time, go check your thermostat. Make sure the heat pump is set to the proper mode, and the temperature is at a reasonable setting.

Dirty Air Filter

Air filters trap contaminants that enter the HVAC system, and if you don’t change or clean them, they can clog. If your air filter is dirty, the heat pump may struggle to produce enough cold air and push it through the ducts. Change your filter at least once every three months to prevent a dirty, stressed system.

Refrigerant Leak

Your heat pump uses refrigerant to assist in making cold air for your home. Without refrigerant, the heat pump may struggle to reach the desired temperature and continue running.

Undersized Heat Pump

If your heat pump cannot create enough cold air to bring your entire home to the desired temperature, it may continue to cycle. When choosing a heat pump, ensure the appliance is the right size for your home. Additions and renovations can change how well your heat pump cools.

Dirty Coils or Interior of System

Excessive dust and debris buildup inside your heat pump can add stress to the system. This stress may cause your coils to freeze, preventing the system from making cold air. The heat pump may then cycle without end as it tries to reach the temperature setting.

If your heat pump runs without stopping, you may need professional repairs. Call Dynamic Heating & Cooling, Refrigeration today to schedule the HVAC repairs you need to be comfortable in your Horizon home.
