Your heat pump should increase indoor comfort by blowing cool air during the warm months. Sometimes, it may do the opposite and start blowing warm air. Read on to learn why your heat pump in Estero, FL, is blowing hot air in cooling mode.

Refrigerant Leak

Your refrigerant operates in a closed loop. It moves from the evaporator coil to the condenser coils to facilitate the heat disposal process.

The fluid doesn’t get used up in the process. However, if there’s an opening in the cooling coils, fluid may start leaking, reducing its volume.

Refrigerant leaks reduce the system’s ability to extract heat from the air. Consequently, the air will make its way into your home while still warm. In addition to getting warm air in your home, you’ll hear hissing sounds when you have a refrigerant leak.

Trying to repair refrigerant leaks is dangerous because the fluid can harm people and the environment. A professional’s help can come in handy if you notice these leaks.

Leaky Ducts

If there are perforations in your ductwork, the openings allow the cooled air from your system to escape. Consequently, your home remains warm because the cooled air does not make it into your living space.

Leaky ducts make your system continue working, causing the energy bill to rise. The openings in these structures also allow dirty air to enter and circulate in your home, lowering the indoor air quality. During regular maintenance, a service technician can help spot these leaks and fix them before they cost you more comfort and cooling efficiency.

Dirty Air Filter

Your air filter prevents airborne contaminants such as pet dander, pollen and debris from circulating in your indoor air by trapping them. If you don’t replace this filter regularly, the pollutants accumulate on it, limiting the system’s ability to draw air from your home for cooling. Your home remains warm although the system is operating.
