4 Reasons Your Heat Pump is Blowing Warm Air in Cooling Mode

August 15, 2023

Living in Lorida, FL, means relying on your heat pump to keep your home comfortable year-round. However, encountering warm air blowing from your system when it’s supposed to be in cooling mode can be frustrating and uncomfortable, especially during hot and humid summers. This article explores common causes of a heat pump blowing warm air in cooling mode.

Incorrect Thermostat Settings

Before diving into more complex issues, double-check your thermostat settings. Ensure it’s set to cooling mode and the temperature is lower than the current room temperature.

Refrigerant Leak

You may have leak if your heat pump is blowing warm air in cooling mode. This is most likely if the system sits below a floor and ceiling or if condensation has collected on the heat pump’s exterior. The first step to identifying a refrigerant leak will be looking for white frosty condensation outside your heat pump. You should hire a professional to find and fix the refrigerant leak since this substance can be hazardous to your health and the environment.

Duct Leak

You may have a duct leak if your heat pump blows warm air in cooling mode. The first step to identifying a duct leak will be looking for wet spots on the floor or ceiling or white frost on the floor surface.

Clogged Air Filter

A clogged air filter can reduce the amount of air entering your heat pump and cause it to work harder to cool your home. This will overload the system and cause it to blow warm air in the cooling model. Ideally, you should change your heat pump’s filter every 30-90 days to prevent clogs.

Experiencing warm air blowing from your heat pump in cooling mode can be frustrating during the hot summer months.
