You expect an air conditioner to keep your property cool and comfortable. However, the vents may currently deliver nothing but warm air. This situation can signify an issue somewhere in the system, many of which you can prevent with proper AC maintenance. Here are three common causes of warm air to help determine the source of the problem.
Why Does Your AC Blow Warm Air?
1. Clogged Filter
The air filter traps the particulates that can circulate throughout the property, like mold spores, dust mites, dirt, and pet dander. Over time, the part becomes clogged with these contaminants, preventing it from doing its job efficiently.
Because the air can’t pass through the filter properly, the unit needs to work even harder to provide cool air. With this level of restricted airflow, you may feel only warm air instead of the refreshing breeze you expect. As part of your general AC maintenance routine, replace the filter at least once every two to three months or more often if you have a pet.
2. Obstructed Unit
The outdoor unit, which houses the condenser coil, compressor, and fan, disperses the heat absorbed inside the home. Because of its location, overgrown grass, brush, leaves, and dirt can obstruct it.
An accumulation of landscaping debris will block the parts and prevent them from working properly, causing warm air to circulate in your home. Clean this unit before turning on the system to ensure it isn’t compromised.
3. Refrigerant Leak
Refrigerant is the substance that helps transform heat into cool air. If the unit lacks this fluid, it won’t work efficiently. This issue is among the most common reasons for warm air.
Low liquid levels can only occur if there’s a leak in the lines. The substance doesn’t run out on its own, as none of it enters or exits through the closed system. Before calling an HVAC technician to solve the problem and refill the refrigerant, determine if there’s a leak by checking if the evaporator coils have frost.
