Common AC Issues: Blowing Warm Air

Feeling a blast of warm air instead of the usual cool breeze is one of the most common AC issues that homeowners in Central New York face. Before you call in for a Castle Creek AC repair, however, it’s important to understand that there are many potential underlying problems that can cause your AC to blow warm air, including the following:

Low Refrigerant Levels

Your AC relies on refrigerant to achieve its cooling capabilities. It cycles the fluid between its condenser and evaporator to remove heat from your home. Low refrigerant levels impede that ability, eventually preventing cooling altogether. Your AC may have low refrigerant levels due to a slow leak over time or more serious damage to its coils or lines.

Clogged Air Filters

Refrigerant may be what cools the air, but your AC needs to be able to suck in air and pass it over its evaporator coils to receive that cooling. Your unit draws in air through an air filter to prevent dust and debris from reaching these coils, but dust eventually builds up and blocks the filter regardless. If you haven’t changed your air filter in three months or longer, then it could be clogged, preventing efficient operation.

Dirty Coils

Your AC’s evaporator and condenser coils have a high surface area to allow for rapid heat transfer. But when they get mucked up with any kind of dirt or residue, they can’t transfer heat effectively. Annual cleaning from a professional is an excellent way to maintain efficiency.

Thermostat Settings

Your thermostat also plays a major role in your AC’s operation. It could be set to an improper setting, such as “heat” or “fan,” though there could be some fault with its internal system or wiring as well.

Electrical Issues

Your AC contains a variety of important electrical components. If any of these face issues, it can result in warm air being blown out. In many cases, safety components will go first, affecting the unit’s operation. Luckily, these are typically straightforward repairs.
