Common HVAC Emergencies

Frozen Condenser Coil

One of the most common HVAC emergencies is a frozen condenser coil. This occurs when there is a problem with the airflow or refrigerant levels in the system. When the condenser coil freezes, it can cause the entire HVAC system to malfunction and stop providing heating or cooling to your home or office. If you notice ice or frost on the condenser coil, it is important to address the issue immediately.

Faulty Compressor

Another common HVAC emergency is a faulty compressor. The compressor is responsible for circulating the refrigerant and is essential for the proper operation of the system. A faulty compressor can result in a complete system failure or reduced heating and cooling capacity. Signs of a faulty compressor include strange noises, warm air blowing from the vents, or a complete loss of heating or cooling.

Leaking Refrigerant

A leaking refrigerant is a serious HVAC emergency that can have both health and environmental consequences. Refrigerant leaks can occur due to damaged or corroded pipes, loose fittings, or worn-out connections. If you notice a strong and unusual smell coming from your HVAC system, or if you spot any signs of refrigerant leakage such as oily spots or hissing sounds, it is crucial to address the issue immediately.

Clogged Air Filter

A clogged air filter can also lead to HVAC emergencies. The air filter in your HVAC system is responsible for trapping dust, dirt, and other particles to improve indoor air quality. However, if the air filter becomes clogged, it can restrict airflow and cause the system to overheat. This can lead to reduced heating or cooling efficiency and potential damage to the system if left unaddressed. Regularly checking and changing the air filter is essential to prevent this type of emergency.

Signs of HVAC Emergency
