FAQs: What You Need to Know

How does my AC system work?

Air conditioning systems move warm air from inside your home over an evaporator coil, which contains a liquid refrigerant. As the refrigerant absorbs heat from the air, it warms up and evaporates (while remaining inside the coil). The now-cool air is blown back into your home, typically through ductwork. The refrigerant, now a warm gas, travels to the condenser, which is located in a unit outside your home. The condenser extracts heat from the refrigerant and releases it to the outside air; meanwhile, the refrigerant cools and returns to liquid form. It’s then circulated back to the evaporator coil, where it starts the process again. This cycle repeats throughout the day so your AC system can provide cool, refreshing conditioned air.

What are the common causes of AC system failures?

The top three causes for AC system failures are electrical issues, such as weak connections or bad circuits, motor failures, and a buildup of dirt that restricts airflow.

Why does my AC system smell?

That foul smell coming from your AC system might be from a number of things. If you are smelling damp, mildewy aromas coming from your AC, it may be due to excess moisture in the system from a clogged filter. If you are smelling a burnt smell, your system may have bad electrical contact points in the compressor that will need replacing right away.

How do I clean my AC system?

Make sure that your filter, condenser coil, and blower are free of dirt or dust buildup. This way, air can continue to flow freely through the system.
