Signs Your AC Needs Repair

It can be difficult to know when an air conditioner needs to be repaired, but there are some classic telltale signs.

Not Blowing Cold Air

One of the most noticeable signs that your HVAC unit requires repair is the absence of cool air from the vents. This problem can stem from various issues.

Low Airflow

Another warning sign is weakened airflow from the vents, which should usually be powerful. If you notice this, contact our team immediately. In some cases, simply replacing a dirty air filter can solve the problem.

Unusually Moist Areas

Moisture forming around your AC unit may indicate a refrigerant problem. Our skilled technicians can quickly locate and repair any refrigerant leaks.

Other classic signs include knocking sounds and rapid cycling. The most important thing to remember, however, is that any type of unusual behavior can indicate a problem. Don’t put off calling for help. Avoiding simple repairs can lead to larger, more expensive issues.
