Most Common Ac Repair Problems
Understanding some of the most common reasons your AC may not be working will help you feel more confident during the a/c repair process. From simple solutions, like recharging refrigerant, to larger challenges, like a failed AC capacitor, look for these symptoms to pinpoint the problem.
Signs of an AC refrigerant leak:
- Unexpected increase in cooling cost. Without the proper amount of refrigerant, the unit will work harder and longer to try to lower the temperature in your home.
- Air coming from vents isn’t cool. Without refrigerant, the HVAC loses its cooling capacity. You may hear the unit running and feel air being dispersed throughout the home, but it likely won’t be cool enough to make your space comfortable.
- Increased indoor humidity. A low refrigerant level won’t allow the indoor coil to get cold enough to remove moisture in the air, causing the humidity level in the home to rise.
- Outdoor unit makes a hissing sound. If your unit sounds like it’s releasing air or hissing, a leak within the system is likely.

- Water leakage and spilling: When algae, mold, or other debris blocks the trap or pipe, the condensate pan will fill with water and can eventually overflow. If left unaddressed, the water can damage your drywall, floors, or HVAC system.
- Mold growth: An odor of mildew or dampness may indicate mold is growing in the drain tube. Scheduling regular cleaning of the condensate drain will help avoid poor indoor air quality because of mold spores.
- Drain trap: A U-shape trap is connected to the condensate drain and allows water to flow out of the system. The trap can become clogged or dry out. Mold, mildew, and fungus can develop if water doesn’t flow properly, causing odors to back up into your home.
