HVAC Services Greer SC | Call D. O. Heating And Air

Short cycling is a common issue in our area and often points to a few specific problems. It could be an oversized AC unit that cools your home too quickly, a refrigerant leak, a dirty air filter restricting airflow, or a faulty thermostat. This constant cycling puts stress on your system, increases energy bills, and fails to dehumidify your home properly. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause and recommend the most effective repair to restore normal operation.

A failing capacitor, a frequent culprit in Greer's heat, often shows clear warning signs. You might hear a humming noise from your outdoor unit, notice the AC struggling to start (delayed or no cool air), or see the system shutting off unexpectedly. In some cases, the outdoor fan may not spin. These capacitors work hard in our summer heat and can weaken over time. If you notice these symptoms, it's best to call for service promptly to prevent a complete system breakdown on the hottest day.

Absolutely. Many of the common issues we see, like capacitor failure and conditions leading to short cycling, can be caught early or prevented with regular maintenance. Our seasonal tune-up includes inspecting and testing capacitors, checking refrigerant levels, cleaning coils, ensuring proper airflow, and calibrating thermostats.
