HVAC Services Harrison OH | Call Dodds Heating & Cooling

In Harrison, common signs include your system blowing cool air when set to heat (or warm air when set to cool), getting stuck in one mode, or making a distinct hissing noise. This valve is crucial for switching between heating and cooling. If you notice these issues, especially during our seasonal shifts, it's best to call for a professional diagnosis to prevent further damage and discomfort.

Given the pollen, dirt, and debris common in our area, we recommend a visual check each spring and a professional cleaning at least once a year. Dirty coils force your system to work much harder, leading to higher energy bills and potential breakdowns during our hottest days. Regular cleaning is a simple, proactive step to maintain efficiency and extend the life of your Harrison home's HVAC system.

Absolutely. When the condenser coils outside are clogged with dirt and debris, they can't release heat properly. This causes a pressure imbalance in the system, often leading to the evaporator coil inside freezing over, even in warm weather. If you see ice on your indoor unit, a dirty outdoor coil could be the culprit. Our technicians can safely thaw the system, clean the coils thoroughly, and restore proper operation.
