Licensed HVAC Repair in Delaware, OH 43015 - Done Right HVAC

In Delaware's variable climate, a faulty reversing valve is a common issue. Key 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. If you notice these symptoms, it's best to call for a professional diagnosis. Our technicians can test the valve and perform the precise repair to restore your home's comfort efficiently.

For most Delaware homes, we recommend checking your HVAC air filter every month and replacing it at least every 90 days. If you have pets, allergies, or significant dust, you may need to change it monthly. A clogged filter is a primary cause of restricted airflow, which forces your system to work harder, increases energy bills, and can lead to premature breakdowns. Regular changes are a simple, effective way to protect your investment.

Absolutely. Restricted airflow from a clogged filter creates a chain reaction of problems. It causes the heat pump's coil to freeze in cooling mode or overheat in heating mode, triggering safety shut-offs and mimicking other failures. This added strain can also contribute to issues like reversing valve stress. Ensuring clean filters is a critical first step in maintenance that helps prevent unnecessary repairs and keeps your system running smoothly through Ohio's seasons.
