Frequently Asked Questions
My Tyler home's heat pump isn't switching from heat to cool properly. Could it be the reversing valve?
Yes, heat pump reversing valve issues are a common problem we see in the Tyler area due to our climate demands. This valve is crucial for changing the direction of refrigerant flow. If it's stuck or failing, your system won't heat or cool correctly. Our technicians are experts in diagnosing and repairing or replacing reversing valves to restore your system's proper function efficiently.
How can I tell if my home in Tyler has leaky ducts, and how do you fix it?
Signs of duct leakage in Tyler homes include uneven room temperatures, higher-than-normal energy bills, and excessive dust. Ductwork can settle or develop gaps over time, significantly reducing system efficiency. We perform a comprehensive inspection, often using specialized tools, to locate leaks. Our solution involves professional sealing and, if needed, repair or replacement of damaged sections to improve your comfort and lower your cooling and heating costs.
