Expert Insights

Pro Tips: Thermostat Problems

Pro-level knowledge our network technicians use to diagnose and resolve this problem faster.

Test the Reversing Valve

On heat pumps, a stuck reversing valve prevents switching between heating and cooling. If your system only works in one mode, this is the likely cause.

Check Zone Dampers

If certain rooms are always too hot or cold, a stuck zone damper or failed control board is likely. A zoning specialist can diagnose it quickly.

Open All Vents and Returns

Closed supply or return vents increase system static pressure, overwork the blower, and reduce efficiency significantly. Ensure all are fully open.
