HVAC Stopped Working After a New Thermostat in Morrisville
Morrisville · August 2026 · Travis & Dexter · From our service records
What the customer reported
A Morrisville property contact reported that maintenance replaced an old thermostat and the HVAC system stopped working afterward. Maintenance suspected the compressor was not turning on and was unsure if the new thermostat was the cause or if there was another underlying issue, with a resident moving in the next day.
What we found and did
Travis and Dexter visited the home for a diagnostic. Travis programmed the thermostat to the specified temperature settings and operating schedule. All programmed setpoints, time periods, and system modes were reviewed to make sure they were entered correctly. The thermostat was then tested for temperature adjustment and system response.
Result
The programming was verified to be functioning as intended, and the thermostat was left in normal operating mode.
