I performed a single system heating maintenance on a 2016 straight electric system. I checked amps, capacitors, filter, electrical, cleanliness, and safeties. I discovered that the blower motor and evaporator coil need cleaning. Dirty components result in higher electric bills and unnecessarily added stress to the system. I observed that the pin connectors on the thermostat are corroding. To address the issue before failure, I provided an option to replace the thermostat. I reached out to Mr. Sharp and left a voicemail about these findings.
