Questions people ask before calling

Is it the thermostat or the system?

Check the batteries and settings first. If the screen is lit but nothing runs, it could be a wiring or system issue — a tech can sort it out.

Should I upgrade to a smart thermostat?

Smart thermostats pay off if your schedule varies. Have the tech confirm it's compatible with your system first.

How much does thermostat replacement cost?

The thermostat itself is the small part; most of the cost is the service visit. Some shops waive the visit fee with the install.

My thermostat screen is blank. Now what?

Try fresh batteries and check the breaker. If it stays blank, the thermostat or its wiring may need professional attention.
