FAQ
Thermostat Installation — Frequently Asked Questions
Yes — that's a common upgrade. We swap it for a clean digital or programmable model and dispose of the old one properly.
Only the right one will. Heat pumps and dual-fuel systems need a compatible thermostat to control backup heat — we make sure it matches.
Not necessarily. A good programmable model works great for many homes; see our smart thermostat page if you want app control.
Maybe, but it can also be wiring or a tripped safety. We'll find the real cause before replacing it.
Yes — thermostat setup is part of any install, or we can upgrade it on its own.
