Can I replace my thermostat myself without professional help?

You can replace a basic thermostat yourself, but we recommend professional installation for smart models, heat pump systems, or when your furnace or AC has irregular on/off behavior. Incorrect wiring can cause short-cycling or no heat/cool. Our technicians can install on the spot, verify compatibility, and set up the app and programming. We also troubleshoot gas furnace thermostat faults and provide maintenance plans to keep settings optimized in Columbia and nearby cities like Lexington and Irmo.

Quick checks:

• Confirm compatibility with your system.
• Turn off power and label each wire.
• Test heating and cooling after install.
