Can I replace my thermostat myself without professional help?
You can replace a thermostat yourself, but professional installation helps avoid wiring errors and compatibility issues with zoned HVAC systems. Appleton Campbell installs and replaces programmable thermostats and can program and show you how to use them. Service is available in Ashburn, Haymarket, Bealeton, and nearby.
Quick checks before DIY:
- Turn off HVAC power at the breaker.
- Confirm your new thermostat matches your system and any zoning controls.
- Label each wire before removal.
- Mount, connect, and test each stage.
