Can I replace my thermostat myself without professional help?

You can replace a basic like-for-like thermostat yourself, but professional installation is recommended for smart thermostats, heat pumps, mini-splits, or zoning. Our in-house technicians handle setup and thermostat calibration, and we integrate controls with your HVAC. To access Mass Save offers, some instant rebates over $100 and no-cost thermostats require installation by our Home Energy Auditor, subject to eligibility.

Quick checks:

• Shut off HVAC power.
• Confirm system type and label wires.
• Photograph existing connections.
• Verify smart thermostat compatibility before purchase.

"After completion the team verified that everything was working perfectly and explained how the heat pump and furnace operated and how to control everything using the smart thermostats." — Wes M.
