Service built around the actual problem.
A thermostat problem can resemble an equipment failure, and a new thermostat must be compatible with the system it controls. ETERNA diagnoses low-voltage controls and installs appropriate replacements.
We verify wiring, equipment configuration, power, and system operation before blaming the thermostat or recommending an upgrade.

- Blank or unresponsive thermostat
