Uneven heating from a thermostat malfunction is a frequent complaint locally. This can be caused by incorrect calibration, wiring issues, or the thermostat's location sensing drafts or sunlight.

Our thorough diagnostic service is designed to pinpoint the root cause of issues like ignition failures or thermostat problems. It includes a complete system inspection, safety checks, electrical testing, and performance analysis. We explain our findings clearly before any work begins, providing you with repair options and transparent pricing.
