What to expect.
We review the symptoms, thermostat operation, and equipment condition.
The inspection follows the issue and may include ignition, safety controls, electrical components, venting, and airflow.
We explain the findings and discuss repair options before work proceeds.
Before your appointment.
Write down thermostat messages and keep the equipment area accessible. If you smell gas, leave the building and call your gas utility or 911 from a safe location. If a carbon monoxide alarm sounds, leave and call 911.
What affects the cost?
The failed component, furnace type, access, diagnostic needs, and parts availability determine the repair scope. The diagnostic visit is $89, waived with a completed repair. We will discuss the recommended work before you authorize it.
