Heating repair: frequently asked questions

Cost depends on the cause, an igniter or thermostat issue costs less than a heat exchanger or blower motor failure. AIRSOURCE diagnoses first and gives you an upfront price before any repair begins.

Common causes include a faulty igniter or pilot light, a tripped limit switch, thermostat problems, or airflow issues from a dirty filter. AIRSOURCE diagnoses the specific cause on-site rather than guessing.

It depends on the system's age and the cost of the repair relative to a new system. AIRSOURCE will give you an honest recommendation either way, see heating installation → if replacement makes more sense.
