Heater Repair

No heat? Odd noises? We’ll run a diagnostic, repair on the spot when parts are on the truck, and if a special part is needed, we’ll order from vetted suppliers and return promptly. Every repair includes a minimum 6-month warranty; extended coverage for VoltyxCare+ members.

Multi-point diagnostic

• Safety & CO check
• Power/controls (breaker, 24-V, thermostat codes)
• Airflow (filter fit, blower, ducts)
• Heat source (gas valve/ignition or electric heat strips; for ducted heat pumps—outdoor unit, reversing valve, defrost)
• Venting & drains (condensing models)
• Test run (temperature rise, amps, final tune)

Common causes

• Clogged or wrong-size filter → limit trips
• Worn igniter or dirty flame sensor
• Faulty pressure/limit switch
• Tired inducer/blower motor
• Board/capacitor/relay faults
• Heat pump defrost issues
• Blocked drain or poor draft

What to expect

Focused diagnostic → upfront repair options → on-site repair when possible → safety checks → written warranty.
