Furnace Maintenance in Glendale, CA

Why proactive furnace maintenance matters in Glendale

Cooler winter nights and seasonal temperature swings in Glendale demand a reliable heating system. Routine furnace maintenance helps prevent mid‑season breakdowns, protects your investment, and keeps energy bills in check. Just as important, a well‑maintained system burns cleaner and circulates healthier air—core to our mission: healthy air at home for a healthy life.

What’s included in our furnace tune‑up

Our factory‑trained engineers deliver a careful, safety‑first inspection and service tailored to your system and space. Typical steps include:
• Visual and safety inspection (cabinet, wiring, controls, venting)
• Heat exchanger and burner assessment to help identify cracks, corrosion, or improper flame
• Ignition system check (spark/HSI) and flame sensor cleaning as needed
• Gas pressure, combustion air, and draft/venting check (for gas furnaces)
• Electrical component check (capacitors, relays, connections) for proper operation
• Blower motor and wheel inspection; verify airflow and balance
• Filter inspection/replacement (customer-supplied or available upon request)
• Thermostat calibration and cycle test
• Safety control verification and general system performance review
• Recommendations to improve efficiency, reliability, and indoor air quality
