Lennox Furnace Maintenance in Pasadena, CA

Why Annual Maintenance Matters

Regular maintenance keeps your Lennox furnace operating safely and efficiently during Pasadena’s cool months. A tuned system uses less energy, distributes heat more evenly, and reduces the chance of inconvenient breakdowns. Maintenance also helps protect heat‑exchanger integrity and manage carbon‑monoxide risk, while supporting cleaner indoor air—central to our mission: healthy air at home for a healthy life.

What Our Lennox Furnace Service Includes

We follow a rigorous, model‑specific process for Lennox gas furnaces:

• Complete safety inspection, including ignition sequence, flame behavior, and CO checks where applicable.
• Combustion analysis and draft verification to help ensure proper burn and venting.
• Heat‑exchanger and burner assessment (non‑invasive visual and accessible components) with targeted cleaning.
• Blower assembly cleaning, motor amperage check, and capacitor testing for reliable airflow.
• Air filter replacement or cleaning and static‑pressure review to support duct performance and IAQ.
• Thermostat and control calibration to maintain accurate temperature and smart operation.
• Gas‑pressure and manifold adjustments per Lennox specifications where needed.
• Inducer, pressure switch, and flame sensor inspection/cleaning for consistent starts.
• Condensate trap and drain attention on high‑efficiency (condensing) Lennox models.
