Pasadena Residential Furnace Tune‑Up

What’s Included in a #1 AC Guys Furnace Tune-Up

Our residential furnace tune-up is designed to maximize safety, performance, and longevity while maintaining healthy indoor air. We follow an engineering-driven checklist that addresses the details other services often miss.

• Thermostat calibration and control verification
• Safety control testing (limit switch, rollout, ignition lockout)
• Combustion and gas pressure measurements for efficient, stable flame
• Burner, flame sensor, and ignition system cleaning
• Heat exchanger inspection for cracks or corrosion
• Blower motor amperage check, wheel cleaning, and belt inspection (if applicable)
• Electrical tightening, wiring assessment, and component testing
• Filter replacement or cleaning and airflow optimization
• Vent and flue inspection to support safe exhaust
• Carbon monoxide checks and recommendations for monitoring
• Ductwork condition review for leaks, balance, and static pressure

By aligning these steps with manufacturer best practices, we help your furnace operate smoothly and safely throughout Pasadena’s heating season.

How Often Should I Schedule a Tune-Up in Pasadena?

For most Pasadena homes, an annual furnace tune-up before the cooler months is ideal. If your home has high usage, recent renovations, or indoor air quality concerns, consider a mid-season check as well. Annual maintenance helps stabilize efficiency, extends system life, and reduces surprise repairs.

Healthier Air, Safer Heat

We believe clean, healthy air is essential. During your tune-up, we look at filtration, duct cleanliness, ventilation, and combustion safety. We’ll discuss options to reduce particles and allergens, improve ventilation rates, and support safer combustion. Better IAQ can mean fewer odors, less dust, and a more comfortable home—especially valuable for families with children, older adults, or anyone with sensitivities.

Our Process

1) Listen and inspect: We start by understanding comfort issues, hot/cold spots, or any unusual sounds.
2) Measure and verify: We collect readings on gas pressure, temperature rise, static pressure, and motor amperage.
3) Clean and optimize: We clean critical components, calibrate controls, and adjust for smooth starts and steady heat.
4) Report and advise: You’ll receive clear findings and practical recommendations to prevent future issues.

Service Area

We proudly serve Pasadena neighborhoods and the surrounding San Gabriel Valley, as well as Los Angeles County and nearby regions including Orange County, Ventura County, and Western Riverside County. Whether you’re in a historic Pasadena bungalow or a modern hillside home, we tailor maintenance to your system and space.
