When your heater runs smoothly, you enjoy lower energy costs, steadier comfort, cleaner indoor air, and longer equipment life. #1 AC Guys delivers residential furnace maintenance with a level of precision that comes from four generations of engineering and 80+ years in the field. We specialize in both straightforward and complex homes, including large properties, zoned systems, and high-efficiency equipment.

What Our Furnace Maintenance Includes

• Safety-first combustion checks and carbon monoxide screening
• Heat exchanger, burners, igniter, and flame sensor inspection and cleaning
• Blower assembly cleaning and motor amperage verification
• Airflow and static pressure checks to protect efficiency and heat exchanger
• Filter evaluation and recommendations for IAQ and performance
• Thermostat calibration and control testing
• Electrical connections tightened, capacitors and relays tested
• Flue and venting evaluation for code and safety
• Ductwork condition review and leak reduction recommendations

Every step is documented so you know what we checked, what we improved, and how your system is performing.

Healthy Air at Home

Our mission is healthy air in your home for a healthier life. During maintenance, we identify dust and particulate sources, recommend filter upgrades where appropriate, and offer add-ons like deep blower cleaning or IAQ enhancements. Better airflow and cleaner components mean less dust, fewer odors, and a more comfortable home.

Factory-Trained Knowledge You Can Trust

Our team has completed training at manufacturer facilities for Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background helps us maintain modern variable-speed blowers, smart controls, and high-efficiency equipment with confidence, while ensuring your furnace operates safely and reliably throughout Los Angeles winters.

Why Maintenance Pays for Itself

• Efficiency: Reduced energy use by keeping burners clean and airflow correct
• Reliability: Catch small issues before they become emergency breakdowns
• Longevity: Protect the heat exchanger and motors to extend equipment life
• Comfort: Eliminate hot and cold spots with balanced airflow
• Safety: Proactive checks for CO and proper venting

Annual tune-ups help you avoid surprise repairs, protect your warranty requirements, and sustain comfort all season.

Local Service Area

We proudly serve Los Angeles County and nearby areas: Orange County, Ventura County, and Western Riverside County. From coastal homes to inland valleys, our crews arrive prepared for the unique demands of Southern California properties and building codes.

Signs Your Furnace Needs a Tune-Up

• Uneven heat or rooms that never feel right
• Rising utility bills without a change in use
• Short cycling, odd noises, or persistent odors
• Dust buildup, worsening allergies, or dry air
• It has been more than a year since your last maintenance

If you notice these issues, schedule service before peak season to secure the best appointment times and ensure parts availability.

Complex Homes and Custom Solutions

Large homes and multi-zone systems demand an engineering mindset. We evaluate duct design, return air sizing, and control strategies to correct underlying causes—not just the symptoms. Whether you have a standard gas furnace or a hybrid setup with advanced controls, our team diagnoses precisely and solves for total-home performance.
