Engineer-Led Diagnostics for Reliable Heat

When you schedule residential furnace repair in Calabasas with #1 AC Guys, you get more than a quick fix. Our fourth-generation engineers apply 80+ years of engineering knowledge to pinpoint the true cause of issues. We verify airflow and static pressure, perform combustion safety and CO checks, inspect burners and heat exchangers, and test igniters, flame sensors, inducer motors, pressure switches, gas valves, boards, and thermostat controls. The result: repairs that last, safer operation, and consistent comfort.

We are mission-driven to deliver healthy air at home. That means we repair your heat and also look at filtration, duct integrity, and ventilation so your family breathes cleaner, safer air while staying warm.

Indoor Air Quality and Efficiency First

Your furnace is central to comfort and air quality. Our engineering-first approach helps reduce dust circulation, minimize combustion-related risks, and improve filtration. We can evaluate filter sizing and MERV ratings, recommend duct sealing or balancing where beneficial, and fine-tune blower settings to help your system run quieter and more efficiently.
Cleaner air and proper airflow also protect the furnace itself, helping prevent repeat failures and keeping bills in check during California’s cooler months.

Factory Training That Matters

Our engineers have trained directly with manufacturers at facilities operated by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This hands-on, factory-level perspective informs our diagnostics and repair standards on advanced residential systems. We service most major residential furnace and air handling systems found in Calabasas homes.

Repair vs. Replace — Honest Guidance

During every residential furnace repair in Calabasas, we evaluate system age, safety, parts availability, and efficiency to help you decide whether repair or replacement makes more sense.
