Commercial Furnace Repair in Calabasas

When your commercial furnace underperforms, every hour impacts comfort, safety, and bottom‑line productivity. #1 AC Guys delivers precision commercial furnace repair in Calabasas with the mindset of engineers—verifying combustion, airflow, controls, and ventilation to bring your system back to stable, efficient operation. Our mission is healthy air for healthy life, and that shows in every diagnostic decision and every part we install.

What we repair and optimize

• Ignition and flame safeguard issues: hot surface igniters, flame sensors, modules, and lockouts
• Short cycling, no‑heat, low‑heat, or rollout and limit trip events
• Gas train and combustion tuning: valves, regulators, manifold pressure, and CO safety checks
• Blowers, bearings, belts, VFDs, and ECM motors impacting airflow and static pressure
• Heat exchanger performance concerns and temperature rise imbalances
• Economizer faults, outdoor air dampers, and ventilation balance for IAQ
• Rooftop units, packaged systems, and makeup air furnaces serving large spaces
• Thermostats, BAS/BMS integration, economizer logic, and sensor calibration
• Filtration and particulate control improvements supporting healthier indoor environments

We support retail centers, offices, schools, hospitality, healthcare offices, light industrial, and multi‑tenant properties across Calabasas and greater Los Angeles County.

Why businesses choose #1 AC Guys

• 80+ years of engineering experience across four generations—built for complex, large‑scale projects
• Factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Root‑cause diagnostics using combustion analysis, airflow measuring, and data‑driven testing
• Healthy‑air focus: cleaner combustion, balanced ventilation, and lower contaminants
• Clear options: repair vs. replace guidance with lifecycle and energy impact in mind
• Coordinated work windows for minimal disruption to tenants and operations

We also understand procurement. When you need fast parts availability, we can source OEM‑grade components through reputable supply channels, including AC Pro, to shorten downtime and maintain consistency across your equipment fleet.

Our repair process

• Stabilize and make safe: verify gas leak safety, power, combustion air, and venting
• Diagnostic testing: ignition sequence, gas pressure, temperature rise, static pressure, and controls
• Transparent plan: prioritized scope with costs, timelines, and estimated energy impact
• Quality parts: OEM‑grade replacements and code‑compliant materials
• Commissioning: verify ignition, flame stability, airflow, and CO within safe thresholds
• Documentation: readings, parts replaced, photos, and maintenance recommendations

After repair, we tune for performance—optimizing burners and airflow to help reduce utility spend while improving comfort and IAQ.

Rapid response on your schedule

Whether it’s an unexpected heat outage or chronic short cycling, our Calabasas team responds fast with flexible scheduling and coordinated access. We work closely with facility managers, GCs, and ownership to keep business moving. Same‑day and priority options are often available during peak season.
We service Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County.

Preventive maintenance with an IAQ lens

Proactive care is the most cost‑effective way to protect uptime and indoor air quality. Our maintenance programs are engineered to stabilize combustion and airflow while reducing contaminants that affect occupants and equipment.

• Seasonal combustion tuning, sensor calibration, and economizer verification
• Filter strategy upgrades (right MERV for the application) and pressure drop tracking
• Belt alignment and tensioning, bearing lubrication, and VFD health checks
• Duct and cabinet sealing to reduce leakage and improve delivered BTUs
• Ventilation audits to balance outdoor air with energy savings and comfort

Results you can feel: steadier temperatures, cleaner indoor air, fewer service calls, and a clearer path to long‑term capital planning.

About parts, brands, and AC PRO

We repair most major commercial furnace makes used throughout Southern California, including systems built with AC PRO components. To minimize downtime and maintain performance, we source OEM‑grade parts through trusted supply channels such as AC Pro when appropriate. Training for our engineers includes manufacturer instruction with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We do not imply endorsement or authorization by brands unless explicitly stated.

Built by engineers, for real‑world buildings
