When your building’s heat falters, #1 AC Guys responds with the speed and precision Anaheim businesses need.

We proudly serve Anaheim, greater Orange County, and nearby Los Angeles County, Ventura County, and Western Riverside County.

What We Repair

• Rooftop units (RTUs) and packaged gas/electric systems

• Economizers, make-up air, and ventilation integrations
• Ignition systems, gas valves, pressure switches, inducer motors
• Heat exchangers, blower motors, belts, bearings, and controls
• Smart thermostats, BMS/EMS integrations, and sensors
We also perform combustion analysis, CO testing, and airflow balancing to ensure safe, efficient heat after every repair.

Factory-Trained, 4th-Generation Expertise

Our family’s engineering roots span four generations and 80+ years. Technicians are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means you get manufacturer-aligned diagnostics, parts, and repair practices that protect warranty coverage and system longevity—especially on large, complex commercial systems.

Our Commercial Repair Process

1) Thorough Intake: We review symptoms, building usage, equipment history, and access needs to minimize disruptions.
2) Expert Diagnostics: Electrical, gas, control, and airflow testing with pro-grade instruments to find root causes—not just symptoms.
3) Clear Options: You’ll receive upfront pricing with repair paths ranked by urgency, cost, energy impact, and expected lifespan.
4) Precision Repair: OEM-quality parts where required, safe gas handling, and careful commissioning to spec.
5) Safety & Performance Testing: Combustion, CO, draft, and temperature rise checks; airflow verification; controls calibration.
6) Documentation: Photos, readings, and recommendations to help you plan budgets and avoid repeat issues.

Healthy Air, Safe Heat

Your furnace isn’t just about warmth—it’s about indoor air quality and occupant safety. We focus on sealed combustion integrity, proper ventilation, carbon monoxide risk reduction, and filtration improvements. Our mission is healthy air for a healthier workplace, with solutions that support comfort, well-being, and productivity.

Fast Service Across Anaheim & Orange County

We prioritize businesses in Anaheim’s key corridors and surrounding cities. Need after-hours or same-day service to protect operations? Ask about priority scheduling. We coordinate access, lifts for RTU work, and safety measures to keep your site compliant and your team productive.

Compliance You Can Trust

Commercial heating systems must meet local code and standards. We repair and commission with Anaheim and Orange County requirements in mind and can advise on Title 24, ventilation standards, and permitting needs when equipment replacements become the smarter option.

Transparent Pricing & Strong Warranties

No surprises—just clear, written estimates and work performed by seasoned pros. We stand behind our repairs with solid workmanship warranties and OEM-backed parts where applicable. You’ll know exactly what was fixed, why it failed, and how to prevent it moving forward.

Common Warning Signs—Call Us If You Notice:

• Uneven heat, cold spots, or rising energy bills
• Short cycling, hard starts, or ignition failures
• Unusual noises, vibrations, or burning odors
• Tripped limits, frequent lockouts, or fault codes
• CO detector alerts or ventilation concerns
Addressing issues early reduces downtime and protects equipment life, safety, and budget.

Preventive Maintenance That Pays Off

Ask about commercial maintenance plans tailored to your equipment and hours of operation. Routine inspections, filter strategies, belt and bearing care, combustion analysis, and seasonal tuning can cut energy use, avoid emergency calls, and extend asset life—especially on high-demand RTUs and large furnaces.

Built for Large & Complex Projects

From multi-tenant properties to production facilities and restaurants, we’re equipped for complex diagnostics, multi-system sites, and coordinated repairs with building management. If your job requires cranes, lift coordination, or staged work, our team handles the logistics.
