When your Midea commercial furnace or rooftop package unit struggles, every hour of downtime impacts revenue, comfort, and safety. #1 AC Guys delivers high-accuracy diagnostics and durable repairs for businesses throughout Los Angeles County and neighboring Orange County, Ventura County, and Western Riverside County. As a fourth-generation family of engineers with 80+ years in engineering, we’re built for complex heating challenges and mission-critical environments where getting it right the first time matters.

What we repair on Midea commercial systems

• Ignition assemblies, flame sensors, gas valves, and combustion controls
• Heat exchangers, draft/inducer assemblies, and venting issues
• ECM and PSC blower motors, belts, bearings, and VFDs
• Control boards, relays, transformers, and low-voltage wiring faults
• Economizers, dampers, actuators, and sensor calibration
• Thermostats, BMS interfaces, and staging/sequencing problems
• Airflow and duct static pressure imbalances affecting comfort and IAQ

We focus on accurate root-cause analysis so your repair lasts. Our process protects your equipment, energy budget, and operations while aligning with manufacturer specifications.

Precise diagnostics that save time

Our engineers combine field experience with instrumentation: combustion analysis for safe and efficient firing, static pressure mapping to verify duct and filter performance, thermal imaging to expose hidden heat loss and electrical hotspots, and data logging to catch intermittent faults. The result is a clear repair plan, verified results, and fewer call-backs.
We document findings for property managers and facility teams so you can track asset health and plan proactively.

Safety and compliance for LA businesses

Commercial heating requires a safety-first approach. We perform make-safe steps, verify combustion air and venting, confirm gas pressures and leak-free connections, and test safeties and controls. Our work is aligned to local code requirements and Midea guidelines, helping you maintain compliance while protecting occupants and equipment.
