Residential Emergency Heating Service in Los Angeles

Why Los Angeles Homeowners Choose #1 AC Guys

We’re not just technicians—we’re a 4th‑generation family of engineers with 80+ years in engineering, dedicated to solving complex residential heating problems the right way. Our approach blends rigorous diagnostics, manufacturer-spec repairs, and a health-first mindset to protect your comfort and indoor air quality. From modern high-efficiency heat pumps to older gas furnaces, we bring the experience to fix heat loss quickly and safely.

Our team has completed factory training with Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), ensuring our work aligns with how these systems were designed to perform. That means faster troubleshooting, fewer callbacks, and lasting results.

What We Repair in an Emergency

• Gas furnaces: ignition, flame sensor, gas valve, pressure switch, limit switch, inducer, blower motor, control board
• Heat pumps and ductless systems: defrost issues, reversing valve, outdoor fan motor, sensors, compressors, refrigerant-related faults
• Thermostats and controls: communication errors, miscalibration, wiring faults
• Electrical problems: breakers, shorts, relays, contactors, fuses
• Airflow and duct issues: blockages, disconnected runs, filter and coil restrictions
• Safety and performance checks: combustion analysis, venting, temperature rise, and system protections

If your heater won’t start, blows cold air, cycles on and off, or trips the breaker, we can help. We aim for same‑day restoration and keep most essential parts on our vehicles to reduce downtime.

How Our 24/7 Process Works

• Arrival ready to repair: We show up prepared with advanced diagnostic tools and stocked service vehicles.
• Safety first: We secure the area, verify gas/electrical safety, and protect your home during work.

Throughout the visit, our focus stays on reliable heat, clean workmanship, and healthy indoor air—because your family’s comfort and well-being come first.

Health-First Heating, Healthier Living

Our mission is healthy air at home for a healthier life. Poorly performing heating can introduce safety risks and degrade indoor air. We evaluate filtration, airflow, and ventilation as part of emergency service and can recommend targeted improvements—like sealing critical duct leaks, right-sizing filters, or optimizing heat pump settings—to support cleaner, more comfortable air without overworking your system.

Transparent Service You Can Trust

We believe in clear communication, manufacturer-aligned repairs, and no-nonsense recommendations. You get documented findings, explained in plain language, and repair options that respect your budget and long-term comfort goals. We stand behind our workmanship and follow best practices that help protect your system’s warranty and performance.
