Commercial Furnace Repair in Oxnard, CA

Full‑Scope Commercial Furnace Repair—Built for Oxnard Businesses

#1 AC Guys is the fourth‑generation, family‑owned HVAC team Oxnard trusts for large and complex heating repairs. Our mission is simple: healthier air and dependable heat for a healthier workplace. With 80+ years of engineering experience and factory training from Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, we bring technical depth and real‑world practicality to every service call.

What We Repair and Optimize

We service most commercial heating systems found in Oxnard facilities, including rooftop package units (RTUs), split‑system gas furnaces, make‑up air units, and unit heaters. Typical issues we resolve:

• No‑heat or intermittent heat, lockouts, or short cycling
• Ignition failures, flame sensor and burner assembly problems
• Cracked or compromised heat exchangers and unsafe CO levels
• Blower/VFD failures, bearings, belts, and airflow imbalances
• Faulty economizers, actuators, and ventilation control
• BACnet/BMS integration issues and thermostat/control faults
• Energy waste from improper gas pressure, tuning, or sequencing

Our approach targets the root cause to restore reliability, efficiency, and indoor air quality (IAQ) while aligning with California code requirements.

Our Proven Repair Process

1) Rapid Dispatch and Assessment: We arrive prepared for Oxnard sites—industrial parks, retail centers, offices, and hospitality—fully stocked for first‑visit fixes whenever possible.

2) Precision Diagnostics: Combustion analysis, airflow readings, gas pressure checks, electrical testing, and control verification ensure we diagnose accurately and prevent repeat failures.

3) Code‑Compliant Repairs: We use OEM or approved parts and follow Title 24 best practices for safety, ventilation, and efficiency.

4) Performance Verification: Post‑repair testing confirms proper ignition, temperature rise, airflow, CO/NOx safety, and sequencing with your building controls.

5) Clear Reporting: You receive a plain‑English report with photos, findings, and recommendations to help you budget and plan.

Industries We Serve in Oxnard

We support property managers, warehouses, food and beverage, retail, restaurants, offices, education, healthcare, and light manufacturing. If reliability during peak business hours matters, our team is built for you.

Preventive Maintenance That Pays Back

Most emergency furnace calls are preventable. Our commercial maintenance plans include seasonal tune‑ups, combustion tuning, filter and belt programs, coil cleanings, economizer checks, lubrication, and safety testing. The result: fewer breakdowns, extended equipment life, safer operation, and lower utility costs—especially valuable during cool, damp coastal mornings in Oxnard.

Healthy Air, Safe Heat

As an engineering‑led team, we care about the air your staff and customers breathe. We verify ventilation rates, monitor CO risks, balance airflow, and recommend IAQ upgrades (filtration, ventilation control, and demand‑control strategies) that support a healthier indoor environment while protecting your energy budget.
