Range of HVAC Systems We Install

When you choose First Class Plumbing and AC, you’re getting a complete HVAC solution built to perform under Riverside’s demanding conditions. We install trusted brand systems using the latest energy-efficient technologies to save you money and ensure year-round comfort.

We also prioritize environmental responsibility. Our team follows eco-friendly practices, including proper refrigerant recovery, recycling old equipment, and responsible disposal of waste materials.

We install:

  • Central Air Conditioning Systems: Perfect for cooling your entire home efficiently.

  • Gas and Electric Furnaces: Reliable, powerful, and designed for comfort on cold nights.

  • Ductless Mini-Splits and Zoned Systems: Great for homes or offices without ductwork or where targeted comfort is needed.

  • High-Efficiency Heat Pump Systems: Versatile systems that handle both heating and cooling while keeping energy costs low.

  • Commercial Rooftop and Packaged HVAC Units: Ideal for businesses that demand performance and reliability.


Every system we install is engineered for comfort, reliability, and maximum energy savings under Riverside’s demanding climate.

Our Installation Process: From Consultation to Turnover

Our HVAC installation process is thorough and customer-focused, ensuring that everything is done right from start to finish.

Consultation & Assessment

We start with an on-site assessment of your current HVAC system, ductwork, insulation, and electrical setup. We’ll talk through your comfort needs, preferred temperature zones, energy efficiency goals, and budget. 

If needed, we’ll review your energy usage history to better understand your system’s demands. From there, we recommend system options tailored to your home or business.

Load Calculation & Right Sizing

We use industry-standard methods like Manual J, Manual S, and Manual D to size your system correctly. Why does that matter? An oversized or undersized unit wastes energy, shortens system life, and increases your costs. We make sure your HVAC system matches your actual load for peak performance.

Permit & Code Compliance

We handle all city or county permits and ensure your system complies with California Building Energy Efficiency Standards. Our team coordinates inspections so you don’t have to worry about a thing.

Installation & Integration

Once the plan is approved, our team installs your HVAC system properly and efficiently. We carefully position outdoor and indoor units, seal and insulate ductwork, and handle all electrical connections, thermostat wiring, and refrigerant charging. 

If your system includes a heat pump or gas furnace, we manage plumbing and gas lines too. Before we wrap up, we balance airflow, test pressures, and confirm that everything operates as it should.

Testing, Verification & Performance Tuning

We don’t just turn it on and walk away. We run full tests: checking for leaks, airflow efficiency, temperature accuracy, and system noise. We also perform safety checks for gas pressure, carbon monoxide, and refrigerant levels to ensure optimal operation. When everything passes inspection, we walk you through your new system and show you how to get the most out of it.

Preventive Maintenance & Ongoing Service Plans

Your HVAC system is an investment, and keeping it maintained protects that investment. That’s why we offer maintenance contracts that include semiannual cleanings, filter replacements, and system diagnostics. Properly maintained systems can use up to 15–20% less energy than neglected ones.
