Commercial HVAC in Riverside, CA

Trane Distinguished Dealer of the Year. NATE-Certified Technicians. Serving Riverside Since 1989.

Since 1989, Lewis Air Services has provided commercial HVAC solutions to businesses across Southern California, and we bring that same depth of experience to Riverside, CA commercial clients. We’re a Trane Distinguished Dealer of the Year with NATE-certified technicians on staff, covering the full scope of commercial heating and cooling: design, installation, repair, maintenance, and replacement.

Commercial systems run harder and longer than residential ones. Larger floor plans, extended operating hours, and higher occupancy demands require systems designed for those conditions, and technicians who understand them. That’s what we deliver.

Commercial HVAC Services We Provide

Every commercial property has different demands. A restaurant operates differently from a medical office or a retail space, and the HVAC system needs to reflect that. We assess your building’s architecture, occupancy load, and industry-specific requirements before recommending or designing any system.

Design & Installation

We design and install customized commercial HVAC systems built around your facility’s actual needs. Whether your building calls for a rooftop packaged unit, a split system, or a more complex configuration, we size and specify equipment to match your load requirements, not just your square footage.

Repair Services

We service all makes and models of commercial heaters and AC units. Our factory-trained technicians can diagnose and repair equipment regardless of brand, so you’re not locked into a single manufacturer’s service network.

Preventive Maintenance Agreements

Scheduled preventive maintenance can reduce unplanned breakdowns and can extend equipment life. We offer service agreements that include filter care, system inspections, and seasonal tune-ups timed around Riverside’s demanding cooling and heating seasons. Most commercial systems benefit from at least two service visits per year.

Packaged Unit & Split System Replacement

When aging equipment reaches the end of its useful life, we manage the full replacement process from equipment selection through installation, with minimal disruption to your operations.

Riverside’s Climate & California Energy Standards

Riverside’s inland location means summers that regularly push past 100 degrees Fahrenheit, with sustained cooling demand that works commercial systems hard for months at a stretch. That same environment increases airborne dust exposure, accelerating filter loading and degrading indoor air quality and system efficiency between service visits.

California Title 24 sets mandatory performance standards for commercial HVAC installations and upgrades. We help Riverside commercial clients navigate those requirements, designing and installing systems that align with state energy efficiency mandates. We also advise clients on available incentives for energy-efficient technologies, which can offset upfront equipment costs.

Air Quality & Additional Commercial Services

Beyond core heating and cooling, we offer services that matter to commercial property owners managing multiple building systems.

Air Purification Products
We install commercial air purification products that address indoor air quality, relevant for offices, restaurants, hotels, and any space where occupant health and comfort directly affect business performance.

Duct Cleaning
Riverside’s dusty environment makes duct cleaning more than routine maintenance. Accumulated debris can reduce airflow efficiency and circulate contaminants through occupied spaces. We provide thorough duct cleaning to support system performance.

Backup Generators
We install Generac backup generators that can keep critical systems, including HVAC, running during power outages, helping protect your business from costly downtime.

Water Heaters
We install and service commercial water heaters, giving you a single provider for multiple mechanical systems.
