Commercial HVAC Services in Hillsboro, OR

Most HVAC companies offer commercial services as an afterthought — a line on their website that means they'll occasionally take a commercial call. At O’Leary Air, commercial work is part of our foundation.

Before founding our company, Kevin spent years as the lead HVAC engineer at the Moda Center, managing complex climate control systems for one of the Pacific Northwest's largest entertainment venues. He then served as the lead HVAC technician at Intel, maintaining precision systems for one of the most technically demanding facilities in the world. That experience is what we bring to every commercial job we take on.

Whether you own a small retail space or manage a multi-unit commercial property, you deserve a contractor who understands how HVAC systems behave at scale, how critical uptime is to a functioning business, and how to get the job done right without disrupting your operations.

If you own a local business, call (503) 743-0417 to learn more about our commercial HVAC services in Hillsboro, North Plains, Beaverton, Forest Grove, Portland, and Vancouver.

Commercial HVAC Services We Offer

We provide a full range of heating, cooling, and HVAC services for commercial properties, including: 

• Commercial HVAC repair. When your system goes down, every hour matters. We respond quickly, diagnose accurately, and carry a wide range of parts and equipment on our service vehicles to resolve most issues on the first visit. We work around your schedule to minimize disruption to your business.
• Commercial HVAC installation. We assess your building's square footage, occupancy load, existing infrastructure, ventilation requirements, and energy goals to install a system that performs reliably from day one. As a certified Daikin Comfort Pro dealer, we install the full Daikin commercial lineup, including package HVAC units and ductless systems, as well as Goodman equipment for budget-conscious applications.
• Commercial HVAC replacement. Aging systems are a liability. Declining efficiency, increasing repair costs, and the risk of an unplanned failure during business hours all point in the same direction. We make commercial replacements straightforward, from evaluating your current system and recommending the right replacement to handling all aspects of the installation and commissioning.
• Preventative maintenance. Proactive maintenance is even more important in a commercial setting than a residential one, where the consequences of a breakdown extend beyond personal discomfort to lost productivity, customer experience, and, in some cases, regulatory compliance. We offer maintenance agreements tailored to your system and schedule so your equipment is inspected, cleaned, and tuned before problems develop.
• Commercial ductless mini-split systems. Ductless systems are an increasingly popular solution for commercial spaces that need zoned climate control without the cost or disruption of adding ductwork. They're ideal for server rooms, additions, office buildouts, retail spaces, and any area where independent temperature control is a priority. 
• Commercial package HVAC units. Rooftop and ground-mounted package units are a common and practical choice for many commercial buildings. We install, service, and replace commercial package units from Daikin and other leading manufacturers.
• Gas lines. We install and service gas lines for commercial HVAC equipment, water heaters, and other gas appliances, ensuring all work is completed safely and to code.
• Thermostats and building controls. The right controls can meaningfully reduce your building's energy costs and give you better visibility into your system's performance. We supply, install, and program commercial thermostats and smart controls that integrate with your existing setup.

Why Commercial Clients Choose O’Leary Air

We respect your business hours. We understand that your HVAC system needs to work and that having technicians in your space during peak hours isn't always practical. We schedule around your operations and communicate clearly every step of the way.

Commercial HVAC work can be complex, but our pricing approach is the same as it is for every residential customer: clear, upfront quotes before any work begins without surprises on your invoice. We also guarantee our work. Every installation we complete comes with a written guarantee. Daikin equipment is backed by a 12-year parts warranty, and we cover labor for up to 2 years on new installations, so you're not absorbing unexpected repair costs right after a major equipment investment.

Industries & Property Types We Serve

We work with a wide range of commercial clients across the Portland Metro Area, including retail and restaurant spaces, office buildings, medical and dental offices, light industrial and warehouse facilities, multi-tenant commercial properties, schools and churches, and property management companies.

If you're not sure whether your property or project is a fit, give us a call at (503) 743-0417. We're happy to have a conversation and let you know what we can do.

Commercial Maintenance Agreements

Just as our residential U.S.A. Maintenance Plan protects homeowners from unexpected breakdowns, we offer customized commercial maintenance agreements designed around your specific equipment, usage patterns, and scheduling needs. Regular preventative maintenance keeps your system running at peak efficiency, protects your warranty coverage, and dramatically reduces the risk of a costly unplanned failure.
