Our Services

Commercial Cooling Systems We Work With

Commercial properties rely on cooling equipment built for larger spaces and heavier demand than typical residential systems. Rooftop units are among the most common setups we service, offering a space-efficient way to cool large square footage without taking up interior space. Packaged systems, which combine cooling components into a single outdoor unit, are another common choice for retail spaces, restaurants, and office buildings throughout the area.

Split systems and zoned setups also play a major role in commercial cooling, particularly for buildings that need different temperature control across multiple areas, such as a retail floor versus a back office, or separate tenant spaces within the same property. Our technicians are experienced with all these system types, allowing us to recommend the right equipment based on your building’s layout rather than a one-size-fits-all approach.

What Your Neighbors Are Saying About Us

We have had a great experience with them for both AC service and our boiler. The service team is professional, knowledgeable, and kind. They also make a big effort to get your job taken care of as soon as possible.

Tom, Julian, and Collin did a fantastic job replacing my oil furnace with a natural gas one. This was a very involved oil to gas conversion and they did a fantastic job running the gas lines and installing the new water heater. They were very courteous and did a great job explaining everything. Fair pricing, I would highly recommend!

I've had to call Davis on several occasions with furnace issues. Each time it was fast responses pleasant & friendly technicians they were very informative & got my heater up & running fast. 5 stars from me.

Extremely happy with our experience. We scheduled a tune up thereafter and the technician Nick H professionally maintained our systems, gave us valuable recommendations, and personally rerouted some HVAC piping to help provide additional head clearance in our tight mechanical room without asking. Highly recommend all around.

Furnace was clicking but not igniting. Called Davis and they said they were backed up but would try to get to me. Half hour later they called and said a technician was on their way. Nick arrived and quickly diagnosed the problem. Am up and warming up! Great service! Would highly recommend

Warning Signs Your Commercial AC Needs Repair

A few common signs indicate that a commercial cooling system needs attention.

Uneven temperatures across the building
Weak airflow in certain areas
Rising energy costs
Unusual noises from the rooftop unit
Frequent short cycling
Warm air during operation
Increased customer or employee complaints

If you’re noticing any of these signs, it’s worth having a technician evaluate your system before it affects daily business operations.

Our Commercial AC Installation Process

Every commercial AC installation begins with a detailed assessment of your building’s square footage, layout, and cooling demands, since commercial spaces often require more complex planning than residential properties. Our technicians factor in occupancy levels, equipment heat loads from kitchens or server rooms, and the need to manage different zones of your building independently.

Once we’ve determined the right approach, we provide a clear, upfront quote so you know what to expect before work begins. Our team handles installation with attention to minimizing disruption to your business, scheduling work around your operating hours whenever possible. After installation, we test the entire system across all zones to confirm proper airflow, temperature control, and overall performance before considering the job complete.

Our Commercial AC Repair Services

When a commercial AC system breaks down, our technicians start with a thorough diagnostic to identify the actual cause rather than guessing based on symptoms. This includes checking refrigerant levels, inspecting electrical components, and evaluating airflow across the affected zones of your building. Commercial systems often have more components than residential equipment, so an accurate diagnosis helps avoid repeat visits for the same underlying issue.

We carry parts for many common commercial cooling repairs, which helps reduce the amount of time your business spends without proper cooling. Once repairs are complete, we test the system thoroughly to confirm the issue is resolved and that your building’s cooling is back to full performance across every zone.
