Full-Service HVAC Support for Your Building

Cannell maintains a dedicated light commercial department. That matters because commercial work handled as residential overflow tends to get scheduled around residential calls, and a building owner feels that difference immediately.

We install, repair, and maintain rooftop units, split systems, boilers, Temp Control Systems, exhaust and supply fans, and make-up air units. Our technicians are NATE certified and trained on all makes and models on a regular, ongoing basis.

We have been a Carrier Factory Authorized Dealer since the company’s inception and hold the Carrier President’s Award for Excellence for 2019 and 2020. We handle any job, no matter how large or small.

Using one contractor across installation, repair, and maintenance also means the person diagnosing a fault already knows the building. On a property with several units and a control system tying them together, that history saves diagnostic time on every subsequent call.

Businesses and Facilities We Work With

Our commercial work is light commercial, and that is the honest description of the scope. If your building runs on packaged rooftop units, split systems, a boiler, or make-up air equipment, it is the kind of building we work in.

That covers a great deal of what exists along this stretch of the Gulf Coast, from storefronts and offices to shops and small facilities. What determines fit is the equipment on the roof rather than the sign on the door.

If your system is larger than our light commercial scope, we will tell you at the evaluation rather than after the work has started.

Commercial System Installation & Replacement

Replacement estimates are free and are conducted by the owner or a technician, not an aggressive salesperson. On a commercial building, that means the person quoting the job is the person who understands what it will take to install it.

Sizing carries real consequences here. Equipment sized to the old unit’s label rather than to the building’s actual load will short-cycle, leave humidity in the space, and cost more to run for its entire service life.

Financing is available with approved credit through First Financial and Wells Fargo Bank, N.A., and we accept cash, check, and major credit cards. Installation labor is warranted for one year.

Ductwork and controls get reviewed as part of the estimate rather than treated as a separate project. New equipment connected to a leaking distribution or a drifted control system inherits the problems the old equipment had.

Commercial Repair and Emergency Response

Repair calls follow the same sequence on every building.

Assessment. A NATE-certified technician evaluates the affected equipment and its controls.
Diagnosis. We identify the failed component and flag anything else heading the same direction.
Approval. You receive the repair cost before any work begins.
Repair. We complete the work with as little disruption to building operations as the job allows.

A diagnostic call is $85, or $75 for Service Agreement customers, and 99% of our service calls are repaired on the first visit because our trucks are stocked. Emergency service is available by appointment outside our regular Monday through Friday hours.

Service Agreement customers receive free priority service 365 days a year, with a technician at the door within 24 hours.

Preventive Maintenance Agreements

Commercial equipment fails on the day it is working hardest, which is also the day the failure costs the most. A maintenance agreement is how you move that risk off the calendar.

Our Service Agreement includes two performance tune-ups a year, energy-saving coil cleaning, free priority service 365 days a year with a technician at the door within 24 hours, and a one-year labor warranty with free return re-diagnosis.

It also carries 10% off replacement parts, 20% off repair labor, 5% off new equipment, and a reduced $75 diagnostic charge. On a $400 part, that discount alone is $40 back, and on a building with several units, those figures compound quickly.
