Our professional HVAC technicians are well-trained, experienced, and licensed. Don’t risk poor quality work, extended downtime, and potential reworks; instead, depend on experts who know what they are doing. 

You can trust Cassell Bro’s HVAC technicians to arrive on time and work professionally. If you need a company that specializes in commercial HVAC repair or installation in the Midlands, trust Cassell Brothers Home Services to provide reliable, friendly service and free estimates.

HVAC Installation and Replacement

Whether you need a new installation or your old HVAC system replaced, Cassell Brothers has you covered. We’ll do a load calculation to determine the best size of HVAC system for your building by looking at space, insulation levels, and points of leakage. We can easily install a commercial rooftop HVAC system for you and can set up zone controls for separated office buildings.

If you are replacing an existing rooftop unit, we’ll discuss removal procedures with you in our free HVAC installation quote. It’s a delicate procedure that needs to be carefully planned so that removal is done safely and without damage to the building or people.

Scheduled Commercial HVAC Maintenance

Just like all machinery, regularly scheduled maintenance is essential to keeping things running in top condition. Cassell Brothers offers routine commercial HVAC tune-ups in the Midlands, South Carolina, and the surrounding areas. We can work out a custom agreement to service all your HVAC units twice annually or quarterly, depending on how hard those units work and their age.

Expert and Speedy Commercial HVAC Repair

Need a new commercial HVAC contractor to fix and repair your unit? We’ll get to the bottom of your issue and determine why your HVAC unit is breaking down.

Cassell Brothers’ experienced commercial HVAC technicians are well-trained and know exactly what to look for. We’ve been around the block and know both common and uncommon problems that HVAC units run into, and how to repair them.

We also offer 24/7 emergency service commercial HVAC repair. Our technicians will arrive promptly and are fully stocked with the latest technology, equipment, and parts. We can get your HVAC system back up and running as soon as possible.

New Construction HVAC Contractor

As a general contractor, your reputation relies on the quality of not only your own work but those of your subcontractors. Missed deadlines, order changes, holdups, and inconsistent service from subcontractors can throw your project off schedule and out of scope.

Cassell Brothers understands that a whole project could be put on hold if the HVAC system isn’t finished professionally and on time. We pride ourselves on working well with general contractors and other trades from start to finish. 

Cassell Bros Protects Your Reputation Like Our Own

It does not matter how big or small your project is; you can trust Cassell Brothers to protect your reputation the same way we protect our own. We will deliver quality workmanship and integrity, as well as use the highest quality materials to fit capacity, local building code, and budgetary requirements.

Whether you are working on a manufacturing facility or a Class A office park, our experienced HVAC technicians can offer dedication and professionalism. If the unexpected arises during installation, we can provide additional on-site staff to handle the problem quickly and efficiently.

For new construction HVAC services, as well as commercial HVAC installation and replacement in the Midlands, choose Cassell Brothers. Contact us today.
