Premier installing commercial equipment


For over two decades, Premier Heating & Cooling has been providing commercial customers with the highest level of customer service and satisfaction. We know you have many options to consider when choosing a heating and cooling company for your business, that is why we listen first and foremost. We’ll take the time to talk through, evaluate, and implement the best solution to your unique heating or cooling situation. We are experienced in new installations, retrofits, indoor air quality, radiant heating, geothermal, small duct high-velocity heating and cooling, liquid chillers, steam humidifiers, and zoning systems.

Our technicians are chosen for their enthusiastic and pleasant attitudes and are trained to give courteous and efficient service. All our technicians have completed or are completing a five-year apprentice training program with Sheet Metal Workers’ Local Union #36. Once the apprentice program is completed, the technicians are tested to become individually licensed mechanics. Each technician is required to complete continuing education and training classes to maintain their mechanical license.

Most importantly, we won’t turn our backs on you once the job is done. We’ll stay with you every step of the way, answering all of your questions and problems immediately. You can take comfort in knowing that you’ve made the right choice with Premier Heating & Cooling.
