Who We Are

United Service Specialists Heating & Air Conditioning

With United Service Specialists Heating & Air Conditioning, you can always be assured of quality workmanship. With over 150 years of combined experience in the heating and air conditioning industry we have worked on a plethora of residential and commercial projects in Maryland & D.C. We are committed to ensuring the longevity of our company and relationships by providing and exceeding customer satisfaction in all areas of service. It is not just the knowledge of how to service and install, but it is the pride in the craft of being a great heating and air conditioning contractor. Pride in our work is what distinguishes us from other contractors. It’s our attention to customer service and setting up your appointments, to the work performed, communication before, during, and after the work is completed, and the warranty we stand behind that sets us apart. We take PRIDE. We leave our work area as we meet it, and we will make sure you know how to operate and take care of your unit after installation. Our commitment to quality workmanship is because of you, our customer.
