Quality and Reliability You Can Trust

If We Can't Fix Your System, You Don't Pay — Period.


Serving Gaston, Lincoln, Cleveland, and Mecklenburg Counties


Since its beginning over a decade ago, FSM Heat & Air has grown into a full-service HVAC company that covers all aspects of heating and cooling—both for homes and businesses—in Gastonia, NC and the surrounding areas. We’re a company that is large enough to provide a fast response for whatever work you need done, but we’re also small enough to deliver personal attention along with that work. We offer free estimates on replacements and major repairs so that you’ll always know the cost before we get to work, and we do not charge extra for nights and weekends. Plus, if we can’t fix your broken system—you don’t pay!

We’re the HVAC contractors in Gastonia you can trust to protect your family’s comfort all around the year, or to handle your commercial HVAC needs so you always have content employees and clientele. Our motto is “Quality and Reliability You Can Trust!”


When the winter weather arrives and temperatures drop, you don’t want to rely on a heating system for your home that’s likely to fail on you—and you don’t want to rely on a heating contractor who’s likely to do the same thing. When you put your trust in our team of heating experts, you’ll receive the highest quality service for whatever work your furnace, heat pump, or other heating system requires. We offer excellent new installations and replacement, fast and dependable repairs from our experienced technicians, and a maintenance agreement that will keep your home’s heater in the best shape year after year, winter after winter.


One of the unfortunate side effects of homes being designed for increased energy efficiency is that less fresh air is allowed to circulate through them. Because of this, a high concentration of pollutants become trapped indoors and lowers the air quality. If this is a concern for your home, you should get in touch with our IAQ experts and find out how best to boost the quality of the air that everyone in your household breathes. We install a large variety of indoor air quality devices: air purifiers, air filters, UV lights, humidifiers, dehumidifiers, etc. In addition, our technicians provide air duct services to see that you have an airtight and efficient ventilation system.


The modern air conditioning system is quite a marvel of refrigeration technology. But that also makes it a device that is far too complex for anyone except trained HVAC technicians to work on. We want to make sure that your household enjoys the most pleasant summer conditions possible with a great air conditioner. We’ll dedicate ourselves to providing you with top quality cooling services, no matter the work you need done. We offer installation of central air conditioning, packaged AC units, ductless mini splits, and more. You can also put your trust in us for fast response repairs and thorough yearly maintenance.


As our business expanded, we also expanded into businesses. We’re not only here to take care of residential HVAC issues, but commercial ones as well. Our commercial HVAC services cover a wide spectrum, including the installation of rooftop units, commercial heating repairs, commercial air conditioning maintenance, and anything and everything in between. We’ll even help your business benefit from improved air quality with our commercial IAQ services. It’s our goal to see that your workers, customers, clients, etc. enjoy the most pleasant environment possible. Call FSM Heat & Air today and find out more about the extensive commercial comfort services we provide for Gastonia, NC and the surrounding areas.
