Maintenance and repairs are essential for promoting safe operation and prolonging the life of your furnace. Cleaning burners, measuring gas pressure and inspecting fuel lines are just a few of the services that we perform during an annual pre-season tune-up. Your furnace’s blower and air handlers also work hard in the summer when your heat pump or air conditioner is running, which means that maintenance will reduce costs in every season. Our NATE-certified technicians are trained to repair and maintain gas furnaces manufactured by Bryant and many other brands. We have fully stocked repair vehicles, advanced diagnostic equipment and high-quality parts. Our staff is trained to identify and correct furnace problems quickly and accurately. Plus, we offer a complete satisfaction guarantee on all services just to make sure that you’re happy and comfortable.


If your furnace is more than 15 years old, you could save money by upgrading to a new unit from Bryant. Systems that meet Energy Star standards for southern parts of the United States, including South Carolina, are 12 percent more efficient than baseline models manufactured today. High-tech gas furnaces have annual fuel utilization efficiency ratings over 90. This means that nearly all of the energy in the fuel is converted to heat. However, Bryant systems have other advances that enhance comfort and performance.

  • PerfectSense™ and Perfect Heat™ technology maintains temperatures that are 73 percent more consistent than competing models.
  • Intelligent sensors monitor actual conditions and adjust performance to minimize temperature swings while saving energy.
  • Multi-speed blowers reduce energy costs in the summer when paired with a compatible air conditioner or heat pump.
  • Increase your heating capacity and reduce costs by matching your Hybrid Heat® gas furnace with a high-efficiency heat pump.

Bryant furnaces are efficient and reliable, but they also come with an exceptional warranty, including lifetime coverage on the heat exchanger and a 10-year warranty on most major parts. We back this commitment up by offering a generous warranty on all labor and installation services. If you’re ready to upgrade, we can evaluate your home, select the ideal model and install your new gas furnace.

Call our office today, and we’ll send an expert over to assess your furnace. Free in-home estimates are also available in Hilton Head and other parts of Beaufort County.
