Knoxville Heater Repair & Installation

Experienced Commercial Heating Installers in Tennessee

In a perfect world, your commercial facilities would always operate as designed. Nothing would break down, and so nothing would interrupt your regular business operations. But in the real world, old boilers and furnaces sometimes need repair. At Del-Air Mechanical, we can keep your system operating at its peak—or provide new installation when it’s time to upgrade to a more energy-efficient model.

We provide an array of commercial heating solutions, allowing you to choose what’s best for your business based on efficiency, installation, and operating costs. We also offer building automation services to make monitoring your business's heating system a breeze.

Commercial Heat Pump Services

Heat pumps work pretty much exactly like the reverse of an air conditioner. In fact, they can be switched between heating and cooling modes and use the same coils and refrigerant for each process. During winter, the outdoor coil absorbs heat, which is then transferred to the indoor condensing coil and released into the building.

Heat pumps come with several advantages including:

  • Single-zone or multi-zone heating
  • Less drying than traditional furnaces
  • Deliver more heat than is consumed in energy usage
  • Lower operation cost than other systems

Del-Air Mechanical offers a wide range of commercial heat pump services in Knoxville, including installation, repairs, and maintenance. Contact us today to request a complimentary estimate.

Energy-Efficient Furnaces

Though heat pumps tend to be the most energy-efficient option, new furnaces are more efficient than old models. The best furnaces on the market today have 90% or more AFUE—meaning more than 90 percent of the energy from the burnt fuel is turned into heat without energy loss.

Professional Boiler Maintenance

While we recommend heat pumps or efficient furnaces for new installs, we can also maintain your existing boiler system. Boilers require regular inspections and professional maintenance for safety; our technicians can check for rust and corrosion, test the function of safety mechanisms, and more.
