Commercial Service

While GreenDena's base of operations is in Pasadena, we provide services throughout Anne Arundel County, including Pasadena, Glen Burnie, Severna Park, Arnold, Annapolis, Millersville and surrounding areas to handle your commercial mechanical install and repair needs.

We install, maintain and service the following commercial heating and cooling equipment:

  • Heat pumps / Air conditioners
  • Mini Split Systems
  • Flex Systems
  • Geothermal
  • Furnaces
  • Thermostats
  • Controls
  • Ductwork Fabrication, Installation and Sealing
  • Insulation for Ductwork, Pipes and Attics

Commercial HVAC is often more involved than residential heating and air conditioning. When it's not working, it not only causes discomfort, but loss of production and business. We understand your commercial heating and AC needs and it will be our priority to get your business up and running again. GreenDena looks forward to working with you and handling all of your professional heating and air conditioning service requests.

  • The owner was polite, professional and on time. He beat all the other estimates and completed the work early in addition to arranging the county Inspector the next day. Truly it was the most pleasant experience I've ever had with a contractor.
