Commercial Products & Services

Our technicians are not only experienced with many different commercial brands but with expanding technologies as well. We supply quality parts and equipment from manufacturers like American Standard, Aprilaire, Buderus, Carrier, Daikin, HB Smith, Honeywell, Johnson Controls, Mitsubishi, Powerflame, Samsung, Trane, and Weil McLain, plus many others.
Douglas Mechanical Services technicians are trained to handle nearly every service needed including gas and oil fired boilers, gas and oil warm air heat, cooling, ventilation, and commercial refrigeration systems. We install and service commercial water heaters from the smallest to the largest. We also service all sizes and makes of commercial rooftop packages.

Furthermore, equipment left by past contractors (i.e. boilers, furnaces, rooftop units, compressors, and hot water heaters) can be easily removed and disposed of properly by our company. We can do this for even the largest commercial facility.
