Douglas Mechanical Services - For residential service, repairs, change outs, or new installation
We also install and service residential water heaters from smallest to largest. In addition, we install and service gas fireplaces as well as pool heaters.

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 your residential home.
