Douglas heating made it easy to get a whole new system at a price that beat the other quotes Our house needed it, and it seems to keep the house warmer/cooler at the same thermostat settings.

I love this company! They treat you like family and are so professional. They do what they say and when they say they will do it. Answered all my questions and did not take advantage of a single woman like alot of people will do. I will definitely be using them again and referring them every chance that I get. Thank you so much for your care and dedication!!

If anyone is looking for an honest and reputable business to purchase parts, a new unit or for service please give these guys a call. We purchased a new system last year after ours quit working and have been extremely happy with it. A follow up call a few days later to make sure we were happy with it was a nice personal touch too. I would recommend them to anyone.
