Customer Reviews

I choice DG after contacting 5-6 installers and obtained 3 quotes to install a heatpump. I was not shopping for price, more concern with their installation procedure and quality of work since the line-set will be hidden and inaccessible. DG did a great job and manage to thread the line-set inside walls. My install is a 2-zone setup and non-trivial because the 2 zones are far apart. Others propose to go with foundation install or outside conduit. I overheard one sentence when the planner talked to his partner 'it has to look good'. I know I have the right group. Their price was competitive but not the lowest.

I have been dealing with DG Heating and Air Conditioning since the very early days of the company. My furnace and AC system were installed by them. Annual maintenance is provided by them. Every employee I have dealt with has been prompt, knowledgeable and professional.
