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.
DG is our go-to HVAC company across all of our projects for the past five years. They are the best and their customer service is second to none. Their office is very responsive and rarely do we ever have any problems with them. If there is the rare issue, they don't hesitate to help us find solutions to any issues on site. We can't say enough good things about DG HVAC and look forward to working with them on all of our upcoming projects.
DG is great to work with, the staff is friendly and knowledgeable. I appreciate that this company values Veterans and provided a military discount for our Mitsubishi Heat Pump system. We have had the system for over two years now and DG comes out every six months to inspect, clean, and change the air filter. I highly recommend DG Heating and Air Conditioning!
Excellent service from DG Heating and Air! Brandon was fantastic - he provided quick, efficient service and gave us straightforward, honest advice. Instead of trying to oversell us, he focused only on what actually needed to be fixed and took the time to explain how to properly maintain our systems for years to come. Really appreciated his transparency and expertise. Definitely gained a long-time customer - we'll be using DG Heating and Air for all our regular maintenance services going forward. Highly recommend!
