“Brandon did a fantastic job troubleshooting, optimizing, and servicing our AC - Heaters. He's a really great person to interact with as well.”
— Halfdan Hussey
“DG heating and air conditioning company gave me an exceptional experience last year. They upgraded my home air conditioning system using excellent workmanship and a very competitive price.
After spending my entire career in the industrial air conditioning industry, I was very impressed with DG's workmanship and professionalism. Thank you DG for a job well done!”

“Brandon from DG Heating & AC saves the day! Our AC suddenly stopped working and Brandon quickly diagnosed that we had a burnt wire, fixed it, checked our breaker panel and HVAC filter and gave us tips on how to make sure our AC unit runs efficiently. He explained everything clearly and thoroughly which I really appreciate. I hope we don’t have more HVAC issues, but if we do, I will most certainly call DG again.”
— Yun Ong
“DG Heating and AC is a great company to work with. We were so impressed with Brandon B. who came to our house to help diagnose correctly why our furnace stopped working and knew where to get the control board to fix it and came back promptly, saving us from the cold temperature. Brandon is very friendly, knowledgeable, professional and easy to work with. Thank you so much for saving us money from not having to replace our furnace Brandon!!”
— Jennifer D
“[Update Nov 2024] DG Heating & Air Conditioning continues to be an AWESOME choice for HVAC needs. They are professional, prompt, and use great materials. We had issues with the furnace and they were able to get a technician, Brandon, out to us in the same week. Brandon was AMAZING. He was professional, friendly, and took photo records of what was going on with the furnace. He completed the job and we talked at length about what the issue was. He also gave great tips on how to maintain the system, and which filters to get for the future. Only great experiences many years in, and can't recommend DG enough!
John and Mike are consummate professionals who won't look to upsell you on anything. Their team is speedy, thorough, and focused on delivering value to the customer. We couldn't be more happy with the HVAC unit they helped install on an older house. They've always been respectful and prompt in their responses. Can't recommend them enough!!”
— Eric Wang
“I looked around for a contractor to electrify my house and convert my HVAC gas/elec unit to an all electric heat pump for heating and cooling. DG was by far the most knowledgeable and responsive, with plenty of experience doing this. They did an excellent job on the installation. A year later I had some minor service issues. They responded quickly and resolved them (a dirty air filter, my fault).”
