DG Heating & Air Conditioning, Inc. describes itself on Angi as having over 10 years of experience, with work running from central A/C installs to heat pump replacements. In a 2021 review, a customer said Derek was quick to respond to their request for a quote and had their mini split installed within a week. Another 2021 review said D&G installed a split AC and heat unit, that Derek the owner kept to his word and was on schedule, and that the work quality was first rate. In a 2020 review, a customer said DG quoted a Mitsubishi system with 2 compressors and 6 air handlers for heat and AC at considerably less than another company's quote, and spent a lot of thought laying out the system "with minimal image impact on the house exterior." In another 2020 review, a customer said the install of a combined propane furnace and central A/C took place just days after they first spoke with Derek, with minimal downtime while the old system was swapped out. A 2020 review said Derek accommodated the customer's tight schedule to design, price and install a complete ductless system in a matter of days. In a 2019 review, a customer said DG responded right away and installed a new thermostat.
Derek was quick to respond to my request for a quote and had our mini split installed within a week. He was friendly, professional, respectful of our property and meticulous. I highly recommend hiring DH Heating and Air Conditioning, you won’t regret it!!
Derek and DG Heating and Cooling is the service company that we all hope to find, but so rarely can. With D&G I got the real deal -- a company that knows their trade and gets the job done quickly and at a fair price. What a pleasure to NOT get the hard sell at an inflated price, pitched by a hired marketer with little knowledge (which is exactly what I got at two of the other, also highly-rated, AC service companies in the area)!
D&G installed a split AC and heat unit for me. Derek the owner was very professional, polite and kept to his word. His price was right on for the job and he was on schedule and the work quality was first rate. Also his electrical used for the job was the same. Highly recommend D&G.
Great service
I asked for 3 quotes First said job was too big Second said Mitsubishi was best followed by Fujica then Gree He said Mitsubishi was by far the best but very expensive so he quoted the least expensive Gree DG quoted the same total BTU output through 2 compressors and 6 air handlers (heat and AC) and was considerably less than number 2 BUT with the SUPERLATIVE Mitsubishi system Work was quick and neatly done DG spent a lot of thought laying out the system with minimal image impact on the house exterior Jennifer and I canâ t be more pleased with our choice of DG Heating and Air Conditioning System works marvelously at a very fair price
