Air Conditioner Installers in Sudbury, MA

"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)!"

"Mr. Terry was awesome! This is my first review I am writing. I felt I needed to write something as his work was so outstanding. He repaired 16 windows and did it beautifully. Marvin's quoted over $40K!! He was able to do what was needed for much much less. He was honest, professional, meticulous, extremely knowledgeable and kind. Miles above the window brand quotes which are ridiculous. Would strongly recommend if you need any window repairs!!!"

"He was prompt and always responsive. He does a professional job. - very thorough. I would definitely hire him again."

"responsive, and I only use him for HVAC."

"timely work, appreciated!"

"I hired them to remove and replace my attic pull down stairs as well as add plywood flooring in my attic. The two craftsmen, Joe & Chuck arrived on time and never stopped working until they finished the job. They were very friendly, courteous and knowledgeable. They also cleaned up the work area and removed the debris."
