Best Heating & Air Conditioning / HVAC In Chelmsford

“We are very happy with the oil supply service AND furnace maintenance and repairs. This family-run business truly cares about their customers.“

“Prompt, excellent service and competitive pricing. Highly recommend!We had a shower valve break on the 2nd floor of our home. Water had leaked into our main floor and into our basement. We had to turn off the water to the house and needed someone to come out and help ASAP. We called Karl that day and he rearranged his Saturday so he could come over and help us out. He did a great job and fixed the shower without having to open up the wall. We are so grateful he was able to help us. We will be using Sully's for all of our future plumbing needs!“

“We had a great experience with Milltown. From the time I called to inquire about service until the job was completed. Each person responded in an attentive, professional manner.
We would not hesitate to call on Milltown again if we need anything else.
Thanks so much, Cathy and Steve“

“Competent plumbers who did the job efficiently and cleaned up completely before they left.“
