"Duct Kings came to clean out a dryer vent. They were very quick with their work and did a great job. They even documented the job with before and after pictures and videos which we appreciated. I would highly recommend if you're looking for a fast and reliable duct company"

"My AC failed the night before a business trip. Eric was willing to take my passcode and go in and fix the very old R22 system the next day for my wife. A week later, the refrigerant was low and system failed. Within 2 days, his Team was in again and replaced the system at a very reasonable price. Very professional, responsive and trustworthy!"

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day. There was a deadline for installing this part before tenants arrive. They did not care, would not m"

"Fixed two shower problems. One was linking and the other didn’t have enough hot water pressure. Jason was able to get a 29 year old shower stem unit replaced saving me hundreds of dollars on one bathroom. The second bathroom needed a water pressure adjustment again saving me hundreds of dollars."

"Frances is pleasant to talk with and was punctual and responsive. My problem was that he's probably too busy. When I received his invoice, he charged me for the recessed lights that *I* had already purchased and then I had to prove myself by showing him the receipt. He charged me 2x the Home Depot price for Romex (which I had 100 feet of in my garage, ready to go). He put in dimmer switches that didn't match the coloring of my house project (old switches were almond, new switches should have been white) and then indicated he thought I wanted almond color since those were in other places (so were the white!). He should have asked what color I wanted, but didn't and then didn't offer to replace them. This experience left a bad taste in my mouth, I'd not hire him again."

"Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs."

"We consider ourselves very lucky for having chosen New England Clean Energy as our solar installer.

We wholeheartedly recommend them."
