"Guy was hands down the best HVAC person we have ever had help us in Boston. Totally transparent, professional, easy to work with. If you need help, I would recommend asking for Guy to come out if possible."

"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"I called the company on Sunday evening and they responded promptly early in the morning. My system was installed by them 3 years ago but somehow I missed last year's annual servicing. With the current heat wave it was severely underperforming. They sent out Robert Duclos within the hour. He diagnosed the problem---not enough Freon in the system, grass and mulch build-up in the compressor, valves buried under the landscaping--and fixed it all for the price of the annual service contract. I would definitely recommend them for anyone needing central a/c work."

"Fantastic. In and out in within 2 hours. Cost $15,000 less than another Angie's List HVAC service person quoted me."

"I had the pleasure of having G&C come to my home to repair a leak within my kitchen cabinet. Not only did the technicians arrive promptly, but they walked me through the repair process step by step, working in a clean and diligent manor. I highly recommend G&C for all of your plumbing and HVAC needs!"

"I bought an Angie's list offer for Air Duct cleaning from Duct King. They called me to schedule in a timely matter. Showed up on time. Did a good and a thorough job. The technician was professional and worked hard. Better than other Air Duct cleaning companies I used before. I highly recommend them."

"We called during a heat wave on a holiday week when our A/C broke, so we knew it would take a while to get an appointment, especially as first-time customers. They were able to immediately schedule us for just under a week out, and let us know up top about how their services and payments, etc. work. We actually called another provider simultaneously to see if they could come earlier, but they just ended up giving us the runaround for days instead of just saying they were too busy. They confirmed a smaller time window the night before, and showed up first thing the next day. Abner was awesome, and it was such a huge relief to have someone so nice and professional, explaining everything like we didn't know anything about HVAC (because we don't). He broke down 6 options for us to move forward ranging from the minimum service fee for the cleaning all the way up to addressing everything he saw that was weighing down on the system. He explained which options we could wait on and which ones were higher priority, etc. It feels so rare to get a home service provider with this kind of professionalism these days. I wish these guys did automotive! I didn't rate them on price because I don't have a good comparison. But we will definitely be using them moving forward based on reliability, customer service, and professionalism."

"Dean and Anthony provided our HVAC and dryer duct service today. They were both courteous, honest and efficient. Dean provided quick and easy to understand additional options for service. They did a great job and we asked for them to come back again this time next year for additional service on our HVAC system."
