Get matched with top air conditioning pros in Hopkinton, MA

"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"SumZero Energy Systems have been excellent in the last several months with supporting the replacement of my air conditioning system in my old condo as well as servicing my furnace. A price comparison with other local companies also prooved SumZero Energy Systems offered the best price. When I purchased a home a few months later, I called them to take a look at my air conditioning system and furnace because I felt as though they had provided such excellent service in the past. It was a no-brainer to ask for consultation regarding the heating and cooling systems in my new home! When I contacted them for assistance or consultation, they are usually quick to respond and provide appointment times had a very convenient window! They have shown up on time to all of the appointments I have had. David S. has always taken the time to explain everything thoroughly and answer all my questions. I highly recommend SumZero Energy Systems!"

"In the heat of the summer, our air conditioning shut down. I was worried that I was going to have to spend several thousand dollars to replace it. G & C came out to diagnose the issue and had it solved within an hour. They educated me about Maintainence so that this doesn’t happen again. Very happy with the service and professionalism. I will definitely be using them again!"

"One radiator wasn't working due to air - Ray came back the next morning (on a Saturday!) and made it right. Very pleased!"

"Very fast service - had air conditioning condenser not working on a 90F day - he called - showed up within an hour, fixed within an hour! Very happy!"

"My AC went out 2 days before a heat wave. I got a detailed estimate right away and signed immediately. The crew showed up next day and worked a long hours replacing all the equipment in the attic. My family was back online just in time to beat the heat. All the staff we worked with were clean, professional , hard-working people. I highly recommend to everyone."
