"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"I contracted with Grant Heating & Cooling Inc. to install HVAC system in my home in the spring of 2024. They were very professional and did a very good job. In the winter of 2025 I had a minor problem with one of the Mitsubishi heat pump system units. The company was quick to troubleshoot the situation. The technicians were courteous, knowledgeable about the system and thorough. It required several visits to diagnose the problem and fix it. The manager, Nick was very responsive to the situation which required bringing out an expert from Mitsubishi. All of this work was covered under my warranty. The problem was fixed and I could not speak highly enough about the company’s policies and customer service. I would highly recommend them for all facets of their work and standing behind their installations. I am very happy to be working with them for my continued maintenance. They are an excellent company. Sincerely, Susan Coursey"

"We've never had luck with major home modifications—this was smooth sailing the entire way. Our project was a teardown and complete re-side, and Cocos did a fantastic job. We have a tricky home with a lot of angles that make no sense—Cocos did a brilliant job strategizing how everything should be executed, and the 50-year-old home looks brand new. Danielle, Keith and Matt not only executed at the highest level, they stayed in communication literally every day to make sure there were no surprises and that we were happy with the progress. If you're looking for a home siding partner, don't hesitate to hire Cocos. They were top notch and we are very happy/"

"The installation of my Hvac system could not have gone any better. Joe was on top of everything from contacting me when he couldnt make the original installation date, to following up and waiting on me to have the electrical upgrade, was on time and punctual both days its took to do the work and made sure he explained everything and I had a clear understanding of everything. I would definately recommend and hire again for any Hvac needs"

"I recommend this company without hesitation. Chris, the technician, and Novis, his assistant, did a wonderful job. They arrived on time, were extremely professional and worked very efficiently. They made sure everything was secured before they started the actual power washing. When the job was completed, they wanted to make sure we were satisfied with the result, which we certainly were. This is a first class company."

"Well they did as was original explained by the sales person plus they explained in detail as they worked... They had to pump more cellulose in my attic than the had anticipated so job took a lil longer... But long story short I was pleased when they left bc I watched n they seemed to do a throrow job... Well it's a lil over a month since n right away I noticed my apt was not cold any more if any thing I had to lower my thermostat to 65 bc the apt was like a Sauna if I kept it at 69-70 like before! I jus recieve my first Nat'l grid bill and it was over 100 dollars less... And according to the bill it shows the usage from last year compared to this year... Very significant! Well I'm warm n cozy n there is a blizzard going on at this moment! I plan to comeback n update in another month or two to report if the savings r consistent... But so far getting this done I feel is the best n smartest decision I've made. For those who want to compare sq ft to price... My area was 70 sq ft plus the space between my ceiling n roof in two rooms... One room they stated was 2 ft of space that had to b filled ... Plus they were sweet enough to take photos of the condition of my roof for me so I didn't have to climb up which I had planned to do to check the condition of my roof... They saved me the trouble...I was able to evaluate work that I needed to do in the near future by the photo... So Thanks to Angies list and to JC Home Care n thier very professional n friendly tech guys...Highly recommended!

"Bill and his crew did the install seamlessly. I have used East Coast Mechanical in the past for a new boiler installation as well. They keep their appointments, they stand by their work, they return calls in a timely manner and their workmanship was flawless. They removed the air handler from the attic and installed the new one covering the floor and carpet so as not to get anything dirty. When they finished you didn’t even know they were here except for the temperature change. I would without hesitation recommend ECM for any HVAC work you need done."
