"Bill was willing to install a heat pump system that I purchased, even though his default was Bosch. His son and helper did the install over two days. It was getting late when they finished and the unit worked, although it whistled. I let Bill McGinley know but couldn't get them to come out to resolve the problem for over a week. Bill figured out that air was being sucked in between the top bottom front panels on the ACIQ central unit and did a workaround -- taping over it. The manufacturer ACIQ was no help in acknowledging that there was a problem with their product. I made a mistake paying on the basis of the quote rather then requiring an invoice. When I tried to apply for the NHSaves rebate, they wanted an invoice. Bill was not very responsive in sending me the invoice. He did when I told him NHSaves would be contacting him. But he was very accommodating in doing the work i wanted done instead of doing what he was used to doing."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"We recently had a complete roof replacement. Before proceeding, we did comprehensive research of area companies and Vista came out on top, with good reason! All appointments were not only on time but were extremely punctual. We met first with Product Specialist Holly, who was enthusiastic, very knowledgeable and helpful. While at our home assessing the proposed job, Project manager Rick explained the entire process in layman's terms. The day of the job, Project Supervisor Marc arrived early and went over the entire job with the crew. All company representatives left us with a business card with their cell #'s to call if we required anything. The installation crew was amazing. They arrived early and began immediately. They were no nonsense, very focused and, worked like a well oiled machine. All Vista team members were polite and respectful of my special request to be cognizant around some of my more cherished trees & shrubs. Vista was fastidious in their care for my home and lawn, not one speck of debris was left behind. Vista, the installation crew, company representatives, everyone, exceeded our expectations. Vista stands behind their work and products. If you wish to relax after a major home improvement project knowing the job was done correctly, you will want to consider Vista. Dan & Kim Belchertown"

"Very professional. But could have cleaned up after themselves a little better in the attic. I had a small issue and they got back to me right away and took care of it. I would highly recommend McGinley and Sons heating and Air Conditioning to anyone looking to install central air."

"Working with Triumph was an amazing experience. The entire team is professional, knowledgeable, efficient, and well spoken. In New England where heating is an essential service I felt totally confident Triumph would do a superb job installing my new boiler. They even moved their schedule around to install the unit the very next day. I plan to hire them in the future for all my heating, cooling, and plumbing needs."

"Air Scrubbers Inc. sent two of their representatives Steve and Dave who arrived at my home at the appointed time. Steve and Dave demonstrated excellent customer service skills, pin pointed the problems with the central air system, solved the problems and offered recommendations to insure the central air system continues to operate efficiently. I was 100% pleased with the services Steve and Dave provided. In the days that followed the cleaning services they provided was very noticable.  The central air system is quieter, cools much quicker, and the air is cleaner. I would highly recommend Air Scrubbers Inc. especially (Steve and Dave) to anyone having a problem with central air system. Air Scrubbers Inc. does an excellent job. Thank you Steve and Dave.

"Gil was very professional and he took a lot of pride in his work. He did not take any corner when faced with problems and he made sure everything was done correctly and to code. Gil gave a reasonable quote after inspecting our old system to replace with a new heat pump. Installation were delayed due to personal issues but when we really needed heating once the temperature were dropping, he made it his priority to finish it. During installation there were issues with the old duct work which made the work more difficult. He didn't upcharge us at all to fix it. We very much appreciated in working with him and would gladly repeat doing business."
