We had central air but we have a sunroom that is mostly windows. The room gets extremely hot in summer even with shades down. The room has ac ducts but the central unit works really hard to cool house. most of the time the sunroom heats up the house. Diamond comfort put a minisplit in Sunroom. I think it is really efficient. Only because the big central unit only comes on at a certain temp. It's like now that the sunroom is cooled the bigger one is not on as much. Diamond did a great job handling everything from install to paperwork. I am very happy with this unit. read more

Several years ago, we engaged Diamond Comfort to install 2 mini-spilts in our home. They did a great job and handled all of the paperwork for the various rebates available to us. We have since moved, and in the new house we have two pre-existing mini-splits, whose last service was unknown. I called Diamond Comfort to come out and service the units. The technician (Aleisha) was prompt and efficient. She asked a few questions about how the units had been operating to ensure she addressed our concerns, and performed the maintenance, giving us peace of mind for the winter. She also cleaned up, leaving no trace of any equipment or cleaning supplies. We highly recommend Diamond Comfort for installation and servicing. read more

This family-owned company provided excellent service. They were prompt, informative, and professional in providing me with an estimate for a mini-split. Once I pulled the trigger, the installation was quickly scheduled. The crew was on time, knowledgeable, clean, well-organized, and thoroughly professional (not to mention, nice). I strongly recommend them. read more

I met with diamond comfort 2 months ago and today they arrived to install my heat pump mini split system. I now have four inside units and a large outside unit to handle all my heating and cooling needs. They are incredibly professional and kind. I highly recommend them. The rebates the government is offering right now made this a no-brainer. read more

See all

We chose Diamond Comfort to install a whole house heat pump/mini-split system. They were knowledgeable and professional and do good work. Best of all they stand behind their work. When we needed to install heat and AC in a new addition going back to Diamond Comfort was the obvious choice. We're glad we chose Diamond; you will be too. read more

Diamond Comfort installed a heat pump and back up furnace at my residence just prior to Thanksgiving. They are a Mass save approved contractor and very familiar with the loans, rebates, and nuances of the Mass save programs and energy audit. I secured 5 contractor quotations for my project and selected Diamond Comfort. I am glad I did. The quality of their work was excellent, and their pricing was very reasonable. Highly recommended. read more

I am personally so surprised to read two of these reviews. Pat and his wife and daughter were nothing but professional, punctual and informative. Emails I sent with questions were either returned promptly or followed up with a phone call. In fact, Pat took a look at our boiler free of charge to see why it wasn't working and then quickly fixed that problem on the same day he installed our mini-splits which we absolutely LOVE! They provide a great source of supplemental heat keeping our oil heating bills lower and provide cool comfort in the warmer weather. They have been nothing but genuine and helpful throughtout the install process, were by far the best quote we received, and followed up in person to assist us in learning how to use the splits. Additionally, they submitted the rebates and warrantee for us! Very happy with Diamond Comfort. read more

Diamond Comfort - Heating & Air Conditioning/HVAC Near Me - Southampton, Massachusetts

Pat and his crew just finished a large job at my home in Longmeadow, MA. Our furnace had stopped working so that needed to be replaced as well as an alternate HVAC system on the second floor (mini splits). Their work was impeccable. The mini splits are awesome and a huge upgrade. Our new furnace is working great and we also purchased a heat pump. (we basically needed everything)! The work was done in a timely and professional manner. I would highly recommend this company. read more

Great family owned company. Excellent service, reasonable prices, amazing workmanship.

I never do this. I am never "this person." But I think people deserve to know our experience. In March we contacted Diamond Comfort to install mini-splits in our home. Before we could start the work, we suffered a house fire that derailed us entirely. Diamond Comfort was completely understanding and we contacted them about converting our electric heat system months later when we began to rebuild. On November 1, we sent a signed contract back to DC to formally begin the work. They had been on site numerous times before and after 11/1 to measure and assess. We assumed everything was set. On 11/29, someone from DC called our general contractor to say they hadn't received the contract. We searched through and found the sent email and re-sent it. Laurie from DC then responded to say they were offended by a comment our GC had said and no longer wanted our work. We were furious. In subsequent phone calls and emails they refused to acknowledge their error and continued to blame us. Unfortunately, emails do not lie. They had the contract. They failed to schedule us and then panicked and looked for any excuse to cancel. They have additionally gone to impressive lengths to avoid accountability. You cannot run a business if you have zero customer service skills and continue to blame customers for your error. Truly, all this company had to do was apologize and try to make it right. Laurie, the person who caused all of this, responded with "I am sorry you feel that way" to an email I sent in an outrage. That is not an apology. That is a civil way of telling someone off. Truly, I am sorry for this organization. I am sorry they are so disorganized, I am sorry they don't know how email works, I am sorry they don't know how to properly run an organization, and I am sorry that I even had to write this. They truly left us no choice. We have a hard deadline for the repairs on our home as our insurance company will not pay for our temporary housing beyond a certain date and we are now at square 1 with our HVAC work. We now have to explain to our insurance company what happened and pray they extend us in our current temporary home, but trust in that we will also be filing a complaint with the BBB. Do yourself a favor and find a different company to work with. If they don't take accountability for this error, heaven knows that else they won't take accountability for. read more

This is my first review on any site like this... I'm not the type to post anything positive or negative. I'm only writing this because I feel the need to warn people about this company. Stay away. We signed a contract with Diamond, the owner came out to the house to do measurements for fabrication, but then due to a back office scheduling error, they had to back out of performing the work. They also had the nerve to blame us for their mistake. Not reliable. The friends who referred me to this company also have had issues getting them to make repairs to their mini-split system, which Diamond installed. They are not cheap either. My guess is that they agree to perform work for every potential customer and then only come through for those willing to pay the most. That said, if you're comfortable paying more than you should, you don't mind if working with a contractor who doesn't stand by their work, AND you fit into their schedule, I'm sure they're a dream to work with. Obviously, that wasn't my experience. read more

Diamond Comfort installed my mini splits today and I just had to write about how easy they made the entire process and how wonderful they are to work with. First, they responded very quickly when I called for an estimate. Aleisha came to review my home and make a recommendation based on what I was looking for. She was friendly and very knowledgeable and didn't try to oversell me. She listened to what I was looking for and provided advise and input. Their quote was competitive and after agreeing to go with them, they scheduled an appointment within 3 weeks--how convenient! Pat came out with 3 others to do the install. They explained the process, asked my opinion about placement of the units, and I couldn't believe how quickly they were done. They explained the units to me and they even provided me with completed paperwork for applying for rebates. They made the entire process very easy and stress free and they all were friendly and a true pleasure to work with. I would highly recommend them. read more

I am shocked by some of the reviews on this site for Diamond Comfort. In my experience this is not how the business operates. They are professional and stick to their word. It seems that these two comments are related and that they are not very reliable. If a company does not want to do work for a homeowner due to feeling uncomfortable by comments that homeowner has made they are not obligated to do that work. Also if it was so important to get the work done maybe it should have been followed up with a phone call or subsequent emails to ensure that they were scheduled for the job. Just my thought! I just had Diamond Comfort install 3 units for me and they were awesome to work with. Aleisha who came out to my home for the estimate was great and very informative, Pat came out with a couple guys for the install and he was great and did a wonderful job. They were on time and cleaned up after them self. Laurie in the office was very friendly and personable to talk to. I would highly recommend and have been recommending Diamond Comfort to all my friends read more

How do they operate a business? I was in the market to convert my house to a "mini-split" system and wanted an estimate from an "Elite Contractor". A young woman came over to my house. She stayed maybe 5 minutes maximum, couldn't answer anything more technical than where the units should go, and left saying she would send an estimate in the mail soon. 3 weeks later I called the office because I still haven't received an estimate and spoke to another woman (perhaps the same person). She said that "maybe they lost my information" and that she'll "look around and call me back later that day". She never did. This was 3 weeks ago. Bottom line, let's say even with an estimate, I will not let you touch anything in my house. How can they treat cash in hand potential customers like this and still be in business?? read more

In April of this year we decided to have a minisplit put in our bedroom and wanted a different company than the one who had done our kitchen as we were not satisfied with their service. So glad we went with this company. Aleisha co-owner came over - reviewed the area and answered all our questions. She was both pleasant and informative. She sent us the bid for her and her father to put in. They arrived on time - were professional and efficient. Any questions I had that were e-mailed to her were promptly answered. And in addition, she took care of filing all the rebates for us for a huge savings...which we have received. I dont know why we waited so long to put one in our bedroom. Thanks Diamond Comfort for the comfort... read more
