“Your technician Jake Thomas was a pleasure to work with! His performance was awesome and we were happy to be assisted by him!”
– John Daley, North Reading MA

“My wife and I have nothing but the highest praise for all of your personnel who recently assisted us when our furnace suddenly had to be replaced. We were in the midst of an unexpected emergency over which we had no control, at the mercy of a company previously unknown to us. Right from the beginning–when your team arrived to diagnose the situation–and then when your comfort advisor came and calmly set in motion a plan immediately to install a new furnace–and then when the install crew arrived at 7:30 am the next day (as promised) to install the new unit, on a Saturday, no less–EVERYTHING was handled with professional courtesy and expertise. We can’t remember another time when we have experienced such top service by people who could not have been better at their work or more considerate of us. We are deeply grateful to all of them. You are lucky to have them carrying your name forward!”
– Donald, Andover MA

“Your service man Howie was excellent! Thank you Howie!”
– Arthur, Merrimac MA

“I want to thank your company for being so great and easy to work with. The heat (is) working perfectly now. Many thanks.”
– David, Derry NH

“Your repair technician did a great job on the A/C and communicating what was going on. He’s very good with customers. You have a solid employee. Thanks for getting things running again.”
– John, Andover MA

“The team at Climate Design ensured I had a technician sent out immediately that was professional and could fix the issue. They were kind and sympathetic to the issue – and made me feel 100% comfortable that your company would ensure the situation was taken care of appropriately.”
– Karen, Everett MA

“Your service tech didn’t make me feel stupid because I didn’t completely understand the technical jargon. He made sure that he showed me everything he did and helped me understand how it all worked together. This is a very special quality in a service person. I wish all service people were like him.”
– Linda, Haverhill MA

“…Outstanding all-around service I received from the team at Comfort Design Systems!”
– Michelle, Tewksbury MA

“Mr. Thomas, I recently had the pleasure of having my central air replaced by your company. I wanted to write to you and compliment the crew that came out to my house and installed my new A/C. They were on-time, professional, thoughtful and did a great job. I can barely hear my new system (the air handler is over my head when I sleep!), there is no more whistling noise going through my large return, and I my upstairs and downstairs zones are working. By the way, before your crew left last Thursday they asked to see my other central air unit (my house has two). I showed them the condenser and the air handler. The company that had installed it had installed piping from the condenser in front of the area where I would replace my filter – making it nearly impossible to change. Well, your people took one look at that and said that that wasn’t right. They rebuilt the pipe so I could access the filter. This is what I call going above and beyond. I’m more grateful to them than you know, because every 30 days I would have to go through all sorts of contortions to get my filter in and out of there. Now it’s just open, slap it in, and I’m done. I’ll be recommending your company to anyone who asks.”
– Scott I.

“I am writing this note…to let you know what a great job your team did with our central AC installation. Larry is one of the hardest working, diligent, and most dedicated workers I have ever seen. I am an HR Director and interview/hire people on a daily basis and he was really one of the most dedicated and caring people I have seen in a very long time.”
– Stephanie and Michael, North Andover MA

“Dear Mr. Corso: On May 11th your company installed a heat pump air handler in my unit. The two gentlemen who did the work were outstanding. Both of these men did such an excellent job that I felt it warranted a letter letting you know that you have two highly skilled employees who are both professional and respectful and who go beyond what’s expected. I feel very comfortable recommending your company to my neighbors and friends.”
– Teresa, North Andover MA
