Recommended Customer Reviews
Jack S.In July I called Callahan to make an appointment for an annual check of my gas-fired steam boiler, which they installed a few years ago ($7,500). I had to wait almost five months because I was told they have to honor contracts that are a priority.
Spending $7,500 doesn't make a person a priority?
The appointment was for this morning at 8:00 a.m. and when I called yesterday to confirm the woman who answered the phone (I think she's an owner) told me the technician would be late because he has to take care of his new baby.
It's great he has a new baby but why do I have to sit around waiting for him to take care of a baby? I had to get to work so I called and canceled the appointment.
This business is run for the convenience and benefit of the employees and not for the benefit of the customers. They have no shame in taking money and providing little or no service because they have no business skills and care only about themselves. Maggie and Sue answer the phone and apparently inherited the business so you know what kind of service they provide.
Go ANYWHERE but Callahan for your heating and cooling needs.
Callahan completed a full replacement of our 25+ year old home air conditioning system with a new Carrier Infinity system. Kevin who dealt with the estimate and quoting process came out as scheduled and provided a detailed quote via email within a few hours. He was also quite helpful answering questions about options we were considering and the pros/cons of each. Never felt any sales pressure either, and he honestly talked us down from pursuing a much more expensive heat pump option because the ROI wouldn't be worth it. Many other providers likely would've just taken the extra ~$7k in sales.
The install team arrived on time on the day scheduled and completed the work in approximately 4 hours, which was impressive. Everything went as planned and we're very happy with the new system. It's late October so we haven't been able to really use it beyond a quick test, but it's noticeably much quieter than our old system, and we're looking forward to the increased eco-efficiency next summer. The team also did a good job of cleaning up any mess left behind and answering any questions we had before leaving.
I'm glad we opted to go with Callahan and would definitely recommend them.
I called for replacement of expansion tank that is leaking ( a relatively easy job). When they responded they said they could not get to me til the end of the month (two weeks away)
As always, Callahan came through for us. Repaired our AC during the first hot spring days when they were extremely busy. Somehow they worked us in. Brian was efficient, polite, considerate and caring. Can't ask for more than that. Recommend highly.

Robert O.Callahan AC installed an energy efficient multi zone Mini split in our mountain home where tradition ductwork was not be possible .
100% Heat efficient to -20* and ability to control from an app meaning when I get there the home will be at a great temperature.
Excited to have Cool Air in the Summers and Hoping to save a bundle on Heat in the winters
Ray V.Did an outstanding job from coming to assess the scope of work for a replacement water heater install, an accurate quote and the quick efficient and professional install and removal of the old unit.
Very pleased!
Joyce B.We called upon Callahan to install central AC. The whole team was terrific.
Matt was super professional in the initial meeting and project plan. John and Edwin worked tirelessly for three days to install all of the ductwork. And they were kind enough to take the old window units out of the attic for me! Kevin installed the condenser and even saved one of my favorite perennial plants that was going to be covered by the condenser pad by digging it up (in the snow!) I also liked their choice of the electrical subcontractor, David Electric, who did an outstanding job.
It is 32 degrees out today, but I will absolutely appreciate the AC on a hot and humid summer day. Thank you to all of you!
I recently had Callahan install a New AC System in my home. During my vetting process, I had 4 companies come to give me a Proposal. The Prices were all over the place and 2 out of the 4 did not even do Heat/AC Calculations to determine the size of my system.
Matt from Callahan took the time to explain what they would do and submitted a detailed Proposal for me to review. Matt scheduled the Installation 6 weeks in advance. They arrived as scheduled. Unfortunately, I had a Family matter that would not allow them to be on site for the 3 days as planned. When I discussed this with Matt, his office decided to add additional workers to install my System in 2 days to accommodate me. Whitey, John and their crews were respectful to my home, polite and neat in everything they did even though they had less time to do it. I highly recommend Callahan to anyone that is considering a new Heating or AC System for their home.

My call one week ago today has yet to b resolved. Maggie and Sue who work in the office cover up each others lies. No heat and they do not care. They sent out a service person this past Tuesday. His name,Johnathan and he never turned in an invoice, work order or whatever he was supposed to do. They lied in the office saying he had a personal emergency and was not in work but they would look into it and get back to me. Never called back. Called again and this time Maggie told me she would get the info the office needed from Johnathan the tech who came. Earlier Sue said he had a personal emergency and was coming in later. It goes on and on. Lie after lie. Do not use this company as the women in the office tell u what u want to hear and then NO follow through, instead of just telling the truth. They just don't care about ur issue and lie to cover up their lack of follow through.
I'm updating as they came today. They sent a very polite, knowledgeable young man who was kind and considerate. He took the time to explain and also wanted me to b aware, which I was, that all private businesses are working as hard as possible to help the folks that Columbia Gas has left out on a limb.
I appreciate his work and follow through.
If I could could give negative star I would. This company is totally unreliable and unprofessional. Do Not do business with them.
I called them and made appointment and due to the gas crisis in Andover, North Andover and Lawrence they moved my appointment to the following week. Two days before I called to confirm my appointment. After taking the day off from work they never showed up.
I called an the office manager was totally rude to me and she said she didn't have a plumber to send out. Is this a way to do business?
