Our experience during the process of gathering information through purchase and installation was A+. Matt in Sales answered all of our questions and left us with great information for us to review as we considered our purchase. Meghan and Katie in the office were a pleasure to work with while scheduling our installation. Chris led the installation team and his 30 years with the company was evident. If you are considering HVAC installation, we highly recommend that you consider Callahan HVAC. Again, in our opinion, an A+-rated establishment. Tom & Barbara Leone Atkinson, NH
Entire team from sales, to business to install were extremely professional, courteous and efficient. A pleasure to work with them. Neat , clean install respectful of homeowner and property. Highly recommend!
I had a gas smell and contacted National Grid they had to shut off my furnace (less than 4 years old) due to output readings. Contacted furnace manufacturer who suggested finding vendor on website certified vendors. Contacted Callahan who was able to come out that day. Very professional and also explained why there was rust in my unit. Signing up for their annual maintenance plan.
I write this as a service to all consumers. I trusted this company and used them for many years. I was recently taken for over 7K for a repair that was not needed. Please, please, learn from my mistake and always secure second and third opinions. That was my bad for not doing that as I usually do. I had a dying pet and other issues going on. As a woman, I suppose I am a perfect target. Be careful out there.
Technician arrived on time; he was knowledgeable and professional. Very pleased with the level of professionalism and customer service.
I am very pleased with the service I received from Callahan. After dealing with a lemon of a furnace for the past two years, the technician Nick, was able to succeed where other technicians could not. After about 3 hours of troubleshooting he was able to get my furnace running better than ever before. I look forward to using Callahan for my future HVAC needs.
Probably better with residential than commercial.
Callahan installed a new steam boiler for me today. It was an extremely positive experience from start to finish. They were punctual, respectful of my house (placed tarps on rugs) and informative. Each step of the way, Callahan installers explained what was happening. Callahan was the best price of four estimates by far. Other companies proposed unnecessary services and overstated the complexity of the installation. Callahan came well-respected in the community and led to my decision to go with them. Callahan turned a stressful situation into a pleasant experience. I am extremely pleased. If you are searching for the right company to install your boiler, I highly encourage you to use Callahan. They were awesome. Rob - Methuen, MA
Need replacement of leaking expansion tank (relatively easy job) - they called to say they could not do til end of month!
Outstanding. Was able to resolve the issue climate control could not resolve for over 3 years.
Very punctual, very professional, very pleasant. Explained everything they did. Would definitely use them again.
Great customer service
I hired Callahan to relocate the gas line to my stove. I was extremely satisfied. I was happy with the price and they were quick to respond, courteous and completed the work quickly and with a high level of quality. Very professional, couldn’t have asked for a smoother process and better work!
