Finally a plumber that doesn't make you wait two weeks for repairs. When the water or heat stops you need it working again immediately not in two weeks.

Daniel just left after giving me an excellent lesson on my thermostat! Thank goodness for Callahan and their talented employees!

Customer of over 15 years. Prompt professional service. Kevin MacDonald and the entire team are great to work with. Highly recommend.

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!

Callahan AC and heating installed my system and responded right away six years later when I had a problem with my AC system. Great installation and great response years later. Great company.

Provided baseboard and faucet plumbing services. Job was satisfactory and techs were polite. Had a small mixup with billing and it was promptly resolved and they went above and beyond. Recommended

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.

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!

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.

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.

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.

During current heat wave, I was provided with absolutely great service when my A/C failed. The office staff was very accommodating when I called. The tech, Justin, was an "ace" in solving my problem. He was extremely professional and knowledgeable. He thoroughly checked my system and discovered a wiring issue which he corrected. Callahan and Justin went far beyond great service and I am a very satisfied customer.

We have been using Callahan for years and we have had nothing but 5 star service. In about a week from now we will be moving and had an issue arise with our AC. Nick was sent out the same day and repaired the problem in no time...with a smile. I can't recommend this business enough!

Our outdoor faucet was making a loud, rumbling noise when we turned it on. I called Callahan and a technician arrived within an hour. He quickly diagnosed the problem, (it was the hose, not the plumbing), and we are good to go. Really impressed with the quick response.
