Had Callahan install a mini split pack for A/C in my upstairs bedrooms this spring. They were prompt, efficient, and did a great job. Then when my main boiler went out a few weeks later and the guy who installed it was too busy to do repair work anymore, Callahan came out and saved my bacon, addressing multiple serious failures and restoring the hot water and downstairs heat immediately. Love these guys!

I am a builder / developer in the Lakes Region NH area and it has been tough finding good subcontractors due to the volume of work and the availability of trades in the area. We had a project in our Residential Division with a short completion deadline. We contacted Callahan A/C & Heating and Chris, Joe and their team stepped up to the plate and got in and completed their work as promised. I will definitely consider using there services again in the future.

During our search for a replacement AC system, we called Callahan HVAC out of Moultonborough, NH. From the time that we called them until the job's completion, they were very responsive, professional, and patient with all of our questions. Every item that was discussed on the original quote was completed on time, within budget and met all our expectations.

The installation team took the time to explain all of the details of the job and offered many times to answer any additional questions. Once the job was completed, they made sure that they cleaned up in every area that they were working. If you have HVAC needs, I highly recommend you give them an opportunity to help you. We're glad we found them. Great group of people.
