Installation & Replacement

When you need your heating or air conditioning system replaced you can’t trust the project to just anyone. The cooling system has to be chosen, sized, and installed to handle your cooling needs. Too little or too much power from your AC system can mean inefficiency, poor air quality, and can even wear out your air conditioning system long before its time. With Callahan you’ll get prompt, professional service from our qualified technicians. 

Call (978) 689-9233 or contact us online to schedule a FREE estimate for your installation or replacement!
My furnace was working sporadically during the deep freeze of December 2017. The unit had been serviced by others in the past, but it took the tech at Callahan to discover the root of the issue. For the first time in 15 years, my furnace is working properly.

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.
