In Mont Vernon, ductless mini-splits are popular for older homes, additions, and zoned comfort, while heat pumps can also be installed as central systems connected to existing ducts.

The guys at Brookside did top notch work replacing our 24 y/o Weil-McLain. Dropped off the new Buderus unit and HTP tank on Tuesday, came back on Wednesday and had everything installed and the old unit removed by the time I got home from work. Easy process start to finish.

First person I hired to do work on my new home in NH. Great company. My 1st service call was the owner. Extremely professional and personable. Called to check on us a day later to make sure we were operating to standard. I highly recommend this company.

Go figure...my furnace decides to stop working as soon as the temperatures drop. I called this company, left a message with the call center, received a call back within a couple of hours, and an appointment was booked. The two gentlemen that came to service my furnace were super nice, and they even gave my dog the attention he so desperately craves every time he sees a human. Definitely recommend!

We've used Brookside to replace our HVAC this past summer and our oil furnace this month. They do what they promise and always have the best prices. We've suffered with bad ductwork in this house for 5 years. We're now enjoying even, toasty heating. And summers are cool and quiet! I highly recommend BROOKSIDE!
