Newmarket Heating & Cooling — From the Mills to the Bay

Newmarket packed a lot of different housing into a few square miles. The converted mills along the Lamprey have the same story as mill buildings everywhere: great space, no ductwork, and rooms that run hot on the sun side and cold on the river side. Ductless mini splits solve all three at once — zoned heat and AC, room by room, without opening a single wall. Meanwhile the newer neighborhoods out Route 108 have conventional forced-air systems we repair, replace, and tune like anywhere else.

Being near Great Bay also means humidity — summer air here is heavy, and a right-sized cooling system matters more than a big one. We size to the building — sometimes the smaller unit is the better call. We also cover Durham next door, Dover, and Portsmouth. Full offerings on the services page.

Can you install AC in a mill building apartment?

Usually yes — mini splits need only a small line-set penetration and somewhere to put the outdoor unit. Condo and HOA rules vary, so we’ll help you figure out what your building allows before anyone commits to anything.

One room roasts, the next one freezes. Fixable?

That’s a zoning problem. With a mini split, each indoor head runs its own temperature, so both rooms get what they need.

How far is Newmarket for you?
