Exeter NH Plumber, Mini Splits & Gas Fitting

Exeter's downtown is a museum of American housing: Federals and Greek Revivals off Front Street, converted two-family homes near the Squamscott, and academy-adjacent properties where nobody is allowed to touch the facade. Almost none of it has ductwork, and a lot of it is still on oil or an aging gas boiler in a stone-walled cellar. That is the exact job ductless mini splits were invented for, and it is why Exeter work is mostly careful routing: where the lineset goes, how the condenser sits, what the neighbors and the historic district will accept.

Older Exeter houses hide their shutoffs. If a supply line lets go at 2am, call rather than hunt for a valve. The emergency line is answered around the clock.

FAQ

Can you install a mini split in an Exeter historic district home?

Yes, and the routing is the whole conversation. We place condensers off the primary elevation, run line-hide that follows trim lines instead of cutting across clapboard, and talk through the plan before anything is drilled. If your property has review requirements, we work to them.

We still heat with oil. Is switching worth it in Exeter?

Usually, and the honest answer depends on your oil price and how many zones you need. We size the heat pump for a real New Hampshire winter, keep your boiler as backup where that makes sense, and show the crossover math in your estimate rather than promising a number.

Do you do gas fitting in Exeter?

Yes. We hold New Hampshire gas fitting licensure, which means gas piping, meter-to-appliance runs, and conversions are done by the same shop that sets the equipment, not subbed to a second contractor with a second schedule.
