Dover, NH HVAC — Repair, Installation & 24/7 Emergency Service

Dover is the fastest-growing city on the Seacoast, and its housing shows both ends of that story: mill conversions and 1900s multifamilies around the Cocheco, and brand-new condos and single-families going up everywhere else. Each needs a different approach. Downtown condo with no room for ductwork? Ductless mini split. New construction with builder-grade AC that never quite kept up? Properly sized replacement. Century-old radiator house still on oil heat? We’ll keep it running, or quote a heat pump conversion when you’re ready.

Dover is one of our most-visited towns, minutes from our Somersworth base. Landlords and property managers: we handle multi-unit service calls and your tenants can call us directly. See everything we do, or check our other nearby coverage in Rollinsford, Durham, and Somersworth.

Can you install a mini split in a downtown Dover condo?

Almost always. Ductless systems need one small wall penetration and a spot for the outdoor unit — we’ve worked around HOA rules, shared walls, and tight mill-building layouts. Worth a phone call before you assume it can’t be done.

Do you do same-day service in Dover?

For emergencies, yes — we answer 24/7 and Dover is one of the closest towns to our base. For non-urgent work you’ll usually get a slot within a few days.

I own rental units in Dover. Can you handle tenant calls directly?

Yes. We work with several area landlords — tenants call us, you get the invoice and the report.
