Heat Pumps in Londonderry, NH
Dave's Ductless HVAC installs cold-climate heat pumps across Londonderry, New Hampshire. Much of the town went up between the late sixties and the eighties, which means a lot of split-levels and raised ranches carrying original ductwork or none at all. That vintage is the single biggest clue about what a heat pump project here will involve.
Local planning
Londonderry's housing stock decides most of the answer
A Londonderry house tends to tell you what it needs before anyone opens a catalogue. Split-levels put half the living space over an unconditioned garage, raised ranches push heat upstairs and leave the lower floor cold, and additions from the eighties often hang off a system that was never resized for them. I look at where the floors change level and where the original system stops reaching, because those two things predict the uncomfortable rooms almost every time. The equipment conversation comes after that. Londonderry is Rockingham County, so the same NHSaves programme conditions apply here as in the towns either side of it.

Londonderry questions
Straight answers for Londonderry
My Londonderry split-level has a cold lower floor. Is that a heat pump problem?
It is usually a distribution problem that a heat pump can solve well. A room over a garage or below grade loses heat differently to the rest of the house, and giving that zone its own control is often more effective than pushing the whole system harder.
There is ductwork already. Does that mean ducted is automatic?
No. Existing ducts are worth having, but the question is whether they can carry the airflow a heat pump needs at the temperature it delivers. That gets measured rather than assumed, and sometimes the honest answer is a mix of ducted and ductless.
Does the eighties addition need its own system?
Often it needs its own zone rather than its own system. Additions are the most common place I find a room that the original equipment was never sized to reach.
