Londonderry NH Heating and Cooling, Built for Propane and Oil Country
Yes, Londonderry is covered. It borders Windham to the northwest, and it is a town where most houses run on propane or oil rather than natural gas, which is exactly the dual license case.

Londonderry, NH
What the houses in Londonderry are actually running
Londonderry sits northwest of Windham, past the orchards, running up toward the airport and Exit 5.
Londonderry is large lot suburban. Big 1990s and 2000s colonials on an acre or more, most on well and septic, spread out across what was orchard land not that long ago.
Natural gas is limited outside a few corridors, so the town runs heavily on propane and oil. Tanks, burners and fuel deliveries are a normal part of the conversation here.
Almost every one of those colonials has a bonus room over the garage, and almost every one of those bonus rooms is the hottest room in the house in July and the coldest in January. It is the single most common ductless job in this town.
Proximity to Manchester Boston Regional Airport and the Woodmont side keeps the housing stock turning over, which means a steady stream of pre sale inspections turning up aging equipment.

What comes up most
Londonderry calls, and what they usually need
Londonderry is bonus room and propane country. Ductless for the room the ductwork never reached, and dual fuel fluency for everything in the basement.

Questions that come from this town
- The room over my Londonderry garage is unbearable. What fixes it?
- A single ductless head, almost every time. Rooms over garages have exterior exposure on five surfaces and are usually at the tail end of a duct run that was never sized for them. Adding one mini split head solves both the summer and the winter problem without re engineering the whole system.
- Do you work on propane systems?
- Yes. The NH gas license GF1910596 covers propane as well as natural gas, which matters in Londonderry because most of the town is on propane rather than a gas main.
- Can a heat pump replace propane heat in a Londonderry colonial?
- Often, and the numbers are usually more favourable against propane than against natural gas. Whether it makes sense depends on the age of your current system, how the house holds heat, and what you want for backup on the coldest week. You will get the arithmetic laid out both ways rather than one recommendation.
