Sizing the new furnace
A furnace is sized to the heat the house loses. To pick the right unit, the technician looks over the rooms and insulation first instead of simply matching the old furnace.
Furnace Replacement and Installation in New Hampshire
Repair stops making sense when breakdowns keep coming, a heat exchanger has cracked or replacement parts are gone. At that point New Hampshire Heating arranges a new furnace, from the first phone call through installation.
Homes changing how they heat can get a new installation as well. Before you commit, your technician talks through the options that fit your house.
Replacement and installation
Fuel and venting
Oil, propane or natural gas, along with the venting method, decide what can be installed. A change in either brings extra work, and you hear about it from the start.
Removal of the old unit
When the old unit goes, it is disconnected and taken away. Where it makes sense, the replacement hooks into the ducts and fuel line already in place.
Other ways to heat
Certain houses may be better served by a heat pump, either alone or working with a furnace. The technician describes every route and does not steer you toward one.
Licensed technicians
New Hampshire’s Mechanical Licensing Board sets licenses for fuel gas installers and service technicians. For a gas furnace, we send licensed technicians. Ask for the license when yours arrives.
Frequently asked questions
Can you tell me by phone if I need a new furnace?
Not from a call alone. A technician has to look at the furnace, and booking that visit costs nothing.
It could be that fixing the current furnace is enough, which makes furnace repair the place to start. Our other services are all linked from the home page.
