Windham, New Hampshire ยท Licensed for gas and oil
Windham NH Heating & Cooling. Repair First, When Repair Is Right.
Brian Chesney answers the phone, and Brian Chesney is the one who shows up. Mini splits, heat pumps, boilers, furnaces and central air, installed clean and repaired right, with a straight answer on whether your system needs replacing or just needs fixing.
Checkable, not claimed
Three numbers you can look up
Most contractors list badges. These are license numbers, they belong to a person rather than a logo, and the State of New Hampshire will confirm every one of them.

GF1910596
NH Gas License
Licensed by the State of New Hampshire to work on natural gas and propane appliances, including boilers, furnaces and wall hung units. You can look the number up.
HT2300476
NH Oil Heating Technician
Licensed for oil fired heating equipment, burners and oil tanks. Southern New Hampshire runs on both fuels, and plenty of contractors are licensed for only one.
Certified
EPA Section 608
Federally certified to handle refrigerant, which is what every mini split, heat pump and central air system runs on. It is required by law, and it is worth checking.
Fully insured
Licenses issued by the New Hampshire Office of Professional Licensure and Certification. Fully insured.

Repair or replace
Sometimes the honest answer is that you do not need a new system.
If a unit is able to be repaired and if doing so is cost effective for the customer, then a repair will be our first recommendation.
Homeowners around here compare three and four quotes on a boiler and pick the one that felt honest, not the one that came in cheapest. There is a reason for that. The stories that circulate in this area are about five figure replacement quotes written against systems with years of life left in them.
A twenty year old boiler is not automatically a boiler that needs replacing. A great many of those quotes are answered by a circulator, an aquastat, an ignition module or a good cleaning. When it genuinely is time, you will hear that too, with the reason and with the panel open so you can see the same thing.
Show the work
Drag the handle. That is the same coil.
Nobody in this county puts their work on their website. That is a strange thing about a trade judged entirely on craft, so it gets fixed here. Every pair on this site is a real job.


Same coil, same visit. A season of leaf litter, seed debris and road grit packs the fins solid, the system runs at high head pressure all summer to move the same heat, and the electric bill goes up every month while the compressor works harder than it was built to. This is what a yearly cleaning is actually for.

Who shows up
Twenty four years in the trades, and the last eight of them in HVAC
Sixteen years welding, inspecting and engineering came first. That is where the standard comes from, because a weld either passes inspection or it does not. Six years co-owning an oil company came next, which is where the fuel side and the tanks were learned.
SNH HVAC Services exists so that the person who answers the phone is the person who walks into your basement. One phone number, one licensed technician, and one truck in the driveway every time.
The owner is the technician, and he will show you the work.


Reviews

This is a young business run by a tradesman who is not. Reviews get posted on this site as customers leave them, with real names and real towns. Until then, the license numbers above are the proof, and every one of them is checkable.
