Brian Chesney, and Why This Company Exists
Southern New Hampshire HVAC Services is one licensed tradesman with twenty four years in the trades, eight of them in HVAC, working out of Windham. The person who answers the phone is the person who does the work.

About
It started with a torch and an inspection gauge
Sixteen years went into welding, quality inspection and engineering before a single HVAC license. That work has a quality nobody in the trades forgets. A weld either passes inspection or it does not. There is no partial credit, no hiding it behind a panel, and no coming back in three years to explain why it opened up.
That is where the standard on every job here comes from. Every flare, every braze, every piece of pipe hanging in a basement gets the same eye a pressure vessel would have gotten. Done right the first time is not a tagline, it is a habit that took sixteen years to build.
Both sides of the fuel
Six years on the oil side taught the other half
Co-owning an oil company for six years covers a lot of ground fast. Burners, nozzles, pumps, tanks, deliveries, and what happens in somebody's basement in February when the tank ran dry on a Sunday.
It also showed how a fuel business looks at a customer, which is often as a contract that renews rather than as a family in a house. Learning both sides of that is a large part of why this company runs the way it does.


Licensed for both fuels
Eight years in HVAC, licensed for both fuels
The NH gas license, GF1910596, covers natural gas and propane. The NH oil heating technician license, HT2300476, covers oil fired equipment. EPA Section 608 certification covers refrigerant, which every mini split, heat pump and air conditioner depends on.
Southern New Hampshire is split between gas, propane and oil, sometimes street by street. Holding all three means the fuel in your basement is never a reason to call somebody else, and it is a fair question to ask any contractor you are considering.

Home
Windham, three kids, and New England winters
This is a family business in the ordinary sense of the phrase. A husband and a dad of three living in Windham, working on houses in Windham and the towns around it, and driving home to the same weather everybody else is dealing with.
That is also the reason the emergency line is real. A house with no heat at eleven at night in January is not an inconvenience, it is a family sitting in coats waiting for somebody to answer. Somebody answers.

Licenses and certifications
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
All three are issued to Brian Chesney personally and can be verified with the State of New Hampshire and the EPA.

Four things you can count on
You see what I see
The panel comes off and you get shown the actual problem. A homeowner who understands what failed makes a better decision than one who is handed a number.
Repair comes first when repair is right
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.
You hear the price before the work starts
Upfront, in plain words, including on an emergency call at midnight. Nobody should be finding out what a repair cost after it is finished.
The same person, every time
One phone number, one technician, and somebody who remembers what your system looked like last year. That is the whole reason this business exists.
One truck, one technician
What working with a one man company actually looks like
The honest version, because the size of this company changes how a job runs and you should hear that before you book one.
- Planned work is booked around the season
- Call and ask, because the honest answer changes with the season. Installations and cleanings book further out during the autumn heating ramp than they do in spring, which is exactly why a cleaning booked in August beats one booked in December.
- A multi day job keeps the same person on it
- A boiler changeout or a multi zone mini split install runs across more than one day. One truck and one licensed technician means the person who starts it is the person who finishes it, and the person who comes back next year already knows what is in your basement.
- Emergencies come first, every day of the year
- A house with no heat in January moves to the front. That is the trade a small company makes, and it is the reason the service area is deliberately tight enough to actually get there.
- The price is agreed before the work starts
- Estimates on installations and replacements are free. On a repair, you hear the number before anything begins, including on a call at midnight.
- Monday to Friday, 7:30am to 4:00pm
- Emergency service 24 hours a day, every day of the year

That is the whole company
One truck, one licensed tradesman, and a service area small enough to answer the phone at two in the morning. If that is the kind of contractor you were looking for, get in touch.
