Heating, cooling & everything in the mechanical room.
Residential HVAC for southern New Hampshire: repairs when it breaks, replacements when it's done, and the maintenance that keeps both of those rare.
Furnaces & boilers built for January.
Gas, propane, or oil — forced hot air or hot water — we service what's in your basement and replace it when it's time. Every install gets a combustion analysis and a full safety check before we call it done.
- Gas and propane furnace repair and replacement
- Oil, gas, and propane boiler service and installation
- Hydronic zoning: circulators, zone valves, and controls
- Thermostat and control upgrades
- No-heat emergency repairs, prioritized in winter
- Oil-to-gas and oil-to-heat-pump conversions
- Combustion analysis and safety checks on every startup
Central air that keeps up in a humid July.
New Hampshire summers are short, sticky, and hard on undersized equipment. We install and repair central air that actually pulls the humidity out — and we start the season with a proper charge check, not a guess.
- New central AC systems and condenser replacement
- Refrigerant leak diagnosis and repair
- Evaporator coils, capacitors, contactors, and blower motors
- Ductless cooling for rooms the ducts don't reach
- Humidity control and airflow balancing
- Pre-season AC start-ups and tune-ups
Cold-climate heat pumps, sized by the numbers.
A heat pump is only as good as the load calculation behind it. We measure the house, pick cold-climate equipment that keeps heating well below zero, and set it up with the right backup so the coldest week of the year is a non-event.
- Ductless mini-splits, single- and multi-zone
- Ducted heat pumps replacing an aging furnace or AC
- Hybrid / dual-fuel setups with your existing boiler or furnace as backup
- Manual J load calculation before any equipment is quoted
- Help identifying the NHSaves rebates your project qualifies for
- Heat pump service, coil cleaning, and repair
Tune-ups that keep you off the emergency list.
Most no-heat calls in January are a worn part that would have shown up in October. A seasonal tune-up is the cheapest HVAC work you'll ever pay for — and the only kind you get to schedule on your terms.
- Fall heating tune-ups: furnaces, boilers, and heat pumps
- Spring AC and heat pump service
- Combustion and safety checks, gas pressure, and venting
- Filter, coil, and condensate cleaning
- Startup readings recorded and left with you
- Honest heads-up on anything that's on its way out

Indoor Air Quality
New Hampshire winters dry a house out and seal it up at the same time. The fix is usually simple — if the ductwork is delivering what the system makes.
- Whole-home media and HEPA filtration
- Whole-home humidifiers for dry winter air
- Ductwork repair, sealing, and airflow correction
- Ventilation for tight, well-insulated homes
- UV and air purification options, explained without the hype
