Residential & Commercial HVAC for Plaistow

Heating & Cooling Services We Provide
New Hampshire winters are long and cold, and summers bring real humidity and heat. Your home or business depends on systems that work in both directions, and we're set up to handle either.
Heating Services:
We repair, install, and replace furnaces, boilers, and heat pumps for both residential and commercial customers. Heat pumps move heat rather than generate it. This means they use less energy than systems that burn fuel to create warmth, making them an efficient option for year-round comfort. If your heating system is failing, aging, or due for replacement, we can assess what's there and recommend the right path forward.
Cooling Services:
We repair and install central air conditioning systems and ductless mini splits. Mini splits are a practical solution for homes with boilers and no existing ductwork. They deliver both heating and cooling without major renovation. Whether you're replacing an aging central system or adding cooling to a space that never had it, we handle the installation from start to finish.
HVAC Maintenance & Tune-Ups:
Annual maintenance can help reduce the risk of breakdowns during peak-demand months. Our technicians inspect the system, identify developing issues, and perform the adjustments and minor repairs needed to keep things running. Scheduling a tune-up before the heating or cooling season is a straightforward way to stay ahead of problems.
