Trusted New England HVAC Experts Since 1989
Since 1989, N.E.T.R., Inc. has been the trusted local expert for residential and commercial HVAC solutions throughout New England. Our deep roots in the community mean we understand the unique challenges of heating and cooling homes in this region—from historic brownstones in Boston to coastal homes in Maine. We are committed to providing reliable, energy-efficient comfort to our neighbors in Massachusetts, New Hampshire, and Maine.
As New England’s #1 Mitsubishi Electric Ductless Installer, we specialize in designing and installing high-performance ductless heating and cooling systems. Our status as a Mitsubishi Diamond Elite Contractor is the highest level of accreditation available, ensuring you receive extensively trained technicians, superior installation quality, and an exclusive 12-year warranty on parts and compressors.
Why Choose a Local New England HVAC Expert?
New England’s climate is demanding, with hot, humid summers and frigid winters that put immense stress on any HVAC system. Furthermore, the region’s diverse and often historic architecture presents unique installation challenges that require specialized knowledge.
- Understanding Older Homes: Many New England homes lack existing ductwork, making ductless mini-splits an ideal solution for adding air conditioning without compromising historical character.
- Tackling Humidity: High summer humidity is a major comfort issue. We design systems that not only cool but also effectively dehumidify your space.
- Cold Climate Performance: We specialize in cold-climate heat pumps, like Mitsubishi’s Hyper-Heat technology, that provide reliable and efficient heating even on the coldest winter days.
Our certified technicians have the local experience to create a custom solution that guarantees year-round comfort and efficiency for your specific property.
