Why install a heat pump?
Comfort that thinks ahead.
We don’t just install a Heat Pump; we give it a brain. With GENN, your system is monitored 24/7 to ensure peak performance. While other systems wait for a breakdown to get attention, GENN identifies issues before they happen, alerting our team proactively. It’s the perfect blend of high-efficiency hardware and always-on intelligence.
Smarter energy. Bigger savings.
We install advanced heat pump systems that adapt to your home’s needs — using only the energy required to keep each room comfortable. They can be up to 160% more efficient than traditional furnaces, helping you cut energy costs without compromising comfort.
A cleaner way to heat and cool your home.
Our all-electric installations run without burning fuel, which means cleaner air and fewer emissions. It’s a practical way to make your home more sustainable while staying warm in winter and cool in summer.
Built for every season in Massachusetts.
We install high-efficiency systems designed to perform even in harsh New England winters. From freezing days to humid summers, your home stays comfortable all year long — with one system that does it all.
Always comfortable — no adjustments needed.
Smart changeover technology automatically shifts between heating and cooling as the weather changes. You stay comfortable without ever touching the thermostat.
