Why Choose Endless Energy
Trusted by the experts, and the community
01
With over 40 years of operating as a proudly independently owned business, Endless Energy is in this with you for the long haul.
We are proud to be top-level partners with the manufacturers for most of the equipment we install, This means our customers get access to extended warranties (including up to 12 years on all heat pump installations), superior customer service, and cutting-edge products with brands including Mitsubishi, LG, Daikin, and Bryant. Plus, we provide all heating and cooling consultations completely FREE to you!
Additionally, we never sub out our work. Our expert team of local HVAC and plumbing technicians, insulation teams, home energy auditors, licensed electricians and more handles everything in-house! Plus, we were an early Home Performance Contractor with Mass Save®, and our staff are well experienced at navigating rebate and heat loan processes. Add to that an A+ rating with the Better Business Bureau, Torrco 2022 Partner of the Year Award, 2024 and 2025 Nextdoor Neighborhood Fav Awards, Diamond Contractor with Mitsubishi, Platinum Pro Dealer with LG, our selection as a 2025-2026 Ductless All-Star by the Ductless Directory…and it’s easy to see why we’re a top local pick.
One stop shop, all in house
02
When you call our offices, you will always be speaking with an Endless Energy employee, not an oversees firm. If you need a Mass Save® Home Energy Assessment to qualify for the HEAT Loan or Mass Save heat pump rebates, that will be performed by an Endless Energy energy specialist in our Mass Save division. If you need plumbing work, that will be completed by one of our on-staff licensed plumbers. At Endless Energy, every piece of the puzzle is put together in house, because we know it’s the only way to ensure top quality service from start to finish.
Rebates up front
03
Last but definitely not least, Endless Energy is one of the only HVAC companies that, when eligible, provides Mass Save heat pump rebates to customers as instant, up front rebates. You read that right. That means instead of having to wait months on end to be paid back for rebates you’ve qualified for, we cover that part of the project cost until the rebates are paid out.
