Sound familiar?
Rooms your current system just doesn’t reach
A basement finish, a garage conversion, a sunroom, an addition, or just one room that’s always too hot or too cold — if it’s not comfortable today, there’s a good chance a single ductless zone fixes it.
- Finishing your basement into a rec room, home gym, or office
- Adding a guest suite, in-law space, or bedroom your ducts don’t reach
- A garage, sunroom, or addition that’s too hot in summer, too cold in winter
- Tired of a noisy window AC or space heater in one room
- Already have ductless comfort upstairs — ready to extend it downstairs
- A finished space that’s unusable half the year without help
Why ductless
One small system, done right
A ductless heat pump adds heating and cooling to a single room or zone without tearing into walls or extending ductwork that was never designed to reach it. Here’s what that gets you:
- No ductwork to install or extend — one small line set does the job
- Heats and cools from a single system, no separate units to run
- Actively dehumidifies, so basements stay dry instead of musty
- Whisper-quiet indoor units — nothing like a window AC
- Cold-climate rated equipment, built to perform in New England winters
- Zone control — heat or cool just that room without touching the rest of the house

3 Questions Worth Asking Any Installer
A heat pump is only as good as the install behind it. Before you choose on price alone, here's what separates a system that lasts from one that doesn't — and exactly where we stand.
Ask your installer
“Will a licensed electrician do the wiring — and will you pull an electrical permit?”
A heat pump needs a dedicated circuit and real electrical work. Many installers skip the licensed electrician or never pull the permit — which can mean failed inspections, insurance and resale problems, and a real safety risk.
Our standard: Licensed electricians and pulled permits on every job — done to code and inspected.
Ask your installer
“How do you evacuate the lines — and to what level?”
The install matters more than the brand on the box. The single biggest factor in how long a heat pump lasts is a proper evacuation — pulling every bit of moisture and air out of the refrigerant lines. Skip it and trapped moisture turns to acid that eats the compressor, failing a system in a few years instead of 15–20 (and it can void the warranty).
Our standard: Nitrogen purge while brazing, a pressure test, then a deep vacuum to 500 microns or lower — verified on a gauge. Non-negotiable on every install.
Ask your installer
“Did you run a real heat-load calculation, or guess from square footage?”
Equipment that's too big short-cycles — hot and cold spots, higher electric bills, and a lost rebate. Too small can't keep up on the worst days. The right size does both jobs and keeps your running costs down.
Our standard: An accurate heat-load calculation, sized to 90–120% — quality, affordable equipment matched to your home so your electric bill stays under control.
Anyone can sell you a box. We engineer the whole system.

Basement, Bonus Room & Zone Add-On FAQ
No. A ductless system runs a small line set from an outdoor compressor to one indoor unit — no ducts to add or extend, so it works in basements, additions, and rooms your current system was never connected to.
Yes. The same system that heats and cools also dehumidifies as it runs, which is a big part of what makes a basement more livable year-round.
Most single-zone installs wrap up in a day or two.
Most Massachusetts homeowners qualify for an instant $650 credit per outdoor unit (up to two per address) through the New England Heat Pump Accelerator — a separate program from Mass Save®. It’s applied directly on your invoice at the time of purchase, no application required.
No. A new zone runs on its own outdoor compressor and indoor unit, completely independent from what you already have — it won’t touch or interfere with your current system.
No. The same setup works for a bonus room, garage conversion, sunroom, home addition, or any single room your current system doesn’t reach.
No. Ductless indoor units run far quieter than a window air conditioner or space heater.
