Overview

The Mitsubishi M-Series GL is the world's best-selling ductless mini-split — trusted by millions of homeowners for reliable, energy-efficient cooling and heating. No ductwork required. Wall-mounted indoor units connect to a compact outdoor compressor, delivering precise room-by-room comfort.

Key Features

Simple, Clean Installation
A small 3-inch hole connects the indoor and outdoor units via refrigerant lines. No ductwork, no major renovation. Most single-zone installations are completed in under a day.
Slash Energy Bills by 30–50%
Heat pumps move heat rather than generate it, delivering up to 4× more energy than they consume. Homeowners switching from gas furnaces or electric baseboard see dramatic savings.
Whisper-Quiet Operation
Indoor units operate as low as 19 dB(A) — quieter than a library. The outdoor unit runs at conversation-level volume. No furnace roar, no ductwork rumble.
Zone-by-Zone Comfort
Multi-zone configurations connect up to 8 indoor units to one outdoor compressor. Each room gets its own thermostat — no more fighting over temperature settings.
Greener Homes Rebate Eligible
Qualifies for the Canada Greener Homes Grant and provincial heat pump rebates. Combined incentives can reach $5,000–$10,000+. H&C handles all the paperwork for you.
7-Year Compressor Warranty
Mitsubishi backs the M-Series GL with a 7-year compressor warranty and 5 years on parts when professionally installed. H&C handles all warranty registration for you.

Perfect If You're Looking To…

Add efficient cooling and heating to any room — without running ductwork. Cool a hot bonus room, heat a basement suite, or upgrade from noisy window units. The GL handles it all with whisper-quiet efficiency.

The World's #1 Selling Mini-Split Brand

50+ Years of Innovation

Mitsubishi Electric has been building heat pumps since the 1960s. The H2i Hyper-Heating technology was specifically developed for markets like Canada and northern Japan where winter performance is non-negotiable.

Professional Installation

H&C's licensed technicians are trained on Mitsubishi systems. Proper refrigerant charging, line set sizing, and placement are critical — we get it right so your system performs as rated.

Financing Available

Flexible payment options make the switch to heat pump technology affordable. Ask about our low monthly payment plans — combine with government rebates to reduce your out-of-pocket cost even further.

Not Sure Which Size
Is Right for Your Home?

Sizing a ductless system correctly is critical — too small and it can't keep up on the hottest days, too large and it short-cycles and leaves rooms humid. Our licensed technicians perform a free load calculation and recommend the right configuration for your space.

Frequently Asked Questions

Can a ductless system heat my room in winter?
Yes — the M-Series GL provides efficient heating down to about –8°C. For moderate Ontario winters and supplemental heating, it works very well. In extreme cold, it's best paired with a backup heat source. For primary heating in deep cold, consider the FS Hyper Heat model.
How much can I save on energy bills?
Heat pumps are 3–4× more efficient than electric baseboard and significantly more efficient than a gas furnace in most conditions. Most homeowners switching from gas see 30–50% savings on heating costs. The savings are even larger if you're replacing electric baseboard or an oil furnace.
What's the difference between the GL Standard and the FS Hyper Heat?
The GL Standard is designed for moderate climates and is ideal as a cooling-primary system with supplemental heating. The FS Hyper Heat uses Mitsubishi's H2i® technology to maintain full heating capacity in extreme cold — the right choice if you need a ductless system as your primary heat source.
Do I need ductwork for this system?
No — that's the whole point. The GL mounts on your wall and connects to the outdoor unit via a small refrigerant line through a 3-inch hole. No ducts, no major construction. It's the simplest way to add cooling and heating to any room.
What government rebates are available?
The Canada Greener Homes Grant offers up to $5,000 for heat pump installations. Ontario also has the Home Efficiency Rebate Plus program. Combined with utility rebates, total incentives can exceed $10,000. H&C handles all paperwork and will advise you on every rebate you qualify for.
How long does installation take?
A single-zone GL installation is typically done in 4–6 hours. Multi-zone systems take a full day or two. H&C handles everything: wall mounting, refrigerant lines, electrical, condensate drainage, and system commissioning.
