Ductless comfort for every room of your home.
Mini-splits deliver quiet, energy-efficient heating and cooling exactly where you need it — perfect for additions, condos, and rooms your ductwork never reached, right across Durham Region.
Year-round comfort, no ductwork required.
Not every home has ductwork — and not every room gets comfortable even when it does. Ductless mini-splits deliver quiet, efficient heating and cooling exactly where you need it, without tearing into walls. Air Comfort Guys installs and services ductless systems for homeowners across Whitby, Oshawa, Ajax, Pickering and the rest of Durham Region.
They’re ideal for additions, finished basements, condos, sunrooms and older homes — anywhere a central system falls short. One outdoor unit can run multiple indoor heads, so you can zone your comfort room by room and only heat or cool the spaces you’re actually using.

Four ways to bring comfort to any room.
Every ductless setup uses one or more indoor “heads.” The right style depends on the room and how it’s built — here’s how they compare.
Wall-mount
The most common and cost-effective option. Mounts high on the wall and blends into almost any room.
Floor-mount
Sits low like a radiator — ideal where high wall space is limited or ceilings slope, like attics and additions.
Ceiling cassette
Recesses into the ceiling for a nearly invisible look, spreading air evenly from above.
Multi-zone
One outdoor unit runs several indoor heads, each with its own control — comfort tailored room by room.
Answers before you call.
How much does a ductless mini-split cost in Durham?
A single-zone ductless system typically runs from about $4,000 to $6,500 installed, depending on the unit and your space. Multi-zone systems that cover several rooms cost more, based on the number of indoor heads. We give you an exact, upfront quote after a free in-home assessment.
Do ductless mini-splits work in Ontario winters?
Yes. Modern cold-climate mini-splits are built to heat efficiently well below freezing, and many keep working through the coldest Durham weather. During your estimate we’ll recommend a system rated for our winters so you stay warm all season.
Can one ductless system heat and cool my whole house?
It can. A multi-zone system connects one outdoor unit to several indoor heads, each with its own control — so you can heat and cool multiple rooms independently. For larger homes we’ll size the system to cover the spaces you use most.
Are ductless mini-splits noisy?
No — they’re one of the quietest options available. The loud part, the compressor, sits outside, and the indoor heads run at a soft whisper, quieter than a typical fridge. Most people barely notice them running.
Are ductless systems eligible for rebates?
Many high-efficiency ductless and heat-pump systems qualify for rebates, but programs change often. On qualifying systems we’ll tell you exactly what you can claim — and how — before you commit, so you never miss the savings.
Do you offer financing on ductless systems?
Yes — flexible monthly payment options are available on qualifying installations, subject to approval. We’ll walk you through the real terms during your estimate so you can choose what fits your budget.
