Cool Any Room with Precision Ductless AC Installation
Durham homes keep adding rooms the main ductwork was never meant to reach, the converted space above the shop, the finished walkout basement, the back sunroom overlooking the river. Durham Heating & Cooling installs ductless mini-splits that bring proper heating and cooling to those spaces without opening walls. We size each unit to the room, run the line sets clean, and mount everything level, whether the building is a century village home or a farmhouse out toward Mount Forest.
Why Homeowners Call Us
Adding a room the existing ducts never reached?
Home offices, finished basements, and back sunrooms in Durham, we install ductless mini-splits sized to the space with clean line sets and no new ductwork.
Right BTUs for the Actual Room
Spec too big and the head short-cycles, leaving the air cool but clammy. We size the capacity to the actual room, whether that is a small bedroom in a century village home or a great room in a farmhouse build out by Walkerton.
Line Sets Tucked Away, Penetrations Sealed
The outdoor unit sits level on a pad that drains, the line sets run hidden, and every penetration is sealed. We treat your home, new or old, the way we would treat our own.
One Unit, Year-Round Comfort
A cold-climate mini-split still harvests warmth from outdoor air deep into a Durham January, so one quiet head carries your home office or addition through bitter cold and August humidity alike.
FAQ
Ductless AC Installation in Durham: Common Questions
How much does ductless AC installation cost?
Every quote covers equipment, mounting, line sets, electrical coordination, and commissioning, with no hidden line items. Book a free assessment and we will put real numbers in writing.
How long does a ductless AC installation take?
Spring and early summer slots go quickly, so book four to six weeks ahead if you want cooling before the first heat wave hits your street.
Should I repair or replace my mini-split?
Think in seasons, not parts. When one more repair only buys one more summer, that money is better put toward a properly sized replacement that also heats in winter.

What Durham Homeowners Say
Real feedback from neighbours we've helped stay comfortable year-round.
“AC was struggling through a humid week. They found a bad capacitor, replaced it, and never tried to sell us a whole new unit.”

“Cleaned years of dust and harvest dirt out of our ductwork and the house feels noticeably less stuffy. Genuinely tidy crew throughout the whole job.”
