Kelowna and the Okanagan are known for hot, dry summers — and a reliable air conditioner makes all the difference. Macdonald Mechanical installs and replaces central ducted air conditioners and ductless mini-split systems for homeowners across Kelowna, West Kelowna, Lake Country, Peachland, Summerland, Penticton, Vernon, and the surrounding Okanagan — with every installation sized correctly for your home and backed by a 10-year warranty.
Thinking About Cooling? A Heat Pump May Be the Smarter Choice
If your home also needs heating, a heat pump is worth serious consideration before committing to a standalone air conditioner. A heat pump provides efficient cooling in summer and heating in winter — all in one system — and currently qualifies for significant CleanBC rebates available to BC homeowners. A straight AC unit only cools, and there are no rebates available for AC installations.
We can walk you through both options during your free in-home assessment so you can make the best decision for your home and budget. Learn more about heat pump installation ›
Types of Air Conditioners We Install
Central Ducted Air Conditioning
The most common whole-home cooling solution for houses with existing ductwork. A central AC unit connects to your furnace's air handler and existing duct system to deliver cooled air to every room. If you already have a forced-air furnace, central AC is typically the most cost-effective cooling option.
Ductless Mini-Split Systems
The ideal solution for homes without ductwork, specific rooms, basement suites, or additions. A compact outdoor unit connects directly to one or more indoor wall-mounted units with no ductwork required. Mini-splits are highly efficient and allow for individual zone control — cool only the rooms you are using.
Getting the Size Right
Sizing an air conditioner correctly is just as important as the installation itself. An oversized unit will cool the space too quickly without running long enough to remove humidity, leaving your home feeling cold and clammy. An undersized unit will run constantly without ever reaching your set temperature.
Macdonald Mechanical performs a proper heat gain calculation for every installation, taking into account your home's square footage, insulation, ceiling height, window size, sun exposure, and the Okanagan's specific climate. You get a system that's right for your home — not just whatever happens to be available.

Frequently Asked Questions
What is the difference between central AC and a ductless mini-split?
Central AC uses your home's existing ductwork to distribute cooled air throughout the house from a single system. A ductless mini-split has no ductwork — an outdoor unit connects directly to one or more indoor wall units, making it ideal for homes without ducts, specific rooms, or additions.
Should I get an air conditioner or a heat pump?
If your home also needs heating, a heat pump is worth serious consideration. A heat pump provides both efficient cooling in summer and heating in winter — all in one system — and currently qualifies for significant CleanBC rebates in BC. A straight air conditioner only cools and there are no rebates available. We can walk you through both options during your free in-home assessment.
How long does an air conditioner installation take?
Most air conditioner installations are completed in one day. We will confirm the exact timeline during your free in-home assessment.
What size air conditioner do I need?
Sizing depends on your home's square footage, insulation, ceiling height, window size, and sun exposure. An oversized unit will short-cycle and leave your home feeling humid, while an undersized unit will run constantly without reaching the set temperature. Macdonald Mechanical performs a proper heat gain calculation to size your system correctly.
