There is no shortage of ways to make a home more comfortable in a Quebec summer. A steady temperature, controlled humidity and cleaner air are all within reach, for a single room or for the whole house. Choosing well comes down to two questions: does your home already have air ducts, and do you want the system to heat as well as cool? Here are the three cooling solutions Quebec homeowners choose most often.
If you already have ducts, and want heating too: a central heat pump. If your home has a forced-air heating system, the ductwork for cooling is already in place. A team installs the outdoor unit and connects it to those ducts, and cooled air reaches every room through them. This suits large homes and anyone who wants to avoid temperature swings from one room to the next. Because a central heat pump also heats, it can run in winter alongside your existing system or replace it outright, and that dual role is what makes it the option most rebate programs are built around. If you are weighing a heat pump against straight air conditioning, our comparison of the two goes through the trade-offs in detail.
If you have no ducts, or want room-by-room control: a ductless mini-split. In a condo, in a home without ductwork, or where you want to set each room’s temperature independently, a ductless system is the practical answer. It pairs an outdoor unit with one indoor head (mono-split) or several (multi-split). The indoor heads are wall-mounted and more visible than a central system’s vents, but installation is far less invasive, the price is lower and upkeep is straightforward.
If you only want cooling: central air conditioning. As with a heat pump, central air conditioning makes sense when you already have a forced-air system. The difference is that here you keep the heating you have and simply add cooling to it. The existing ducts do the distribution, and only a condensing unit goes outside. It is the least expensive route to whole-home cooling, and nothing about the interior of the house changes.
Central or multi-zone: the four things that decide it. Once you are down to those two, here is what separates them. Ducts: central air conditioning needs an existing duct system, and adding one to a house without it is the single biggest cost in the project, while a multi-zone system needs only a line between the outdoor unit and each indoor head. Control: central cooling gives you one temperature for the house; a multi-zone system sets each room independently, and cooling only the rooms in use shows up on the electricity bill. Noise: the central unit is usually tucked away, so it is the quieter of the two, where wall-mounted heads sit in the room with you. Appearance: central cooling is invisible apart from the vents, while indoor heads are on the wall. A multi-zone system pairs one outdoor unit with anywhere from one to six indoor heads, so it scales to most homes.
What rebates you can still claim. Program names keep circulating long after the programs themselves close, so it pays to be precise. LogisVert, from Hydro-Québec, is the active program for efficient heat pumps, and it is generous enough to change the maths between a heat pump and a straight air conditioner. Two others are often quoted but no longer available: Chauffez vert ended on 31 March 2026, and the Canada Greener Homes Grant stopped taking new applications in February 2024. Our guide to government HVAC grants in Quebec sets out what each active program covers, and our grants and subsidies page lists what we are currently helping customers claim.
If you are still weighing the options, ask someone who installs all three. Our advisors will look at the ductwork you already have, the heating system you are working with and the way you actually use your home, then tell you which one fits. We install and service every option on this page, with air conditioners and heat pumps from the leading brands. Get in touch and we will help you narrow it down. Once you know which type you want, our air conditioner buyer’s guide covers what to check before you sign.
