A ductless mini-split system is an energy-efficient heating and cooling system that doesn’t require ductwork, making them ideal for older electrically-heated homes and/or homes with no ductwork. Also known as ductless heat pumps, they take advantage of the difference in temperature between outdoor and indoor air to heat or cool a room. The temperature can be adjusted through a wall-mounted console, remote control or smartphone app. Ductless units require only a very small hole to be drilled into an exterior wall, making them less vulnerable to air leakage and security problems.
Mini-splits also avoid the energy losses associated with ductwork, which can account for more than 30 per cent of the energy used to heat or cool indoor air.
What to Look For
- Choose an ENERGY STAR® certified ductless heating and cooling system to cut your electrical heating bill by up to 60 per cent, and your cooling bill by 30 per cent, depending on your climate.
Things to Consider
- Pair the system with a smart thermostat to better manage your home’s energy use.
- For installation, hire a professional heating and cooling technician who can determine the right product and size for your home and climate.
- Consider financing your home energy improvements through the City of Toronto’s Home Energy Loan Program (HELP).
- Get an EnerGuide home energy evaluation to help you understand how your home uses energy and identify all improvement opportunities.
- Check with your municipality, utility or retailer to see if rebates are available before you purchase.
$2,500 to $5,000+ per unit, including installation.
