Looking for a smarter, energy-efficient way to heat and cool your home in Mississauga? You’ve probably heard of heat pumps — but what exactly are they, how do they work, and are they worth the investment?
In this guide, we’ll break down what a heat pump is, how it functions, the pros and cons, electricity usage, sizing, and even what makes a mini split heat pump a popular option across Ontario.
What Is a Heat Pump?
A heat pump is a dual-purpose HVAC system that provides both heating and cooling. Instead of generating heat like a furnace or traditional heater, a heat pump moves heat from one place to another using a small amount of electricity. In the winter, it pulls heat from the outdoor air and transfers it inside. In summer, it reverses and pulls warm air from inside your home and expels it outside, just like an air conditioner.
There are several types of heat pumps available:
- Air Source Heat Pumps (ASHP) – the most common for homes in Mississauga.
- Ground Source (Geothermal) Heat Pumps – pull heat from the ground.
- Mini Split Heat Pumps – ductless systems ideal for homes without existing ductwork.

How Does a Heat Pump Work?
Think of it like a reverse fridge. A heat pump uses a refrigerant cycle, involving components like a compressor, condenser, evaporator coil, and an expansion valve. It transfers heat from one area to another rather than burning fuel to create it.
In heating mode:
- The system extracts heat from outside air, even when it’s cold.
- The refrigerant absorbs this heat and is compressed to increase temperature.
- Warm air is then released into your home via an air handler or duct system.
In cooling mode:
- It pulls heat from the indoor air.
- The refrigerant absorbs and releases it outside, leaving your home cooler.
This efficient transfer of thermal energy is what makes heat pumps such a great option for year-round comfort.

What Are the Disadvantages of a Heat Pump?
Nothing is perfect, and heat pumps do have a few downsides depending on your situation.
- Upfront Costs: Heat pump systems are more expensive to install than furnaces or standard ACs.
- Lower Efficiency in Extreme Cold: While modern cold-climate models perform well, traditional heat pumps may lose efficiency in temperatures below -15°C. Many Mississauga homeowners pair them with a backup furnace.
- Installation Complexity: Ductless mini split systems need expert setup for optimal airflow.
- Electricity Dependence: Unlike natural gas, you’re relying solely on hydro power.
Good news: We specialize in cold-climate heat pump installations and offer furnace service options to complement your system.
How Much Does a Heat Pump Cost in Mississauga?
On average, you can expect to pay:
- $4,000 to $7,500 for air source systems
- $8,000 to $25,000+ for geothermal
- $3,500 to $6,000 for mini split heat pump systems
Cost depends on:
- System size and type
- Efficiency ratings (SEER, HSPF)
- Home insulation and size
- Installation difficulty
- Rebates and energy incentives
Don’t forget to check for Ontario energy rebates, which can significantly lower your cost.

How Much Electricity Does a Heat Pump Use?
Heat pumps are incredibly efficient. For every unit of electricity they consume, they can provide 2 to 4 units of heating or cooling — that’s a Coefficient of Performance (COP) of 2 to 4.
Monthly electricity usage depends on:
- Outdoor temperature
- System size and efficiency
- How well your home is sealed
- Usage habits
If you’re switching from an electric furnace or baseboard heaters, a heat pump could cut your hydro bill in half.
Pro tip: Combine your heat pump with a smart thermostat for optimal energy savings. We also offer smart thermostat installation.
What Size Heat Pump Do I Need?
This depends on your home’s:
- Square footage
- Insulation level
- Window size and type
- Orientation and shading
- Existing HVAC setup
A rough estimate is 20–25 BTUs per square foot, but only a licensed HVAC technician can perform an accurate Manual J load calculation.

- Basement suites or sunrooms
Each zone has its own air handler and remote control, offering:
- Energy savings (no duct losses)
- Personalized comfort
- Quiet operation
- Quick installation
