- Heat pumps are highly efficient, offering cooling in summer and heating in winter. They are effective even in colder climates, which is crucial for cities like Toronto that experience significant winter cold.
- The number of heat pump installations in Canada has increased from 400,000 to 850,000 over the last 20 years. Heat pumps are shown to be the lowest-cost option for most households over the lifetime of the system, despite higher upfront costs.
Heating, Ventilating, and Air-Conditioning (HVAC) Systems
The HVAC system remains the most common and popular choice for condo climate control. These comprehensive systems maintain desirable interior conditions by regulating air quality, moisture content, and temperature throughout the unit.
HVAC systems work by using radiators or air systems to supply heat and warm the air within condo units. They ensure proper ventilation by maintaining pure, fresh air circulation while removing exhaust fumes and stale air.
Types of Heating Systems in Apartments
| System Type | Best For | Advantages | Disadvantages |
|---|---|---|---|
| Centralized | Large buildings | Easy temperature control, greater load capacity | Higher installation and maintenance costs |
| Packaged | Space-limited buildings | Combined heating/cooling, space-efficient | Limited customization |
| Individual | Smaller buildings | Unit-specific control | High maintenance in large buildings |
1. Centralized Systems
A central system is a single unit that meets all of the building's HVAC requirements. These are combined assemblies that often utilize water as a cooling medium and different pipework to circulate air.
This allows the property managers to control the temperature easily. In addition, it has a greater capacity for load management. However, they involve higher costs for installation and proper maintenance.
2. Packaged Systems
These are frequently employed in buildings when there isn't enough space for independent apparatus. They combine heating and cooling into a single unit. The following components are commonly seen in packaged systems:
- In a sole unit, the heat pump couples with the fan coil.
- Control/Thermostat connector for total system management.
- Air quality enhancers are available as an option. UV lamps, ventilators, cleaners and filters clean the air until it circulates around the building. So, you get fresh air circulation in the room.
3. Individual Systems
Also known as decentralized power systems, these use numerous isolated units in different spots across a building to provide electricity.
This HVAC system might need acute maintenance in large or high-rise apartment buildings if multiple apparatus are spread throughout the structure. Thus, it is critical to centralize systems that are prone to breaking or leaking and need excessive replacement costs.
Comprehensive Condo Heating System Available in Canada
HVAC can produce heat by both gas and electricity. HVAC gas heat is cheaper in cost and is best to warm indoor spaces quickly.
On the other hand, HVC electric heat needs heat pumps, space heaters and electric furnaces to fix for hot air rises and hot water heating. They demand lower maintenance and induce less carbon emissions.
1. Fan Coil System
Fan coils are condo heating or cooling systems that use a fan to drive air through hot or cold pipes. You can use both horizontal and vertical orientations in the condo units [1].
The building administration uses a boiler or chiller to control them from a centralized spot.
This implies that the main HVAC system of the building needs manual conversion from air conditioning to heating for hot air rising.
Fan Coil consists of a two-pipe system and four-pipe system. Two pipes are commonly used in the construction of fan coil units. During summers, the hot water flows through these pipes and vice versa in the winter season.
The four-pipe system, which is less prevalent, enables constant heating and cooling. That is because they can switch between hot or cold air every time. However, such fan coil units offer greater electricity consumption.
2. Heat Pumps
These are available in horizontal and vertical layouts. You can shift them from an air conditioning system to a heating system any time of the year [2].
Condo heat pump replacement costs typically range from $3,000 to $15,000 depending on the system type and complexity, with mini-split systems being most common for condos at $3,000-$6,000 for single zones and $6,000-$12,000 for multi-zone installations.
Central heat pump systems cost $5,000-$12,000 for standard to high-efficiency models, while premium systems can reach $18,000+. Additional expenses include electrical work ($500-$2,000), permits ($200-$500), old system removal ($300-$800), and potential condo board fees, bringing most total investments to $4,000-$10,000.
Factors affecting price include system size, efficiency ratings (SEER/HSPF), brand quality, installation complexity, and condo board aesthetic requirements, though the investment typically pays for itself through energy savings within 5-8 years, and many provinces offer utility rebates for high-efficiency models.
3. High-Velocity Air Handler Systems
It is the latest technology for cooling and heating in condo units. There are two parts to High-Velocity Air Handler Systems [3].
The exterior unit (condenser) stands on the balcony or rooftop whereas the interior unit on the inner walls of the flats.
4. Ductless Heat Pump System
You can install ductless heat pumps as a supplemental source of heating or cooling in high-rise or low-rise complexes that lack central HVAC units [4].
It consists of a small cable to connect the inside and external components. These save space in the room by mounting at distant places and are very efficient at heating and cooling.
Air Conditioning
1. Packaged Terminal Air Conditioning (PTAC):
The packaged HVAC units of PTAC, commonly known as Hotel Style Air Conditioning Systems, supply heating and cooling yearly.
While the supplemental electric system offers heat generation, the pumps take care of air conditioning.
In some condominiums, PTAC units use natural gas for heating.
2. Magic Pak System
This is similar to domestic gas or electric boilers. Moreover, it combines heating and air conditioning into one package. You can either have it with electricity or natural gas.
For increased comfort in apartment buildings, Magic Pak Systems provides heating and cooling for the whole year. Commonly found in high-rise condo buildings, Magic Pak Systems frequently uses HWC gas variants.

How Does a Heat Pump Work in a Condo?
Heat pumps in condos work by transferring heat rather than generating it, making them highly efficient for both heating and cooling. Here's how they function in a condominium setting:
Basic Operation:
Heat pumps extract heat from outside air (even in cold weather) and transfer it indoors during winter, then reverse the process in summer to cool your unit. The system uses refrigerant that circulates between indoor and outdoor units, absorbing heat from one location and releasing it in another.
Condo-Specific Configurations:
Mini-Split Systems are most common in condos, featuring an outdoor unit mounted on the building exterior (balcony or designated area) connected to one or more indoor units mounted on interior walls. These systems don't require ductwork, making them ideal for condo installations.
Central Heat Pump Systems work through existing HVAC ductwork if your condo has central air infrastructure. The outdoor unit connects to an indoor air handler that distributes conditioned air through ducts.
Installation Considerations:
Condo board approval is typically required for exterior installations, as outdoor units affect the building's appearance. Your condo corporation may have specific rules about unit placement, noise levels, and aesthetic requirements.
Electrical requirements include 240V power supply, which may require electrical upgrades depending on your unit's current setup. Most installations require professional assessment of your electrical panel capacity.
Efficiency Benefits:
Heat pumps can provide 3-4 times more heating energy than the electrical energy they consume, making them extremely cost-effective. They work efficiently in temperatures down to about 5°F (-15°C), though backup heating may be needed in extreme cold.
Key advantage: Unlike baseboard heaters or window AC units, heat pumps provide year-round climate control in a single, energy-efficient system that can significantly reduce your utility costs.
