Heat Pump vs PTAC (Packaged Terminal Air Conditioner): Which Is Better for Toronto Homes and Apartments?

If you live in a Toronto condo, apartment, or a home without central HVAC, you might be considering a heat pump or a PTAC (Packaged Terminal Air Conditioner) for heating and cooling. But which option is right for you in terms of comfort, energy savings, and year-round performance? Here’s an expert comparison from Temperature Care.

How Do They Work?

PTAC (Packaged Terminal Air Conditioner):

Self-contained heating and cooling unit, usually installed under a window (like in hotels)
Requires an opening in an exterior wall for venting and air exchange
Heats and cools one room at a time, using either electric resistance (for heating) or a heat pump mode (if available)

Heat Pump (Mini-Split or Ducted):

Uses an outdoor compressor and an indoor air handler (or wall-mounted unit)
Provides both efficient heating and cooling, often for multiple rooms or zones
Runs quietly and is much more energy-efficient than most PTACs

Efficiency and Cost Comparison

Feature	Heat Pump (Mini-Split)	PTAC
Heating & Cooling	Yes (both, very efficient)	Yes (but less efficient)
Area Served	Whole home or multiple zones	Single room
Noise Level	Very quiet	Louder, especially older units
Operating Cost	Much lower	Higher (especially in winter)
Air Quality	Advanced filtration	Limited filtration
Aesthetics	Sleek, wall-mounted	Large, boxy under window
Rebates	Generous, available	Rare for PTAC

Heat pumps can save up to 50% on energy bills compared to PTACs or window units, especially in Toronto’s climate.
PTACs are simple to install, but tend to be noisy and inefficient—especially for heating.

Comfort and Air Quality

Heat pumps:
- Maintain steady, even comfort—no cold/hot spots
- Filter air and control humidity (great for allergies)
PTACs:
- Can cause drafts, noise, and inconsistent temperatures
- Often struggle to keep rooms comfortable in very hot or cold weather

Installation & Rebates

Heat pumps:
- Professional installation required, but most units don’t need big wall holes
- Eligible for major rebates:
  - Canada Greener Homes Grant
  - Enbridge Home Efficiency Rebate Plus
PTACs:
- Easy to retrofit in older buildings, but may not qualify for rebates

Which Should You Choose?

Choose a heat pump for quiet, energy-efficient, year-round comfort in condos, apartments, and homes.
Choose a PTAC only for a quick, cheap solution in one room, or if your building doesn’t allow other systems.
