Air Conditioner or Heat Pump? Choosing for Calgary
Calgary summers keep getting hotter, and more homeowners are asking whether a heat pump makes sense here. Here’s how to choose between a central air conditioner and a heat pump, and what efficiency ratings actually mean.

A/C vs. Heat Pump: What's the Difference?

- Central air conditioner: Cools only. Pairs with your existing furnace and shares its ductwork.
- Heat pump: Works like an A/C in summer and runs in reverse in winter to pull heat from outdoor air into your home.
Modern cold-climate heat pumps keep heating well below freezing, but output drops in Calgary’s deepest cold snaps. That’s why most Calgary installs are hybrid systems: the heat pump handles cooling and milder heating days, and the gas furnace (or electric backup) takes over on the coldest nights.
Understanding Efficiency Ratings
- SEER / SEER2: Cooling efficiency over a season. Higher is better.
- EER / EER2: Cooling efficiency at peak heat.
- HSPF / HSPF2: Heating efficiency for heat pumps.
Why Variable-Speed Equipment Is Worth It
Variable-capacity (inverter) systems speed up and slow down to match demand instead of slamming on and off.
- Higher efficiency ratings and lower bills.
- Quieter operation, often noticeably quieter than entry-level units.
- More even temperatures and better humidity control.
- For heat pumps, better heating performance in the cold.
Popular Models to Compare
Every major manufacturer now offers high-efficiency variable-capacity equipment. A few well-known options:
- Carrier Infinity: Premium variable-speed heat pumps and A/Cs with very quiet operation.
- Lennox XC / XP series: High-efficiency A/Cs and heat pumps.
- Trane XV series: Variable-speed units known for quiet running.
- Rheem / Ruud: Solid mid-to-high efficiency options.
- Mitsubishi and Daikin: Popular cold-climate heat pumps, including ductless.

Air Conditioning & Heat Pump FAQ
What is emergency heat on my thermostat?
On a heat pump system, emergency heat (EM heat) turns the heat pump off and runs only the backup heat, such as electric heat strips or a furnace. Use it only if the heat pump stops working, because it usually costs more to run, and call for service.
How much does a central air conditioner cost in Calgary?
It depends on your home's size, the unit's efficiency, your existing ductwork and whether your electrical panel has room for it. We'll look at your home and give you an upfront quote before any work starts.
Do I need an electrical upgrade for a new air conditioner or heat pump?
A central air conditioner or heat pump needs its own 240-volt circuit and an outdoor disconnect. We check your panel capacity first, and many Calgary homes have room without a full service upgrade.
