Best Air Conditioner Brands

After years of servicing and installing AC units, as well as purchasing them for our own homes, we know a thing or two about air conditioners. The very best AC brands offer a variety of options, all of which are efficient and durable. Our top picks are tried, tested and well-liked by consumers.

AirEaseTM by Lennox

AirEaseTM is a trusted and reliable AC brand. With more than 10 years of research and development invested in their products, AirEaseTM provides some of the best air conditioning units on the market.

AirEaseTM air conditioners integrate Omniguard™ features, including:

  • Total Corrosion Protection Technology – this feature offers protection against coil corrosion, for a durable and long-lasting AC unit.
  • Antimicrobial drain pan – this provides cleaner air coming into your home.
  • Optimized installation features – this includes pre-formed duct flanges, extended condensate drain and rubber plugs for faster connections and installation.
  • Tight gauge steel cabinet – this means less air can leak from the unit (i.e. less than 2%).

These features make for more efficient and effective air conditioning units. As well, they allow Alberta AC installers to get your system up and running faster.

The optimized design of an AirEaseTM AC also makes it more reliable and easier to service. For example, easy access to coils and a removable service panel allow for faster maintenance. Additional features, such as tube sleeves to prevent copper to copper tube rub and the use of high-quality fan blades, mean your unit will be reliable for years to come. 

This promise of dependability is backed by a 10-year parts warranty, a lifetime warranty on the heat exchanger and a 98% reliability rate.

Some of AirEaseTM’s best air conditioner units include:
