Light Commercial Unit Heaters

A blend of advanced engineering and high-quality materials, unit heaters are perfect for commercial applications and the garage or workshop in your Portland home. Available in 2 designs and several capacities, Lennox puts them through rigorous quality testing for long-lasting performance.

Tubular heat exchanger is the key

It’s curved design provides superior heat transfer by exposing the entire heating surface to the open air. Its rounded surfaces minimize air resistance to allow even heating across all surfaces, which decreases stress on the heat exchanger.

What is Btu?

British Thermal Unit (Btu) is a measurement of heat energy. One Btu is the amount of heat needed to raise 1 pound of water by one-degree Fahrenheit.

What is Btuh?

British Thermal Units per Hour (Btuh) is the yardstick used to estimate the capacity of a heating system. For reference, 12,000 Btuhs equal one ton of heating or cooling per hour.

Had the pleasure to meet a few of the Midway Heating Company crew. After experiencing service from several other companies out there in the past I have to say this team is more knowledgeable, easy to deal with.

More than satisfied with their service Thank you Nate, Alex, and the whole crew....
