This brand is made in Canada through a partnership with NUTECH BRANDS.

The air handlers feature full airflow modulation and use a standard A coil for air conditioning. They are backed by a good guarantee but their cooling capacity is limited to 3.5 tons which may not be adequate for many homes.

They are available as a standard air handler or as a "clean air furnace" which has a built in heat recovery ventilator for providing fresh outdoor air for better indoor air quality.

The CBWMV model air handlers are available in five sizes to match the requirements of any home. They are multi-position, have built-in freeze protection, a variable speed fan motor, and use state of the art electronic control.

They are backed by a very good warranty but are only available through their factory authorized dealer network.
