Olsen HVAC Equipment
Furnace Series

ECR International markets a line of residential and commercial gas and oil furnaces, boilers and air conditioners under the Olsen/Airco brand. At one point in time, Olsen marketed warm air products under its name, while furnaces were sold under its Airco brand. Today, there is apparently no difference between the equipment marketed as Olsen and the equipment marketed as Airco, and the distinction remains for historical reasons.

ECR International is headquartered in Utica, N.Y,, while its Olsen division is headquartered in Wallaceburg, Ontario.


Corporate History

Olsen and Airco were furnace brands produced by Duomatic-Olsen, later known as DMO Industries. DMO Industries changed its name to Olsen Technology Inc. in 1989. In December 2000, it became part of ECR International when that company acquired certain assets of what was then Olsen Technology from Canadian Manoir Industries Ltd. to form ECR International Ltd. - Olsen Division.

Product Lines

Olsen/Airco markets a line of mid- to high-efficiency boilers, furnaces and air condtioners. Its GTH gas furnaces are both are 4-position units, ranging from 40,000 to 120,000 BTU and up to 95 percent AFUE. More options are offered among oil furnaces, which include lowboy and highboy selections. Units featuring the variable speed motor are capable of reaching up to 85 percent AFUE, according to the manufacturer. A 2-stage, multi-position electric furnace also is available.

Olsen/Airco also offers 13 and 14 SEER air conditioners with energy-efficient scroll compressors, high/low pressure switches and durable casing.

Finally, the company manufactures three styles of boilers: gas, condensing gas and oil. The company says it designs its boilers with energy efficiency, dependability and ease of maintenance in mind. Several of its condensing gas and oil boilers are rated Energy Star's "Most Efficient."
