There aren’t many cooling and heating technologies that can both cool and heat a space at the same time. While that normally is not something a business or a homeowner would want to do, in a very large space there are times when it would be beneficial to be able to cool some rooms while heating the rest.
Advanced Lennox systems come with variable speed blowers and adjustable burner controls to provide different levels of heating and cooling as needed. This lets residential equipment from Lennox operate in very strict heat ranges. While equipment from other companies might vary by as much as 3 degrees above or below the thermostat setting, Lennox equipment generally stays within a single degree of the set temperature thanks to the highly flexible technology.
Lennox offers a highly comprehensive warranty on any of the top-end Dave Lennox Signature Collection furnaces. These furnace heating units get component and compressor coverage for 10 years and heat exchanger coverage for 20 years. When using the Elite series coverage drops to 5 years for components, 10 years for the compressor and remains at 20 years for a heat exchanger. Finally, the Merit series furnace get 5 years of coverage for both components and compressors and 20 years is provided for the heat exchanger.
