Merit Series High Efficiency

For nearly 150 years, Lennox has stood for innovation, dependability and reliability in heating and cooling equipment. The entire Merit® Series carries on that tradition with pride, because it’s built with smart designs, and thoroughly tested to ensure it will exceed your expectations. The single stage operation (one heat production output level and one fan speed) has been the go to design and operation of gas furnaces since their inception.

Elite Series High Efficiency

True to their name, Elite® Series products are a cut above when it comes to making people comfortable in their homes. With impressive features and capabilities, Elite products not only deliver exceptional comfort, but also outstanding energy efficiency. Compared to conventional heating and cooling products, Elite Series can save you hundreds of dollars in energy costs each year. The Elite series high efficiency model incorporates a second set of heat exchangers for greater energy efficiency when compared with the Elite series 80% efficiency unit.

Dave Lennox Signature® Collection

Lennox’s Signature series model in standard efficiency is home comfort excellence. This furnace incorporates two stage operation (high/low output) with a variable speed blower motor. Variable speed fans are more electrically efficient when compared to standard fan motors and lend to better home comfort. In addition, this furnace offers more feature-rich software, so that when you combine it with Lennox’s iComfort thermostat, you will have features you would otherwise not have (e.g., a diagnostic alert system to indicate when there’s a problem with the furnace and what it is, WiFi, etc.). If you want the best within the standard efficiency group, this is the choice.

We install Lennox furnaces but also Amana, Carrier, Trane, Goodman, Napoleon, WeatherMaker, Rheem and many more brand.
