Lennox Heat Pumps

Lennox offers a variety of efficient, reliable, and quiet heat pumps. All of Lennox’s heat pumps are ENERGY STAR® qualified, offering superior SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings.  With unique features, such as solar support, dual-fuel capability, humidity control, and proprietary SilentComfort technology, Lennox heat pumps offer optimal cooling and heating throughout the year without inflating your energy bills. 

 

Types of Lennox heat pumps

Lennox offers two types of heat pumps: single-stage and multi-stage. Both types fall under three different series – Signature, Elite, and Merit. All Lennox units come in different sizes, ranging from 1.5 to 5 tons. The term “ton” is used to describe the cooling/heating capacity of the unit. One ton equals 12,000 BTU (British Thermal Unit).

A single-stage heat pump provides a single level of heating and cooling output, whereas a two-stage unit has two levels of operation: high and low. During hot summer days, a high-level mode runs the compressor at 100% capacity; during milder days, the compressor runs at 80%. This system ensures even cooling, efficient operation, and optimal humidity control.
