There’s plenty of confusion when it comes to purchasing a new heating and air system for your house. One of the most common and easiest to explain is the difference between a single stage unit, a two stage unit and a variable capacity unit. The image below shows the difference between the three.
Typically the more efficient systems will be two stage or variable capacity. Less efficient systems will be single stage.
The Lennox single stage ML14XC1 is a popular choice for air conditioning. For two stage we suggest the Lennox XC16 air conditioning unit. Variable capacity air conditioning can be accomplished by using the Lennox XC20 model.
