Variable-Speed Compressors and the Lennox XC20 Air Conditioner

When it comes to running household appliances, we prefer those that can perform their jobs well without consuming too much energy — and air conditioners are no exception. If you’re in search of a new air conditioner, you might want to consider installing a unit that is equipped with a variable-speed compressor.

Four Seasons Air Specialists is your trusted HVAC company in Lino Lakes MN that offers a wide array of energy-efficient air conditioning systems, including the Lennox XC20.

What are the Different Kinds of Compressors?

An air conditioner’s compressor creates the cooling capacity for the unit and can come in different kinds, including single-stage, two-stage, or variable-speed options.

Single-stage compressors have a basic function: full on. With this kind of compressor, your air conditioner turns on at 100 percent capacity and then OFF until your thermostat reaches your desired temperature.

A two-stage compressor has a low capacity option to handle smaller demands and a larger option to meet heavier demands. In cases where you don’t need the compressor to operate at 100 percent capacity, having a two-stage compressor gives you the choice to operate the system at a lower speed, thus saving energy.

Variable-speed compressors, also known as inverter compressors can operate at different levels of output depending on the situations. Air conditioners equipped with variable-speed compressors can run at full capacity during the hottest days of summer or at a reduced capacity for milder days. A variable-speed compressor is the most energy-efficient option compared to single-stage or two-stage units.

Benefits of Variable-Speed Compressors

In addition to lower energy consumption, inverter compressors offer a number of other benefits, including:

• Better air filtration
• Greater indoor comfort
• Longer dehumidification
