Types of Air Conditioners
Single-Stage vs. Two-Stage
A single-stage air conditioner is the most basic and standard type of air conditioner. The term Single Stage refers to the operating level of the unit. A single-stage unit only has one operating level, meaning when the unit is running, it is always running at 100% capacity, regardless of the amount of cooling that the space needs at that time. These units usually cycle (turn on and off) more as the temperature inside the house fluctuates above and below the thermostat’s set point. Single-stage units can be the most affordable options upfront but are typically less efficient, resulting in higher utility expenses.
Two-stage air conditioners can be much more efficient than single-stage units. The term Two Stage refers to the operating levels of the unit. Unlike a single-stage unit, a two-stage unit can run the air conditioner’s compressor at two different levels. On mild days, the unit will operate at about half capacity, which will be more efficient. This allows the air conditioner only to use the exact power needed to cool the home or maintain the thermostat’s set point. These units are much more efficient and provide next-level comfort inside the home. Another benefit to a two-stage unit is greater humidity removal. The unit can have a longer cycle time by operating on a lower stage, which removes more moisture from the air. A two-stage unit generally has a slightly higher upfront cost than a single-stage unit, but typically, utility costs are lower, and comfort is greater over the unit’s lifetime.
The Most Efficient Pair for Ultimate Comfort and Utility Savings!
To get the absolute most in efficiency and indoor air comfort, combine a two-stage air conditioning unit with a modulating furnace! Each of these units provides the most control for home air temperature year-round! Combining these two units also provides the ultimate utility expense savings over the lifetime of each!
