Benefits Of A Two-Stage Or Variable-Speed AC
A single-stage AC is the most common type of system seen in central AC. When it is time to replace your system, you might want to consider the benefits of going with a two-stage or variable-speed AC. Both types of systems offer far more benefits than single-stage systems.
Prevent Temperature Swings
When you have a system that can function at more than a single speed, it allows your home to be at a constant, comfortable temperature. With a single-stage AC, your AC is either on or off. This often means you experience significant temperature fluctuations in your home, which makes it difficult to achieve a consistent level of comfort. When your AC has multiple speeds, it is easier to keep a constant temperature because the system is consistently running, but at a lower level of power.
Efficiency
A single-stage AC is among the most inefficient forms of AC because when it is on, it's constantly running at full power, regardless of temperature. A two-stage system is far more efficient because it can be used at full power when it is extremely hot, but the power is automatically reduced when the temperature is not hot enough to warrant high power usage. A variable-speed system is even more efficient since it can run at almost an infinite number of speeds to avoid unnecessary use of power. Although the upfront costs associated with replacing your single-stage system with a two-stage or variable-speed system can be costly, the long-term savings in your utility bill might be worth the splurge.
Improved Air Quality
Both two-stage and variable-speed systems improve air quality more than a single-stage system. Since the unit is always on, it is constantly filtering particles out of the air. Additionally, people who live in humid environments will find these systems do a better job of reducing humidity in the air, making the environment more comfortable. High indoor humidity causes several issues. Elevated humidity often means you need to run the air conditioner longer to bring the environment to a cooler temperature before it actually feels cool. People with allergies or breathing problems find their respiratory problems are often aggravated by high levels of humidity. Additionally, a humid indoor environment causes dust and dirt to stick to surfaces making them harder to clean. High humidity also increases the risk of indoor mold.
Both two-stage and variable-speed systems have benefits that make them far more efficient than a single-stage AC. When you're in the market for your next AC, consider upgrading your system to one that will make your home environment more comfortable with less energy usage.
