What is a Variable-Speed Air Conditioner?

Your HVAC system is integral to your home's comfort, but traditional single-stage units are typically less efficient than advanced variable-speed air conditioners. 

If you’re in the market for an AC upgrade, consider these top-of-the-line setups before making a purchase. 

Join us as we answer all your questions about variable-speed HVAC systems so you can decide which type of unit best fits your needs. 

What are variable-speed air conditioners?

Variable-speed air conditioners are the latest designs in cooling technology. Here’s how they stand out from the competition. 

What makes variable-speed air conditioners different?

Traditional single-stage systems frequently cycle off and on at a fixed speed. They stay off until your home begins to heat up, and then they run at full blast to lower the temperature. This inefficient cycle can significantly increase your energy bill, especially during the summer. 

Two-stage systems offer a middle ground between single-stage and variable-speed systems. They offer low and high speeds to better adjust to varying temperatures. However, they’re not as adaptable as premium variable models. 

On the contrary, modern variable-speed AC units continuously adjust to temperature changes in order to keep your home comfortable. These dynamic compressors stay on for longer periods of time at speeds high enough to maintain your chosen temperature instead of running full blast intermittently. 

What is the average cost of variable-speed air conditioners?

The upfront cost of a variable-speed air conditioner will be more than a single-stage model. You can also expect higher installation and repair costs since these systems are more complex than old-school AC systems. 

However, they typically pay off over time in the form of lower utility bills. They’ll also keep working much longer than single-stage AC units because the compressors don’t burn out as quickly. 

Variable-speed air conditioner benefits

You’ll find plenty of reasons to love variable-speed HVAC systems. Here are a few of the top benefits they offer.

Improved air quality

The longer run cycles of variable-speed air conditioners allow them to filter more air. This means your air filter can capture more particulates that might otherwise end up in the air you breathe, reducing the amount of allergens in your environment.

Cooling efficiency

Increased energy efficiency is one of the main reasons people choose variable-speed AC units. A higher run time on a low setting allows the system to maintain a comfortable climate without straining your electrical system. 

Best of all, the air handler on these units evenly distributes cool air throughout your home. If certain rooms in your house tend to stay warmer than others, one of these systems could help solve the problem. 

Most cost-effective

Since variable-speed air conditioners are more energy efficient than single-stage units, you can look forward to lower utility bills. Of course, this can vary depending on the difference between the outdoor temperature and how cool you like to keep your home. However, after the initial costs, you can expect to pay less to keep your indoor climate comfortable. 

Variable-speed air conditioners are quieter

Older single-stage HVAC systems are often noisy. If you’re standing next to your outdoor unit when it kicks on, it might be hard to hear anything above the whirring blades. 

On the contrary, variable-speed AC units switch on and off less frequently and often operate at lower speeds. You might not even hear your system running! 

Controls humidity levels

With single-stage systems, your home is constantly going from warm to cool and back to warm, resulting in fluctuating humidity. But homes with variable-speed AC units enjoy near-constant air movement and stable temperatures, so it’s easier to maintain optimal humidity levels. 

When should you consider variable-speed air conditioners?

Variable-speed air conditioners aren’t the right solution for everyone, but they’re an excellent option for many homeowners. Here are a couple of situations when they’re worth considering. 

If you plan on living at your current residence long-term

Variable-speed AC systems are a big investment, so you probably won’t want to purchase one for a home you’re just flipping or don’t plan to stay in very long. However, if you intend to live in your home for years to come, they can play a major role in your overall comfort level. 

If you live in an area with varying temperatures 

In mild climates with steady temperatures, a variable-speed air conditioner might not be worth the extra upfront costs. 

However, these systems can make a big impact on your energy use and utility bills if you’re in a climate that experiences frequent fluctuations or extreme highs and lows. Because they constantly adjust to meet your needs–and often run at low speeds to maintain optimal temperatures–they can keep you comfortable without running wide open around the clock.
