When it comes to installing a new HVAC system, there are a lot of choices to make. One of the most important decisions is whether you should get a single-stage, two-stage, or variable-speed air conditioner. In this blog post, we will discuss the pros and cons of each type of system so that you can make an informed decision about what is best for your home.
A Basic Explanation of Single-Stage, Two-Stage, and Variable Speed Air Conditioners
Single-stage AC systems are the most common type of system. They have one speed, and they run at that speed until the temperature in your home reaches the set point on your thermostat. Then, the system shuts off (unless you direct the fan to keep running). Single-stage systems are less expensive than variable speed or two-stage systems; they are also less efficient and can have trouble evenly cooling large homes.
Two-stage AC systems have two speeds: low and high. This type of system will run at its maximum capacity if necessary. However, most of the time, the system can run at about 6o to 70 percent of its max capacity while keeping your home comfortable and using less energy. Two-stage systems are more expensive than single-stage systems but more efficient.
Variable speed AC systems can run at various speeds, many models using as little as 25 percent of the max capacity. Because variable speed air conditioners can maintain a comfortable temperature with very little energy, they are the most efficient type of air conditioner. They are also the most costly type of air conditioner to install.
Would I Benefit From Installing a Variable Speed Air Conditioner?
Now you're probably wondering: is the extra cost worth it for a variable speed AC? The answer depends. You’re likely to benefit from installing a variable speed AC if the following situations apply to you:
- You own a large, sprawling, or multi-story home. Variable speed systems are better at providing even temperatures throughout a home, helping avoid pesky "hot and cold spots."
- You live in an area with long, hot summers and want to keep your energy costs low. A variable speed system’s extra efficiency can significantly reduce your energy costs, especially if you run your air conditioner a lot.
- You plan on staying in your current home for a long time. If you have no plans to move in the near future, then you'll have the opportunity to reap the rewards of an energy-saving variable speed system. If you plan on moving within the next two or three years, you may want to opt for a single- or two-stage system if you must replace your AC. Remember, though, that a newer, ultra-efficient AC can be a very attractive selling point to potential homebuyers!
It's also worth noting that other updates can improve your home's energy efficiency and temperature control, such as air-sealing, updated window treatments, new insulation, and improved ductwork. For this reason, opt for an HVAC contractor who will come to your home and provide you with a comprehensive consultation about your cooling needs.
