As with anything you buy, the more features you include in a new air conditioner, the more the up-front cost will be. But the great thing about heating and cooling systems is that higher installation costs almost always translate to long-term energy savings. One feature that most certainly falls into this category is the compressor in a two-stage air conditioner. Today we’re going to talk about what a two-stage air conditioner is and whether or not it’s worth it to upgrade to this type of system in your home!

What is a two stage air conditioner?

A two-stage air conditioner is a cooling system with a compressor that operates at two different capacities. Unlike a traditional air conditioner, which has a compressor that is always running at full blast, a two-stage air conditioner’s compressor has both a “medium” and a “high” capacity. The “medium” capacity is used when there is a moderate demand for cooling in your home, and the “high” capacity is only used when it’s extremely hot outside and the “medium” capacity isn’t strong enough.

How can you save money with a two-stage air conditioner?

When you look at how much energy each part of your air conditioner consumes, your compressor is near the top of the list. So anything you can do to ease the load on your compressor will significantly lower your cooling bills.

On average, a two-stage air conditioner’s compressor uses its “medium” capacity about 80 percent of the time. The remaining 20 percent is left for days with extremely high cooling demands. That means that a two-stage air conditioner uses a significantly less amount of energy than a traditional air conditioner a huge majority of the time that it is operating. That’s a whole lot of savings!

In addition, a two-stage air conditioner goes through less frequent cooling cycles than a traditional air conditioner. That’s because the high capacity that’s used at all times by a traditional air conditioner will cool your home faster and more forcefully, which shortens its cooling cycles. When you consider the fact that an air conditioner consumes the most amount of energy when it’s starting up and shutting down, you can see how a two-stage system will consume less energy by cooling your home more gradually with longer and less frequent cooling cycles.

Are there any other benefits to installing a two-stage air conditioner?

Saving energy is certainly one of the best reasons to install a two-stage air conditioner, but another great benefit is that it will make your home more comfortable. As we mentioned above, a two-stage air conditioner will cool your home more gradually because of its “medium” capacity. This means that your home will have less severe temperature swings (only within a few degrees) and will always feel consistently comfortable.

Is it worth it to upgrade to a two-stage air conditioner?

If you don’t mind the slightly higher up-front costs of a two-stage air conditioner, it’s worth it to install one. You’ll not only see significant energy savings throughout your system’s lifetime, but you’ll also have a more comfortable home.
