What air conditioner should you get when it’s time to replace your existing AC?

That’s the million-dollar question. Or rather, it won’t cost you a million dollars, but it’s still a large investment. So getting the right answer matters!

We install a lot of Trane XL18i air conditioners, because it’s the “right” answer for many of our customers.

Why would you want a two-stage air conditioner? We’ll talk more about that in later sections, but in brief, the ability to operate at 70% capacity allows your system to run for longer as it’s cooling the home. This is a good thing, believe it or not! Because it gives the air more time to distribute evenly throughout the home.

So, for example, it will better cool your upstairs rooms, whereas a single-stage unit might result in a lot of hot or cold spots in your home. So if you have trouble sleeping at night because it gets too hot, a two-stage AC can help!

The other benefit of two-stage equipment is that it will dehumidify for longer. One of the most important functions of the air conditioner is to remove moisture, which contributes to cooling your home. If you have trouble with allergies, mold, or general humidity, this can work wonders.

XL18i SERR Rating, Cost Savings and Comfort

SEER stands for Seasonal Energy Efficiency Rating. If you know what it is, you probably know that higher numbers are better. At up to 18 SEER, the XL18i is one of the more efficient air conditioners on the market. While there are cutting-edge home ACs over 20 SEER, most residential ACs top out at a 20 SEER rating.

This makes the XL18i somewhere between mid-range and high-end air conditioners, making it a great option to meet various needs without being the most expensive option.

If your current air conditioner is older, any modern system will be a large upgrade in terms of cost savings and comfort. But how much can you expect to save?

The graphic below will give you a rough gauge of cost savings. Remember that this is savings on your cooling costs alone, not your entire energy bill. But if you’re overspending on cooling now, it can mean savings of hundreds or even thousands of dollars per year!

Additional Features of the XL18i

I want to point out two features that are attractive to many homeowners.

One, the XL18i is whisper quiet compared to many other options. If your AC is just outside a bedroom window, for example, the noise level can matter.

And two, the XL18i comes with Trane’s Weatherguard Top. This top does two things: it keeps your outdoor unit free from debris that might fall into the fan (like leaves or sticks), and it allows enough breathing room for the fan to function as intended. It can be a much better option than having either an open top or trying to DIY a protection solution.

Who Should Consider an XL18i AC?

Now we get to you. Do you need this, or is it too much (or not enough)? When we talk to people in their homes, we walk them through the process of finding the solution. But the considerations below can help you figure out the answer before speaking to an HVAC professional.

#1: Is your house humid?

Muggy summer rooms? Allergies? Humidity fogging up your windows? These are all signs of a poor HVAC system and the need for an advanced system to manage humidity well. Two-stage air conditioners will do much better than single-stage units at accomplishing this.

#2: Are there rooms that are much hotter than others?

I mentioned earlier that it might be time for an upgrade if you have trouble sleeping at night because your bedroom is too warm. This is the sort of thing we look for when recommending air conditioner systems.

#3: Will you be in your home for 5+ years?

The XL18i isn’t a low-end option, so the initial investment is higher than some. If you want to recoup your investment with cost savings on energy bills, you’ll need to use it for several years. If you plan on staying in your home for many years, this can be a great time to make that investment that will save you in the long run.

#4: What’s the most significant factor for you, cost or comfort?

If your answer is “all comfort, I want the best” or “I need the most affordable option,” there may be better options. But if your answer is a bit of both, the XL18i may be right for you.

Who Shouldn’t Consider an XL18i AC?

If each of the considerations above indicates who should want the XL18i, the reverse is true in most cases:

  1. If your home doesn’t have a basement, it may not have issues with humidity.
  2. A two-stage compressor may not be needed if your home cools evenly.
  3. If you may be selling the home within the next five years, you’re likely better off with a more modest upgrade to your current system.
  4. You have a small area for the outdoor unit. The XL18i is very large and stands over 5 feet tall. Allowing it enough space to function can be a challenge in some yards.

These aren’t the only considerations for homeowners; only you know your pain points that HVAC can solve. Talking them through with a licensed representative can be a significant first step in picking your dream system.

By now, you should know a few things: what makes the XL18i different, whether or not it might be the right air conditioner for you, and what the next steps are to finding your perfect system.

The last step is to contact us to schedule your free, no-pressure estimate. You’ll get exact pricing and various recommendations to match your budget and comfort needs.
