Bigger Doesn’t Mean Better When It Comes to HVAC

New seasons typically inspire you to get prepared for the upcoming weather. This is especially true for spring. We’re prepared for our cold weather to thaw out and make way for warmer, spring temperatures. When this season comes around, you’ll more than likely shift your focus from heating to air conditioning service. Have you realized that you need a new air conditioner? If you do, then you’ve found the right blog. Today, we’re going to discuss the importance of proper HVAC sizing.

Precise calculations are non-negotiable. You need great HVAC service to ensure that you’re comfortable during the spring and summer season. We’re a family team that’s also precise. We’re available to help you get proper AC installation in Dickson, TN.

Why Bigger Isn’t Better

We meet lots of homeowners who have oversized air conditioners in their homes. When we do a little research into why the system was oversized in the first place, the answer is typically due to human error. Either the homeowner themselves or an amateur technician matched them with an air conditioner that’s too large. The reasoning is typically that they’d rather have an excess of power rather than not have enough power. While we understand this line of logic, we want to break down why this is a problem below.

An oversized air conditioner results in short cycling. What’s short cycling, you ask? Short cycling is when your air conditioner starts, runs for a short amount of time, stops short, and then turns on again to start the process all over again shortly after.

Short cycling might be something that you want to convince yourself to live with. Sometimes, you might not even see the negative impact of it on your end. Just know that it’s not something that you should overlook. Short cycling is terrible for your efficiency and your comfort.

We like to compare it to the way your car runs driving around surface streets in the city versus the highway. You’re most efficient when you’re driving on the highway without stops. You’re not reaching the highest capacity with your miles per gallon when you’re riding around on the streets. This same logic applies to short cycling, and that’s why it’s so terrible for your AC. In addition to terrible efficiency, it can also lead to these problems:

  • Uneven Temperatures: An oversized air conditioner will flood your home with cool air too fast. This results in uneven temperatures.
  • High Energy Bills: Short cycling is an inefficient practice. Over time, you’ll notice that you’ll start paying more for lower AC quality.
  • Poor IAQ: A large system doesn’t have the right timing or capacity to dehumidify your home properly. This results in humidity problems in your home.  
  • Repair Issues and Breakdowns: Short cycling is hard on your AC. This can easily result in repair needs and even breakdowns.

If you want to avoid these problems, then it’s a great idea to correctly size your AC with the help of our team.

What Happens If It’s Undersized?

We talked about what can happen if your home’s air conditioner is oversized, but what happens if your home’s air conditioner is undersized? The most obvious problem is that it won’t be able to cool your home adequately. You’ll also notice long AC cycles and high energy bills.

You won’t have to worry about an oversized or undersized AC with our professionals. We conduct the right calculations for your needs.
