If you’re having a new HVAC system installed in your home or office, finding the right size unit for your unique needs is a vital step in the process.

You see, if your system ends up too big, you’ll waste more money than necessary on energy bills. Along with this, it will heat/cool the home so quickly that it will be turning off and on more than it should. This causes a lot of wear and tear, and it could cause your system to eventually break down prematurely.

On the flip side, if it’s too small, it won’t do an efficient job of keeping your house as cool or warm as you want it. Not to mention, it will end up being way overworked trying to keep up with the space it’s working with 


– and when it comes to those hot, humid summers in Nashville, the last thing anyone wants is an A/C unit that can’t produce results!

But being too big or too small isn’t the only issue people tend to face. It could also be that the air conditioner isn’t the right size for the ducts, the ductwork isn’t insulated correctly, the runs are too long, or the wrong sealing materials are used. All of these cause issues that can lead to inefficiency and appliance breakdown.

In the end, getting sizing, measurements, and all of those other odds and ends right the first time is essential for the health of your system and home! Fortunately for Nashville residents, the Airbusters team can help with it all. Here are some important questions we address throughout the process.

What’s Your Square Footage & BTU?

When installing new heating or cooling equipment in your home, one thing we need to know is your BTU. What does BTU stand for? This stands for British Thermal Unit, and it’s what we use here in the U.S. for calculating how much energy your home uses to stay at a comfortable temperature range.

Homes typically use around 25 BTUs for every square foot in the space, so yours can be figured out by simply multiplying your square footage by 25.

Once that’s determined, you’ll have a good starting point for what you need. That said, there are still many other things to consider!

Other Factors in Determining HVAC Size

Now, once the BTU is figured out, you’re not done yet. There are many other things our professional crew will take into consideration. Some of these things include:

  • How many windows and doors do you have?
  • How much sunlight can get into your home?
  • Where does the sun hit your home?
  • How insulated is the space?
  • What type of roof do you have?
  • How many people are living in the home?
  • How is the space going to be used?

These, along with many other factors, will determine just how to approach your new HVAC system to ensure you get the efficiency and longevity you’re hoping for.
