How Do I Find The Tonnage Of My AC Unit

OK, real talk: As a homeowner, replacing your air conditioning unit is absolutely no fun. It can be expensive, the research is a time-suck, and unless you’re Austin HVAC pros like we are, you’ll quickly come up against unfamiliar industry jargon (like “AC tonnage”) that’ll leave you frustrated, confused, and worried about making a costly mistake.

If that sounds familiar, we’re here to help!

What Is AC Tonnage, Anyway?

As you might imagine, an AC unit cooling a 3600 square-foot home requires more oomph than one cooling a 1200 square-foot home. The technical HVAC term for “ooomph” is tonnage—the measurement of an AC unit’s cooling capacity. So, if someone asks you what “size” AC unit you’re looking for, they’re not asking for physical dimensions; they’re asking for a number of tons.

Now, stick with us because we have to get a bit engineer-y and math-y for a second. (You’re about to get some ammo for your next trivia night though, if that’s any consolation.)

In the U.S., heating and cooling capacities are measured in British thermal units (BTUs). One BTU is the amount of heat required to raise the temperature of a pound of water by 1oF. And 288,000 BTUs will melt 2,000 pounds of ice in 24 hours. Of course, 2,000 pounds is… a ton. Oooooooh. It’s all coming together now, isn’t it?

Obviously, AC units have little to do with heating water or melting ice. Instead, they remove heat. So, in HVAC-land, tonnage describes the amount of heat an AC unit can remove from a home in one hour. One ton is equivalent to 12,000 BTUs (288,000 BTUs/24 hours).

Whew. Let’s keep going.

Why Does AC Tonnage Matter?

Since tonnage describes the cooling capacity of your AC unit, it’s important to right-size your system. A unit that’s too small won’t be able to keep up with mid-summer temperatures. An HVAC system that’s too big may turn on and off more frequently than necessary, resulting in unnecessary wear and tear, air that’s uncomfortably damp, and higher electrical bills.

How Can I Figure Out The Tonnage Of My AC Unit?

Finding the tonnage of your AC unit may be as simple as walking outside and reading the label on the condenser unit. Most of the time, manufacturers don’t list tons, though; they list BTUs instead.

Lucky for you, we already taught you that math! Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3-ton unit.

Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60. Or, you might see a three-digit number starting with 0. If you find one of those numbers, chances are good it’s the unit’s BTUs:

  • 018 = 18,000 BTUs = 1.5 tons
  • 024 = 24,000 BTUs = 2 tons
  • 030 = 30,000 BTUs = 2.5 tons

And so on.

 

What Size Unit Do You Need?

In general, one ton will sufficiently cool 400 square feet of space. So, if you have a 2000 square-foot home, you likely need a five-ton AC unit. But square footage isn’t the only factor that determines AC tonnage requirements.

Also, it’s not necessarily the case that you should replace your existing AC unit with a unit of the exact same size. For example, if you’ve done any remodeling to increase your livable square footage, you may need a larger unit. If you’ve improved the energy efficiency of your home, you may be better off with a smaller one.

HVAC contractor Austin, TX, can help you with fall HVAC maintenance. Hutto’s days are getting shorter as we are approaching the end of summer. And now is the time to schedule fall maintenance. It probably isn’t your favorite thing to schedule routine HVAC maintenance. However, HVAC maintenance is essential for heating systems to perform at their best, and fall is the perfect season for this. 

You may be wondering why fall is the best time for HVAC maintenance. Here are a few reasons: 

The Time Is Right for Repairs

Cooler months are ideal for scheduling HVAC system maintenance if you want your system to run at its best. Your system will have to work harder than necessary if you wait till spring when the temperature is already rising. Additionally, HVAC contractor Austin, TX, helps you prepare your HVAC system in advance for cold winter days.

Get Ready for Winter Season

It’s a good idea to conduct a maintenance check before winter, as the summer is coming to an end. Problems can arise anytime. However, a routine maintenance check allows any operational issues to be addressed ahead of time, rather than causing the system to fail in the middle of winter.

Grande Air Solutions can help your heating system get ready for winter with fall maintenance by repairing and cleaning its components. 

Prevent Toxic Gas Leakage

The maintenance of your HVAC system before winter will save you money while protecting your family from harmful gases, such as carbon monoxide poisoning. Carbon monoxide poisoning can occur from leaky ducts if they are not repaired immediately. The presence of carbon monoxide in your home poses a serious health threat if you do not have a functioning carbon monoxide detector.

Carbon monoxide can be lethal if it leaks from your ductwork or furnace, which is why it’s crucial to have them repaired before winter begins. 

Clear Out Your Home Air 

You and your family will spend a lot more time indoors during the winter, which makes indoor air quality even more critical. You can ensure that your HVAC system is clean and debris-free this winter by scheduling maintenance with air conditioning repair Hutto service for the fall.
