Buying a New AC System? One Size Does Not Fit All.

Mini split air conditioner

In the world of air conditioners, it’s possible to have too much of a good thing.

Every home is different, and a bigger AC isn’t always better. The size of the air conditioning system you need for your home will hinge on several different factors.

If you’re asking yourself, “What size air conditioner do I need for my home?” read on to find out how to answer that question.

What size air conditioner do I need for my home?

When deciding the right AC size for your property, your HVAC technician will look at several different factors, including:
  • HVAC units

    The size of your living space

  • The age of your home
  • Your insulation: how much is there, and how good it is
  • The area of exterior walls exposed to the sun
  • Your windows: how many you have, when they were installed, their condition, and which way they face in relation to the sun
  • Whether you have trees and shrubs that provide shade
  • Your ductwork and ventilation system

Why is this important?

So that’s how we answer the question of “What size air conditioner do I need for my home?”

But why is the size of the air conditioner even a factor?

Air conditioners are built to last a long time, in most cases more than 10 years. But far too many homeowners buy the wrong size system, either because they weren’t aware how important finding the right size is, or because their HVAC company didn’t do a consultation.

An AC unit that’s too big will shut on and off too quickly, while a system that’s too small for your home won’t give you the comfort level you want.

When you have the wrong sized air conditioner unit, you can run into these type of problems:
  • HVAC technicianLike we noted above, a unit that’s too big will cycle on and off over and over. This can strain your system, and lead to frequent repairs.
  • Improper cycling also means less energy efficiency. If your system never gets the chance to rest, you’ll see that extra energy on your next bill.
  • Finally, a system that’s the wrong size won’t heat or cool your home very well, which means you and your family will never feel quite comfortable.

Let’s talk tonnage

Air conditioners are rated in terms of tons of cooling capacity, where one ton of cooling is the same as 12,000 BTUs per hour.

Two AC units might have the same tonnage, but that doesn’t mean they have the same energy efficiency, or SEER rating (Seasonal Energy Efficiency Ratio).

When you’ve found the right tonnage size for your home, check the SEER ratings and see which one works for your budget. The greater the SEER, the less energy it will use.

The cost of cooling your home can be substantial, so it’s important to have the right sized AC unit to ensure your family’s comfort doesn’t exhaust your household budget.
