Why It’S A Bad Idea to Install The Wrong Size Central Air
It is important to understand exactly why it is not advisable to install the wrong size central air, whether too big or too small.
Table of Contents
An air conditioner’s primary purpose is to cool down your home. However, using one that doesn’t match the square footage of your home will struggle to keep a room at a comfortable temperature. The right-sized air conditioner will give you the best results in comfort, performance and energy efficiency.
Air Conditioner Ratings
Air conditioners are typically rated in two ways: cooling capacity and energy efficiency.
Variables That Might Impact the Size of Air Conditioner
The main factor for choosing the right sized air conditioning system is the square footage of your home. However, there are some other variables that come into play which can affect how efficiently your system can cool.
How to Calculate Size
To calculate the size of the unit you will need, you will need to know the square footage of the room or house. To find the square footage, multiply the length times the width of the rooms in your home, then add them together. Once you have the square footage, multiply it by 25 to get the BTUhs needed to cool your space.
Existing Ductwork
The size of your air conditioning unit must be compatible with your ductwork. The wrong sized ducts will cause similar problems to having an improperly sized AC unit for your square footage. Improperly-sized ductwork puts too much pressure on your unit.
HVAC Pros
Although it’s important to understand how to pick the right size air conditioner for your home, an HVAC professional will perform all the calculations necessary for maximum efficiency.
Types of air conditioning systems
Before sizing your air conditioner to your home’s needs, determine what type of system you want to install. There are a variety of cooling systems available, but we’ll cover the three primary styles below. (Looking for how to properly size a window AC ?)
How many BTU per square foot?
A BTU, or British Thermal Unit, is a rating that measures the energy your AC uses in one hour to remove heat from your indoor air. The BTU of your HVAC system should be based on the square footage of your home, insulation quality, climate zone, and ductwork.
Manual J calculation
A Manual J calculation is like an energy audit of your home. Who performs the Manual J calculation can vary depending on your region. In some instances, the HVAC company will complete the audit. It’s also possible for a general contractor or energy consultant to complete the work.
AC climate zones
While the square footage and makeup of your home will give you great direction on sizing your HVAC unit, we can’t forget climate.
Best HVAC size for your home
Choosing the right size air conditioning system for your home doesn’t have to be complicated.
Why does my air compressor short cycle?
If the system you install is too large for the space, it will short cycle. In other words, the compressor will not run long enough to dehumidify the space and will limit your comfort. In addition, it will cycle on and off more frequently, increasing operating costs and reducing the system life.
When to use the lower number or higher number?
Use the lower of the two numbers if your home is well insulated and the higher number if it is older or poorly insulated. (Hint: Use the larger of the two numbers above if you're unsure of your home's insulation)
Does the manufacturer list the size of an air conditioner?
The manufacturers do not list the air conditioner size on the unit. The system capacity will be coded into the model number of the outdoor unit. For example, model GSX140241K is a 2 ton unit.
Why HVAC size Matters
The right size air conditioner for your home will work much more efficiently. When your system is too large or too small, you may battle an uncomfortable indoor climate and higher energy costs.
Step 1: Air conditioner types that best fit your home
There are three primary types of air conditioners, all which cool in a very similar way. Your home likely has one of the following systems: ductless AC, packaged air conditioner, or split-system air conditioner.
Step 2: Review ratings for the HVAC size you need
Once you’ve determined which type of AC is best for your home, research the ratings of the style you prefer. Air conditioners are usually rated based on their energy efficiency and cooling capacity. As you set out to answer “what size AC unit do I need?” it’s a good idea to be familiar with how those two components are represented.
Step 3: Estimate the right AC size for your house
How your desired AC unit is rated is just one element to consider when choosing the right size HVAC. In order to get optimal results from your HVAC investment, rely on the trusted advice of an American Standard Customer Care dealer. Our independent dealers can help you determine the best size HVAC for your home based on more than square footage.
Step 4: Request an energy audit and Manual J calculation
You may also consider having a Manual J calculation completed through an energy audit. Many utility companies offer these audits and reports for free, but if not, it’s possible to hire an HVAC dealer or energy auditor to complete the inspection.
Step 5: Match your square footage to an HVAC size chart
While a professionally trained American Standard Customer Care dealer is the best way to determine the right size AC for your home, this chart can begin to give you an idea based on your home’s size.

How many BTUs does a 1 ton AC unit cool?
If you have a one ton AC unit, it means it has the ability to cool 12,000 BTUs an hour. Residential central air conditioners come in a range of sizes from 1.5 ton to 5 ton models. If you need a unit that has more than 5 ton cooling capacity, then it is likely you will need multiple AC units. Hang on…..
Why is an air conditioner bad?
There are numerous reasons why installing an air conditioner that is too powerful is a bad idea: 1 The upfront costs to purchase the unit are higher 2 Larger units use more electricity (even when working less) 3 The number of times that the unit will turn on and off is much higher, causing wear and tear and higher maintenance costs 4 House remains humid because the unit does not run long enough to remove the moisture from the air
What is a BTU?
BTUs (British Thermal Units) British Thermal Units is a measurement of heat. 1 BTU is the amount of heat required to increase the temperature of 1 pound of water at sea level by 1°F.
What is manual J load?

Pricing Accuracy
You will get 3 price points: Low, Mid-Range and High. These price points do not imply that low price equals low quality and vise-versa. In reality, you can get the same job done, at different cost, depending who you hire.
How to calculate HVAC load

Multiple systems for homes over 3900 square feet
Most residential Cooling and Heating systems are designed for homes SMALLER than 3500 square feet. However, they would still perform rather well in ah house that is 3900 sq. ft.
Understanding System BTU Load
As mentioned above, we use a more “real life” formula for calculating BTU load (using simple Manual J calculation), which is more aggressive compared to what you would get from an HVAC contractor or an equipment distributor.
STEP 1: Determine how many BTUs of heating and tons of AC you need
The best way to determine the perfect HVAC unit size is to have a Manual J calculation done for your house. The Manual J calculation is the most precise measurement available because it considers factors like:
STEP 2: Decide which unit to buy
Now it’s time to work with an HVAC dealer to learn more about the heating and cooling products they offer. Sometimes the dealer may not have your exact BTU size — but don’t worry. If your BTU requirement is between sizes, simply go with the bigger unit. For example, the Manual J calculation may say you need 25,000 BTUs for cooling.
