Easy To Use A/C Size Selection Tool: Check the color coded map above and confirm the zone your home is in. Then, on the chart included underneath, select the square footage of your home along with the zone you're in. From there you can select one of units that will be most efficient for your home.
A lot of real science is included in the methods of calculation when selecting the right size central air conditioner for your home. For instance, one of these methods is a Residential Load Calculation.
Another method for sizing air conditioners is determining the size of the air conditioner system that's currently in place. Manufacturers normally don't list the size of the air conditioner unit but don't worry! The system capacity is almost always coded into the model number of the outdoor unit.
In most cases you can use the conversion information below to help in determining the size of your existing air conditioner system (use the system model number NOT the serial number)
18 = 1.5 tons
24 = 2 tons
30 = 2.5 tons
36 = 3 tons
42 = 3.5 tons
48 = 4 tons
60 = 5 tons
A Warning Before You Start Sizing Your Air Conditioner: Do not to make the mistake of buying an A/C that's too large! When you install an air conditioner that's too large for the space, it does what is called a 'short cycle'. A short cycle is when the compressor doesn't run for enough time to dehumidify the area you're trying to climate control. A short cycling A/C system isn't the only concern; in most cases the system will cycle on and off more often, this translates to an increase in operating costs and an overall reduction in the system's life. Proper air conditioner sizing is critical to optimize performance.
Here we will cover how to use the heating guide portion of this selection guide. You will need to use the lower of the two numbers if you know your home to be well insulated; use the higher number if your home is older and poorly insulated – be honest! It will pay off in the end. (Here's another Hint: You should select the larger of the two numbers if you're completely unsure of your home's insulation)
If you can find your furnace model number, you can skip the calculation and look up your model number to find exactly what you need. Please refer to this furnace model number decoder to help determine what you currently have. If you have issues with this, give us a call and we are happy to help.
You will then quickly multiply the correct number above by your home's total heated square footage. At this point you will have arrived at your approximate heating capacity requirement.
An example you can reference: If your home is in the yellow zone, your home is adequately insulated, and you've got 2000 heated square feet, the equation will look something like this:
2000 square feet
X 40 heating factor (from the chart above)
80,000 Btu actual output
Next, if you need to calculate the output you need on a gas furnace, simply multiply its efficiency by its listed input rating for the BTU output of heat.
An example you can reference: If a furnace is listed with an input rating of 100,000 BTU's and an efficiency rating of 80%, it would produce:
100,000 Btu input
X .80 efficiency
80,000 Btu actual output
If the same 100,000 BTU furnace has an efficiency rating of 93% it will produce:
100,000 Btu input
X .93 efficiency
93,000 Btu actual output
Seeing a pattern here? In the example above, using an 80% efficient furnace, the 2000 square foot home above would require a 100,000 BTU input furnace which will produce the necessary 80,000 BTU's output of heat.
Let's talk about all of the variables that come into play when selecting a new air conditioner system or furnace. One such Variable is your insulation, another whole set of variables being the type and number of windows in the space, number of stories in your home, the construction type, etc. All of these variables will greatly affect the required BTU's per square for both heating and cooling. A good rule to follow is if your home is well insulated and has newer style windows, you can (in most cases) safely choose the smaller size system that conforms to the specs needed for your total square footage.
Is your home two story? If the answer to that question is 'yes' it will place less of a load on the system in the downstairs floor because the second floor acts as additional insulation. If your home isn't well insulated or if it has older style windows and an obscenely high number of windows, you're going to want to select a larger system that falls within your specified square footage range. The less insulated and more windows within the environment, the more likely you will experience greater air and heat loss.

Unsure the size you need?
In this section we will help you to determine the correct size for your commercial system. It is always recommended to go with the same size equipment that you have currently however this guide will help you size for new construction or addons.
The first step is to calculate the square footage of your building or the rooms you are wanting to cool. Please note that the following calculations are based off of an 8' ceiling.
Once you have the square footage, divide that number by 500.
Next you will want to multiply the number by 12,000. This will give you the base BTU's required to cool the area.
We recommend to add 380 for each person that works in that space throughout the day. We also recommend to add 1,000 for each window and 1,200 for each kitchen.
Once you have the all of the items added up you will want to divide by 12,000. This will give you the required tonnage to cool your commercial space.
Duct work sizing is also very critical when upgrading or changing your system. We have come up with a simple guide to size your duct work. Please keep in mind that this guide is only to be used as an estimate and we would highly recommend a technician to check your duct work and ensure that the proper duct work size is used.

It is essential to ensure that the cooling capacity of an air conditioner is suited to the size of the room. As a general guideline, a cooling capacity of at least 20 BTUs per square foot of space should be chosen for larger rooms. For example, for a room that is 150 square feet, it is recommended to select an air conditioner with a cooling capacity of at least 3,000 BTUs, while for a room that is 400 square feet, it is advised to select an air conditioner with a cooling capacity of at least 8,000 BTUs.
Matching the cooling capacity of the air conditioner to the room size ensures optimal performance and efficiency. This will not only provide a comfortable living environment but also help reduce energy consumption and associated costs.
Noise levels are another important factor to consider when choosing a wall-mounted air conditioner. Units with lower decibel (dB) levels will enhance comfort by minimizing disturbance. Wall-mounted air conditioners typically generate noise levels between 50 to 60 decibels (dB). The size of the room and the distance between the air conditioner and the user can also impact noise levels.
To ensure maximum comfort, it is advisable to select air conditioners with lower decibel ratings. This will help minimize noise disruption and allow you to enjoy a more peaceful and comfortable living environment.
Choosing air conditioner models with advanced features like programmable timers, remote controls, and smart connectivity can provide added convenience and control. Programmable timers enable you to set a particular time for the air conditioner to activate or deactivate, allowing you to customize your home’s cooling schedule to suit your needs and preferences.
