What You Need To Know About The Number Of BTUs Required For Your 30×40 Shop

What You Need To Know About The Number Of BTUs Required For Your 30x40 Shop

If so, what size should you use? Do you want to instal an air conditioner in your shop but are unsure? How much BTU are required for a 30×40 space then?

The shop’s space is 1,200 square feet if it is 30 feet by 40 feet. Given that there are 20 BTU per square foot, this size shop requires 24,000 BTU.

This time, we’ll go through how to calculate a BTU to determine the size of air conditioner you require. We’ll go through some crucial information with you.

Number Of BTUs Required For A 30×40 Shop

The thermal unit known as BTU is used to calculate how much heat is required to increase a pound of water’s temperature by one degree Fahrenheit.

See the solutions on how to determine how many BTUs you need for a 30×40 shop below.

To start, multiply 30 by 40 to get the area, which is 1,200 square feet. Now, 20 BTU is the usual recommendation for a one-foot space. Consequently, multiplying 1,200 square feet by 20 BTU results in 24,000 BTU. Therefore, 24,000 BTU are required for a 30×40 shop. Verify the following calculation:

How Should I Use The BTU Calculation?

Finding the appropriate size air conditioner to utilise is the simple solution. Finding the tonnage will help you determine the size of air conditioner you need because BTU plays a significant role in determining how much the temperature in an area changes.

The term “tonnage” describes the ability of an air conditioner to cool down a space; 1 tonne can remove 12,000 BTU of heat. For instance, using our earlier computation, we arrived at 24,000 BTU. To get the tonnage, divide 24,000 BTU by 12,000 BTU.

As a result, the answer is two. A two-ton air conditioner is therefore required for a 30×40 shop, or an area of 1,200 square feet. Check out the precise calculation below:

  • 24,000 BTU divided by 12,000 BTU (or 2-ton air conditioning unit)

Additionally, 12,000 BTU is equal to 600 square feet of space. So, multiplying the area’s square footage by 600 is another method for calculating tonnage. On how to do it, see below:

  • 1,200 sq. 600 square feet times 2 feet (or 2-ton air conditioning unit)

Why Are Tonnage And BTU Important?

Tonnage and BTU are both significant factors for HVAC systems. They serve as the most important gauges of how much a suitably sized system may change the local temperature. You should be aware of further information concerning this significance, though. Look over the list below.

The Appropriate AC size
You may establish the tonnage and the appropriate air conditioner size by computing the BTU. The model, features, and other factors that distinguish air conditioners also affect their cooling capacity.

For instance, you wouldn’t want to purchase a half-ton air conditioner with a capacity of 600 BTU if the area requires 24,000 BTU. similar to utilising a larger-than-needed appliance with a 24,000 BTU maximum. A properly sized unit will be important for performance and efficiency because of this.

Efficiency In Temperature
For instance, after the room temperature is appropriate for the space and pleasant, you can turn off the air conditioner. The device doesn’t have to be on all day. The parts and motors will overheat and wear out otherwise. Additionally, a precise BTU and tonnage calculation lowers the cost of your electricity bills.

Health Issues
Your health may be impacted because you require an air conditioner. Controlling air temperature and quality helps to keep the heart healthy, lowers the likelihood of illness, and lessens the impact of allergies.

Installing A Two Ton Air Conditioner

Installing a two-ton air conditioner is comparable to installing other standard air conditioners because they don’t look all that different. All you have to do is look in the product description for the tonnage. Remember that the installation procedures can vary depending on the brand, model, and kind of air conditioner.

So, take a look at the instructions for installing a split-system air conditioner below:

  1. Remove any obstructions from the wall where the indoor unit will be installed.
  2. The wall’s dimensions. You can take into account at least 7 feet in height and 6 to 12 inches on all sides.
  3. Mark the locations for the screw holes before mounting the plate to the wall.
  4. Drill the holes, then use screws to mount the plate.
  5. Drill the drain hose a hole that is at least three inches wide.
  6. Examine the unit’s cables and connect them in accordance with the product installation manual.
  7. To connect the drain hose and other pipes to the appliance, pull them.
  8. Install the device on the plate.
  9. Create a safe area by laying a concrete pad there, for example.
  10. Place the outdoor unit on top of the concrete pad, then secure each foot with a metal plate and rubber cushion.
  11. To connect the wires to the outdoor unit, read the manual once more.
  12. Pipes from the indoor unit should be connected.
  13. Continue bleeding the refrigerant lines in the system to produce a vacuum. The knowledge and tools of a qualified HVAC specialist may be needed for this process because it is technical.
  14. Seal the drain hose and pipes that pass through the wall with silicon caulk.
  15. Turn on the air conditioner and use the remote to test it out.

How Much Electricity Is Used By A 2-Ton Unit?

A two-ton unit should use at least 1.71kWh of electricity every hour. This equates to about 41.04 kWh daily. Therefore, you will save a lot of money by turning the device off while not in use.

A SEER Rating: What Is It?

Seasonal Energy Efficiency Rating, or SEER, is a crucial measurement in the HVAC industry that shows how much energy a unit uses in relation to the cost of your monthly payment.

Depending on the type of unit, the SEER of most air conditioners is around 14. Your model’s SEER can be found by looking at the unit label.

How Can Ventilation Be Made Better In A Small Shop?

If you own a store, it’s probable that outsiders will come and go. Air contamination may arise from this. Therefore, it’s critical to upgrade ventilation to enable the circulation of clean air. See some suggestions for alternatives to using an air conditioner below.

Implement A Mechanical Fan
A mechanical fan aids in circulating fresh air in the space. To improve the efficiency of the airflow, you can use it in conjunction with the air conditioner. A mechanical fan utilises less energy than an air conditioner, which can save costs.

Make Sure To Open Windows
To force the polluted air outside and let the cleaner air inside, you need open the shop’s windows. This is only feasible, though, provided the outside air is clean.

For instance, you can’t guarantee clean air if your store is close to a road with plenty of traffic. Opening the windows, however, at least allows for the best air exchange.

Get An Exhaust Fan Installed
An exhaust fan is a tool that pushes heated air outside, allowing cooler air to fill the space in its place. An exhaust fan, mechanical fan, and air conditioner can all be found at one location. The amount of room available for the shop will determine how much can be done, though.

Please see the installation instructions below:

  1. Mark the exhaust fan’s size on the wall after measuring it.
  2. Make a hole The pre-drilled hole for the exhaust fan can also be used.
  3. Place the exhaust fan inside the hole’s corners. To support the unit if the wall is constructed of cement, you can add a wooden frame.
  4. Use some clips to secure the wires to the wall after connecting them to the outlet.
  5. Activate the exhaust fan and check out the better ventilation.

Utilize An Air Freshener
Although an air freshener is a quick alternative to air purification, it offers little in the way of airflow. You can utilise air fresheners, especially if the store is frequently crowded with outside consumers. Additionally, it can make the area smell better and look better.


Isn’t this yet another helpful article? In which we learnt how to find the BTU and tonnage, as well as how much BTU there in a 30×40 shop. For the safety and efficiency of the air conditioner, always consult an HVAC specialist.
