Summer is coming, which means warehouses and distribution centers all over the country will be firing up their air conditioners to keep their products and employees cool.

In this blog post, we will answer all the questions you have about warehouse air conditioners. We’ll cover the different types of AC systems, how to size your system, ventilation methods, and more.

Can A Warehouse Be Air Conditioned?

The short answer is yes, a warehouse can be air conditioned – but there are a few things to consider before you make the investment. First, you’ll need to decide how much of the warehouse you want to air condition.

If you only need to air condition a small section, you may be able to get away with a portable air conditioner. However, if you need to air-condition the entire space, you’ll need to install a central air conditioning system.

Another thing to consider is the type of air conditioning system you’ll need. Industrial air conditioners are designed to cool large spaces, so they may be a good option for your warehouse.

However, they can be expensive to install, so you’ll need to weigh the costs before making a decision.

Why Do Warehouses Not Have Air Conditioning?

One of the most common questions we get asked is why warehouses do not have air conditioning. The short answer is that warehouse air conditioning is sometimes simply not necessary. However, there are a few factors that contribute to this.

First, air conditioning can be expensive to install and operate. Second, air conditioning can actually make some types of warehouse storage, such as for food or chemicals, more difficult. And finally, many warehouses are located in areas where the climate is not conducive to air conditioning, such as in cold climates.

While there are some challenges to air conditioning warehouses, it is something that is being considered more and more as technology improves and costs come down. In the meantime, warehouse operators must rely on other methods to keep their facilities cool, such as using fans and insulation.

How Do You Size An Air Conditioner For A Warehouse?

When choosing sizing warehouse air conditioners, you’ll need to consider the unit’s size, capacity, and efficiency. The size of the air conditioner will determine how much cooling power it has, while the capacity determines how much area the unit can cover. The efficiency rating will tell you how much energy the unit uses.

To choose the right air conditioning system for your warehouse, there is a simple formula to find the perfect unit for your needs.

  1. Determine the square footage of the space you need to cool (calculation assumes 8 ft ceilings – if you have higher you will need a more robust system)
  2. Divide the square footage by 500
  3. Multiply this number by 12,000 (this will give you the BTU required to cool the space)
  4. Add 380 BTU times the average number of employees that work in the warehouse (For 380 x 10 workers on an average day, you would add 3,800 BTU to the number from Step 3)
  5. Add 1,000 BTU for each window

Since central air conditioners are rated in tons, you will need to divide your final number by 12,000 again to get the tons of the system that you will need to cool the warehouse space.

Sizing Warehouse Air Conditioners Sample Calculation

  • 5,000 square foot warehouse with 8 ft high ceilings
  • (Divide by 500) = 10
  • (Multiply by 12,000) = 120,000 BTU
  • (Add 10 employees x 380 BTU) = 123,800 BTU
  • (Add 5 windows x 1,000 BTU) = 128,800 BTU system required
  • (Divide by 12,000) = ~11 ton air conditioning system required

How Much Does An Air Conditioner Cost For A Warehouse?

As the summer heat sets in, you may be wondering how much it will cost to keep your warehouse cool. Warehouse air conditioners come in a variety of sizes, so the cost will depend on the size of your warehouse and the type of air conditioner you select.

Generally, warehouse air conditioners start are priced by the square foot. If you have a standard, single-room warehouse, you will likely pay $3 to $4 per square foot including installation costs. However, if you need a large unit, the price can double. This is because larger units with more zones are sophisticated and will require much more BTUs.

For a 3,000-square-foot warehouse, you can expect to pay around $10,000. If you have an even smaller warehouse, you may be able to get by using a portable warehouse air conditioner, which can cost less than $1,000.

How Do You Ventilate A Warehouse?

When it comes to warehouse ventilation, there are a few things you need to keep in mind. The size and layout of your warehouse will play a big role in determining the best ventilation system for your needs.

You’ll also need to consider the type of materials you’ll be storing in your warehouse and the potential for fire hazards.

The best way to ventilate a warehouse is to work with a professional to design a custom ventilation system that meets your specific needs. But here are 7 tips you can follow to ensure your warehouse is properly ventilated:

  1. Remove hot air by opening windows and using fans
  2. Switch off machines that are not in use to stop producing heat
  3. Practice night purging by using cold night air to cool the warehouse
  4. Reflect the sun’s rays by installing a white roof
  5. Make sure the warehouse is adequately insulated
  6. Install fans to keep air moving and remove fumes from machinery
  7. Use warehouse air conditioners to control humidity

Do All Portable Air Conditioners Need To Be Vented Out Window?

Portable warehouse air conditioners are a great way to keep cool without having to install a window unit. But one question that often comes up is whether or not portable air conditioners need to be vented out the window.

The answer is that it depends on the type of portable air conditioner you have. Some portable air conditioners can be vented out the window, while others don’t need to be. Units that don’t need to be vented typically have a reservoir that collects the water that condenses on the cooling coils.

So if you’re wondering whether or not your portable air conditioner needs to be vented out the window, the best thing to do is consult the owner’s manual.

What Is Normal Warehouse Temperature?

The normal temperature for a warehouse is typically between 68 and 72 degrees Fahrenheit. This temperature range is comfortable for most people and helps to prevent heat stress.

In addition, it helps to keep stored products at a consistent temperature, which can prolong their shelf life. Of course, there are times when the outside temperature may be too hot or too cold to maintain a comfortable warehouse temperature.

In these cases, you may need to use warehouse air conditioners or heating to maintain a comfortable environment for your employees and your stored products.

What Do Warehouse Exhaust Fans Do?

Warehouse exhaust fans play an important role in keeping warehouses safe and comfortable for workers. Exhaust fans help create a healthy and productive work environment by circulating air and removing contaminants.

There are two main types of warehouse exhaust fans: wall-mounted and ceiling-mounted. Wall-mounted fans are typically used in smaller warehouses, while ceiling-mounted fans are used in larger warehouses.

Warehouse exhaust fans come in a variety of sizes and capacities, so it’s important to choose the right fan for your needs.

In addition to circulating air and removing contaminants, warehouse exhaust fans can also help reduce noise levels. By redirecting noise upwards, away from workers, exhaust fans can help create a quieter work environment.

If you’re looking for a way to improve the safety and comfort of your warehouse, consider installing a warehouse exhaust fan.

Can You Air Condition A Metal Shed?

It’s a hot summer day and you’re working in your metal shed. The heat is unbearable and you start to wonder: can you air condition a metal shed?

The answer is yes, you can air condition a metal shed. However, it’s not as simple as installing a window unit air conditioner. Metal sheds are not well insulated, so you’ll need to take some extra steps to ensure that your air conditioner will be effective. Here are 2 tips to make sure you air condition a metal shed properly:

1. Install an air conditioner that is specifically designed for metal sheds. These air conditioners are more powerful and have better insulation, so they will be more effective at cooling your shed.

2. Make sure your air conditioner is properly installed. This means that it should be securely mounted to the shed and that the ductwork is properly sealed.

The air conditioner should be able to maintain a comfortable temperature inside the shed, even when it’s hot outside. By following these 2 tips, you can ensure that your air conditioner is installed correctly and that your shed stays cool and comfortable all summer long.


Air conditioners are a necessary part of warehouse operations. They help to regulate the temperature and keep the air quality at a suitable level. There are a variety of air conditioners on the market, and it is important to choose the right one for your needs.
