How Much Cooling Do You Need in a Server Room? 

Several factors might determine exactly how much cooling you need in the server room. To determine this, you have to calculate the BTU in the room using the following formulas:

  • Room Size BTU: Width x Length x 337
  • Total Windows BTU: South Windows + North Windows
  • Number of Occupants BTU: Number of People working there x 400
  • Total Equipment BTU: Total Equipment Wattage x 3.5
  • Total Lighting BTU: Total Lighting Wattage x 4.25

Once you have calculated all of the British Thermal Units, you need to add them all up. This way, you will find out exactly how much server room cooling you need. By getting the right product, you should be able to bring the temperature to a comfortable level.

Types of Best Server Room AC Systems 

Depending on your server room’s size or functionality, you may want to choose between different types of server room air conditioners. Whether you have a small server room or one with multiple hot spots, here are the types that you may want to consider.

  • Spot Cooling Air Conditioner

A spot cooling portable air conditioner is well-sought for lowering the temperature in server rooms. These portable AC units may be easily placed in the area that does not get enough cooling. They are the perfect choice if you have hot spots in your server room.

These portable devices may be placed close to closets, server racks, or any other area that needs cooling. They are also a great choice if you are looking to cool a high-priority server rack over a smaller amount of time.

  • Wall Mount Air Conditioner

A wall-mounted room air conditioner can also prove to be a good choice, mainly if the room in question is not very small. It is the perfect choice for medium to large servers.

Also referred to as mini-split, ductless air conditioners, these units can cool a server room evenly, without additional expenses or hassles. However, you may still want to hire some air conditioning engineers if this is your first time installing such a unit in your server room.

  • Ceiling Air Conditioner

Also referred to as a cassette air conditioning unit, this model is the perfect choice for server rooms, particularly when you don’t have a free wall to hang it on. The only thing you have to do is prop it on the ceiling instead of the classic options.

Many people owning server rooms, including IT professionals, prefer this type of air conditioning system. This is because many server rooms are lacking in floor space – rendering even portable air conditioners useless. With this type of air conditioning system, you may evenly send cool air throughout the servers.

Factors to Consider when Choosing Air Conditioner for Server Room

Several factors need to be taken into consideration when looking for air conditioners for server rooms. Here is what you’ll have to keep in mind.

  • Coverage

When choosing an air conditioner for a server room, you need to make sure that the heat load can handle the entire area. No matter if you have a small server room or a large one, you need to pick something with the appropriate amount of cooling power.

Bear in mind that if you go for something with higher coverage, you would also want to make sure it has a decent energy rating. Look for air conditioning units for your servers that have an Energy Star rights reserved label.

  • Portability

If you have other rooms aside from your server room in need of air conditioning, then you might want to get a portable unit.

Portable air conditioners will often be small in size and have caster wheels so that you may move them. They are efficient while still saving space.

  • Installation Requirements

Regardless of its type or whether it’s ductless or wall-mounted, a server room air conditioner will need a place to vent. It is essential to ensure that the area you vent it through is vacuum-sealed.

Also, check whether it comes with a single or a dual hose. The latter might have a slightly lengthier installation process, but ACs often have better cooling power too.

  • Noise Levels

Every server room air conditioner will make a bit of noise, whether you choose a ceiling model, a wall-mounted one, or one for spot cooling. It would help if you looked into air conditioners for your servers that have a low decibel level with that in mind.

This way, even if the noise gets out of the server room, it won’t turn out to be bothersome. Plus, you’ll be thankful for the reduced noise level if you work in a data center’s server room.


The Pioneer air conditioner is certainly the best overall choice, as it has multiple features while fetching a fair price. However, if you are on a tight budget, you may want to consider the Black + Decker model since it has most of the essential products without bells and whistles. The De’Longhi may also serve you well due to its very quiet nature.

In the end, you need to pick the type and model that works best for your purposes. Whether you are looking for a portable model or wall-hung model or want a quiet AC, go for a unit that meets your requirements. If you have any queries, feel free to contact us.
