A Buyer’s Guide To Garden Office Air Conditioning

Compared to other options, garden offices and garden office sheds are the most comfortable year-round office alternatives.

With a little bit of insulation, you can stabilize the temperature inside the area. The temperature stays at a comfortable level during the hot summer days and cold winter nights. But what if insulation alone is not enough to endure the extreme temperature changes?

If that’s the case, there’s only one way to control the temperature of your garden office: air conditioning. 

Keeping a comfortable workplace is essential, especially if you’re working at home. According to the American Psychological Association, a comfortable workspace can reduce work-related stress both physically and mentally.

One effective way of achieving workplace harmony is by maintaining a specific comfortable temperature, which can only be done using air conditioning or heating. Adding AC in your small office is a great idea to raise productivity. 

Before buying, you need to know what kind of AC system is the best and most efficient for your office.

Your AC system should be durable, effective, and doesn’t use a considerable amount of energy. In this article, you will know more about ACs and what type is the best for your space. #

7 Factors To Consider Before Buying Air Conditioning For A Garden Office

Just like any other electronics, there are different models and capabilities designed for each scenario and case. Before buying your unit, here are the seven factors you need to keep in mind to get the best value for your money. 

1. Types Of Air Conditioning

Did you know that there are a handful of AC system types?

Since an AC system can be considered an investment in your home, going big is better than going cheap. But “going big” doesn’t mean getting the most expensive. It’s about getting the best AC type for a designated space and achieving the reason why you need one in the first place. 


  • Window-Mounting Air Conditioners – also known as “window units,” these ACs are best for any enclosed single room. These units are often used for offices, business rooms, and even rooms at home. What makes this a great option is its numerous features, such as digital control boards and even heat modes. However, the dripping from the AC can damage structural materials, especially wood. 


  • Central Air Conditioners – is the best option for wide-coverage heating and cooling. This can cool or warm up multiple rooms and large areas without installing various devices. It works by delivering regulated air via ducts. These ducts need to be installed in your home before the device can even work. But once these ducts are installed, monitoring and controlling temperature are easy and fast. 


  • Portable Units – these units are self-contained and can be powered without installation. Hence, you can move this unit from one area to another. In principle, portable units work similarly to window units. Once powered, it pumps up cooler air in the area and sucks out warm air via an exhaust funnel. 


  • Ductless Mini-Split Air Conditioners – are for houses with no ducts installed. Like the window unit and portable unit, ductless ACs can only regulate one area. It has both an outdoor and an indoor component, which is connected via tubing. The air will circulate from both components and will be cooled down by a refrigerant installed in the tubing. 

Overall, if you have a standard-sized garden office, the best option is the Ductless Mini-Split air conditioner. These ductless units can be installed without tearing down the wall or a window.

In addition to these benefits, ductless units are also great when it comes to the other factors listed below. 

2. Size Of The Room

The size of the room is one of the important considerations in choosing the best AC unit. According to Consumer Reports, small rooms (100 to 300 sq ft) requires about 5,000-6,500 BTU while a large living room (350-650 sq ft) needs 9,800 to 12,500 BTU. For garden offices, an AC unit with at least 5,000 BTU is a great start. 

3. Energy Consumption

Just as the previous item on the list had demonstrated, energy consumption grows bigger with area coverage. If you are conscious about your electricity consumption, you must first check the Energy Efficiency Rating or EER of a product. A higher rating means higher efficiency in saving energy, which means that you save money from your energy bill. Aim for at least an 8.5 EER rating, but get the model with EER 11.2 if you found one. 

Take note: a high EER rating can cause a higher price tag, but the long-term energy savings are usually worth it.  

4. The Cooling Factor

Ideally, if you’re purchasing a new AC, you would want a unit that uses the least energy while giving the best air quality and cooling. All of these should be met without degrading the quality of air being pumped inside the structure.

For this category, you might have to rely on reviews and brand quality. 

5. Cost And Durability

AC systems are one of the most expensive things you can buy for a home or a home office. It is reasonable to get the best option which is within your buying budget. Expect that buying an Air Conditioning system will cost you hundreds or thousands of money. 

If you want improved durability and quality, it might be better to save money and spend on a more expensive unit that fits in your area. You can avoid any problems or inconveniences brought upon you by using cheaper and shady alternatives. 

6. Installation

Installation can either be a walk in the park or pain in the neck when it comes to AC systems. In most cases, you might need to contact a professional to install the unit (and ducts) for you. For users who don’t want to deal with complicated installations, it’s better to get a simpler type of AC.

As for garden sheds, you can go for window-type or ductless split type air conditioners for easy installation.

Most tools and equipment needed are usually a staple in any household (drills, screwdrivers, power tools, etc.)  However, you might need to rent or borrow tools such as an SDS drill for the tubing installation, if you don’t have one.

Calling a professional is recommended if you do not have any experience in this kind of stuff. 

7. Your Location

The location of the structure will play an important part in determining whether you need to focus on heating or cooling. For areas, wild mild weather changes, insulation, and proper ventilation are enough to keep the space comfortable all year-round.

In locations with heavy winter, a decent heater might be a better option. Places with dry climates will benefit from year-round air conditioning. 

The Best Air Conditioning Option For Garden Office

The best option for the Garden office AC is going ductless. Since you’re only cooling down a small room, you don’t have to go big and get a heavy-duty AC system. Ductless mini-splits are great for easy installation and great customization, since you don’t have to install them in a window.

Although it is hard to conceal, the indoor component is small enough, that you can integrate it into the decor theme without any major problem.

Newer split-type ductless ACs also have a good heating solution, which is great for keeping yourself comfortable during a frosty winter day. Since you’re only going to run the machine through a small room, it doesn’t require a lot of energy to maintain a certain temperature requirement.

Just make sure that your room is also well-insulated (walls, roof, and flooring). This way, your AC doesn’t have to put on additional work to maintain the room temperature. 

Ductless ACs have a lot of advantages, but their major drawback is the price. It can take you up to $1,500 to $2,000 for a single system (that produces 12,000 BTU per hour). If you don’t have the budget to get a ductless AC, your second-best option is to use window-type ACs. 

These products can cool down bigger sheds and are usually installed on windows. However, noisy operation and the potential dripping (that can destroy untreated wood) is a big turn-off for a lot of people. And since you install it through a window, this might affect overall ventilation in the room.
