They are functionally different from fans, because fans don’t actually cool air, but only make it feel cooler by moving it around.  The advantage of air conditioners is that they increase comfort levels during hot weather, but they can also present various disadvantages.

This video shows the advantage and disadvantage of air condtioner.



Most people use air conditioners to stay more comfortable in their homes or offices during hot and humid summer weather. Under extreme conditions, air conditioners may keep elderly and other vulnerable people safer from heat-induced health problems. Air conditioners are used in many commercial settings not only for increased comfort but for decreasing heat stress on delicate machinery such as computers, and reducing food spoilage in grocery stores and restaurants.

Prevents Dehydration and Heat strokes

Being exposed to excessive heat for long periods can cause dehydration. This is because high temperature leads to profuse sweating and makes your body lose water. If you fail to replenish this lost water, the result will be dehydration. Since air conditioners reduce sweating, they can minimize the risk of water loss and dehydration.

Heat strokes are another problem that excessive heat can cause. This is because too much heat can make it difficult for the body to regulate its temperature. Failing to treat this problem early enough can cause damage to the brain and other organs of the body. Since air conditioners reduce the temperature of the air, they can be helpful in preventing heat strokes.

Improves the Quality of Air

Air conditioners can significantly improve indoor air quality and create a much healthier atmosphere. This is because they are capable of flittering out pollen, dust, and other allergens present in the environment. By reducing humidity, air conditioners can check the growth of mildew and mold.

Helps to Reduce Asthma and Allergies

Air conditions can help to filter as well as disinfect the air that we breathe. This can help to reduce the risk of asthma attacks and allergies by removing pollen and dust, and also preventing the growth of mildew and mold. Being exposed to mold is one of the main factors that increase the risk of asthma attacks, allergic reactions, and other respiratory issues. The fact that we close our windows while using air conditioners helps to prevent the entry of environmental allergens, bacteria, and dust.


Air conditioners use a lot of electricity. This creates both financial disadvantages for the people who have to pay for the power, and more generalized environmental disadvantages caused by power production. Because a large percentage of electricity is created by coal-burning power plants, air conditioning contributes indirectly to the release of greenhouse gases and other pollutants. In addition, according to The Independent, spending too much time in an air-conditioned environment can contribute to health problems such as asthma, tightness in the chest and other respiratory ailments.

Skin Dryness

Spending increased amount of time in an air-conditioned room can make your skin lose its moisture, thereby becoming sensitive and dry. It can also cause irritation and dryness of the mucous membrane.

Aggravation of Respiratory Problems

A sudden change in temperature has shown to exacerbate the symptoms of various respiratory diseases. Fortunately, you can significantly reduce the risk of this problem by setting a higher temperature and decreasing it gradually.

Respiratory Tract Infections and Allergies

Not cleaning the air conditioner can cause the buildup of dust, bacteria, and pollen in the air filters. This will significantly increase the risk of asthma attacks and respiratory tract infections.

Getting an air conditioning unit installed in your commercial property can be a bit of an undertaking. It’s not as simple as changing the brand of tea bags in the kitchen – although the impact it can have on workers can be just as significant as this. Whilst air conditioning can be a godsend during those hot summer months, there are also a few negative aspects you may not have considered.

Before you decide whether to invest in a air conditioning unit, you should evaluate the pros and cons so you can make the best decision for your business. Here are the pros and cons of investing in an air conditioning unit for your workplace:

Pros of Air Conditioning

  • Prevent heatstroke

The most crucial advantage to an air conditioner in the workplace is preventing your staff from overheating. Too much heat can be detrimental to people’s concentration and comfort, but in extreme temperatures, your staff could also be in danger of heat stroke. This is due to the heat making it difficult for the body to regulate its temperature. Heat strokes can be dangerous and cause people to become unconscious or even, in extreme cases, cause organ failure.

With an air conditioner, temperatures can be reduced to help prevent heat-related illnesses from occurring. If your workers are spending all day inside one building, keeping that building at a cool, comfortable temperature is essential during the summertime.

  • Improve air quality

Air conditioners have filters that catch dust and pollen in the air, which can lead to an increase in airflow quality. They filter out allergens that can be detrimental to people’s health, to create a much healthier atmosphere. Additionally, given that the windows will be kept closed while the air conditioner is on, you will keep pollen particles out that can trigger allergies.

However, the clean air is only a benefit provided the filters remain clean and maintained. When filters get too clogged with dust, it could have the opposite effect as the particles are circulated around the space, so always ensure you check the filters regularly.

  • Consistent temperature

The UK summer can be incredibly unpredictable; one moment it’s pouring with rain, and you wonder whether summer has already ended, the next it’s dazzling sunshine and the temperature is climbing into the 30s. With an air conditioner, the temperature can be set to a specific level, keeping the workplace at a constant, comfortable temperature that is immune to the fluctuations of the unpredictable UK weather.

Cons of Air Conditioning

  • Skin dryness

While air conditioning can be beneficial to health with the circulation of filtered, clean air, it can have a detrimental effect on the skin in the form of dryness. This is because an air-conditioned room can cause the skin to lose its moisture, causing it to become dry and possibly even irritated. This can be addressed by having hand cream alongside the soap in bathrooms for employees to use to retain moisture in their hands.

  • Higher energy bills

Even though air conditioners are not as expensive to run as you might think, they will still increase your energy bills compared to not having an air conditioning unit. So, make sure you consider this when thinking about purchasing one, including how often it’s likely to be running so you can get an estimate of how much it will add to those energy bills.

  • Maintenance

Air conditioning units are intricate pieces of machinery, and while they are incredibly easy to operate once they’ve been installed, you will need a professional brought in if anything goes wrong, or to perform an annual check-up to ensure everything is in working order. This will need to be factored into your costs of owning an air conditioning unit.

Fortunately, some suppliers offer service and repair of air conditioning units, like Heritage Heating and Cooling. You can sign up to our service and repair cover at different levels to receive the likes of an annual service, breakdown cover, parts inclusion and an engineer guarantee in twelve hours.

Final Considerations

An air conditioning unit can add some serious benefits to your workplace, most notably an increase in employee satisfaction from the added comfort of a suitable temperature. Your workers will have an increase in their productivity and job performance. However, always make sure you factor in the costs of buying, running and maintaining an air conditioning unit before you decide to make a purchase.
