How to clean air conditioners at home easily and effectively without calling a mechanic

Why is it necessary to clean the air conditioner?

Many families often skip the cleaning and maintenance of the air conditioner in the house. This actually causes many bad effects on the air conditioner, which can make the machine not work as well as when it was purchased. Why does that happen, the following reasons will help you answer your question:

1. The air filter is dirty

In each air conditioner is equipped with filter membranes capable of filtering dust when cold air is blown through. This organ is like a human lung, helping to eliminate bacteria and allergens in the air. Thereby bringing fresh, cool and quality air to you.

When using the air conditioner for a long time without cleaning, the air filter will definitely accumulate a lot of dirt. This will reduce the ability to clean the air, indirectly causing you and your family members to suffer from respiratory diseases. Therefore, it is necessary to clean the air conditioner, especially the air filter, which should be done regularly.

2. Reduced cooling capacity

It is because dirt accumulates and clings to the air filter more and more over the years. Therefore, it will be difficult for the cool air to pass through the filter and blow down your room. This will cause the air conditioner to reduce its cooling capacity, making you uncomfortable and frustrated.

3. Reduces the life of the air conditioner

Dirt that accumulates in the air conditioner for a long time also reduces the life of the machine. They will cause the air conditioner to become hotter, more prone to water leakage, and easy to short circuit the electronic circuit board. From there, it costs you time to repair or even replace damaged components.

4. Expensive, wasteful

If you do not clean the air conditioner regularly, it will not cool at its best. From there you will have to reduce the temperature as low as possible to make the air conditioner cool more optimally. This will cause the machine to operate at a large capacity, which consumes electricity. Your electricity bill also increases gallopingly.

How often should the air conditioner be cleaned?

From the above reasons, you need to clean the air conditioner regularly to help increase the life and workability of the device. But many people will have the question, how often does it take to clean the air conditioner? You can refer to the time as follows:

– For family air conditioners: You should conduct periodic cleaning at least every 3-4 months if you often use them. Or clean every 6 months if you use less.

– For air conditioners of corporate offices, restaurants, and cafeterias: You should conduct periodic cleaning at least every 2-3 months. Because these devices work almost continuously all day, there will be a lot of dirt accumulation over time.

– For air conditioners of factories and factories: You should conduct periodic cleaning at least once every 1-2 months. Because factories and enterprises are places where air conditioners are used 24/24. Over time, the life of the device will be greatly reduced as well as more susceptible to dirt.
