There are several reasons why aircon servicing is very important.

The first one is that it ensures that your air conditioner functions at its peak especially when you want it most.

Regular servicing also improves the efficiency of your air conditioner. Experts warn that for every year of operation in which you do not service your aircon, it loses 5% of its efficiency. After 3 years therefore, the efficiency of your air conditioner will have decreased by 15%. This adversely affects its performance.

Regular aircon servicing also finds and addresses small problems that if left, could grow into much bigger problems that are more expensive to repair.

However, the encouraging news is that, with regular maintenance, you can actually recover a high percentage of the lost efficiency. According to research, regular aircon servicing will give it 95% of its original efficiency. Thus, the amount of money that you use to service your unit can be recovered very quickly in terms of reduced monthly electricity bills and reduced costs of repair. An air conditioner that is properly serviced also dehumidifies your home.

Heating and cooling professionals say that even if you do not suspect that your air conditioning unit has problems, you need to have it serviced and inspected at least once every year. This will ensure that it operates at maximum efficiency. It will be ready to cool the house in the months when you require it most.

As the air conditioning unit runs, it tends to accumulate dirt and dust in critical areas such as the air filters and the condensing coils. This can adversely affect its efficiency. The buildup of dirt and dust, if not checked, reduces your machine’s operating efficiency by 5 %. This means that that your air conditioner cannot cool the house as much as it should when clean.

Many service companies also wash the condenser of the air conditioner and this can save you a lot of headache as well as money in future. Although it is a simple thing, failing to wash your condenser could cause it to malfunction and even ruin it totally.
As a homeowner, the best thing you can do for your air conditioning unit is changing your filter. Ideally, you should change the filter at least once every 30 days.

Install It Correctly
To get the most from your window air conditioner it must be properly installed. Most units are intended for double-hung windows. If you have casement windows, you may want to consider buying a through-the-wall air conditioner. Make sure your window unit is level so that it drains correctly. And move any heat-generating devices such as a TV or lamp away from the unit.

Check Filter Location
Make sure you can easily access the filter for cleaning, something you’ll be doing frequently to keep the unit in tip-top condition.

Consider Intelligent Cooling
Some air conditioners have gotten smarter, allowing you to control and adjust them from your smartphone. You may even be able to interconnect them to other cooling units in your home.

Watch the Warranty
Some air conditioners have longer warranties than others. When you’re buying a new unit, check the manufacturer’s website for information, and ask the retailer about the warranty for the brand and model you’re considering buying.

Before you consider price and features, start by determining the size of unit you need for the space you want to cool, as well as where you’ll place the unit. The air conditioners in our tests have cooling capacities ranging from
