Aircond Service, Repair & Maintenance Tips

Air Conditioning Service, Repair and Maintenance Tips That Most Didn’t Know

As a homeowner, it’s your job to make sure that your air conditioner unit is running as efficiently as possible.

When you have your air conditioning serviced, be sure to ask the technician for maintenance tips and tricks that can help you to keep your system running well.

Typically, air-conditioning systems can last anywhere from 5 to 15 years (the average being 10 years).

Depending on a variety of factors like how the AC is used, the age of the system when it was installed, and the quality of the system (some brands are just better than others).

As stated by Suruhanjaya Tenaga Malaysia, 58% of the electricity usage in offices is from air conditioning.

So it would be wise if we can keep the utility bill low by having an efficient cooling aircond.

Though the number will be different from house usage, still an air conditioner is a hefty investment for any household. We would want to keep them running as long as they could.

Why We Need Air Conditioning Service or Maintenance

An air conditioner is an important part of your home or office premises. It keeps the temperature cool and comfortable.

It is imperative to keep the AC in good condition.

An air conditioning system can easily go wrong because of the extreme weather conditions and the lack of taking care. So, it is important to regularly perform maintenance in order to prevent any further damage.

One of the most important things to consider when it comes to the home or office aircond is maintenance.

If you don’t have any experience with maintaining an air conditioning system, then it’s better that you hire a professional to look after it for you.

The air conditioning unit, which is typically a split type for most Malaysian households, is one of the most expensive appliances to run in your home, and it’s also one of the most important due to our hot and humid weather.

If you’re planning to purchase a new HVAC system, you’ll want to be sure to take good care of them.

Did you know that a poorly ventilated aircond will cause higher electricity consumption by 5%-15%?

Early Signs That Your AC Might Need Your Attention (Maintenance)

As air conditioners are used year-round, they usually don’t get enough of a break to recover from wear and tear.

This causes them to wear out before their time and to break down completely when you need them most.

Here are a few signs that you should look out for to determine if your AC needs professional attention:

  1. AC is not cooling as they used to be
  2. You heard some “hissing” sound
  3. Outdoor unit is too quiet (compressor might not be working)
  4. Water droplets out from the casing
  5. Your wall feels “wet and moist”

It might be wise if you can take early action if you spotted some of those symptoms that we listed above before any further damage is being done.

AC Repair Cost Might Not As Economical As You Think

AC repair costs can be hard to pin down since the cost of repairing your AC depends on the type of AC you have, what’s wrong with it, and whether or not it’s covered by any warranty.

In Malaysia, it is normal to get a one-year warranty for any indoor unit and a 5 years warranty for the outdoor compressor when you buy new.

For an average-sized home, the air conditioning repair cost is usually between RM200 to RM1000.

Factors like the type of system you have (inverter or non-inverter), brand, and if you have any other issues that need to be fixed will determine your air conditioning repair cost.

Air conditioners need to be serviced and cleaned regularly to avoid problems like expensive repairs, or worse, a complete breakdown.

I’m sure we all had the painful experience of sweating through our day and night when the AC decided not to work anymore.

Those are the situation we all wanted to avoid by performing regular AC maintenance.

Repairing vs Replacement – Which Makes More Sense

The average cost to repair an air conditioner is around RM250 from our observation, and the average cost to replace an air conditioner is around RM1000 for the same 1 horsepower of non-inverter type of aircond.

A repair may seem cheaper than buying a new aircond at first glance.

We hope that our repair cost breakdown below will provide more transparency and insights for you to make a well-informed decision.

ItemPrice RangeRemarks
#1Replace PCBRM250 – RM280This is an estimation. Price may vary depends on brands and various factors.
#2Replace SensorRM160 – RM200
#3Replace CapacitorRM180 – RM200
#4Replace CompressorRM500 – RM600

However, repairing an air conditioning unit may not always be the best option because it can be costly in the long run.

This is especially true for older housing areas like Subang Jaya. The AC units tend to be the older generation and will start becoming problematic.

Take the 1hp non-inverter as the case study, we will advise the customer not to go for a repair if the cost is higher than RM500.

It may be more economical to buy a new air conditioning unit instead of repairing the old one.

We would highly suggest you replace a new one instead of repairing if the following situation arises:

1) Your AC unit is too old (More than 10 years)

2) Spare part is no longer available or it’s hard to find

3) Repair cost is high

So, in all the cases above, it would be wise to get an air conditioning replacement rather than a repair.

Furthermore, you get full coverage of the warranty as well for the coming years ahead.

Air Conditioning Maintenance Tips

For the rest of us, we hope our air conditioner will continue to serve us well for the coming years.

In order to do so, you have to properly maintain and service your aircond just like you send your car to routine service every 6 months.

Maintaining your air conditioning unit is important to ensure it runs efficiently all year round.

You can follow the suggestions below to help you keep your unit running well:

  1. Cleaned the air conditioner filter at least once a month

Clean your air filter once a month, especially if you live in a city like KL where our air pollution index is high.

Plus, a dirty air filter won’t work as effectively at circulating air.

  1. Cleaned the coils at least once a year

Dust and grime can build up on the coils inside your air-con, reducing its efficiency.

Had it cleaned once a year by a professional to keep it running at maximum efficiency.

We understand there are a lot of DIY kits in the market. But can these really help in getting the job done?

It takes more than just spray and wash for sure.

  1. Check for refrigerant leaks

If your air conditioner doesn’t seem to be cooling your home as well as it should, check for refrigerant leaks though it can be other problems as well.

Not enough horsepower for a certain area might be the reason the cooling is not as expected as well.

For this kind of situation, use our aircond horsepower calculator to make sure of it.

Refrigerant leaks are a common problem with HVAC systems that are over 10 years old.

Over time, the seals in your system can deteriorate and allow refrigerants to leak out.


Maintaining a home air conditioning system is a time-consuming task.

If you have the luxury of time, you can do it yourself.

But if you are someone who is always on the move, then you should hire a service provider to look after your home aircond system for you.

Cheap air conditioning services might actually cost you more in the long run.

We had seen many fallen victims because of the attractive low price.

Aircond Service Ads

If the person doing the repair doesn’t know what they’re doing, your unit could end up becoming more damaged.

Would they come back for the second time if a problem arises?

Do you think an RM50 can cover all the mileage, labour cost, the ads they are running, consumables and etc?

Let alone coming back and help out for the second time without charges.

We are not undermining other aircond service vendors. We believe they are good at what they are providing.

What we are trying to say here is that aircond services or repair requires professionalism, skill sets, and most importantly trustworthiness.

A lot of the time, the cheaper the price is, the more money you’ll have to spend later on because of continued problems.

The price of an air conditioning maintenance service or repair should not cost an arm and a leg. A reasonable price should correlate with the quality of work.
