Aircon Servicing Cost

You cannot think that servicing aircon is all same. It is one of the major price confusion areas in Singapore. A general servicing is done in the range of $25 to $80 per unit, this consists of basic tasks such as clearing the air filter, draining the condensate, wiping the blower wheel, and checking that the refrigerant pressure is within the normal range. This is the minimum level of maintenance that is recommended every 3 to 4 months if you live in a humid climate like Singapore and the unit is just being opened or taken apart.

A chemical washing, which is also known as a chemical coil washing, costs about $80 to $180 per unit. It removes all the accumulated molds and grease from the coils and the blower by using a chemical solution. It is advisable to have it done once every year or so or even twice for that matter if you notice that your aircon is emitting a musty smell or there is a reduction in the blowing strength of the fan which could indicate there is mold on the coil or in the ductwork; a chemical washing will be the next level after regular servicing when general servicing alone is not sufficient to clean the system up.

The chemical overhaul is the most extensive and the most expensive type of servicing. On the scale of one to twenty-five, this method is the closest one to dismantling a whole unit and thoroughly cleaning each part of it; it can go all the way to the last part of the unit, including its components if the unit of aircon has any, and then reassemble it all the same way it was. In most homes, the only way that this is needed is once in two hundred years or after a long period of inactivity if the aircon is not being used and therefore being serviced.

A gas top-up costs approximately $60 to $180 depending on whether you are topping up with a new, a second-hand or a special type of gas. There is also a difference of price between R22 (which is an ozone layer-damaging type of refrigerant that is being phased out), R410A, which is the new type of refrigerant that will be used for the next few decades without harming the environment, or even R32, a type of refrigerant that is also eco-friendly, with the older types being the most costly ones.

Aircon Servicing Cost by Unit Type

You'll be amazed at the wide variety of aircon models and how different their servicing costs can be based on just the type you're using. Split AC units which are installed on the ceiling or wall and have an outdoor unit connected through the pipe are the ones mainly used by HDB and condominium dwellers since they're very convenient and easy to maintain. On both fronts, i.e. pricing-wise and servicing time-wise these are the cheapest units.

For home owners doing planning, servicing cost is usually a proportion of the number of units in your home.

For example, a 3-room HDB flat with 2 units would usually require a total cost of a full general servicing visit between S$50 - S$120. 4 or 5-room HDB flats with 3-4 units typically range from S$90 - S$240. Condos with 3-5 units would roughly cost S$90 - S$300 while 5-8 unit landed property could be priced from S$150 to S$480.

The unit price per service usually decreases as you add units. It is because the technician's time is mostly for the movement and setup rather than the actual servicing. Hence, people living in multi-unit apartments or contract customers tend to pay much less per unit compared to those who book regular single-unit visits.

One-Off Servicing vs Maintenance Contracts

If you regularly keep in the aircon condition, most likely the maintenance contract is your best bet. Servicing packages which are yearly or quarterly in Singapore are generally a big factor in your saving. They bring you a price cut of as high as up to 35% compared with the single servicing appointments.

However, that is not all. A contract is also a source of reminders to service your aircon periodically, so you get to have scheduled servicing even at busy days of the season. Also, a contract entitles you to booking before others at these times. Usually minor troubles of an aircon are also dealt at no extra fees by those who are the contracted people.

The cheapest way long-term, for householders with two or more aircons, is a quarterly contract that is the most effective one to stay in control of the cost of aircon servicing in Singapore in the future.

Factors That Influence Aircon Servicing Cost in Singapore

Pricing discrepancies can easily explain for why two "same" service offers have a great disparity. The first factor is unit condition & age, as units that have not been serviced for a longer time will require more servicing work leading to a higher cost for servicing such units. Accessibility is one of the other reasons, as units set up at very high places, in restricted areas, or ones to which you have to climb up via a ladder or scaffolding result in a more time-consuming and therefore more expensive servicing.

A different price can be offered for an aircon gas top-up depending on the type of refrigerant. For example, R32 will usually cost you less when the gas needs to be topped-up than the older systems of R410A or R22. Brand-specialist work requirement can also come out to raise the cost since some brands for instance Daikin, Mitsubishi Electric, and Panasonic necessitate exclusive tools or knowledge from the technicians. The cost also varies depending on the amount of units serviced per visit. It should be noted that more units on the service list means a cheaper charge per unit. Moreover, price differences could be due to the fact that in certain areas of Singapore travel time and therefore costs are quite different. This would affect the final quote in case these factors have been taken into consideration.

When to Service Your Aircon in Singapore?

With high indoor humidity level throughout the year and heavy usage of aircon, especially for most homes where it operates around 6-8 hr/day, the most common suggestion is to schedule your aircon general service every 3-4 months.

Neglecting regular servicing might boost your electrical bills by as much as 25% or 30%， shorten your unit lifespan and lead you to costly repairs. One example would be a blocked drainage issue that can even water damage to your floor if not dealt with early. You may well end up paying $500 to $2,000 if left unchecked

Dropping your aircon servicing to only a routine cleaning every 3 months or so is fine if everything seems to be functioning smoothly without the smell of mold and there is no moisture leak. It only becomes time to do the aircon chemical wash when there is the feeling of stale air, water dripping, etc., or when airflow seems to have decreased.

Tips on How to Not Be Overcharged on Aircon Servicing?

Aircon servicing cost in Singapore is relatively low, so being aware of red flags will make a big difference. One of them is getting a quote that is less than $25/unit as the technician is at least 15–20 minutes long and there is a high chance the work will be rushed up or there will be upselling of unnecessary services upon the technician’s arrival. It is best to make sure you get the details of each item and the amount in the quote from different service types only after the technician has finished working on all of the services in the scope. You also want to find out exactly what is in it - a filter cleaning is not the same as a full general service. Unjustified sur charges should be the last thing you should be paying for, so be sure to confirm the details on the transport charges, weekend surcharges, and the "emergency" gas top-ups before you agree to anything.

A screenshot or paper copy of the quote given before the job is the best way to avoid any "last minute" changes in the bill.
