Factors that affect aircon servicing costs

These are the typical factors that affect your aircon costs, namely:

  • The number of units: The more aircon units serviced, the more time will be taken (and more work, of course!) and the more costly it will be.
  • Type of servicing work: the more work and in-depth services (such as chemical wash), the more expensive it will be.
  • Type of aircon: The more powerful the aircon, the more costly it will be to service. Aircon servicing usually goes by the number of coils, hence it may affect your cost.
  • Odd hours: Should the servicing be an emergency and require an urgent service, aircon contractors will usually charge you extra for that.

Benefits of aircon servicing

The benefits of regular aircon servicing are numerous, which includes:

  • Water leaking rectification (by vacuuming) during the contract period
  • Minimise aircon system breakdown
  • Preventive measures against possible wear and tear, as well as subsequent problems
  • Cost savings, such as waiver of transportation charges throughout the contract period
  • Cost savings, in terms of aircon efficiency and durability
  • Saving on total maintenance cost (for chemical overhaul)
  • Healthier, cleaner air quality
  • Improve cooling efficiency
  • Entitlement to discount for ad-hoc repair work (for some companies)

All of these eventually lead to the most crucial benefit: prolonging the air-conditioners lifespans and ultimately saving you more money. 

According to HDB, you must maintain the outer wall face free from stains at your own expense and have an obligation to perform regular maintenance on your aircon to avoid inconvenience or nuisance to your neighbours.

If you do not attend to the nuisance, HDB will ask you to stop using or to remove the aircon.

Aircon Chemical Wash Price

When it comes to stubborn clogs or areas which traditional aircon servicing cannot reach, professionals may use a chemical wash as part of the solution to help solve the issue.

It is generally recommended to have your air-conditioning system chemical-washed once a year, both as a preventive measure and a solution to remove those hard-to-remove sediments stuck in your system.

Along with it also comes the health benefits, as a cleaner system can pump out cleaner air and maintain high efficiency. The rates of chemical wash in Singapore are:

Factors affecting aircon installation costs

There are several factors that affect the aircon installation pricing. They are:

  • Type of air-conditioner: Prices vary between the different types, such as split type, window type. For example, you can shop aircon via different categories, such as:
    • Aircon systems: There are different kinds of systems available, such as system 1,2,3,4,5,6. What is means is how many aircon units are connected to a compressor. If you need five air-conditioning units at home and a compressor to make them work, choose a system 5.
    • Energy savings: How cost- or energy-efficient the air-conditioning systems are
    • Categories: commercial, inverter, window and casements or portable ones.
  • Labour cost: per unit basis. Labour will most likely incur the most expenses when you are embarking on either an aircon installation or aircon repair project. A few factors which may be involved with labour pricing include:
    • Size of aircon units (capacity or more commonly measured in British Thermal Unit (BTU)). A typical master bedroom in Singapore can be sufficiently cooled by an aircon working at 9,000 BTU per hour.
    • Placement of aircon units
    • Parts (vents, ducts etc.)
    • Installation
  • Ductwork and wiring needed: The whole project needs to be taken into account. Work is required in order to check the ductwork and wiring, and extra work is needed for additional wires or replacement.
  • Number of Units installed: Of course, the more the number of air-conditioners to be installed, the higher the cost. While the units here are the indoor aircon themselves, it is essential to know that indoor unit usually refers to the physical units themselves (ones we see inside), while outdoor unit refers to the compressor that is usually outside of the home.
  • Complexity and expertise: For some projects, it can be complicated, and specific knowledge is needed. Be prepared to pay for more in such cases.

This applies for both central, split-system and room air-conditioner installation projects.

There can be 101 problems which may occur if you do the installation or repair yourself. Improperly designed systems may have ducts too small for air blowing out, and at the other end of the spectrum, an overly large duct may siphon off air that should be going to another part of the house.

In another case, the air-conditioning system could be undersized too large as well, providing more or less pressure than ducts are designed to handle.
