Determining Factors That Make the Final Cost Soaring?

A basic price quote usually refers to a typical job. Your actual quotation may differ greatly due to site-specific conditions:

• Number of indoor units: More fan coil units mean more piping, trunking, labour, and commissioning time.
• Brand and model: High-end brands like Daikin and Mitsubishi Electric usually have higher costs of aircons than lower-end, conventional models with inverters.
• Piping and trunking lengths: Standard lengths could be included, but running of pipework over longer distances, concealed pipework, or complicated layouts will result in higher costs.
• Property accessibility: The location of aircond shelf, availability of a suitable place for drilling, necessity of erection of scaffold, and rules and requirements from HDB or condominium association may influence the workload.

Some houses may require additional power points, upgrading of wiring, or even preparing electric installations before hand. If your home is still having old aircon unit, a contractor is likely to charge a fee when he dismantles the unit, collects it and disposes of it.

You may also get quotes for aircon installation if your existing equipment is old and you are thinking of getting a new system but don’t know how much to spend, or you need a second opinion before committing.

Ask the contractor who provides a written contract to clearly state what is included: copper piping length, insulation, trunking, brackets, number of electrical points, if the removal of an old aircon unit is part of the work, patching to fix holes, and commissioning of the new system.

This way, you will not end up with surprises after the work is done and, more notably, you won’t have to put up with a situation in the future where a part of or the whole system is no longer under warranty.

How to Get Aircon Installation?

Homeowners sometimes do not want new aircon units but would prefer to use their current ones and just need professional aircon installation services. These kinds of jobs are usually not expensive.

A single split unit with one indoor unit and one outdoor unit can be installed in about an hour of the worker’s time for S$450. Two-way fan-coil units with one outdoor unit might cost more than an hour’s time as there are more things to do. The worker will need about four hours time to do an aircon installation job for a three-ways system while a four-ways setup is likely to be a whole day’s work of the contractor.

The main differences between the two approaches are that a supply-only service leaves the buyer with a large number of decisions in terms choosing what he wants for the unit. In contrast, a supply-and-install option is much quicker and gives the buyer peace of mind when the whole system is under a warranty and there’s only one party the buyer needs to get in touch with.

A word of caution is that in some cases, the aircon unit supplier or seller will not be the one that does the installation job.

To avoid unpleasant surprises, you may want to get in touch with your supplier or contractor first and find out whether the installation is indeed part of what they deliver or not.

Better Deals?

Always make time to get two to three quotations. In fact, a third opinion is usually the cheapest one and it also helps you to be sure of a fair deal.

Compare different options to the best of your capacity so that you will find out what really costs the cheapest.

Do not just be tempted by a low price. Instead, you should evaluate whether it is a fair deal or not. A lower quotation will often come with either a limited warranty or no warranty at all or with a promise by which the work has to be completed in a certain duration only for a fee and if there is delay, the work is terminated, but the buyer will be compensated for the expenses made only to a certain extent, i.e., the money will be refunded if no harm is done to the goods or only for a specified period when the goods become damaged and so forth.

A lower quotation could also mean the work will be carried out by a less skilled contractor who will save time by not following proper steps that are required for installation of an aircond.

• Check the model numbers for both indoor and outdoor units. Double-check the BTU recommended capacity for each room.Check whether the mentioned costs include all required materials like standard piping, trunking, brackets, and electrical fixtures. Get the details of additional fees such as those of extra piping, core drilling, patching, and disposal of old unit.Separate out the workmanship warranties and the manufacturer warranties.Hospitalize the installer to explain the piping route and outdoor unit placement before they start work.

A properly detailed quotation ought to list these matters clearly. Especially HDB and condo installations are subject to access limitations and aircon ledge conditions that can really raise the final cost significantly.

A smaller system might be the option you are looking for in case you only want to cool off one room. In case the unit needs to cover two separate rooms, the medium size unit would be the one.
