Using a bigger size drainage pipe with insulation and inclined at the proper gradient will provide a smoother flow of water. This will reduce frequent clogging that will increase the risks of leakages and condensation which may damage your furnishings and flooring.


Different grades of wires are used in air-conditioning installation. Good quality wiring that conforms to safety standards is vital for safety. The consequences of using sub-standard or under-sized wires could result in potential electrical short circuits or even fire hazards.


Thermal insulation in air conditioning system is primarily used to reduce heat gain and heat loss from piping. Inferior quality insulation will result in higher condensation rate (due to humidity) which causes leakages and energy losses, resulting in higher electricity bills and more costly repairs in long run. Upgrade to thicker insulation (e.g 3/4 inch insulation) is available.


The way brackets are welded will affect its quality and durability. Brackets should be welded by qualified welders, tailored to sizes and installed by BCA-certified installers. Low-grade brackets may rust or snap off prematurely, such brackets that do not meet the government regulation pose risk which are classified as illegal installation and carry severe penalties.


The thickness and quality of copper pipes utilized for installation affects its lifespan. The thicker copper pipe SWG 21 (0.81mm) used is generally able to withstand a higher operating gas pressure (R410A/R32). Inferior copper pipes cannot withstand high gas pressure and may result in gas leakages, leading to premature failure of your air-conditioner and high replacement cost.


Gain City ensures that your air-conditioning perform at the optimum level with vacuuming to remove unwanted air and moisture from the refrigerant system before commissioning. If air remain in the air-conditioner and refrigerant piping, it will affect the compressor performance, reduce the cooling capacity, clogged the cycle of refrigerant and could lead to malfunction.

Are you paying more or less? Or are you paying for an installation that is not durable?
Solve your problems with our useful tips:

  • As reported in “The Straits Times”, close to 40% of air conditioner problems can be attributed to haphazard and shabby installations. These often lead to rusting, malfunctioning, water clogging, gas leaking and other undesirable consequences, resulting in unnecessary monetary loss and time wastage.
  • When an air conditioner is professionally and securely installed, it should last for several years. Inferior rubber insulation tubes, copper pipes, wires and brackets can have adverse effects on the performance of your air conditioner. Do compare and question the installation materials used by your air conditioner retailer based on our guidelines.
  • At Gain City, we take pride in our installation services and we do not compromise on the materials used. All installations carried out by Gain City’s BCA-certified technicians adhere to the highest standards in accordance to government regulations.
