Edit ArticleHow to Clean Split Air Conditioners These days almost every household needs some form of air conditioning, often the split ductless air conditioner. This system is so compact, so energy efficient, and so low cost that most new homes are now pre-installed with it. However, these devices are small, so cleaning them can be a daunting task. What's more, having them cleaning professionally can be ridiculously costly, costing as much annually as 25%~35% of the cost of a new system. Hence, here is a set of DIY instructions for anyone who wants to clean their air conditioning units and get back the strong cool airflow of a brand new air conditioner. Be sure to read the warnings at the bottom first to avoid electrocution, and in my opinion it is essential to remove the front cover and clean inside it to avoid mould reinfecting what you have cleaned! Buy an aircon wash bag. Buy a good coil cleaner. Avoid the foam type coil cleaners because they can be messy and spread foam everywhere.

Foam sprays also may not penetrate the coils or rotor fan blades properly. So stick to liquid solution sprays. Beware of buying harsh chemical cleaners that are designed to attack organics, as they may damage newer air conditioners. Newer split air conditioners often come with their cooling coils coated with a blue-colored hydrophilic layer (which keeps the condensation flowing over the coils easily to improve airflow strength). Install the aircon wash bag around the split a/c unit (called an FCU-Fan Coil Unit) on the wall.no power to air conditioning unit Start spraying the chemical solution over the coils.good portable ac units Spray the rotary blades hidden in the outlet of the airflow.what is a 4 ton ac unit Wait for 10 to 20 minutes for the cleaning solution to work.

Wipe down the fan coil unit. Be gentle and try not to exert too much pressure when brushing the cooling fins. They do bend and collapse easily under too much force. To avoid or clear a drainpipe clog, spray some coil cleaning solution into the drainpipe. Then flush water down the drainpipe. If you can reach the other end, use a wet shop vac to suck out and clear the drainpipe. This should be done especially if you have a leaking air conditioner. Use the long reach nozzle or a toothbrush to push the rotary blades round to get at all the blades. If you know how to remove the front casing of the air conditioner, you can clean the coils more thoroughly. If your sprayer is strong enough, the pressure alone will cause the blades to rotate, as long as you focus the spray on the lower third of the rotor facing you. Before you begin, you can remove the drain plug from the drip tray in your aircon unit to allow all the dirt to drain into the wash bag instead. This can avoid letting too much dirt flow into the drainpipe.

A used toothbrush can be very useful in dislodging and scrubbing some of the stubborn spots on the coils and everywhere else, especially areas near the airflow outlet. Avoid spraying any solution on the right side near the electronics. Lots of coil cleaners recommend leaving their chemical solution on the coils and letting the condensation clean and flush it away. However, rinsing it yourself is preferable, because the flushing action allows you to remove the tons of trapped dirt. Also, leaving cleaning chemicals on the coils gives rise to VOCs (Volatile Organic Chemicals), which are usually not healthy for our respiratory system even if they are organically natural products. Long term exposure to such concentrations of cleaning chemicals is not advisable. Turn off the mains power supply breakers that control the air conditioner unit, including the compressor, before you start this cleaning process.If your home is equipped with a central air conditioning system you may have noticed a drain line on the outside dripping water near the air conditioner.

This line drains condensation from the inside air handler to the outside. If this line clogs (usually from algae) it can cause water damage inside the house. You can prevent a clog by simply pouring a cup of household bleach into the line from the inside. To remove a clog once it has occurred, attach a wet/dry vacuum to the drain line outside (removing the paper filter first) and suck the clog out.

Although it needs prompt attention, sometimes it is only a very minor problem. In the cooling mode, the indoor evaporator coil and the suction line sweats. That's why it is wrapped in black insulation.

If the insulation is missing or has been torn or split, it can cause dripping. Obviously this is easy to repair. The evaporator produces a lot of water during the summer as it removes excess humidity from the air. The water runs down the outside of the coil into a pan that has a drain. The drain goes outside the house into a gutter or directly to the ground. If the coil is dirty, the water mixes with the dirt; the dirty water ends up in the pan, the drain trap or anywhere else it can cause a problem. As the water flows by gravity, it doesn't take much dirt to clog a drain and if your coil is located in the attic or finished room, serious damage can result. This is a very important reason for having clean filters and an annual inspection that includes coil cleaning. Sometimes the indoor coil actual ices up. When the ice melts, excessive water all over the floor or ceiling is the result. Indoor water problems are not just limited to summer. Some of today's high efficiency furnaces also produce condensation, which must be drained.
