Blocked Air Conditioning Drains – 3 Tips to Help You Fix It

Blocked Air Conditioning Drains

What is that one thing that you should ideally have installed in your home, which would ease off the intense heat and discomfort of the summer months? If you are thinking about an air conditioning unit as an answer, you are certainly on the right track. Air conditioners are one of the key additions that you need to have in your home, so that you can effectively maintain the perfect temperature in your rooms, during all seasons. An efficient air conditioning system can also cut down on excessive domestic power usage as well. Hence, it should be clear that, such a useful heating and cooling unit should be well-maintained, and properly repaired, as and when necessary. For example, if the air conditioning drains, and the pipes of that area get blocked, you need to set about getting rid of the problem immediately.


The drain passages of air conditioners (that are normally found just below the actual engine of the unit) form important components of the overall system. These pipes help to get rid of all condensed water vapor from the working unit of the AC, so that the latter can function smoothly and efficiently. However, these air conditioning drains might get obstructed due to several reasons. At such times, it becomes handy to be aware of the easy steps to remove these blockages, and make your air conditioner function normally again.


So how can the blockages that might form in the air conditioning drains be removed? In this discourse, we would be dealing with three useful steps of tackling with the problem. These ways can be listed as under:


i) Inspecting the drains of the air conditioner – Generally, soapy water can be used to check if the drains of your air conditioning unit are functioning optimally. If you have a central AC system, or a ducted one, you can pour soapy water on the drain tray (also known as the emergency tray) of the unit, after, of course, switching off the power of the latter. If the air conditioning drains are working as desired, the soapy water should run off along one end of the drains, and move down through the pipes of the unit. However, if the water tends to stagnate somewhat, and do not move away smoothly, that can serve as a confirmation that the drains of your AC has obstructions. If such is indeed the case, you have to take the necessary steps to clean these drain pipes of the unit,


ii) Source of blockages in the air conditioning drains – Next, you need to find out what is causing the obstructions in the drains of your air conditioner. Many common pests, like spiders, can easily be the reason behind the problem. Dust particles, dirt or twigs can also block the air conditioning system. A strap, that is highly flexible, can be pushed up and down along the drains of your AC, so that the obstructions can be removed. You can also pass compressed air (from the roof area) through the air conditioner to clean the drains of the latter, and


iii) Using Bleach Solutions – From time to time, you should also pour a special mixture, made out of water and bleaching chemicals, through the air conditioning drains. That would effectively destroy all forms of molds and other growths that can form in these drain pipes, thereby blocking them.


The cost of removing obstructions from the drains of your air conditioning system generally varies according to the type of the unit that is to be repaired. For example, fixing the problems with a central air conditioner that runs on electric power, can cost any amount between $1500 to $ 3000. On the other hand, if you are looking to repair your gas-run central air conditioner, you need to spend something in the range of $ 2600-$ 3500.


Air conditioners are exceedingly useful modern domestic appliances. They can maintain the correct and comfortable balance of room temperatures, and can help to reduce your costs of cooling as well. For optimal performance of these units, you should also make sure that there are no factors that are adversely affected the performance of your AC. In particular, if there are blockages in your air conditioning drains, you need to take the afore-mentioned steps to remove the obstructions, quickly and easily.
