Sometimes, for no apparent reason, an air conditioner smells bad when we turn it on. That bad smell may be due to poor installation, or some kind of external problem. To remove odors from the air conditioning we must resort to homemade products or tricks.
The most common problems with odor in an air conditioner are dirty filters, poor installation, dirty filters, an air freshener that ends up creating a bad smell or a strong odor source.
How to Remove Odors From Air Conditioning |Step By Step
A very common cause of odors in the air conditioning is dirty filters. We often forget to maintain the air conditioner at least once a year. Filter cleaning is a very important thing for our equipment to run smoothly. The air conditioner smells bad when we do not perform preventive maintenance and the filters are not cleaned. Particles that stay in the filters result in different bacteria appearing causing odours. In addition, the filters are saturated with dirt and the particles sneak into the air conditioning unit, depositing in the exchanger, drain tray and fan.
When dust particles have passed the filter and are in the inner exchanger, cleaning is much more expensive and difficult.
When installing an air conditioner, the most important point to avoid odors in the air conditioner is the installation of the drain, since the drain tray must have slope so that the water comes out and does not get stuck in the tray. Over time it will start to smell bad water stagnant in the tray.
Also, it is very important that the drain has a siphon, to prevent the smells of the drain from going up the pipe and when we turn on the air conditioning will spread it throughout the room.
A Good Smell Creates a Bad Smell
If your air conditioner is clean, with up-to-date maintenance, but still smelly, a good idea is to check if you’re using air fresheners, incense, sprinklers or any type of air freshener.
We should never use air fresheners as soon as we have an air conditioner on. At first, this type of odors smell very good, but when passing several times through the filters and inside the equipment the odor will be unbearable when the machine starts working and we will have to clean the AC ducts.
