Over time, dust and debris start to accumulate in your air conditioner. As air conditioner is usually out of sight, many homeowners forget to clean it. As a result, indoor air quality starts to deteriorate. But it’s important to understand that if you neglect air conditioner cleaning, it can affect your health.

Next time before complaining about a sore throat or watery eyes, check whether your air conditioner is clean or not. In this article, I’ll talk about the air conditioner’s irritants and ways to clean them.


Irritants in Your Air Conditioner & How to Clean Them

Viruses & Bacteria

Viruses and bacteria are known as pathogens. If pathogens build up in your air conditioner ducts and spread in your building, it can cause the sick building syndrome.

Due to sick building syndrome, all the people in your building will start to feel sick. But as soon as they leave the building, they will feel better. Also, due to the sick building syndrome, all your office employees will start to lose their productivity and become demotivated.

The sick building syndrome is common for those buildings that have a central air conditioner unit. That’s why if your building has a central air conditioner, you’ll have to clean your air conditioner air ducts regularly.

Again, as thousands of people are getting infected by the COVID-19, you’ll have to be careful more than ever. To keep your building safe from pathogens and especially COVID-19, you’ll have to clean and replace your air conditioner air filter regularly. Besides, don’t forget to clean the coils of your air conditioner.

The best way to prevent pathogens is to do regular HVAC maintenance checkups and cleaning. With regular HVAC maintenance checkups and cleaning, your air conditioner will function properly and safe from pathogens.

As the winter is coming, you’ll have to be careful about your building’s humidity as well. Generally, during winter, humidity level drops down drastically. But low humidity level is the breeding ground for pathogens. That’s why it’s recommended that you invest in a humidifier.

A humidifier will monitor your building’s humidity level and add moisture accordingly. As a result, your building’s humidity level will remain the same throughout the winter.


Pollution is a massive problem for big cities. If you live in a big city, you’ll have to make your HVAC design according to your building and surroundings. HVAC designs that work in rural areas may not work in urban areas. That’s why, for proper HVAC design, you should contact an HVAC design professional.

There are various types of pollution – dust, debris, smog, etc. Many think that the outside pollution won’t hamper the indoor air quality. But this isn’t true. If you don’t do regular HVAC cleaning, pollutants will start to enter your space and make your indoor air quality terrible.

Again, if your building has a poor ventilation system, it can make the air stagnant. As a result, all the pollution will move through your building and make the indoor air quality poor. If you notice a bad smell in your building continuously, there is a big chance that your building has a flawed ventilation system.

To get rid of this type of problem, you’ll have to plan your HVAC design according to your building and execute it properly. In your HVAC design, always put emphasis on your building’s ventilation system.

Dust Mites & Pet Dander

Dust mites and pet dander are one of the leading sources of air conditioner irritants. If you have an allergy to pets, you know that the animals won’t have to be present in the same room as yours. Pet dander is small and can travel from one place to another easily.

Again, dust mites are microscopic insects that grow exponentially in warm and moist areas. But unfortunately, there are numerous spots in the air conditioner that can be the breeding ground for dust mites.

To get rid of dust mites and pet dander, you’ll have to clean your air conditioner regularly. Apart from cleaning, you’ll have to replace your air conditioner air filter regularly. Also, you’ll have to clean your air conditioner air ducts once a year.

The best way to solve all these problems is by doing regular HVAC maintenance checkup and cleaning. By doing regular air conditioner maintenance checkups, your air ducts will be free from dust and mites, and you’ll have clean air.
