To sanitize HVAC, you need to follow some steps for perfect results. People are confused about this, and they want to know more about it. This article tells you about sanitizing HVAC, such as what is HVAC sanitization, how and why to do it, and other things that will clear all your confusion.

What is HVAC System Sanitizing?

Sanitizing the HVAC system is very important to remove all germs and bacteria. You need experienced technicians to sanitize it. The sanitizer is applied via a fogger, covering the whole interior of the HVAC system due to negative air pressure. This type of sanitizer has no smell and is entirely safe to use.

How to Sanitize HVAC Systems?

When Possible, Keep The Air Flowing

If the temperature control of the room is solely dependent on the HVAC system, you rely on recycled air. This means that germs when the bacteria enter your home but aren’t removed. One thing you must do is keep the air flowing.

Simple actions like opening windows or utilizing ventilation fans can aid in the removal of old air and the reduction of harmful air with bacteria in your home. If you allow natural air to flow in the room by keeping the window open, it will help sanitize the HVAC system.

Keep your windows open occasionally. This will also help improve the air quality of your room.

Control Humidity in Your Home by Installing Humidifiers

Virus & Flu thrive in low humidity environments. CNN recommends homes to be kept at 40-60%, as this keeps airborne and on surface flu germs on the low.

Here’s what you need to create the perfect balance -

a. Buy a hygrometer. This device lets you know the exact atmospheric humidity level of your house.
b. Purchase a whole-home humidifier that is right for your room size and efficient in germ prevention. Avoid entry-level humidifiers as they store their own germs and portable ones since they’re not always very efficient.

Apply Ultraviolet Light

Add UV technology to your HVAC system to sanitize it. This can be done by installing a directed UV-C light at the air mover that moves cooled or heated air throughout your home. You'll be sending air through powerful sanitizing technology as it flows around your home.

Check to see whether your humidifier has a UV-C light built-in. This can help prevent your humidifier from becoming a testing ground for the viruses you are trying to remove. By doing this, you can easily sanitize your HVAC system as UV light reduces the germs and bacteria from the air.

Purchase Air Filtration

We can’t always afford to keep our windows open - especially during the winter or summer. Recycled air is more prone to airborne germs. When dry air is recycled through your furnace time and time again, it is more likely to be filled with germs.

HVAC systems use filtration to remove dust and particulates from the duct, a. It cleans the air and returns it to the house. These filters can be thought of as air purifiers. After use, you have to replace these filters regularly. If the filters are not replaced, they will no longer be able to remove particles from the air. You will breathe in polluted air. The air quality will improve if the filters are replaced regularly.

Doctors recommend using a High-Efficiency Particulate Air (HEPA) filter, as they are considered the most effective air purifying tool available. These are efficient not only in removing microbes, but also dust, mites, pollen, and other allergens.
