UV Lights for HVAC Systems: Everything You Need to Know

Are you thinking of installing UV lights for HVAC systems in your residential, commercial, or industrial space? If so, you might want to stick around and read this post to make an informed decision.

UV lights for HVAC systems have been around for a long time. And they have shown 100% effectiveness in sterilizing harmful bacteria, viruses, fungi, mold, mildew, algae, and other unpleasant odors.

But do you think installing UV lights for HVAC systems in your space is the right decision? Let’s provide you with critical information about installing UV lights for HVAC systems to help you make an informed decision.

Types of UV Light Systems for HVAC

Air Sterilization:

In this system, the UV lights are installed in the return duct of the HVAC. Hence, the UV system will switch on only when your HVAC is switched on and running. This ensures the UV lights sterilize the air when pulled into the HVAC system. This also ensures the nearby region of the HVAC is also sterilized to reduce the chances of mold or mildew growth.

Coil Sterilization:

In this system, the UV lights are installed in the air handler of the HVAC system near the evaporator coil. Since the UV lights are always switched on irrespective of whether the HVAC is running, the coil is sterilized, preventing microbial growth.

Installation of UV Lights for HVAC Systems

You shouldn’t take a DIY approach to installing UV lights for HVAC systems. Instead, you should always call a professional for the job. Here’s what they will do.

1. The professional will install the UV light systems effectively to ensure there is no harmful exposure of UV to people around the premises.
2. If you choose air sterilization, the professional will wire UV light systems to the HVAC. This will ensure it is switched on as soon as you switch on the HVAC system.
3. If you choose coil sterilization, the professional will clean the air handler system before installing UV lights. This is done to clean the ducts and avoid any debris or dirt from getting stuck in the HVAC system.

Benefits of UV Lights for HVAC Systems

1. Reduce volatile organic compounds (VOCs), thus reducing any unpleasant odors.
2. Remove mildew or mold growth.
3. Sterilize any viruses or bacteria in the air.
4. Your AC will run more efficiently as the evaporator coil won’t have mold, mildew, or bacterial build-up.

Limitations of UV Lights for HVAC Systems

Needs Constant Contact with UV Light

Until now, you might have understood that to kill any bacteria and contaminants, it needs to make direct contact with UV light. This is possible only when all the air ducts of an HVAC system are clean and don’t have any leakage. However, if the air ducts in your HVAC are leaky, dirt and other debris will enter and mix with the air. These contaminants don’t pass through the UV light systems and hence aren’t sterilized.

Therefore, you must seal the ducts and leaks to get the most out of your UV light systems.

Can’t Remove Allergens

UV lights will sterilize the microorganism. However, it can’t remove allergens. So, if you have allergies due to dust, pollen, or other contaminants, it will still stay in the air and bother you.

Hence, if you are installing UV lights for HVAC systems, it would be wise to also install air purifiers to remove these contaminants from the air.

Bottom Line

UV lights for HVAC systems are a great way to ensure the air around the premises is always clean and breathable. Although it does have a few limitations, the long-term benefits outweigh these limitations easily.
