UV Lights for HVAC Buying Guide

You should always make sure that you are considering whether or not you will get UV lights installed in your HVAC system. You need to decide if you want the air to be cleaned even more before it goes into the ducts or leaves, and these UV lights can help. They will get rid of all germs, bacteria, and more, so keep reading to find out a few of the top things to help you with buying the suitable model.

Can UV Lights Help My Air Quality?

If you are wondering if installing any UV lights would help air quality, you should know it will. These lights are often used for severe allergies since the allergens would be reduced with the lights’ usage. This is why hospitals and clinics utilize UV lights to keep the various medical surfaces disinfected and clean.

If you have these installed directly into the HVAC system, they will help clean the indoor air and the entire system. If you have one of these going, then all of the microbes in the air would be killed as they go through the system. The ducts can often contain allergens, bacteria, fungi, I, and mold, and the UV lights are a great way to avoid using chemicals to sterilize and kill the mold, organic growths, and bacteria.

How Do UV Lights Help?

The HVAC units can become contaminated with bacteria, allergens, viruses, dust, and much more, and if you use the UV lights, it will help. These lights will kill bacteria and allergens and mold that would build up in the system that you might not be able to see. These aren’t things that you can see with your naked eye, and the UV or ultraviolet systems will help prevent the build-up of everything on the surface of the ducts and coils of the HVAC system. These will also improve your system’s energy efficiency and airflow, which means you won’t have to clean the vents as often.

This will be important if you live in a humid area where mold can grow faster or even with severe health-related issues. Ensure that if you are thinking about what system you will use and what other additions you can get, the easier it will be. These will help with sterilizing and disinfecting any of the air that is going through your home.

Benefits of Installing UV Lights for HVAC Systems

Before you can make a final decision about if the UV or ultraviolet light is going to be suitable for your HVAC system, you need to know some of the top benefits. There are numerous benefits that one should be aware of to make an informed decision, such as:

  • Reduces allergies and illnesses – Many allergens and diseases can be spread through the air that goes into the HVAC system. However, if you use the UV lights in the right strength and placement, then most of these microorganisms that might be lurking can be killed. These can be found not only in the air ducts but the coils, and these might be hard to spot. However, if you have bad allergies or are often sick, this might be considered for your home.
  • GET rid of odors – There will occasionally be odors transported through the HVAC system, including burned food, paint, tobacco, or any other contaminants that might be in your home. This would go through the entire house, and these odors might not be just annoying, but they can be dangerous as well. However, if you have one of the UV light systems installed, they will help eliminate these compounds in the air so you can breathe easier with fresh air.
  • Better airflow – Also, the contaminants building up in the duct would be reduced by using the UV lights. This means that you will have more airflow throughout the system since the lights, once installed, can help with clearing up everything building up. If you have a better airflow, you can control the air coming into any room, and you can shut them entirely if needed.
  • Saves money – Another benefit you need to know about is that you will save money if the UV lights are cleaning up your system. This would be in the maintenance and repairs area, and you won’t have to worry about any issues with dust collection in the ducts. This would also mean spending less on energy and electrical bills because everything is running smoother.
  • Improved efficiency – The final benefit you need to be aware of is that your system would be much more efficient. This is because the system isn’t be clogged up like debris, pollutants, and dirt since it would be cleaned. This means that your system will deliver more air to the various rooms after the UV lights remove the build-up in the coiling coils, pipes, and ducts. Also, a more efficient system means that you will spend less on energy costs over time.

These are just some of the top benefits you will want to be aware of, so make sure you know what they are. If you know the various advantages, you can use them to help make your decision even more accessible when the time comes.

Types of UV Lights for Your Air System

You need to be aware of the various UV lights that you can use for your HVAC system. These include both the air and coil sterilization options, and you should know what they are. Here is what you need to know about these types of UV lights, including:

  • Coil sterilization – This type uses the stick-based lights that would be installed inside your return air duct. This would help sterilize the coil that handles the air, and the UV light would operate 24/7. This is the most popular type of light since it is also the most affordable option.
  • Air sterilization – This is a full UV unit for the lights installed to sterilize the air moving. This would be placed into the return air duct so that the air can be cycled along with the air handler blower system.

Ensure that you are aware of the various types to choose the one that will fit your requirements. You should know what the options are to make an informed decision.

Things to Consider When Buying a UV Lamp for HVAC

You also need to consider a wide variety of factors that would help you decide what UV lamp to purchase. Some of the top factors include:

  • Installation – You want to consider how easy it will be to install these lights and if you can do it yourself. Think about if the instructions will be clear or if you want to hire the experts to deal with this.
  • Power consumption – You also need to know how much energy the device will use to determine if it will save you money. This will help you decide which model will be more energy-efficient if you want.
  • UV light type – You need to think about what kind of light you are going for, the coil or the air. This would be determined by the budget you have and the usage you want to have, which could be in the return or access duct.
  • Bulb type – Another thing to think about is the type of bulb used, and you should find the best one. It would help if you also thought about how easy it would be to get a replacement bulb and how much it would cost you.
  • Ozone pollution – Also, ozone pollution is something you want to consider, especially if you’re going to avoid this. If you don’t mind, you want to find the bulb or system with the lowest levels, and some don’t have ozone used.
  • Extra features – You might need to look at many extra features, including an indicator for letting you know the bulb needs to be checked or replaced and much more. Think about what features you want, and then find the right system that would have those.

These are just some of the top features and factors you would need to choose when purchasing your UV light system.

How to Install a UV Light in an HVAC System

It would help if you also considered installing the UV light in your system. There are numerous steps that you should follow, including:

  1. First, choose the exact location where you would need to install the UV light.
  2. Drilling the holes that are required for the installation in the right location
  3. Screw the housing of the UV light to the furnace or the ducts and make sure you aren’t tightening the screws too much
  4. Plug the device in using the power device into any outlet nearby

There are easy steps to help you install the UV light, and you need to make sure to change your bulb every year or at least every 2 years. If you aren’t sure that you can handle this, then call the experts to get the help you need for installation.


  • Are these going to be safe for children?

These would be very safe to use around children since the actual light will not be anywhere near them. The light would be installed around the furnace or air conditioning, where the air would then go throughout the home.

  • How do I know when the light bulb would need to be changed?

Some models would have an indicator light to let you know when it should be changed. However, if there isn’t one, you want to change it at least once every year or even every 2 years to keep it operating the best.

  • Do the UV lights run all of the time?

This would depend on what type of UV light bulb you get and what you purchase. If you choose the UV lights put into the air handler, they will be all of the time. However, if they are placed in the ducts, they will only be required to be running while the AC is going.


You should always make sure that you are thinking about if a UV light system will work in your home. This would help remove and keep your HVAC system cleaner, which means it would last longer. Think about how much it will save you in maintenance and energy costs and which device would work the best for you when determining what to buy.
