UV Light for Air Conditioner

Inside of every air conditioner, you have the potential for a variety of problems. However, you may not realize that the biggest potential problem for your home could be the growth of mold within your air conditioning unit. It stems from dirty coils and ends by filling your home with mold spores. This can lead to a variety of health issues for your family including allergies and asthma. To avoid this potential risk, you should consider a UV light for air conditioner systems.

Why Install UV Lights in AC Units?

There are many reasons you may want to consider an ultraviolet light on your air conditioner. They are very effective at killing mold and mildew that may form on your air conditioner’s coils, the drain pan, and all the surfaces within the air handler. This can eliminate foul odors inside of your home and allow you to go longer between professional cleanings of your unit, especially if you also take additional steps to ensure your home stays mold free. These additional steps should include choosing high quality air filters, ensuring your home has less than 50% humidity, and take care of other routine maintenance tasks.

How UV Lights are Installed

A lot of the newest HVAC units have a UV light for air handler already installed. If you do not have a new unit, you will need to have one installed. However, the first step is to figure out which type of UV light you will need for your unit. There are some that use a single light and other systems use two. An AC repairman can tell you which is best for your unit and your home.

To install by yourself, you must cut into the ducts. Ideally, you will install it in your return air ducts that are solid enough to hold it, not in the soft ducts.. You should cut the hole just large enough to mount the UV light and use your hand to screw the mount on or you will risk stripping out the mount. You will also need to avoid touching the glass surface of the UV lamp. If you accidentally touch it, wipe it down to remove the fingerprints. Insert the bulb into the mount and lock it into place. Plug in the power cord to a grounded 110-volt AC wall outlet and never look toward the light. UV light is invisible, but it can damage your eyes. (Again, we recommend consulting a certified HVAC tech.)

Things to keep in mind when installing a UV light includes ensuring that flexible duct work is not exposed to the light because it can deteriorate the ducts. Therefore, you should place it 3ft from flexible ducts, purchase UV lights that have a metal shield so that it doesn’t shine toward the flexible ducts, install an elbow, or replace the ducts with a UV resistant duct. That is why many people choose to hire someone to ensure it is done right and avoid potentially expensive duct repairs later.

Will an Ultraviolet Light for AC Work on Your Unit?

A UV light that you install on ducts can be used on any air conditioning unit, but it is designed for newer HVAC systems. The UV lights for furnace or near the coils should be installed by a professional because you need get inside the unit. The only time that a UV light will not work is if you have an older unit that currently has other issues that will further increase the risk of mold formation.
