What are the benefits of installing a UV-light in your AC unit?

A better performing and cleaner AC unit: Bio-film, which is bacterial growth, and even mold tends to build up and grow on the various internal components. Not only do these mold spores and bacteria enter your home where they will make people and pets sick, but they also interfere with how your AC functions.

It puts more stress on the internal components, which results in higher energy usage, and these components are more likely to fail before their time. And because there will be no build-up and filth inside your system with a UV light installed, the components will keep functioning as they should.

Less cleaning: Because there is no bacterial or mold build-up in your HVAC and air vents, there will be less need to clean as it will stay cleaner for a lot longer.

Healthier indoor environment: Mold and bio-film build-up in ac units causes all sorts of airborne contaminants to enter your home. These create a range of health issues such as allergies, headaches, indoor mold infestations, the worsening of asthma problems, and in more severe cases, long term neurological issues. UV lights kill off the spores and bacteria that cause these health implications.

How does it work?

Coil sterilizers are the most common type of AC UV lights and is a single blue stick-shaped light that gets installed near the coils.

Its primary function is to protect the coils and other various AC components from mold and bacteria build-up, which is extremely beneficial because your ac unit will remain much cleaner for longer, which means less maintenance and better performance.

Any contaminants that enter the ac unit first passes by the UV light, which kills it first. It’s so effective that more and more hospitals are starting to use it.

It also means that a lot fewer germs and bacteria will make their way into your home. However, it must be noted that some bacteria and mold spores, although dead, will still make their way into your living space. Fortunately, germs and bacteria that do enter your home won’t be able to make you sick. The mold spores, on the other hand, although not able to colonize and spread, will still cause allergic reactions in susceptible people. An easy solution to this problem is use HEPA filtered air purifier and vacuum cleaners indoors.

Energy consumption

Energy consumption is surprisingly low, as most of these lights operate at a mere 25W or less. In case you’re wondering – if you leave the light running 24/7, it equates to around $2 per month. A small price to pay considering the money you will be saving on maintenance and repairs of your AC unit and not to mention a much healthier living environment.

Maintenance requirements

The only maintenance required for UV lights is that you change the bulb. However, don’t wait for the light to stop working before replacing it because the longer it burns, the less UV it puts out. To keep it functioning optimally, replace the bulb every 18 months.
