How a UV Light Works?

Bacteria and germs usually develop in a dark or moist place. You will often see mold in your basement. The reason behind this is the place does not have access to sunlight. Sunlight has UV rays that prevent germs and bacteria from developing. That is why when something does not get UV rays, it is more prone to have molds.

UV ray is known to be germicidal, especially UV-C. This means this type of UV ray will kill microorganisms like germs and other bacteria. You will notice on a rainy day, when you leave your clothes to dry indoors, it starts to stink. This is because your clothes start developing bacteria which causes this unpleasant smell.

You will never face this problem when you dry your clothes under sunlight. The sunlight's UV rays will kill any microorganism in the cloth hence making your cloth smell fresh and clean. UV ray is the most effective germ killer. It is so effective that it is even used in medical facilities.

Most medical researchers experiment with microorganisms. They need to make sure that no other organism is reacting with their experiments, or else the result of their experiment will be flawed. That is why they use UV rays for sanitation.

The UV ray wave penetrates and reacts with the DNA of the organism. This reaction is so fatal for them that the DNA stops functioning, eventually causing the germ and bacteria to die.

What To Look For Before Buying?

With the market offering so many options, finding the best UV light for HVAC system can prove tricky. The following factors will help you narrow down your choices.

UV-C output power

The UV light you purchase should be powerful enough to eradicate the bacteria, fungus, mold, viruses and mildew in the air ducts. It should be able to remove all microbes from other rooms in the house.

Ozone free

This is an essential when it comes to preventing irreversible pollution while improving the aesthetics of your home. Ozone production also reduces the efficiency of air conditioning systems by corroding the surfaces. By purchasing an ozone free UV purifier you not only contribute towards carbon footprint reduction, but also improve the lifespan of your HVAC.

Ease of installation and cost

It is best to buy a UV light for AC that is easy to install and within your budget. Look for features like magnetic brackets and installation guides. The product should also comes with all of the accessories you’d need for the task like aluminum tape, screws and template.

Power consumption

UV purifiers come in different amounts of power depending on the manufacturer. This is attributed to the fact that manufacturers use varying technologies to make energy efficient products. Some use a titanium oxide reflector while others use zinc ions. Some UV lights for HVAC use 9 watt bulbs while others use 18 watt bulbs.

UV-C Wavelength

This helps identify the effect of light on microbes in the air. UV light has a wide spectrum of wavelengths, and this affects its effectiveness at getting rid of bacteria, viruses and organic particles that may cause odor development. Look for models with lower wavelengths as they’ll offer optimal performance.

Negative ions

The UV purifier system you choose should be able to produce hydroxyls as well as negative ions. These are crucial to cleaning and circulation of air in your home.

Easy bulb replacement

UV lamps don’t last forever and when they stop working, replacement is required. This should be easy to accomplish, preferably with a twist out twist in method. The replacement bulbs should be readily available on the market. Some manufacturers include extra bulbs to make things more convenient for you.

Where Can You Install UV Lights in Your HVAC Unit?

The most common noncommercial use for UV-ray light is for heating and cooling systems. Earlier, most people faced this problem that the air in their house smelled funny.

Some even complained, their cooling system wasn’t giving them the expected performance. Later they realized their system was filled with molds. Now, this was a very serious problem that had to be dealt with.

In your house, the cooling or heating system is very essential. And the whole atmosphere of your house will depend on your HVAC system. 

If your HVAC system is infested with bacteria and germs, then the air you are breathing in your house will have germs as well. You don't want your house to smell like mold or musky. Apart from the bad odor, it is also not hygienic.

Thankfully, if you install UV germicidal lights in your HVAC system, then you can easily get rid of this problem.

UV light is required in the part which does not have access to sunlight. So, the part which you use indoors, more specifically the cooling coils, needs UV light. In case you have a central AC, then you can install a UV light in the ductwork.

The places we mentioned are more prone to have bacteria or germ buildup. Therefore, it is the ideal place for installing UV light. The best UV air purifier for HVAC will prevent molds from developing, and the system will even last longer.

Mold usually disrupts the activities of the HVAC system, causing pressure on the system, and your system even uses more electricity.

HVAC UV Light Installation

Installing HVAC UV lights is easy if you know what to do. And while the method of installation may vary from one model to another, the rules are mostly similar.

Here’s a quick installation guide for you:

  • Start by cutting an opening larger than the base of the UV light in the duct.
  • Slide in the UV light housing and mark the holes for fixing the screws. You can use the template provided to mark the holes and drill them.
  • Pass the connecting lead before positioning UV light housing inside and insert the screws.
  • Fix the UV probes then close the opening the duct with a tin sheet before sealing with duct tape.
  • Connect the lights to standard electric outlets and switch on the system. Don’t forget to adjust the thermostat setting to auto.

What Size UV Light Do I Need for My HVAC System? 

The size of the UV light matters a lot.  This is because the size will determine the area it can cover and also the power of the UV rays it can produce.

Let us better understand this with an example. Imagine you recently moved into a new house and you need to get a light for the hall room. Now, the first thing you need to consider is the size of your hall room.

The light you buy for your hall room will entirely depend on the size of the hall room. If your hall room is big and you get a small light for it, the light will not be able to brighten up the room properly. It will look dark and gloomy.

Similarly, if the room is small and you get a big light, then the room will be too bright. Your eyes might start hurting due to the brightness. The concept is quite similar when buying a UV light.

Therefore, getting the proper size light is mandatory. In the case of UV light for the HVAC system, the size will depend on the size of your HVAC unit.

If it is a small unit, like a split AC or a medium-sized heater, then a medium-sized UV light will do the trick. However, if it is a big unit like central heating or cooling system, then it is best to get a big one.

The idea is that the light should cover the area where the mold will develop. So, first look into the area where mold will develop, then buy something which covers that area accordingly.
