How and where to install a UV light in HVAC

Do you want to know how to install a sterilizing UV light within your HVAC system? You’re at the right place because even hospitals utilize UV-C light to sterilize operating rooms and medical equipment. To keep your air conditioning system free of mold and mildew and to safeguard the quality of your indoor air, we created this step-by-step guide on how to install a UV light.

How to install a UV light in HVAC – professional guide

As we all know, HVAC is an essential domestic appliance. We can keep all the rooms in our house at the perfect temperature all year round. In order to do this, we need to ensure that the HVAC is clean and free from any debris. We can do this by installing UV light in HVAC. if you want to install a UV Light in Atlanta, contact us.

1. Decide where to place the UV light.

Choosing the ideal placement on your furnace or air handler is the first step in installing a UV furnace light. The incorrect placement of the germicidal UV light will significantly impair its ability to stop the formation of mold or mildew.

The evaporator coil should typically receive the most light when installing the A/C UV light treatment system. This coil (and drip pan) are typically the source of HVAC pollutants, according to experts. The evaporator coil is also vulnerable to the growth of biofilms, which are microbial communities that stick together on a surface. An evaporator coil has a surface area of approximately 5,000 square feet.

The area of the air handler with the copper (or aluminum) tubing through which the refrigerant flows is known as the evaporator or A-coil. It typically resembles an “A” or tepee and frequently has the highest mold and dust accumulation. We should install the UV lamp so that it shines the brightest on the mold problem location, yet, if you have already had mold growth in your HVAC and there is a specific corner or area of the air handler that is prone to mold. If you already know that one area of your air conditioner is where mold grows the fastest, there is no purpose in testing with different spots.

2. Make the necessary holes for the UV light.

The indoor air handler must then have a hole (or two) drilled into it so the UV light bulb can pass through and illuminate the interior of the appliance. We have to place the primary component of any UV light sanitizing system on the outside of the product during installation. Only the long UV light bulbs enter the interior.

Before drilling holes, take measurements.

It is wise to take some measures after removing the furnace’s lid. Don’t drill a hole in the sheet metal just to discover that the UV light bulb won’t fit there. Additionally, you can carefully place the UV light bulb in the intended spot to get a sense of how well it will fit. Keep in mind not to touch the A/C UV light bulb. Your skin’s oils will weaken the bulb’s illumination and perhaps cause harm.

3. Attach the microbial UV light to the furnace.

Installing the UV lamp on the air handler is the next step. The UV product needs to have included a couple of screws for installation. To attach the UV light to the metal, just use a Phillips screwdriver or a cordless drill.

Be careful not to tighten the screws too much, since this could cause the UV light’s plastic to break. Don’t forget to wait until you have completely placed the UV light bulb before plugging it in. Your eyes and skin may be burned by the UV rays.

4. Ensure AC UV Light System Is Running.

You can now turn on the system after linking the UV light sanitizer to the furnace. The majority of new UV lights will have 5′–7′ long extension power cords. All you need is to plug the device into an existing socket. In most cases, utility rooms come equipped with an outlet.

Hardwiring the UV lamp into the furnace is an additional choice. You can even wire it so that the UV light only illuminates when the heater or air conditioner kicks on, preventing continuous operation. Simply turn the power switch on the device after plugging in the UV lamp, then check the sight glass to see if the UV light is indeed on. In the sight glass, there ought to be a bluish glow. Installing these UV air purifiers on the return duct side is an option. It reduces the likelihood that any important HVAC wiring or other plastic components may be harmed by UV rays.

5. Replace and disinfect the UV light bulb.

The average UV light bulb has a lifespan of one year. The presence of blue light does not necessarily indicate that the bulb has to be replaced. Humans cannot see the exact UV-C frequency that destroys mold. Although the device may still be emitting some blue light, there is not enough UV-C light frequency.

Additionally, it is advised to clean the UV light bulb after each season or every few months. You must remove the bulb from the device to clean it. Use a soft, lint-free fabric, such as a microfiber rag. Installing a UV light to eliminate mold and mildew in your indoor air handler shouldn’t be too difficult if you follow the instructions in this article. The fundamental concept is to drill a hole in the ideal spot, insert the lightbulb, fasten it with screws, and plug it in.

If you have everything you need, installing a UV light should only take 15 to 30 minutes. It can take more time, though, if you wish to hardwire the UV light into your furnace’s power. Other than that choice, the most difficult part of installing a UV lamp will probably be cutting the hole(s) with the hole saw.
