What Does Mold in The HVAC Look Like?

Here are some pictures from an inspection that I did in Alexandria, Virginia this year. As you can see, it is pretty obvious when there is mold growing in your air handler. 

If you are suspicious about your indoor air quality, just taking off the cover to your furnace can be “enlightening”.

How To Install a UV Lamp On Your Duct?

Most UV light sanitizers will come with a paper template for the mounting procedure. It will be installed on your duct where your furnace or air handler is located (here is my detailed guide on installing HVAC UV lights).

I recommend following the size and placement of the holes on the mounting template for your UV light system.

You will first need to drill a pilot hole at the install spot, and then you will need to use a saw bit and drill in the hole.

The light bulb(s) will go through the hole in the sheet metal duct, and the UV light unit is secured to the ductwork with screws and possibly metal foil tape. Usually, the unit will just be plugged into a regular outlet in your utility room or closet but you also have the option of wiring the unit with your furnace (an electrician may be required for that).

How To Pick The Best UV Light For Your HVAC?

There are a few considerations to take into account when buying an KNOCK ultraviolet air sanitizer. There are generally two types of UV light bulbs, the long and short bulb.

If the unit you are buying has a longer bulb, it may be more difficult to install if your furnace is in a very small utility closet. However, with a longer bulb, there is more “surface area” so the light may shine along more areas increasing it’s effectiveness.

Another factor to consider is the equipment that comes with the purchase. Some UV light systems come with everything you need for the installation including the sheet metal drill bit that you will need to make holes in the ductwork. Almost all UV air sanitizers will come with a few screws to mount the system onto the duct.

Another thing to consider is the cord length. Most UV light systems come with a power cord that is 6′ to 8′ in length. If your utility closet doesn’t have a regular 3-pronged outlet, you may need to buy an extension cord that will go to the closest outlet.

And again, you can also wire the ultraviolet purifier into the air handler electrical system, and even wire it so it turns on only when the system is on. An electrician or contractor may be required for custom wiring.

How Are UV Light Sanitizers Different From Other Air Purifiers?

UV lights are different than furnace filters because they kill microbes while they are growing on the surfaces of the ductwork, the A/C coil, the drip pan, and other surfaces.

Furnace filters are a very important part of indoor air quality, and I recommend changing them monthly. However, I have seen many air handlers that had very good paper 3M filters, but on the inside there was extensive mold growth.

Indoor furnaces and air handling units are perfect breeding grounds for microorganisms like mold and viruses because they are dark, there is moisture, and a prevalent food source in the form of dust.

There are “point of use” indoor air purifiers, like the stand alone units you can place in your living room or bedroom. But these units will not affect the air quality of the whole home like how a UV light inside your HVAC can do.
