UV rays happen to be one of the most effective disinfectants known to mankind. Today, artificial UV lights are being used in hospitals, salons, the hospitality industry, etc., to sterilize equipment and other materials. In a bid to make the air in homes and other indoor public spaces cleaner, UV light is now being used in conjunction with the indoor heating and cooling system. The aim is to improve the indoor air quality by eliminating the germs, bacteria, and viruses present in it.
What Are UV Lights?
UV lights or the ultraviolet lights are a form of electromagnetic radiation. It comes naturally from the Sun through the sunlight, and artificially through manmade UV lights. Artificial UV lights are used in tanning booths, germicidal lamps, curing lamps, etc.
More About UV Lights
UV lights have been successfully used in the treatment of TB or tuberculosis. In 1903, Niels Fensen even won the coveted Nobel Prize for this discovery. Since then, there is no looking back. In 1908, France used UV lights to sanitize the municipal water supply. Nowadays, it is even used in labs and meat processing plants for decontamination purposes.
Uses Of UV Lights
Due to its purifying qualities, UV lights are being used in various places. Its most common uses are:
1. Drying and curing of materials like inks and coatings.
2. Disinfection or decontamination for bacteria, viruses, fungi, mold, etc.
3. Sterilization and controlling the infection.
4. Inspections that require fluorescence.
5. Artificial tanning booths.
Advantage Of Using UV Lights
Most allergens, germs, and illness-causing micro-organisms are not visible to the naked eye. But that does not mean that they are not there. They are present in the air and on different surfaces. The prime advantage of using UV lights is that it sanitizes the surfaces and the air that comes in its path. Medical centers and hospitals have long been relying on this method to disinfect their equipment.
How UV Lights Enhance Indoor Air Quality?
UV lights can improve indoor air quality dramatically. They are usually placed in the form of a bulb directly inside the air handler, facing the evaporator coil (Coil Sanitizing Lights), or in the duct (Air Sanitizing Lights). Thankfully these can be installed in most modern HVAC units without any problem. When the bulb is on, the air that passes through its path gets disinfected. It is this treated and disinfected air that finally enters your home.
When the UV lights work cohesively with quality air filters, they ensure that pollutants or contaminants in any form do not enter your breathing space. This way, the indoor air quality improves, and your environment becomes cleaner and healthier.
Cost Of UV Lights For HVAC Systems
There are two types of UV lights that can be used in HVAC systems, and each of them costs different. However, when you are trying to work out its cost-effectiveness, you should also take into account the lamp cost and its cost of installation. To give you a basic idea, here is a small break-up:
1. Coil Sanitizing Lights – The coil sanitizing lights can cost anywhere between $60 to over $300. The lamp would cost around $10 to $60, and the installation cost would hover around $100 to $225.
2. Air Sanitizing Lights – The air sanitizing lights range between $80 to over $400. Its lamp costs between $15 to $125. And finally, its cost of installation varies between $150 to $300.
The energy cost for each comes to around $15 to $30 per year. Residential HVAC systems usually use one lamp, while industrial systems may use two. The life of the UV lamp can be anywhere between 9 months to 14 months.
How Long Do UV Lights Last?
Most UV lights have an estimated life of 9000 hours or just a little over a year. When the heating and cooling system is switched on, the UV light is switched on. It remains working until the HVAC unit is shut down. In most American homes, the central heating and cooling system work non-stop, so the UV light, too, works until it runs out and needs to be replaced.
When Is The Best Time To Replace UV Light?
The best time to replace the UV light is during the course of the annual maintenance of the HVAC unit. This way, you will never forget that it is time to replace it with a new one.
Is DIY Installation Of UV Lights Possible?
Some UV Lights are simple to install. They have a magnetic bracket that makes for easy and quick installation. These don’t need to be hardwired. If you have average DIY skills, you can install the UV lights that use magnetic brackets. The others that need hardwiring are a job best left to the trained HVAC technicians.
Are UV Lights Worth The Cost?
After reading all this, the burning question in your mind must be whether the UV lights are actually worth the expense? Well, all we can say is that if your health and that of your family is important to you, then yes, the UV lights are worth every penny spent.
The UV lights installed in the HVAC system can be thought of as air purifiers. They effectively kill the germs and other micro-organisms present in the air, including viruses and bacteria. They also help get rid of mold and mold spores. All in all, the UV lights for HVAC systems make for enhanced indoor air quality. The cleaner the air in your breathing space, the healthier you will be.
