Have you ever thought about the quality of the air circulating in your home?
You may not see it, but bacteria, mold, and other airborne contaminants could be making their way through your HVAC system. One effective way to combat these pollutants is by installing UV lights in your system.
But how exactly does UV light keep your AC and air clean? Let’s break it down.
What Is a UV Light for an HVAC System?
A UV light in an HVAC system is a special light installed in the air handler or ductwork that helps purify the air. As air circulates through your home, it passes through the UV light, which kills bacteria, mold, and viruses before they spread throughout your living space.
How Does a UV Light Work?
UV lights emit ultraviolet-C (UV-C) light, a shortwave light that has been used for decades in hospitals, water treatment facilities, and food processing plants to disinfect surfaces and kill harmful microorganisms. When airborne contaminants are exposed to UV-C light, their DNA structure is disrupted, preventing them from reproducing and effectively eliminating them from your air.
Where Are UV Lights Installed in an HVAC System?
There are two primary types of UV lights used in HVAC systems:
- Coil Sanitizing Lights – These are placed near the evaporator coil, where moisture often accumulates and creates a breeding ground for mold and bacteria.
- Air Sanitizing Lights – Installed in the ductwork, these lights purify the air before it is distributed throughout your home, reducing airborne allergens and pollutants.
How Effective Are UV Lights?
Studies show that UV lights are highly effective in reducing microbial growth in HVAC systems. In fact, research has found that UV lights can reduce mold and bacteria in a home’s air system by up to 97%. Hospitals, restaurants, and commercial buildings use UV technology to maintain cleaner air, and homeowners can benefit from the same technology.
The Benefits of UV Lights in Your HVAC System
Installing UV lights in your HVAC system can provide several key benefits:
- Improved Indoor Air Quality – UV lights help reduce allergens, bacteria, and mold spores.
- Better HVAC Efficiency – A cleaner system allows air to flow more freely, improving efficiency and reducing strain on your AC.
- Lower Energy Costs – An efficient HVAC system uses less energy, saving you money on utility bills.
- Odor Reduction – UV lights can eliminate unpleasant odors caused by mold and bacteria buildup.
Is a UV Light Right for Your Home?
If you or your family members suffer from allergies, asthma, or frequent respiratory issues, a UV light could be a game-changer for your indoor air quality. Even if you don’t experience these problems, installing UV lights can help keep your HVAC system cleaner and more efficient in the long run.
