HVAC UV Lights to Kill Bacteria and Germs


Are you concerned with your home’s indoor air quality (IAQ)? Does your air quality seem to get worse in the autumn and winter? If you’re dealing with IAQ issues, Estes Heating & Air Conditioning suggests you install an HVAC UV light. This will help eradicate germs, bacteria, and other harmful particulates before they enter your home.


Of course, most people have heard of using UV lights to clean surfaces and air. But you probably want to know if UV lights actually work. In this newsletter, we’ll provide evidence supporting UV lights, show you the options available, and what their benefits are.


Science Supports the Use of HVAC UV Lights


UV lights have been used to kill off harmful particulates including mold, viruses and bacteria for more than 100 years. Hospitals, hotels, grocery stores and airlines use them to sterilize equipment and the air. Studies have shown that UV lights are highly effective in killing bacteria and other germs. In addition, this study supports using HVAC UV lights to kill off a variety of harmful particulates.


Who Benefits from HVAC UV Lights?


Everyone can benefit from HVAC UV lights. You should definitely consider installing them if you suffer from asthma, COPD, allergies or a compromised immune system.


2 Types of Residential HVAC UV Lights


Residential HVAC systems use one of two different kinds of UV lights: coil purifying lights or air purifying lights. Keep in mind, several different terms are used to refer to these lights: sanitizing, sterilizing, cleaning, etc. However, all HVAC UV lights fall into one of these two categories.


Air Purifying UV Lights


Purifying UV lights are designed to kill bacteria and also other particulates in the air. Sanitizing UV lights turn on when your HVAC kicks on and they are installed within your air ducts. These UV lights focus solely on cleaning the air as it passes through your system. They are effective at killing off bacteria and also germs before they can enter your home.


Coil Purifying UV Lights


Sterilizing Coil lights are, by far, the most popular choice for homeowners. Coil sanitizing UV lights are installed near your HVAC system’s indoor evaporator coil. They run continuously and are also designed to keep your HVAC’s coils free of bacteria and mold.


Other Benefits of UV Lights


UV lights can do more than just improve your home’s indoor air quality. HVAC UV lights can also improve your airflow, make your air fresher, increase your energy-efficiency, and lower your bills.
