Where do you put UV light in HVAC?
The best location to install a UV light if in the A-shape is above, center, and downstream of the coil. This allows the A/C ultraviolet light to shine the most amount of light on the coil, while killing some of the airborne microbes. The second best location is below the evaporator coil (if there is room).
How much does it cost to install UV light in HVAC?
Coil UV lights have a light cost ranging between $60-$285, an installation cost ranging between $100-$225, a lamp cost between $10-$60 and an energy cost between $15-$30.
Should I install a UV light in HVAC?
Proper air filtration is the first line of defense against the circulation of microbes within your HVAC system. With the right conditions and proper installation, UV lights can be very effective at killing viruses, mold, and bacteria.
Can you install UV light in return duct?
Ultraviolet lamps can be easily added to an existing forced air system. Lamps can be installed either in the main supply or return duct of a central heating or air system. UV lamp systems can also be placed in the return air ductwork to clean the air as it passes through the system.
Where should a UV light be installed?
UV lights work best when placed around reflective surfaces and in conjunction with high-efficiency filters. To properly install the light, invest in UV-protected HVAC components in areas the light may affect.
Does UV light eliminate mold in HVAC?
UV lights in the air conditioning system will kill mold indirectly. It’s not biologically toxic, but it will eliminate the viability of mold spores, along with other organic compounds like bacteria, viruses and some volatile organic compounds (VOCs).
What does a UV light do for HVAC?
UV lights reduce the contaminants that build up in your ductwork, which causes your system to work harder. When you install UV lights in your HVAC system, they clear the buildup and improve airflow.
How effective are UV lights for AC?
According to the technician from Engineered Air, HVAC UV lights are very effective at controlling mold inside the air handler. All mold in line-of-sight of the UV bulb will be killed, keeping the coil mold-free.
How do I change the UV light in my AC unit?
How long does AC UV light last?
Generally speaking, a UV germicidal light that’s being used to disinfect your indoor air needs to be replaced every 9000 hours. This equates to approximately 12 months.
