Indoor air quality is an important piece of the home comfort puzzle. An HVAC UV light helps you stay healthy past sanitizing the air moving through your HVAC arrangement, reducing the mold and viruses distributed into your home'due south air.
What is an HVAC UV Light?
An ultraviolet (UV) lite emits powerful rays of energy that impale bacteria, fungi, and viruses. They are usually used in both home and commercial spaces.
UV lights may wait like futuristic lightsabers, but they've been used for almost a century. In the 1930s, hospitals used these lights to care for conditions similar tuberculosis.
At that place are 3 types of UV radiations: UVA, UVB, and UVC. When y'all put on sunscreen, you lot're blocking out UVA and UVB rays.
The 3rd diverseness, UVC, is used in HVAC lights and lasers. UVC rays have the highest energy of the three, and they are the only rays powerful enough to kill microscopic germs.
How do UV lights for HVAC work?
UV light for HVAC systems is installed either in your air handler or in your ductwork. When germs move through the central air system, they somewhen make it to the sanitizing light.
Once the germs are exposed to the light, they blot the light's UV rays. The UV rays disrupt the Deoxyribonucleic acid of the germ. When leaner or mold'southward DNA is damaged, information technology will either die or become unable to reproduce.
There are two varieties of UV sanitizer lights. Ringlet sanitizing lights sit near your evaporator curlicue. Air sanitizing lights are placed in your return vents, which are role of your ductwork.
HVAC UV light model types
Between the 2 models of UV calorie-free for HVAC, the "amend" choice depends on your organization and needs. Both piece of work effectively and can help promote cleaner air.
Still, they differ in ways that could impact your buying determination. Ringlet sanitizing lights are great at keeping your HVAC system clean, but air sanitizing lights do the best job of cleaning the air itself.
Note that you need a cardinal HVAC system to utilize either variety of light. If y'all don't have central HVAC, alternatives like air purifiers or air scrubbers are worth checking out.
Curl sanitizing lights
Scroll sanitizing lights look similar long, thin fluorescent lamps. They are the more than common and less expensive of the two varieties.
In an air conditioner or furnace organization, the air handler is the component inside your home. Inside the air handler is an evaporator coil.
The evaporator coil holds the liquid refrigerant that cools your domicile. Since the roll comes in frequent contact with the liquid refrigerant and the bacteria in the HVAC system, it'south a convenance ground for germs.
When the evaporator ringlet builds upwards too much moisture and bacteria, information technology can corrode. This makes the curlicue less effective, which means your dwelling isn't every bit comfortable as information technology could be. The leaner buildup can besides harm your HVAC system.
This model of UV low-cal is placed right above or next to the evaporator gyre. The light helps continue bacteria and fungi from forming around the gyre.
Coil sanitizing lights are normally kept on 24/7. You can buy them in unmarried or dual-lamp units.
We recommend coil sanitizing lights if you enjoy taking on DIY projects. Coil lights are less expensive and easier to install than air sanitizing lights.
If you're focused on keeping your HVAC system running smoothly, get for coil sanitizing lights. They can kill the germs and gunk sitting well-nigh your coil, helping you salvage on long-term repairs.
Even so, air sanitizing lights are more effective at cleaning the air. If yous accept severe allergies, scroll sanitizing lights may not be powerful enough to reduce your symptoms.
Air Sanitizing Lights
Air sanitizing lights are installed in the ductwork of your central HVAC system. They usually resemble coil sanitizing lights, merely some models are horseshoe-shaped.
Render vents suck in air from each room, so send it through the central HVAC arrangement. Air sanitizing lights alter the Deoxyribonucleic acid of the germs soon after they get sucked through the vent.
Depending on how the air sanitizing lights are installed, they could exist wired with your blower motor and will turn on and off in sync with your motor. These models are less popular than whorl sanitizing lights, in part because they're typically more expensive.
Air sanitizing lights treat indoor air quality problems better than roll sanitizing lights. Because air sanitizing lights clean air coming through the render vents, the air is sanitized every bit it enters your HVAC organisation.
If you have respiratory concerns, we recommend going with air sanitizing lights. With the higher cost tag comes better air cleaning abilities and greater peace of mind.
Does a UV light for Air conditioning actually piece of work?
Since viruses and bacteria are microscopic, you can't see a UV calorie-free at work. Though their cleaning power isn't visible to the man eye, multiple studies suggest that UV lights impale germs at high rates.
In 2015, Duke Medicine published a written report showing that UV lights killed 97% of antibiotic-resistant leaner, or superbugs, in hospitals.
Plus, UV lights have been shown to piece of work specifically for HVAC apply. A 2001 study from the American Society for Microbiology showed that whorl sanitizing lights drastically lowered the amount of living fungi in an function's HVAC system.
Air sanitizing lights take a better reputation for killing airborne germs. Still, fifty-fifty coil sanitizing lights have been proven to tackle contaminants effectively.
Benefits of UV light HVAC
A UV sanitizing calorie-free is a great mode to keep your family (and your HVAC organization) healthy.
UV lights target germs that can worsen weather condition like asthma and COPD. These lights can besides kill off volatile organic compounds (VOCs), which crusade odors like tobacco smoke.
Plus, both varieties of sanitizing lights go along gunk from edifice up and moving through your HVAC organization. This cleaning power can keep your system running better and longer.
With a more efficient unit of measurement, yous'll spend less money on repairs and maintenance. That's why UV sanitizing lights can be a helpful addition to whatsoever habitation with a central HVAC system.
Whether you want to maximize your HVAC system's efficiency or keep the furnishings of allergens abroad, a UV light is a smart long-term investment. This cleaning tool can aid your unit last longer and create a cleaner environment for your family unit.
UV light for HVAC cost
| Type of Light | Initial Equipment Toll | Installation Cost | Replacement Bulb Cost | Monthly Energy Price |
| Curl Sanitizing | $60-300 | $100-225 | $10-sixty | $15-thirty |
| Air Sanitizing | $80-400 | $150-295 | $15-125 | $15-30 |
Air sanitizing lights are the most expensive of the two models. Since they accept to exist installed in your ductwork, the installation is more invasive.
Replacement lamp bulbs are an ongoing price yous'll need to consider. Your UV light may have one or two lamps, and each bulb should be switched out every vi to 12 months.
Thankfully, there'southward no notable difference in energy costs between the two types of light. Neither should guzzle up energy or spike your monthly electric bill.
HVAC UV light installation
DIY aficionados, this one is for you lot: whorl sanitizing lights can be safely installed at home. Opting for at-dwelling installation can save hundreds of dollars, only it tin exist challenging.
One obstruction is that installation requires carving a hole into your air handler.
The hole must be the same size every bit the UV light, normally between i.v and 2.5 inches. An X-Acto knife tin can be a helpful tool for precise cutting.
The next step is to push button the UV lite through the hole you just made. Then, y'all screw the light into the air handler.
Finally, plug your lite into an outlet. The standard 120 Volt outlet is compatible with most UV sanitizing lights.
It's important to exist precise when cutting the hole. If yous'd rather not run the risk of dissentious your air handler, yous may want to go out the installation to an HVAC technician.
Unless you have lengthy HVAC feel, we don't recommend installing air sanitizing lights at habitation on your own. In that location'due south more room for error, and information technology tin can accept a lasting effect on your system's energy efficiency if it goes incorrect.
Similar to coil sanitizing lights, air sanitizing lights involve cutting a hole in your ductwork. If the hole is also large, it creates a leaky duct.
Leaky ducts are problematic obstacles to your home comfort. When air escapes through the holes, your unit compensates for the loss by running longer.
When your HVAC system has to work harder, it leads to higher electricity bills. The extra run times could besides wear down your unit, and it may need more frequent repairs.
Leaky ducts tin can also draw in germs from outside your HVAC system, like in your crawl space or attic. Poor installation can defeat the purpose of installing a UV light, so rent a pro if you have reservations almost how to complete the work.
Exercise I demand a UV light for my air conditioner?
