UV Light for Air Conditioning Systems

When considering upgrading a home air conditioning system, many factors come into play such as comfort, efficiency, cost, and warranty. But, how many homeowners think about the air quality inside of their home when making such a purchase?

There are a few ways to achieve the best air quality in your home like high-grade filters, but ultra-violet light for air conditioners is an addition that every homeowner should consider.

What is Ultra Violet Light?

UV Light was originally invented for the treatment of tuberculosis back in 1903 by Niels Finsen. He even won the Nobel Prize in Medicine for his groundbreaking discovery. UV light is a highly effective sterilization tool, and its use is widespread throughout the world. UV lights are used in disinfecting surfaces for bacteria and viruses, hygiene and infection control, and germicidal UV light applications can even be used for systems that need sterilization of water, air, and surfaces.

Why Should Homeowners Consider UV light technology?

Germicidal UV lamps are often used in HVAC systems to treat the air and sterilize any harmful pollutants and contaminants in the air. This is especially helpful for asthma sufferers and people with respiratory problems.

Mold, mildew, and bacteria growth are also common in HVAC systems and over the years, this type of growth can build up and enter the air you and your family breathe. Because HVAC systems are removing moisture from the air, the components can become damp themselves, providing the ideal space for growth.

Does UV Light Technology Really Work?

Yes, it does. UV light technology for air conditioners has been scientifically tested and proven to reduce fungal contamination inside of air handler units and reduce airborne pathogens. However, it is important that the UV light is installed properly, or it will not be as effective and a waste of money.

How Many Types of UV Lights For Air Conditioners Are There?

There are two basic types of UV light systems for an HVAC system. Homeowners can choose an air sterilizer or an air handler coil sterilizer.

The UV light for air sterilization cleans the air as it moves through the air conditioning system. This type of UV light is installed in the air return and turns on when the fan begins running, and it turns off once the system is shut down.

Air handler coil UV light sterilizers are installed near the coil. This type of UV light runs at all times and prevents bacteria and mold from developing on and near the coil.

Both UV light systems are beneficial in their own way, and homeowners can also choose to install both types to ensure all air and components of the HVAC system are free from harmful bacteria, growth, and pathogens in the air.

Are UV Lights the Only Way to Ensure Indoor Air Quality?

No. There are many ways in which homeowners can improve the air quality inside of their home. UV lights are effective for killing mold and dangerous bacteria, but homeowners can also perform the following to safeguard their family:

  • Make sure to clean air ducts and check to see that they are sealed and air tight
  • Install high MERV rated filters, but check to make sure the air conditioning system is designed for these filters
  • Perform regular maintenance, change filters monthly and clean the coil each year
  • Clean air ducts after any environmental hazard, or every 5-7 years

Do UV Lights For Air Conditioners Require Maintenance?

Once properly installed, UV lights do not need regular maintenance. However, during annual or preseason maintenance tune-ups, ensure that your HVAC professional is aware that the system has a UV light installed. A specialist will be able to change the UV bulb and ensure it is working how it should.

Can Homeowners Install UV Lights Themselves?

If a homeowner is mechanically inclined, they can likely install a UV light system. However, if the UV light is not placed correctly, or the right UV light is not used, it will be ineffective. It is important to hire an HVAC specialist to install any UV light systems. They will check to ensure the right UV light and placement is correct for the light application, gauge surrounding temperatures and humidity levels, as well as the reflectiveness around the UV light. All of these factors need to be addressed for the UV light to work as it should.

Is UV Light Safe?

Yes. Although UV light is a type of radiation, it is completely safe in the application for sterilizing air and surfaces. However, homeowners should never look directly into the light once it is activated. UV light can damage eyes, just like staring at the sun.

UV Light For Air Conditioner Cost

UV lights for air conditioners are not cheap, but once installed, there is little maintenance throughout the year. Depending on what type of air conditioner a home has, and what their overall goal is, a UV light system can cost anywhere from $500-1,500. If homeowners want to install both an air sterilizer and a coil sterilizer, the cost may be a little more.

Very Satisfied. Michael is always on time, Michael has been doing all of the plumbing related to our remodel. He always does exactly what he commits to do within the estimated cost. He keeps me informed if any wrinkles pop up, and his plumbing skills are excellent as we have had no problems or issues arise after he has left. Very professional! Highly recommend.

What Rick M says about us

We had other companies come out for estimates on what was considered a major job with jackhammers and replacing cast iron pipes under the house… having been stung before, we wanted another estimate just to make sure we were making an informed decision. The prior estimates went up to $21,000!
Bill Howe sent us an amazing veteran plumber, Dashawn and his co- worker Anthony. Dashawn did a thorough check of the problem, explained what he thought was needed … he did a final check and we were able to see for ourselves what was the problem. He recommended a complete cleaning to de-scale the pipes, and not the major work we dreaded. Thanks to his solid analysis and patience in making sure we saw what he saw, the issue was resolved completely, and saved us thousands of unnecessary work. None of the other estimates included the cleaning; only the major repairs. Thanks to Dashawn’s knowledge, professionalism and honesty, we’re Bill Howe customers.

What Carolyn Housman says about us

This was our second excellent experience with Bill Howe. We had a blocked kitchen sink drain 8/5. I was able to get a same day appointment which is AMAZING. Person on phone was very courteous and set me up right away. Tony arrived at the house (called me 30 minutes out so I was able to be ready). He diagnosed the issue (blocked drain, not the garbage compactor) and was able to snake it and ran the water for 10 minutes to be sure the drains were clear. He cleaned up everything and you would not have known he was even there. Thank-you Tony and Bill Howe, you always know how.

What Ed Gohlich says about us

Cory was our technician on this job. We had a time sensitive repair issue and Bill Howe understood and assisted with getting the job done quickly.
Cory was on time to start the job and finished it quickly. Upon his leaving our home he’s was courteous, very knowledgeable, explaining what the problem was and how he fixed it. Very good communication and this is the way it’s has always been when we use Bill Howe plumbing.
Great company to work with.
Thanks Cory.

What Bridgett says about us

I am extremely happy with the service we received from Bill Howe Plumbing. We were given an incorrect diagnosis of our main sewer line from another vendor, but Bill Howe’s servicemen came out for a second opinion, correctly diagnosed our problem and resolved our back up issues. We will continue to use Bill Howe for all our future plumbing needs!

Thank you Bill Howe Plumbing.
