What Are the Benefits of HVAC UV Lights?

What are the main benefits of incorporating a UV light system in your HVAC setup? Truth be told there’s a lot to gain, such as…

      • Improved Indoor Air Quality: UV lights help in eliminating the presence of mold, bacteria, viruses, and more by breaking down the bonds that help them grow.
      • Healthier Home: Those prone to allergies, asthma, general illness, and respiratory struggles have the most to gain from improved indoor air quality – it makes a huge difference.
      • Heightened Efficiency: The more pollutants your heating and cooling system has to fight off, the harder it has to work – which means better air quality means better system performance.
      • Lower Energy Costs: A system that doesn’t work as hard won’t need to work as long either, resulting in lower energy bills month to month.
      • Increased System Lifespan: Premature breakdowns are much more likely to occur in systems that have to work harder and longer to fight off dirty air. Save yourself from making this huge investment earlier than you need to by working with us.

Keep in mind, though, that while UV lights for HVAC systems help prevent germs and their buddies from spreading, they don’t actually eliminate them. Because of this, they’re most helpful when paired with an air filtration system – something we’d be happy to set you up with.

How Does Ultraviolet Light Purification Work?

UV light technology works by breaking down the molecular bonds of the germs and bacteria that pollute our air. By doing so, it prevents them from growing and spreading throughout the air you’re breathing in on a daily basis. Here’s a brief breakdown:

The air flows through your HVAC system, passing the UV-C lamp that is included in your UV light purification system.

As bacteria, viruses, and other harmful particles pass near the lamp, the light disrupts their chemical makeup, which then makes it impossible for them to reproduce.

Since they can’t reproduce, your other HVAC air filtration products can effectively eliminate them without the threat of more forming.

Your HVAC system runs safer and more efficiently, while keeping your home better protected, year after year.

What’s the Difference Between UV Lights & Air Filtration Systems?

When it comes to indoor air quality, there are a lot of different systems and products that can work to keep your air cleaner and home safer. Because of this, people often get the various products and services confused with each other.

For instance, which one prevents mold? Which kills bacteria? Do they both do this? Does one kill the microorganisms, while the other does something else? We get it. There’s lots of information out there, so knowing what equipment would best suit your unique needs and household goals can be a struggle.

Here’s a rundown between these two commonly confused setups.

UV Light Systems

  • Stop the growth and reproduction of bacteria and viruses
  • Stop the growth and reproduction of mold spores
  • Assist air filtration system in relieving symptoms of allergies and asthma
  • Do not remove particulate matter (think dust, pollen, pet dander, etc.)

Air Filtration Systems

  • Trap and remove particulate matter (dust, pollen, pet dander, etc.) from your air
  • Prevent the spread of viruses and illness
  • Can aid in reducing symptoms of allergies and asthma
  • Not as effective at stopping mold growth

What do they both do?

  • Both of these products are effective at reducing the amount of harmful substances in your air.
  • Both of these work well with the other
  • Both are most effective when paired together to tackle harmful particles in your air

Are UV Purification Systems Safe?

Ultraviolet purification is a long-established technology that won’t pose any threat to your home or the people or pets inside of it. 

Here at Petitt Heating & Cooling, there is nothing we take more seriously than the safety and satisfaction of home and business owners throughout Belle Meade, Cross Plains, East Nashville, Germantown, and more. Our aim with our indoor air quality services is to improve your space and make your air safer to breathe – not put more threats in your way.

That said, trusting a pro to install and maintain this technology is the best way to ensure everything runs as it’s supposed to. Get our techs on the job today, so that you rest easier in the years ahead.

Do UV Lights Prevent Mold Growth?

We’ve mentioned this briefly above, but it’s something that’s definitely worth bringing up more than once – yes! UV lights can help prevent mold growth by preventing the spores from reproducing. That is, if they’re used correctly. Ask your HVAC tech about your options to ensure you get the appropriate technology and equipment for your needs – and to ensure that everything is installed correctly and where it should be.

Also, keep in mind that this isn’t meant to be a cure-all for potential mold problems in your home. While these systems aid greatly in mold prevention, they should be used with other products too, like air filtration systems.

Where Will My UV Lights Be Installed?

Most generally, your new UV light system will be installed in a location where it can most effectively attack microorganisms before they reach your HVAC system. That way, there will be less to filter through and your system won’t be working as hard overall. That said, some systems have the UV lights installed in the supply duct that pushes air into your home, so it’s getting purified right before entering your space.

What you need will depend on your specific needs and layout, which is why consulting with a certified HVAC tech – like one of our team members – is the best approach to take for getting everything just right. Reach out now to get started. We’re here for you and will have your back every step of the way.

How Much Maintenance Do UV Purification Lights Require?

Not much. This is one system that, for the most part, you can have installed, then put out of your mind. That said, there are a few important maintenance things that will need to be done to ensure years of efficient functioning. This includes:

  • Professional Tune-Ups: Having a licensed HVAC tech come out and check things over on a regular basis is important for the health of your UV light system, as well as your HVAC system as a whole. Ask about our maintenance plans, so you never miss a needed appointment.
  • Cleaning: If dust and other particles have built up on the surface of your UV lamps, use a soft brush or cleaning cloth to wipe it down. This will ensure it can still work as effectively as possible. Just turn the lamp off and allow it to cool before doing so to avoid any risk of burns or injury.
  • Replacing the Lamp: UV lamps won’t last forever, and most need to be replaced every 1 or 2 years. Your HVAC tech can ensure everything looks ok (or not ok) during their inspections. Many newer systems have sensors that will tell you when a replacement is in order though.

Remember – these lamps are running 24/7 to fight off harmful organisms in your household, so properly caring for them is a must. Fortunately, that won’t require a whole lot of effort on your part.

Can UV Lights Help in Reducing Odors?

When it comes to reducing odors, air filtration systems are always going to be the most effective of our indoor air quality options. That said, UV lights can offer a great lending hand when tackling those bad smells.

Because UV lights prevent things like bacteria and mold from reproducing, and since these things can often be the culprit of bad odors, it can definitely play a part in keeping your air fresher and smelling its best.

Can UV Lights Help Reduce the Spread of Seasonal Allergens?

UV lights aren’t meant to remove things like pollen and other allergens, but they can prevent the spread of other airborne particles, like mold and bacteria, both of which can trigger allergies and illness.

Your UV light system will essentially work to deactivate these organisms, preventing them from spreading and reproducing. This makes the job of your air filtration system easier, and when you have these two devices working together, you can bet your air will be significantly cleaner – and allergy symptoms will be eased.

Other tips for reducing allergies and symptoms associated with them?

  • Use high-quality and specially formulated filters.
  • Replace your air filters on a more frequent basis.
  • Ask about having a dehumidifier/humidifier installed.
  • Keep floors and surfaces cleaned, scrubbed, and wiped down.

Will My UV Light System Increase the Efficiency of My HVAC Unit?

You bet. The less harmful pollutants your HVAC system has to vent, the better. It’ll work more efficiently, and it’ll last longer too, since it won’t be undergoing as much strain. It’ll also use less energy, which will save you dollars month to month.

In the end, any type of indoor air quality improvements are going to be an asset to your home, HVAC system, and monthly budget. Just make sure you work with a trained tech through it all, so you can ensure you’re getting everything installed appropriately based on your unique needs and goals.

Can UV Lights Be Used in Commercial HVAC Systems?

Definitely – in fact, we encourage it! UV lights can significantly improve the indoor air quality of any space, so this could be a great asset to your business. Your air will stay cleaner, your employees will be better-protected against illness and mold, and your customers will appreciate the fresher air too.
