HVAC UV Light

At Thomas Hoffmann Air Conditioning & Heating, we offer a free evaluation by an engineer to provide solutions to prevent and reduce the spread of these contaminants in your home or business.

No matter how clean your home or business is, particles will still be in the air you breathe. Mold, bacteria, and viruses can quickly spread through an HVAC system. However, you can remedy this situation by installing a UV air purifier.

I will always call Hoffmans for my air and heat needs. They were out to my daughters house that day and fixed it. It was right before the weekend storm with below zero temps the next day. They saved my daughter and grandbabies. I could never thank them more.

Got a quote over the phone. Everything was explained thoroughly. Dakota, my technician arrived and on time, was very professional and knowledgeable. He didn’t try to upsell or change anything. He did a great job. We can already tell the difference since the ducts and vents were cleaned. Would recommend an use Hoffman again in the future.

Your service technician was very professional and knowledgeable. And did not appear to try to give me bogus information. I truly appreciate his honesty because several other companies did not appear to be honest, obviously wasn’t honest, my gut feeling told me they were not honest and tried to get me to spend $10,000 for a problem that was much simpler to fix. I look forward to you servicing all my properties, and possibly those of the rest of my family.
Response from the owner:Thank you so much for the kind words and great review! We appreciate your support.

⭐️⭐️⭐️⭐️⭐️ If I could give 10 stars, I absolutely would.

Last night our furnace went out unexpectedly, and with three kids in the house, the temperature dropped fast. Giovanni went above and beyond in every way possible. Instead of charging me a late-night service fee, he simply asked, “Are you decently handy?” and offered to walk me through some troubleshooting steps to get our heat back on so my children wouldn’t have to sleep in the cold.

Not only did he guide me through the process, he even FaceTimed me and showed me exactly what to take apart, how to put it back together, and what signals to watch for. It felt like having a real technician standing right next to me the entire time. Thanks to him, our heat was restored within minutes.

In a world where true customer service is hard to come by, Giovanni is a rare find. It is a guaranteed fact that any future repairs, maintenance, and the new heater/AC system we’ll be needing this coming summer/fall will absolutely be done through him. His honesty, kindness, and expertise have earned our business for life.

Highly, highly recommend.
Response from the owner:Thank you, Jeff, for sharing your experience! We're so glad to hear Giovanni was able to help you and your family during that tough situation. Your recommendation means a lot to us, and we appreciate your trust in our services for the future!

I called this company earlier today because I was having a bunch of issues with my HVAC system. They were incredibly friendly and walked me through troubleshooting step by step over the phone. They didn’t even charge me for the call. Thanks to their honest advice, I was able to get things running smoothly again. Really grateful for their help and would definitely recommend them if you want straightforward and trustworthy service. Five stars all the way!

Healthy Climate UV-C Germicidal Lights

UV-C Radiation is germicidal. In particular, the wavelength of 254 nm is incredibly impressive at killing germs, viruses, mold, and bacteria. Fortunately, UV-C radiation can pass through the air without creating ozone, so UV-C lamps can be used in the air to disinfect surfaces.

Exposure to Contaminates

Exposure to mold, fungus, bacteria, and yeast can lead to several health problems, such as allergies and asthma. You may not see them, but these contaminants are in the air you breathe inside your home, and the air quality in your home may be worse than outside.

Exposure to mold, fungus, bacteria, and yeast can lead to several health problems, such as allergies and asthma. You may not see them, but these contaminants are in the air you breathe inside your home. The air quality in your home may be worse than it is outside.

Facts About Mold

The presence of mold in the air is widespread. About 150,000 different types of mold grow indoors and outdoors. Molds play an essential role in the natural environment. However, indoor mold has become a concern due to certain health risks linked to mold exposure.

Mold spores are commonly found in household dust. Some health problems include allergies, asthma, eyes, nose, and throat irritation. Mold can elevate the risk of respiratory infections.

How Does UV Light Help?

Ultraviolet light is germicidal, which means it can break down the DNA in bacteria, viruses, and other airborne contaminants, thus keeping them from growing. The sun’s UV light does this to the air outside. UV germicidal lights connected to your home’s HVAC system can disinfect the air inside without chemicals.
