IAQ Information

Over the course of time, dust, debris, mold, and other contaminants will build up in your ductwork system. With state-of-the-art equipment, our professionals will carefully remove all of these contaminants from your system so you don’t have to deal with them recirculating throughout your breathing air. Our cutting-edge air purification systems are designed to remove similar debris, but also will eliminate the threat of dangerous pathogens in your environment, ensuring you have superior air quality. It’s also important to consider humidity in your environment. When your environment is too humid, you can deal with mold growth and health concerns.

Satisfied Customers
They Speak For Us

Bob came out to look at our swamp cooler and was remarkably helpful and professional. Not only did he give me a knowledgeable diagnosis, but he also taught me a lot in the process. We’ll be calling him for all future needs with our cooling system.


Dave Kaplan-Gomez and James Miltersen installed my new Tankless Water Heater. Both were polite and professional. Care was taken not to damage anything in my house which I really appreciated. I use Welzig for all my HVAC needs and highly recommend them.


Our 23-year-old A/C system ran out of “borrowed time” and became too difficult to continue maintaining. With great advice from Casey Welzig,, we replaced the old system with a Bryant Evolution A/C system. Max Loustaunau and Seth Bernhardt did an excellent job with removing the old system and installing the new one. Both of them are great to work with — very professional and very personable. We are really amazed at how much better the new system works!
