Expert Evaluation

When your ductwork is not sealed properly or develops leaks, this can lead to extensive energy loss, low air quality, and a system that fails to perform efficiently. Some signs to pay attention to include costly energy bills, uneven temperatures, excessive dust and allergens, and noisy system operation. You’ll find that our NATE-certified experts follow a comprehensive duct-sealing process. Our technicians will first conduct a complete assessment of your ducts which includes the use of advanced diagnostic equipment and pressure tests to identify the source of leaks. We will seal any gaps using industry-leading sealants and ensure all seams, joints, and connections have a tight seal. To ensure proper air distribution in your ductwork, we’ll adjust registers, dampers, and grilles if needed. Upon completion of the duct-sealing process, we’ll test your system to ensure it runs in optimal condition without any leaks.

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!
