Ductless HVAC Systems in Boulder

Ductless mini-split systems are a wonderful opportunity to achieve ideal comfort anywhere. For those hard to heat or cool areas, renovations, additions, residential or commercial applications, the compact equipment and flexibility of location accommodate every challenge just beautifully. Find the right fit for your needs by getting in touch with Welzig Heating and Air.

As the name implies, ductless air conditioners and heat pumps don’t require ductwork. A single, quiet outdoor unit links to one or multiple indoor air handlers by way of a slim conduit. The installation process necessitates little beyond a three-inch hole in an exterior wall and access to electricity. Welzig Heating and Air typically has your new system up and running in a matter of hours, and there’s no mess to clean up or walls to patch.

Satisfied Customers
They Speak For Us

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!


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.
