High Velocity HVAC Specialists

Specializing in high velocity HVAC systems, Welzig Heating and Air offers home and business owners in Boulder, Colorado unique opportunities and benefits. For older properties lacking convention ductwork, this modern innovation is designed to retrofit without damage. There’s no major teardown necessary, no sacrifice of valuable space and no compromise of architectural stability or aesthetics. A high velocity system is the answer you’ve been looking for.

The primary advantage of high velocity heating and cooling is the mini ducts. Just two inches in diameter, the especially skinny tubing is flexible enough to snake through existing walls and accommodate obstacles such as pipes, studs, rafters and wiring. The vents are also much smaller, typically just 5” across. They are round, available in a wide range of styles and offer freedom of location.

Lower Utility Bills with High Velocity HVAC

With a high velocity system, the hot or cool air travels from the compressor or heat pump to an air handler, enters the room at a high rate of speed and circulates especially quickly. It creates aspiration which raises or lowers temperature more rapidly than with other types of systems. The system doesn’t need to run as long, using less energy. Plus, the mini ducts are insulated, further protecting against waste. You’ll appreciate lower utility bills right along with ideal comfort.

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.

Clare

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.
