Hello, My name is Jimmy Welzig. I am the owner of Welzig Heating and Air. I started our company in 1994, along side my bride Jalene, after working in this industry for many years prior. We are family owned and operated, located in Longmont.

I was born in Philadelphia but raised most of my youth here in Longmont with my father. I have been married to my bride since 1988, and together we have 5 children together ranging in a 21 year span. Our little miracle baby, Faith, has Down's syndrome and has opened our eyes to a whole new world. Family means everything to me.

I believe that the same values I share with my own family should be shared with your family. We incorporate trust and our high standards in every aspect of my business. I firmly believe the difference between a good company and a bad company is how they respond to mistakes as well as how to avoid mistakes.

At Welzig, we have developed a system with high standard procedures, along with the latest technology, in order to give our customers the highest quality of service and quickest response to any and all situations. Our technicians, installers, and even office personnel are required to take the latest technical training, classes, and certifications. In addition to Welzig's requirement NATE certifications and factory training, we have built our own state-of-the-art training center for our technicians and office personnel to ensure up-to-date training.

Every job is unique and personalized, so we build custom fabrication for every job right here in our own shop. Any employee that show up at your door will be clearly marked in a Welzig Uniform, insured and bonded, and have the correct tools and training to complete the job in a timely and professional fashion.

Welzig is constantly adapting and changing as we listen to our customer's desires and reviews. We have been blessed to receive the Daily Times Call Reader's Choice Award for 10 years. We listen to our customers and our every growing rating and reviews have confirmed our system works and it will work for YOU!

We strive to provide superior service and solutions. Cooling, heating, and cleaning the air you breathe.
