About Faszold Service Company


Faszold Heating and Cooling is a family owned business ran by Mike and Kathie Faszold that started in St. Charles County over 39 years ago. We have grown throughout the years and now offer several new services including Geothermal, Solar Energy Solutions, Water Purification Systems, and more. We feel that part of that growth is due to our loyal customers. Through their word of mouth and referrals (the best form of advertising!) we are extremely grateful so we make sure to do everything we can to serve our customers with a smile and meet all of their heating and cooling and comfort needs.

Then & Now

A lot has changed since 1980 (including Mike and Kathie's hairstyles) but Faszold's commitment to their customers certainly has not!

Our Mission

At Faszold, your comfort is our number one priority. Comfort with your air, the technician we send in your home and the no pressure sales process that ensures you receive the best value for your budget.

We strive to achieve your satisfaction on each and every visit, not because it’s our job, but because it’s your home and business!
