Report
Jansen did a wonderful job installing AC in our home. Our house is 100 years old and we have a boiler and radiators so it wasn't an easy job. Everyone at Jansen listened to us, responded quickly and the techs doing the installation were very kind to our old house. We couldn't be happier! ~ Julie MacKay, Rockford.

Report
Jeff came out to address uneven heating and cooling issues in our home and suggested a three zone heating system and we could not be happier with the results! Each floor now has its own thermostat and we can adjust the temperature on each floor individually. The bedrooms were normally much too warm while the basement was freezing.not anymore! Thank you Chad, Craig and Shawn for doing such great work! We highly recommend Jansen Heating, Air Conditioning and Electric!
