Our old furnace was having problems so we looked for a new one. The Coleman was recommended by friends and I called B Carlson. Mario helped us decide and later Alex and Alejandro came out to do the installation. These folks are amazing, professional and perfectionists. Could not ask for any better. I thank you B Carlson, Jeremy, and all the folks at B Carlson. Thank you for the great work and Merry Christmas to all.
