Modern Purair Calgary

William and MondernPur air is the only company I trust to clean the vents right. If they do it for the children's hospital, they are good enough for me. My house goes from smelling like "old dog" to fresh and clean -- you will notice the difference right away. I love WIlliam, he is very thorough and conscientious getting every nook and cranny. He spent well over his allotted time here to get the job done right. We have pets and extreme allergies and couldn't survive without ModernPurair. I highly recommend the sanitzer in the vents and furnace as well to kill all the germs!! Well done. Thank you William, you are a real treasure with a super amazing work ethic!! Well done!!
