We had decided to get our air ducts cleaned & had no idea who to call. We got the Valpak in the mail and there was a coupon for Air Pure Inc. I called & was able to schedule an appointment within a week. When the technicians arrived they were prompt, friendly & very efficient! Michael & his son Josh did a great job! The job took a little more than an hour. They did all the vents along with the dryer vent. And there was nothing for me to clean up. They were truly amazing! The cost was a little more than we thought it would be, but it was well worth it! Michael also gave us some great tips on what to do to try & keep the dust in the house at bay. And he suggested other ideas for our system. I would highly recommend this company if u need ur air ducts cleaned!
