Did a superb job of cleaning the vents and duct work. Don't be fooled by the low cost coupons from other businesses. These guys know their stuff

They were very professional and took their shoes off upon entering my home. They asked if there was a pet that they needed to take precautions of getting out of the house. They worked in the bathroom first so that I could put my cat in the room so she would be safe. They explained everything that they were going to do and answered all my questions. I have already handed out their business cards already. I will definitely call them when it's time to have my vents cleaned again!

Cornerstone IAQ is simply excellent. They arrived exactly (to the minute) as they said they would, showed me before and after duct pix, and offered sound advice on other related actions I could take. They are worth every dollar spent. I recommend them to anyone needing their HVAC ducts cleaned. Hats off to Mike and Jason....

Mike and Jason were true professionals. They walked through the house and quoted a price before work began. They explained what they would be doing and provided appropriate discussion and informative pointers along the way. We would highly recommend them.
