"Arrived and got started right away. I paid him upfront and had to shower and change to head out for evening. I received pictures taken of a portion of the duct, was disappointed I could not see to the end of the vent clean out. My other concern is how the service tech left the dryer vent curled up and partially crushed as he put the dryer back in place, and then took this picture to display it. It would seem obvious that once you saw the vent like that you would correct it. Not happy with that. "

"Your home is not safe with this company. We had service done on 11/12/2025. I noticed that night that medical marijuana was missing from my bedroom. I am a cancer patient. I didn't notice anything else missing and didn't want to put someone's job in jeopardy in this economy. Today, I noticed that $150 was missing from my wallet. I didn't think to check my wallet when I noticed the missing marijuana because it was right by the front door. Who would steal that audaciously? I called the company to report what had happened. I was told they had "received my email a while ago about the medical marijuana and had been passing it around". I never sent them an email, and neither did my husband. Someone else had also been robbed in a similar way. I was transferred to the owner, Joe, who offered to reimburse me $100 "out of his own pocket" if I wanted to come to his office to get it. That offer was rescinded when I expressed my dissatisfaction with it. Nothing is being done. Protect your family."

If you see dust blowing from vents, find mold inside ducts, or notice a spike in your energy bills, it’s time for a professional inspection and cleaning to improve air quality and efficiency.
