I had my air ducts clean by precision air. They did a wonderful job. They have fair pricing and they were able to come out fairly quickly and I did not have to wait
I have now hired them to do some ductwork and some AC work and I will leave another review based on that as well

I called Precision Air . To schedule an appointment . To clean my air ducts I had a total of seven vents and they had a special for $45 per event. I had seven vents I told them if they would come out and clean my vents. They made me an appointment for the next day. The technician and his helper Came out and did an excellent job. I was well please and I paid them for the job they did. Hi highly recommend them to anyone that needs a unit or service to be done.

Ken is incredibly transparent, knowledgeable, and always responsive. His follow-up calls are greatly appreciated. Clint is respectful, hardworking, and went above and beyond—coming out late at night and early in the morning to resolve my issues. 5+ stars for both the team and the company!

We called Precision Air after being given their name by a friend. Since we are a commercial account we were directed to Ken who got us set up and on the schedule for the next day. The repair technician showed up on time and was able to get us fixed up quickly. Ken followed up after that and we made a plan to order parts for a different piece of equipment we had been struggling with. Very happy with the service from Precision Air!
