I wouldn’t do it again!




Great technician but the technology they are using is not good. After he cleand my ducts the house was full of dust sitting everywhere.We were sneezing for 2 days. We had to spend another $350 to buy air purifiers and let them run nonstop! Over all, the company is great, their technician is excellent but the way they clean ducts is not the best way!!!
