DuctMasters USA review: Inspection

Tech saw where all the vents were, I explained to him about my fly infection, we talked, he wanted to meet my friend we drove to her house stayed there aprox 1/2 on the way back he started quoting me different prices 2500 to 3000. He never did an inspection, never even looked at the vents told me I needed a deep cleaning for 3000. I said no he asked what I could afford. Finally he said for 300.00 he'd clean one bedroom vent and the main vent for 300.00 I wanted the 199.00. He said 199 is one vent only look at ad
