The 2 technicians from Air Current came to clean the coils and do the maintenance on our HVAC unit. They were only there 21 minutes. I don't think they even did what they were supposed to do. It cost me $85 instead of the $150 that the girl on the phone said it would cost. I think they didn't clean the coils. Normally I am very pleased with their service, but this was a rental property and I had never seen the 2 guys they sent this time. I usually have the same technician at my personal home. I just don't know how they could have possibly cleaned the coils AND do the maintenance of the HVAC unit in 20 minutes. I just didn't feel a lot of confidence in those 2 guys.
