I chose this company because I saw in Youtube that it received an award for Top Duct Cleaning and it also advertised $99 for 10 ducts cleaned. The technicians who performed the air duct cleaning were friendly and answered my questions. Total charges reached $320.68 which I believe is too much [$99 for 10 ducts and $12 for every additional duct, $39 for the A/C, $59 for the Benefect disinfectant, waste handling for $14.79 and taxes]. I did not expect that the job would total to $320+. The technicians however gave me a free new filter good for 2 months use since my old one needed to be replaced. When the technicians were putting away their tools, I inspected the wall vents since they did not return the covers. One wall vent was not cleaned, so I cleaned the visible and accessible part myself. The technician told me the A/C was working so I checked the floor registers close to me [about 3 of them] and noticed mildly cold air coming out. Then technician showed me how to turn off the A/C on the wall thermostat. After almost a month when the season became warm, I turned on the A/C again and noticed the same mildly cold air at the start but slowing down and not getting cold after more than 15 minutes. I checked the compressor and found out that it was not running. I believe that the technician run the A/C without turning on the compressor because I'm sure nobody from my family touched the compressor. Then I checked all the floor registers and found one with almost no air coming out. When I went to see the ducting, there was air leaking on joint which needed fixing and duct tape.
Recommendations to customers: 1. Run the A/C for at least 30 minutes with the duct cleaning company to detect any possible problems; 2. Check all floor register and other vents and make sure that they are all clean and working; 3. Make sure the technicians return the covers of the wall vents and walk through with the technicians to inspect all floor registers and wall vents. The charge of $59 for the Benefect was just too high.
