I called requesting a tune-up and cleaning of my A/C coils because my A/C smells a little musty. The guy who helped me on the phone was kind and forward about pricing and offered a couple of options. (Prior to calling Benefit Air, I had called a few other a/c contractors and none of them were up front about fees. The man I spoke with at Benefit Air detailed what I should expect.)
I ended up purchasing a service contract with Benefit Air and they were even able to send a tech out the same day. The tech (Mike) was on time and very kind. He quickly surveyed the A/C unit (on the roof) and showed me a picture of the current state of the evaporator coils. He said that everything looked good (besides the dirty coils) and did the coil cleaning and tune-up in about 1-1.5 hours.
The foul odor is gone now! I am very happy with the service, and I highly recommend these guys. They did a great job at setting my expectations and then delivered outstanding service.
