Best Air Duct Repair in San Diego CA

I had to authorize time and a half rates in advance in order to get them to come out for a same-day call (because they were booked up), but they made it before 4:00pm anyway, so I didn't have to pay extra.  The technician knew his stuff and was gone in less than an hour after fixing/replacing a $6.50 part - who knew?!  Overall, good service on a job well done - thanks!
