About five days ago I had an overflow from the reservoir in my AC unit. I telephoned Todd, because of prior reviews that I saw on his website. Todd was extremely busy, however he took the time to troubleshoot my problem on the phone. I followed his instructions and checked my filter, which was full of dirt. Todd thought the issue might be a clogged pipe, as opposed to a problem with the unit. I attempted to rectify the issue, but was unable. I telephoned Todd again and he suggested I find the exit point for the pipe to see if there was blockage there. I was unable to locate the exit point which, I later found out, was due to it being covered over by stucco. Anyway, Todd was too busy to come by for three days, due to his call load. In the interim I had someone else come out and fix the problem, which was in fact a blocked pipe. To make matters worse I forgot to cancel my appointment with Todd and he showed up on my door at the appointed time. Todd accepted my apology graciously and did not charge for my not canceling the appointment, which I thought i would have to pay for.
