I had to call A+Derr to have someone come out and clean out a drain pipe on my indside unit. Just a week or so earlier I had that unit serviced as part of my maintanance agreement. I would have thought that when the unit was serviced that the serviceman would have checked the drain pipes. The second serviceman charged me for a "call out" on cleaning out the drain. I did purchase two filters from him and he was very nice. I just feel that the "call out charge should have not been charged.
