I had you come and check my heating system at my tow townhomes. The technician was very professional and courteous and did a great job of explaining a few issues that need repairing. My only complaint, is that you charged me $131.00 to vacuum the water out of the drain pan. That is totally a ridiculous price, as there couldn't of been more than a half a gallon of water and it tool all of 20 seconds. I would've just done it myself except I didn't have a shop vac as this was a rental. I most likely will use your service again, but I will never pay for something like this again!
