This company charged my 90 year old mother in law $639,00 , to clean 1 vent and repair her air conditioner. The problem is the air conditioner was not repaired and the work was supposed to be free, according to her existing contract she was to receive 2 free service call / drain pipe cleanings per year. This was exploitation of the elderly and incredibly poor performance . She now has a bucket under her A/C pipes. I have called a different company. User's recommendation: Dont let this company in the door.
