Mckinnon Heating Cooling

I called them to come to my house because it looked like my hot water tank was leaking. I told them there was a puddle around my tank. I called on a Saturday evening around 8:00 pm. They told me someone would call me back. Nobody called. I called again at 11:00 pm and they told me that someone would call back. I stayed up to 1:30 am on Sunday, and nobody called back. I got a call Sunday morning at 9:30 am, and a technician came at around 10:45 am. He was at my house for about 20 minutes. He said that it wasn't the hot water tank, it was the furnace. He wrote that on the work order he gave me, and left. I called another technician for my furnace, which was under warranty. The technician came and said that it was NOT the furnace, it was the air conditioning. He said that if the water tank was leaking, there would be a flood in my basement, and that the McKinnon technician should have know that. They charged me $203.40 to come for nothing, as they should have know it was not the hot water tank leaking ( I bought the hot water tank from McKinnon), so they came so that they could charge me for doing nothing and diagnosed the problem INCORRECTLY. Also, by telling me it was the furnace, which it WASN'T, there was an additional technician charge. STAY AWAY FROM MCKINNON!!!!!
