We had KS Kooling and Heating out on Monday afternoon about 245pm to our office for a quote. Ken gave me a quote for moving some ducks to allow more cool air into the conference room to make it more comfortable for an office. He turned the main offices AC unit down to 64 to get it to kick on and check the airflow. It was at the end of the day and everyone was leaving he got his things and said he would email me a quote in the morning. We turned off the AC like we always do and in the morning turned them back on. The people in my office don't change the temp on the AC units they only turned them on or off, when my boss check the AC a little later in the afternoon because it wasn't cooling, it was still set at 64. We called KS back and they said that they didn't do anything wrong and they didn't damage the AC and he would come back out but he was going to charge us, and if there was a service need we would be charged for that too. We are very displease with this reaction, and this company's immediate denial of responsibility of the actions they took. If he changed the temp on the thermostat he needed to change it back before he left. We called another company out, they said in fact that the unit froze up because it was set to low. We are highly disappointed with this situation and KS refusal to make it right.
