We went to make the upgrade this year to get central air conditioning in our house. The service at first was not that great. The salesman that came to our house was quite rude. We almost did not use this company because of him. At one point he even stated that he was "wasting his time". However they had the product we wanted and could get it done fairly quick so we went with them anyway. The air conditioner works great and have not had any problems yet.
