Last summer when it was super hot and the upstairs AC broke we called the people at Robinson Heating and Air Conditioning to come and fix the unit. The unit was over 15 years old so we had to replace it but honestly they did an awesome job. They also work on the downstairs unit whenever we have problems with it as well. They even fixed the cooling unit when it was leaking freon as well. This is a great company that cares about their customers!
