One Hour Heating and Air did a fantastic job. I received several estimates from other air conditioning companies and One Hour was by far the best deal. Their service promise is outstanding. I have a great warranty and service plan for the future. I can rest assured if I have any issues in the future they will be addressed in a timely manner. As a side note, they brought me window a/c units for the few days until they could install my new system. They put them in the windows and removed them after the new unit was installed.
