My AC unit is approximately 20years old according to the information on the units and the technician that came out. And it's time for a replacement they usually last 10-15 years. They have denied the claim to replace the one that's out saying it's not due to normal wear and tear. Just anything to not cover the expenses. The woman at the customer service was super rude and unprofessional. Before you decide to go with this company Please check the BBB site and check out the lawsuits against them.
