Four seasons replaced my ac unit before the heat of summer. The summer down here in Houston is extremely hot and humid and not very comfortable. I was shocked to learn that our regular ac unit was not working because it was already starting to get hotter. Living without ac in Houston is dangerous to your health, as you could die of heat stroke. However, I contacted this company and they replaced my ac and checked my house for any place that my ac was leaking out of. In other words, they maximized the potential that my ac could cool. They were very efficient and professional. I recommend them to everyone that needs a new ac or work on their current unit. Great service and attentive work. I give them 2 thumbs up here in the nice coolness of my humble abode.
