Had Mr. Rob Wolff servicing our Heating/AC system today. Found him to be extremely knowledgeable and a great communicator. He noticed several settings that while operational, were not at there optimal selections. He explained them as I was wanting to know as much about my system as I could. He realized that I didn't want to know these details so that I could work on the system myself, but rather to be able to know when my system was not operating properly. Cannot say enough good things about Rob and Woods Comfort Systems.
