Mike was the technician who came this time and based on what he did, it appears that we have not been receiving what we paid for in the past. When he first entered our furnace area, he just looked around and noticed there was a crack in our water heater exhaust. He stated that we would look after that later. This time, I saw parts of our equipment that I had never seen before and at one time he even had the blower assembly out and cleaned every blade. It was amazing what mike took time to do which included the removal of several parts and thoroughly cleaned them. After everything was back in place, he then took time to test the unit to ensure us it was working at top performance. He then did the same marvelous job with our fireplace and made sure it was also in great working order before going forward. The next thing was our air conditioner and again, I saw parts I had never seen before. He even opened the electrical compartment and showed me the mouse that had died in there. There is no way of telling how long the mouse had been in there as that is the first time that area was ever checked.
