Wojo's Heating & Air Conditioning are very, very good! We purchased a new furnace and air conditioning unit from them and they installed it. The schedule for installation was supposed to take a day and a 1/2 but the two technicians who installed it managed to do it in just one day! I honestly do not think they even took a break the entire time. They were professional and I was very pleased with how polite and kind they were. Their work area was always kept clean and they took care of anything that needed to be hauled away. They took the time to explain everything about the new system and answered all of our questions. Because of their "great service," I have already recommended them twice.
