Overall, I had a very good experience with One Hour Air Conditioning & Heating. I recently used this company for the first time and they provided an excellent service for my air conditioning unit. They came in and added some Freon. They also cleaned the unit very well. I would describe the technicians as professional and easy to work with. The only issue I had was that I thought that the cost for the service was very expensive considering what they had to do. For that reason, I wouldn't recommend them to other people nor would I use them again. But I am happy that everything is working well with my air conditioning unit.
