I have used One Hour Heating and Air Conditioning for years! They are very reliable and they know what they are doing! They come out twice a year to service my furnace and air conditioning and I have never had any problems with either system. I never have to worry about them, ever! Eon with One Hour Heating and Air Conditioning was recently out to service the air conditioning unit and I was in the garden working and had the opportunity to watch him while he worked. I had never seen him before and he is a younger technician and I was impressed with his work. He was very thorough in his cleaning and really did a first rate job! This company puts everyone else to shame! Well done!
