Air Current Inc. is a great company! Unfortunately, this last time the guy came out he was not able to fix my furnace. Reason being is that my system is too old now and they do not make that type of freon that goes in it anymore. The technician took the time to explain it to me thoroughly that freon nowadays is made with better chemicals that will not hurt the environment. Because my system is over ten years old, it could not be fixed. He was nice enough to refer me to a company that could give me a quote to replace it. I have used Air Current Inc. for about three years now and I will continue using them. They were so quick to respond. I called them around 11:00 AM that morning and they had someone out by 3:00 PM that very same day. I was not expecting that after all the trouble people are having right now with the Winter storms. I would recommend them to anyone. They are really a good company!
