Coretemp is hands down the only heating and air company you should use! Richard and his team are the nicest, most professional, most ethical and honest, and highly skilled people you could ever meet. I have been using Coretemp ever since they installed my new furnace and AC unit 6 years ago, after noticing a flood in my furnace room. They promptly responded to my emergency back then and continue to be my only go-to people for all my furnace, AC, and tankless water heater needs. I contact Richard every year to perform my furnace maintenance service. This year I also got them to do a maintenance flush on my tankless water heater, which I had never done before. Through no fault of their own, the hot water valve broke during the service. It had calcified internally from lack of maintenance, and cracked when being turned off. Not only did Richard and Erik rush out to find the parts to fix it (they didn't want me to be without hot water for one second), Richard did not charge me for the parts or labor! And I was kept undated every step of the way.
He always conducts business fairly and with integrity. He goes above and beyond to make sure his clients are happy. 5 star company with 5 star knowledge, skill and customer service!
