    All Survey Responses for Moore Home Services
    Verified Enviro Heating & Air Conditioning, Inc. Customer, 1 of 199
    "I like that they are local. It's a husband and wife who work together and the wife takes care of everything, answers the phone and distributes the workers. The husband fixed a furnace a couple of years ago and coaches little league, which is a plus. He stopped on his way home on the weekend and fixed it when no one else would. I'm going to be a lifelong customer as long as they are in business. They are a local, family run business and they explain to me everything that they are doing. If they adjust the jets, they tell me, show me everything and let me watch." - David M.
