The pluses are that they come out promptly and are very nice and "professional. "
My major complaint is the charge for Freon. My unit uses R22 which is being phased out for 410. These folks wanted to charge me $75 per pound of freon. The whole can only cost between $300-350 (family in business in another state.) I don't mind a business making a profit but since I needed 14 pounds I could have bought three cans. That is not profit that is rape.
