Excellent experience. Had 4 a/c units get checked out for "preventative" maintenance. He (Dominik) was very friendly, down-to-earth guy, and was fun to talk to, and offered a wealth of information about anything you had questions with, he was very happy to offer that. He stated everything was in spec (all wires pulling correct currents, run-caps at expected values) and was very thorough. He stated they DO NOT work on commission, so there won't up-sell or try to get you to buy something that you don't need. For example, if you are 1/3 lb low on refrigerant, they will only charge you a 1/3 lb to fill it to spec, as it should be. With R22 refrigerant being on average $100/lb, some previous companies charge you the whole lb ($100) even if you needed 1/2lb or 1/4 lb, or 1/8 lb... If any company tries to do that with you, show them the door and the bottom of your foot! I felt he was very honest and it was a pleasure doing business with them. I will definitely use them again for all other services! They charged $65 for first a/c, and $40 for each additional a/c.
