We had just bought a new house and figure we should have the A/C serviced for ($400). Its been about a week. Our A/C was barely pushing any air out of any of the vents. We check the air filter, not only was it black it had rust spots on it. The side of the Unit was frozen due to the lack of air getting through the system. The wrote their notes on a piece of paper which we didn't sign the things mentioned on here with a price were in excess of $800 in parts which were not needed. I walked to ACE and got a $5$ air filter and let the system thaw overnight. Work fine now.. He did not mention anything about that being a major problem. I figured a "Service" meant they would actually perform some sort of work. He also failed to mention the overflow pump did not work either. Google what to check on your A/C unit for 3-5 service tips. Apparently that is worth $400 dollars.
