"The technician was on time and courteous. My A/C wasn't blowing any cold air, so he checked the air handler first, then checked the heat pump. The freon was very low, 1.5 pounds in a 3.5 pound system, so he charged the unit with freon. The air was fine after that. He did a check for leaks from the evaporator coil "on the house" and showed me that the coil was losing coolant from several spots. He recommended that an engineer come have a look about a system replacement since it was impossible to tell how long the coolant was leaking - the main issue being that the coil had several leaking spots.
Overall the service went well. The price was a function of the high price of freon ($90 or so per pound), so it could have been any HVAC company getting dinged on the price issue.
