Question: What outdoor temperature is safe to test and turn my air conditioner on for the first time before summer?

Answer: I would strongly recommend turning on and testing your air conditioner early before it gets real hot. I would recommend waiting until the temperature outside is above 75 degrees. Yes, make sure your air conditioner is running properly before the weather gets real hot and all the service companies are back-logged for several days. I would recommend allowing the unit to run for 15 minutes to make sure everything is OK. You can do a feel test on the larger suction line to make sure your unit is charged up properly. If you stick two fingers on the suction line (after it runs 15 minutes) under the insulation, on most air conditioners it should feel like a cold coke can right out of the refrigerator if the unit is charged up properly. If the suction line is not cold or not cool then I would recommend that you get someone to check your refrigerant charge to make sure you are charged up properly for the summer. The biggest cause of for compressor failure is a unit that is low on charge. This allows the compressor to run hot, melts the motor windings inside the compressor and eventually causes compressor failure. I would not recommend calling a service tech to check the charge on an air conditioner until the temperature is above 75 degrees.
