A typical tuneup on a standard air conditioning system ranges in price from $70 to $100 as of 2015, according to Angie's List. Some tuneups may cost more, depending on the condition of the system and the amount of time that has passed since the last tuneup.
During a tuneup, a certified heating, ventilating and air conditioning technician cleans the unit and performs a visual and physical inspection of all hoses, connections and mechanical components. The technician also checks the refrigerant level and measures the efficiency of the unit. If the unit needs any repairs or adjustments, the technician usually performs them at the time of the service call.
