when we turn on our AC it takes about four to five hours for it to cool down. Once it cools its cold. Is this normal for it to take so long or do I need to have the AC repaired. Memphis, TN
Install covers over your roof vents and keep them open while you're driving, this will help exhaust the heat. Once at the camp sight leave the vents open for a hour or so to help let the warm air at the ceiling escape while the A/C cools off the trailer.
