Air Conditioning Start-up and Seasonal Maintenance Checklist

This convenient Air Conditioning Checklist has been designed to help maximize reliability, economy, and fuel conservation in the operation of this equipment.

Information from our files indicates that a great many failures take place at start-up or early in the cooling season because of inoperative controls or safety devices. Most of these accidents could have been prevented if a little more attention had been paid to readying the equipment for service or when the equipment was taken out of service at the end of the season. We therefore recommend that the following measures be taken to ensure a trouble-free cooling season and reduce the likelihood of equipment malfunction.

The tips offered here are intended to complement and not replace the recommendation of the equipment manufacturer. It is recommended that operators consult with their original equipment manufacturer for instructions related to their specific model and operating conditions.
