1. The first step in repairing your Air Conditioning unit and preventing freezing is to inspect the cold air line for any tears or damage to the insulation. Pay extra close attention to the connection at the venting system and near any bends in the line. If your Air Conditioner is already not working you can simply look for an ice build up on the line. The cold line can be followed from your AC unit into the house and will lead directly to your venting system. It should be wrapped in black insulation similar to what is shown in the picture. 2. If you find any damage, or in some cases improper repair (see picture) you will want to replace the entire section of insulation. Turn off your Air Conditioner and begin running a dehumidifier in the basement or attic area that houses your AC lines. Remove the damaged area as well as several inches in either direction of the insulation. Remove any tape, glue or other material that is in contact with the pipe. 3. Once the pipe section is clean of insulation and debris, cut a section of replacement insulation to fit the gap. Make it a point to cut the section to be as tight as possible without overlapping. Wipe off any moisture and attach the new section of insulation. Wrap the entire area in moisture barrier such plastic sheathing or tyvec paper. Make sure to extend the moisture barrier at least a few inches passed the new section to cover the ends of the original insulation. Wrap it tightly and then use either electrical or duct tape to attach it firmly.Air Conditioning Repair Hattiesburg 4. Check the joint between the Air Conditioning line and the venting system for any wear and replace the insulation if necessary. Continue running the dehumidifier for a few hours to be sure that the air is depleted of moisture and then turn your Air Conditioning system back on. It should run more efficiently and you should be free of frozen pipes for several years. If the AC was not working before you began the project and continues to not work after completion, contact an HVAC specialist as your problem may be mechanical in origin. Tips & Warnings When applying the moisture barrier be sure to use a dry towel to remove any moisture from the pipes and surrounding areas. If you notice any breaks to the cool AC line call an HVAC specialist immediately as you may be leaking coolant. Be careful when cutting away old insulation not to damage or score the coolant line with your utility knife.
