Roof top A/C not cooling properly
Hey all...don't know if this is the best section to post this question but seemed like a great place to start. We purchased a 2007 Cardinal 5th wheel with original Duo-Therm 15,000btu roof air last...

It does sound like the indoor coil collected some frost, and if the compressor did not cycle off during the day, it might have frozen over. By setting the thermostat a little warmer, it will cycle off once in a while, and the fan will remove any frost, and the coil will not freeze.
Yes I have repaired a leak and add more freon to a couple of rooftop units. I have also repaired window A/C units, but it is not low cost. My company charges $150 per hour, so it can be really expensive, a new $750 unit with a full warranty is looking pretty cheap.
But you can find refrigerator repairmen who can weld on a fitting on the copper suction line, and then puncture the line, and add freon. Of course if you have a leak that is 1/2 ounce per year, it will only take a couple of years for it to become low on freon again. The system only holds about 1 pound of freon.
Good Luck,
Fred.
