When we arrived we turned the system on and everything came on properly and ran properly. We tested all the electrical components, refrigerant charge, temperature split and everything was working properly and even brought down the temperature 2 degrees during the hottest part of the day. One thing we found is that the emergency drain pan was full of water. There are no float safety switches on this system which do recommend. I spoke with the client and she said we were good to remove the water and clear the drain lines which we did. I also added a vent after the trap to help the water flow better out of the system. I did let the client know that this system is 18 years old and it could be having issues when working all day long in the heat but as of right now it’s working properly.
