Customer moved forward with repair for cleaning drain line. Added inline float switch to system and cleaned drain line and removed water from drain pan. System back up and running.
Upon arrival customer stated that ac unit had stopped working as of yesterday. After inspection of system found that unit had a drain pan full of water that activated the pan float switch and turned system off. There was a clogged (16x20x1) system filter and qty 2 (14x14x1) clogged filters in the return vents inside home. The system froze due to no air flow. Checked over system by by passing the float switch to ensure unit turned on and everything came on. Blower capacitor is testing bad. The disconnect was by passed and load is hooked into the voltage coming from panel, wires do need to be separated and new disconnect installed. Checked outdoor unit capacitor and contactor tested good with no issues, condenser coils are very dirty. Gave customer estimate to remove water from drain pan, replace bad blower capacitor, clean outdoor condenser coils, add in line float switch and wet pan switch.

Today we came out and did a low calculation on unit 407. Based on the equipment in the lab in the equipment going in, we determined that there is enough power available to add new equipment. The new equipment that is being added will max out the power in this unit. If you want to add more equipment, then you would end up needing to upgrade the service from 150A to 200A or higher. I have left two quotes, the first quote is for adding for dedicated circuits. All four of these dedicated circuits are 208V and require a specialty line and plug for equipment. The second quote addresses an issue with the first two LCMS set ups. The LCMS set ups have a smaller wire running to them. The wire is not rated for the load that the UPS requires. The wire is also on a breaker that is oversized. This however, will not affect the new work that we are quoting to do.
