To: Customer in Columbia Md
Prepared By Scott Meenen
After receiving call that Air-conditioning system has failed I traveled to location to check the system and found the following:
Unit was short of refrigerant due to a leak. I did not have time to locate leak but I did recharge the system and determined that the compressor is in good shape and should not give any problems.
After recharging the system I checked the indoor section and found that there is no condensate drain connected to the coil but evidence that at one time one existed. After further examination I realized that the drain had been cut off and for most of the existence of the system the condensate drain has been plugged up by dirt from the system which means that all of the condensate is running into the ductwork. This would cause all of the humidity removed by the system to be re-evaporated back in to the house.
The solution to this problem is to replace the drain piping and clear out the drain. This will solve the problem of water being re-evaporated back into the house and damaging the ductwork.
To install this drain it will be necessary to move some cabinets from the laundry room and a length of 3/4 inch PVC. pipe be connected from the unit drain to the outside.
In addition to the immediate problem at hand I found these other problems:
1: The outdoor unit is sitting in dirt and should be raised up on blocks and all the dirt should be vacuumed out and the unit washed.
2: The disconnect switch needs to be replaced because the old one is loose, missing parts and is badly rusted
3: The system has lost refrigerant due to a leak and should be found. If the leak is located in the indoor coil then the coil should be replaced
4: To optimize the system the indoor coil should be replaced with the largest one that will fit that uses a thermostatic expansion valve plus an electrical tune-up of replacing the contactor, adding a hard start kit, replace any damaged wiring and terminals
DUE: Service call charges for July 11th,= $50
Fix drain, replace disconnect and clean unit $180
To change coil $550
To do everything recommended $780
