Great service under warrantee

Called Dibiase in the morning - Kurt and crew were here to fix leak and were finished PDQ with report and invoice ($0) issued by 2.15pm. Kurt took the time to explain the issue and what corrective action they had taken. Can't ask for better.

Went up on roof to outdoor heat pump. Hooked up gauges and had no refrigerant in the system. Troy supplied a bottle of 410a. Started adding refrigerant and found that there was a hole straight through the compressor. Heat pump will need the compressor replaced to get system back in operation. Will let our office know the findings and let them know when we can replace the compressor.

Found system low on charge. R-22 pressures were 129/28 with 0 subcooling. We were out in April and refrigerant pressures were ok. System must have a decent refrigerant leak. Explained to homeowner the process is if he was going to jut add charge and leak dye to the system this will help locate the leak but if leak ends up in indoor coil, coil will be $4000 to $4500 to replace. Provided estimate to add refrigerant with leak dye. Heat pump system is a 2004 and highly recommended to replace heat pump system. Set up appointment with office to have bill come out to give an estimate. Homeowner also showed me a room upstairs that never has cooled right and was curious about a ductless system for this room.
