Heat Pump Compressor Diagnosis - Building Fire
Some HVAC package unit compressors were exposed to high heat during a fire in an adjacent structure. Concerns have been raised that the HVAC equipment was damaged due to the heat. One technician raised the concern that the equipment needs to be replaced due to possible acid formation in the oil. The equipment looks completely fine. There are no charred or melted parts. We plan on taking oil samples to check for acidity.
1.If high levels of acid are found, then will the units require replacement, or could the refrigerant and oil be removed and flushed from the system, and replaced?
2. If acid is found, will the compressors or any other components require replacement or adjustment?
Any help or advice would be appreciated.
