CRE 101 - Current HVAC is a 93Tonne Carrie Chilled Water system w/4Semi 06E Semi Hermetic Compressors.
As the title states...

Just replaced 3 pumps in 2 weeks. I have 4 AHU, two on each floor of the 2 story 29k sf building. I've spent a a decent amount on repairs. The system is old, neglected, etc....My conern is that if I keep spending approx $2k a month on repairs after the first yr of acquisition, I'll have paid approx $120k in 5 years. $2k a month is an aggressive estimate but this is what Ive done and replaced.

One semi hermetic compressor, I have 2 30lb tanks of r22 Freon sitting around which, replaced a blower motor on the AHU and the booster motor on the same AHU. I just replaced a 10HP motor for the pump that pressurizes the system near the chiller. I paid approx $1k for a company to get into the old automation system and set a schedule, now I know how to do that and control when it comes on and off. I'd say I spent nearly $20k on small items that needed to be serviced, or replaced.

Despite all of this the chiller and system could have various failures, and leaks. I spending good money on a bad asset. What would most of you all do since we have the winter coming up and I need to make an adjustment prior to next summer. I have a good idea of how the building behaves, and the pain points. I've lost alot of sleep and time by baby sitting these issues and not focusing on other things.
