Steps for a good A2W heat pump replacement

Would you flush and replace antifreeze, (Cryotek) in an air to water heat pump replacement (initial install 10 years ago). Older unit had 2 condenser failures.

You can test the glycol it may have become acidic. I would cut open the old condenser and see why it failed.

If the water and glycol is 10 years old and with failures I would change it especially with a new unit. Start fresh.

unsure how the two relate- two compressor failures and 10 year old antifreeze. The pressures and temperatures dictate a healthy or poor running refrigeration cycle. And some other factors like short cycling, acidity

you have a 10 year old air to water system? Maybe you mean traditional outdoor unit with basic air handler with hot water coil?

Curious what you have, air to water is just now getting momentum.
