eracode:Every piece of electrical goods -- heat pumps included -- will have insect damage excluded from warranty claims. It's even excluded by insurance. You really must keep up maintenance of such appliances, keeping the spaces around it clean and monitored.

My heat pump failing after three years and the supplier demanding $1650 - about half its original price - to fix it. Highway robbery. Yes, ants got onto the PCB and fried it, but that's still a huge amount of money for some electronics.
Surely it’s not unreasonable to expect the electronics in outdoor equipment to be ant-proof?
