Sometimes something so small can stop a unit from working properly. This capacitor is the culprit not allowing this hybrid tank to work.
General maintenance on all items even just 1-2 years old is recommended. This tank is only 2 years old and the capacitor is out of range to keep the heat pump side of the tank to work right.

Call to now to schedule your annual maintenance inspection.

Sometimes things just happen!
This outdoor unit from 2023 had a burnt out PCB board because of a short from another appliance in the home-tripped the breakers etc. I have to replace this part under warranty. But note- labor is not covered. Manufacturing only covers the parts to get replaced but labor to have a technician put it in, is not covered, just like any appliance in your home.

How AC Units Work:

Most standard air conditioners can only cool a home about 20 degrees below the outside temperature. If it is 85°F or hotter outside, your AC cannot physically reach 65°F.Lowering the number does not make the air blow colder; it just makes the unit run longer.

Risks of Setting it to 65°F

High energy bills: Your system will run non-stop trying to reach an impossible goal.
Frozen coils: Continuous running in hot weather can freeze the indoor evaporator coils and break the system.

Mechanical strain:
The compressor works too hard and can suffer permanent damage.

These are just some risks when you try to turn the AC down that low.

Side note: if your system is not cooling the house and it’s getting hotter, turning the thermostat down even lower will not solve the problem.
