5/5

Stunned!!

September 13, 2025

This heat pump has reduced my monthly bill from $400 to $120 p/month during our Texas summer. It is so quiet, I went out to check on it many times in the beginning to see if it was actually operating. Our home stays at our desired temperature without ever touching the thermostat. If by chance the unit starts while I am standing near it (even beside it), I do not have to raise my voice to talk over it. The system design appears to have allowed a clean, accessible, and effective installation from our dealer. I have not needed a warranty claim so I am unable to rate the process at this time.
