I just had a 37 and 27 year old Carrier heat pumps replaced this last June. The 37 year old was leaking and parts were not out there. The 27 year old was chronically costing me between $200-$400 each year and the HVAC company made me an offer I couldn’t refuse to replace both.
The installer asked about smart thermostats and I said pass. Programmable or old type but no smart anything. My July power usage dropped like a rock from last years, but my bill went up nearly $20 monthly FJB!
FJB...
