Old unit was original to the house (1989). Previous level pay was $343/month. New amount is $193.

BTW, also got a new gas furnace at the same time and the gas bill dropped from $85/month to $60.

  1. Source: This is a picture of my bill, in which the power company includes the current and previous years’ useage.

  3. Out of curiosity what did the upgrade cost and/or what’s the expected payback time from the net savings?

  5. Without knowing the average outside temperature, it does not tell you much. Central Texas summer was over 10 degrees cooler this year over last year. I did not change my HVAC unit, but I have seen similar savings.

  6. Depending on the price of the work, seems like it’ll only take a couple years to pay for itself through the savings. Very nice, do make sure you stay on top of basic maintenance to avoid service calls though.

  7. In certain regions heat pump can drive even more savings.
