  • You think you are being a smartass but that’s exactly what heat pumps do. The only functionality difference between an AC unit and a heat pump is a reversing valve.

    But without a reversing valve you could put your AC unit in backwards and heat your house in the winter.

    The whole premise of an AC unit is to take the heat from inside the house and put it outside, leaving you with cooler air inside.

    So in the winter a heat pump simply reverses the flow of the freon and moves the heat from outside to inside. Yes. You are “cooling the whole neighborhood” when you run a heat pump.






  • That’s what I found after researching as well. Now on the opposite side of the spectrum, we bought a house with zero insulation in the attic. Paid $1800 for I think 16" of blown in insulation. Simple return on that was less than 6 months. Next will be crawl space insulation and encapsulation. That’s going to run around $3000 and I expect maybe 2-3 year return on that.


  • We rented a house where the owner decided to replace all the old metal fame single pane windows with new high quality double pane windows.

    He spent something like $30,000 on all the windows and installation.

    Didn’t notice any difference.

    Like, the HVAC bill was basically the same, and the noise was basically the same.

    We may have saved $5-10/mo. on power but that is simply not worth it.
