    For heat pump HVAC systems, the only way to make them efficient enough to meet the requirements that were coming into effect up to now was to make them physically larger. My utility room has zero space left that could fit a larger unit. My current one isn’t looking so hot and is nearly 20 years old. I wasn’t sure what I was going to be able to do when it was going to need replaced. The standard exceeded affordable capabilities of technology.

    As to washing machines. They use less water, but they also take longer and kinda suck, now.

      Huh? The part that does the actual heat pumping (and cooling when AC is on) is outside. Why would the size of your utility room matter?

        The condenser/evaporator, the blower fan, and the air filter is all inside. Larger fan=more efficient. Bigger filter=more efficient. Larger surface area on the condensor= more efficient.

        The pump is a tiny and inconsequential size. A Larger evaporator coil outside helps with efficiency, but it does nothing for the blower motor, airflow restrictions, and the condenser coil the air has to pass through that’s all inside the utility room.
