It’s the largest residential model that Ecoer makes. The home is a 3-bedroom, large but nothing crazy. The installers said they erred on the side of too big, rather than too small, and that’s corroborated by my back-of-the-napkin math and Google searches indicating that “too big” is standard practice in the HVAC industry. So in theory, it shouldn’t be a lack of power. I think it’s poorly optimized. From what I’ve been reading, the pressure in the lines is very important. I have no idea if they are pressurized properly. The unit apparently has sophisticated monitoring of the line pressure, but the IoT gateway has no end-user access which is a huge red flag for me that I wasn’t aware of before it was installed.
