All-electric house owner here. 2x Carrier heat pumps, ducted air handlers. One of the carrier units is 13 years old and going great. Electrostatic filters on the air handlers. The house was built in the 50s and renovated in 2010, doubling the square footage. That's when they put in the oldest unit. Idk if it has to do with the mid-Atlantic temperature swings on the marginal seasons, but this time of year the house will get weirdly cold around 6/7pm, so we bump up the heat a couple degrees. It resets to schedule after two hours. The system has a hard time keeping up if it stays below 20 for an extended period of time, but that just means it holds somewhere around 65ºF instead of 68ºF. We're not near seasonal wildfires so air quality is never an issue for us. In fact I notice when we leave the house for the day and come back several hours later, the air in the house has a reassuring "neutral" smell (sealed house cycling old air uninterrupted). We also have a whole-house fan, a relic from the original build, which is incredible when you want to cycle in fresh air periodically. More homes should have these. Anyway, high seer home-scale heat pumps are just pricy things, but they do work well and efficiently in their existing form. The thermostat we use is also by carrier and is _fine_. I don't see anything here that's a significant improvement from our own setup, but they do look nice. We have a big house. If we wanted to be more energy efficient at this point, we'd need similar setup in a smaller house. I don't think nice looking residential mechanicals are going to help the transition to cleaner energy sources any faster. Sorry.
