Is there some reason why heat pumps don't spray some antifreeze/salt-brine on the evaporator to clear/prevent ice? Either alone, or in conjunction with heating.

You seem like the right person to ask, and this idea has been stuck in my head since seeing the technology connections video.
- esaym 6y agoAny kind of antifreeze or salt would be an environment issue, never mind the issue of it corroding metal. Ice build up and "defrost cycles" are not really an issue if managed right. But the issue is people buying the cheapest option and expecting the greatest performance. HVAC tech knowledge is also an issue. Most techs are going to do the bare minimum in order to close out a job and move on to the next project/service call. There is really no incentive for educating end users on how their "system" works.
