Heat pumps and an ERV. Both fairly simple but provide hear/cooling and clean fresh air, respectively and both do so efficiently. There really needs to be an advance but that hasn't happened yet and every knowledgeable HVAC person I spoke with said the "advanced" combination units broke down too much and were overly expensive to acquire, fix, and maintain. Make sure your home is air right with spray foam or something like it.
