[quote=Anonymous][quote=Anonymous][quote=Anonymous]My Mitsubishi Hyperheat system maintained my house at my preferred 68F just fine over the cold snap. This type of unit does not have any auxiliary electric or gas backup. My system is rated to operate at peak efficiency down to 5F. House is single-family, built in 1926. Have done some attic insulation and sealing and windows are ~20 years old, so this isn't a high-performance new build. I think there are lots of cruddy heat pumps out there, but the Mitsubishi cold-weather systems seem to handle this level of cold swimmingly...[/quote] Tell us more about your system. Is it ducted?[/quote] +1 Please tell us more![/quote]
