What is the lowest ambient temperature the system can heat down to?Updated 2 days ago

Most standard models can operate in heating mode down to ambient temperatures as low as 5ºF, although their heating capacity typically decreases at such low temperatures. 

In contrast, Hyper Heat models maintain 100% heating capacity even at 5ºF, offering a reliable and energy-efficient heating solution down to 13ºF. Furthermore, their extended operational range allows them to continue heating effectively in environments as cold as -22ºF.
