However, it’s important to note that the heating function is supplementary and works best when outdoor temperatures are above 41°F, which might limit its use in colder climates. Also, at 56 pounds, the unit might be a bit heavy for some users to install by themselves. The remote control and washable filter are practical additions, contributing to ease of use and maintenance.

The heating capacity is an added bonus for cooler days, providing supplemental heat to maintain a comfortable temperature indoors.
