Provides all the features I was looking for
A little disappointed
April 13, 2026
Don’t use it much but when I did it warmed up my garage and did a decent job cooling it down during last summer’s heat wave. I feel misled by the dealer after finding out the lowest heat setting was 60 degrees after I made it clear I wanted something to keep my garage temperature in the 40s until I get in there and fill my wood burning furnace. Also very disappointed to find the unit is made in China and doesn’t even come with a Carrier Corporation logo badge attached?? Only guessing that the Chinese manufacturer makes the units for several different brands??
Works great; very effective!
