Yes, but you need a "hyper-heat" or cold-climate model specifically designed to operate efficiently in sub-zero temperatures. Standard models lose their heating capacity when temperatures drop below freezing. Mini Split Repair Master can install units rated to produce heat even at -15°F.
Mini Split Repair Master technicians in Union, Missouri are trained and certified to service all major mini split brands, including Mitsubishi, Daikin, LG, Fujitsu, Samsung, Gree, Pioneer, Mr. Cool, Bosch, Friedrich, Carrier, Trane, and more. We carry common parts and control boards for the most popular models.
First, replace the batteries in the remote. If it still doesn't work, try using the manual override button under the indoor unit's cover. If it turns on manually, the receiver board in the indoor unit has failed. If it doesn't, the main control board is likely dead.
That "dirty sock" or vinegar smell means mold, mildew, or bacteria has built up on the indoor coil or in the drain pan. It requires a professional deep cleaning and sanitization to restore healthy indoor air quality.
