Frequently Asked Questions About Mini Split Service in Maryville, IL

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.
A musty or foul smell from your mini split in Maryville, IL is almost always caused by mold, mildew, or bacteria growing on the indoor blower wheel or evaporator coil a common problem in humid climates. Mini Split Repair Master performs a thorough deep-clean chemical treatment that eliminates odors and restores healthy indoor air quality.
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.
While you can and should wash the reusable plastic mesh filters yourself every month, deep cleaning the delicate aluminum coils and internal blower wheel requires specialized HVAC bibs, chemicals, and pressurized water. DIY cleaning frequently bends the coil fins or damages the electronics.
This usually indicates a refrigerant leak, extremely dirty air filters, or a failing compressor. Check your filters first. If they are clean, the system has likely lost its charge. Call (877) 359-0825 immediately, as running the system low on refrigerant will permanently damage the compressor.
