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.
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.
