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.
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.
Repairing a refrigerant leak typically ranges from $200 to $500 depending on the location of the leak (indoor flare joint vs outdoor coil) and the amount of refrigerant required to correctly recharge the system.
A properly maintained mini split system in Wilmington, DE lasts 15–20 years.
