Mini splits are generally up to 30% more efficient than central air because there is no ductwork for air to leak out of. They also allow for independent room temperature control (zoning), meaning you aren't paying to cool or heat empty rooms.
Turn off the unit using the remote control, then go to your main electrical panel and flip the dedicated circuit breaker for the mini split to the OFF position. Wait 5 full minutes, turn the breaker back on, and try the system again.
The condensate drain line is clogged with dirt, mold, or algae, causing the internal drain pan to overflow. Turn off the unit immediately to prevent drywall damage and call Mini Split Repair Master to have the line professionally cleared and the pan sanitized.
