Frequently Asked Questions About Mini Split Service in Dover, IL

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.
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.
With proper professional maintenance, a high-quality mini split system typically lasts 15 to 20 years. Neglecting regular cleanings and ignoring small repairs can cut that lifespan down to under 10 years.
