Frequently Asked Questions About Mini Split Service in Carol Stream, IL

For maximum energy efficiency, set the thermostat between 72-78°F in summer and 68-72°F in winter. Unlike traditional systems, mini splits use inverter technology and work best when you set a comfortable temperature and leave it alone rather than constantly adjusting it.
As a general rule, you need about 12,000 BTUs (1 ton) to condition a 500 square foot space. However, this varies heavily based on insulation quality, ceiling height, and window layout in Carol Stream, IL. Mini Split Repair Master provides free sizing consultations.
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.
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.
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.
