Absolutely. Mini Split Repair Master installs PVC line hide covers (slim ducts) that match or can be painted to match your home's exterior. This conceals the copper refrigerant lines and electrical wires while protecting them from UV damage and weather.
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.
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.
What Customers in Crystal Lake Say About Mini Split Repair Master
"Fast, fairly priced, and they got it right the first time. My Pioneer system was blowing warm air. The tech found the refrigerant line had a pinhole leak at a connection, brazed it properly, and recharged the system. Perfect now."
"Three companies told me my unit was beyond repair and tried to sell me a new one. Mini Split Repair Master's technician fixed it with a $180 control board replacement. I've referred them to everyone I know."
"My heat pump was struggling badly in cold weather barely keeping the house above 60°F. The Mini Split Repair Master tech found the defrost board was faulty. Replaced it and now the system heats perfectly even when it's below freezing outside."
