Frequently Asked Questions About Mini Split Service in O'Fallon, IL
It depends on the age and repair cost. As a general rule, if the repair costs more than 50% of a new system's price and your unit is 10+ years old, replacement is often the smarter investment. Mini Split Repair Master provides honest recommendations we'll give you the repair cost and compare it to a new system quote, with no pressure either way.
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.
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.
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.
