Answers to Common Questions
View All FAQsHow much does it cost to replace a ductless mini split system?
Replacing a ductless mini-split is priced after an on-site assessment by our HVAC technician. Exact cost depends on the number of indoor wall units, line-set length and routing, electrical needs, and brand selection. We install and replace ductless systems and service all major ductless brands including Mitsubishi, Daikin, LG, and Fujitsu. If leaks are found, we repair line sets rather than just adding refrigerant, which can affect scope. Financing options and membership plans are available to help manage costs in Austin and nearby areas.
