Precision Installation
We mount the new indoor air handler(s), install the outdoor condenser unit on a level pad or wall bracket, run new refrigerant line sets and communication wiring, and make all electrical connections to code. Proper line set sizing and flare fittings ensure a leak-free system.

After installation, we charge the system with the correct refrigerant amount, verify operating pressures, test all zones for proper airflow and temperature control, and program your remote or smart thermostat. We walk you through operation, filters, and maintenance best practices.
to a New Mini-Split
Modern mini-split systems are dramatically more efficient, quieter, and smarter than units from 10+ years ago.
Your System is 10–15+ Years Old
The average mini-split lasts 15–20 years with proper maintenance. Beyond 10–12 years, efficiency degrades and replacement parts become scarce. A new system pays for itself in energy savings within a few years.
Rising Energy Bills with No Explanation
Follow the “5,000 rule”: if the repair cost × system age exceeds $5,000, replacement is the smarter investment. Compressor failures, refrigerant leaks, and PCB board failures on older systems often signal the end of useful life.
Frequent or Expensive Repairs
Follow the “5,000 rule”: if the repair cost × system age exceeds $5,000, replacement is the smarter investment. Compressor failures, refrigerant leaks, and PCB board failures on older systems often signal the end of useful life.
Inconsistent Temperatures & Poor Performance
Struggling to reach set temperature, rooms that stay hot or cold, unusual noises, or ice buildup on the outdoor unit are all signs that the system can no longer perform as intended.
R-22 Refrigerant System
Mini-splits manufactured before 2010 may use R-22 (Freon), which is now banned and extremely expensive to source. Replacing with an R-410A or R-32 system eliminates this cost and compliance risk entirely.
