Where Ductless Mini-Splits Make Sense
Mini-splits are ideal for room additions, finished attics and basements, garages, sunrooms, and older homes without ductwork. They also let you control comfort room by room, so you stop paying to heat and cool spaces no one is using.
Technical Expertise and Accurate Diagnostics
Mini-split performance depends on correct sizing, refrigerant charge, and line set installation. Our EPA Section 608 certified technicians size each zone, mount the indoor heads for even airflow, route and pressure test the line set, and verify charge by manufacturer specification. New systems are AHRI matched with documented SEER2 and HSPF2 ratings, and electrical work follows the National Electrical Code.
Signs You Need Mini-Split Repair
- Reduced heating or cooling from one or more indoor heads
- Water leaking from an indoor unit
- Ice on the outdoor unit or the indoor coil
- Error codes or flashing lights on the indoor head
- Unusual noise or odor during operation
Our Installation and Repair Process
We assess the space, recommend the right number and size of zones, install the indoor and outdoor units, and commission the system. For repairs we diagnose the fault, explain it clearly, and quote the work before we begin.
Verifying Performance After the Job
We confirm refrigerant charge, check airflow and condensate drainage, and test each zone so your system runs quietly and efficiently.
Why Professional Installation Matters
Improper charge or a leaking line set reduces efficiency and can damage the compressor. The U.S. Department of Energy explains the efficiency benefits of correct installation in its ductless mini-split guide.
