Professional Ductless Mini Split Installation & Repair
Room-by-room heating and cooling for additions, garages, and spaces standard ductwork can't reach.
Ductless Comfort for the Rooms That Need It
Not every room fits neatly into a home's existing ductwork — additions, converted garages, and older homes are common examples. A mini split system lets you heat and cool individual spaces without extending ductwork.
We install and repair both single-zone and multi-zone mini split systems, and can help you figure out how many indoor units your space actually needs.
- Upfront pricing
- Licensed & insured technicians
- No ductwork required
What We Handle with Mini Splits
Installation and repair for ductless systems.
Refrigerant Leaks
Leaks between the indoor and outdoor units can reduce performance — we locate and repair them.
Drain Line Clogs
A clogged drain line can cause leaking or shutdowns, so we clear and inspect it.
Indoor Unit Communication
When the indoor and outdoor units stop communicating properly, we troubleshoot the connection.
Remote & Controller Issues
If your unit isn't responding correctly to its controller, we'll diagnose the issue.
Ice Buildup
Ice forming on the indoor or outdoor unit usually points to an airflow or refrigerant issue.
