We can diagnose and repair issues that other contractors might guess at. Whether your mini-split isn't heating, cooling, or showing an error code, we'll get it working properly.

Ductless Repair Questions Answered
Common questions about ductless repair from homeowners throughout Central Ontario.
Why is my mini-split leaking water inside?
Water leaks usually indicate a clogged condensate drain line—a common issue that's typically straightforward to fix. Less commonly, it can be a dirty evaporator coil or a tilt issue with the indoor unit. We can diagnose and resolve the problem.
What do the error codes on my mini-split mean?
Each brand uses different error codes. Common codes indicate communication errors, sensor problems, refrigerant issues, or component failures. Our technicians can interpret codes for all major brands and diagnose the underlying issue.
How often should ductless systems be serviced?
We recommend professional cleaning and inspection annually—more often in dusty environments or with heavy use. Homeowners should clean or rinse filters every 2-4 weeks during heavy use periods.
Why does my mini-split smell musty?
Musty odors typically indicate mold or bacteria growth on the evaporator coil or in the drain pan. Professional cleaning resolves this and improves air quality. Regular filter maintenance helps prevent recurrence.
Can you repair all brands of ductless systems?
Yes, we service all major ductless brands including Mitsubishi, Daikin, Fujitsu, Lennox, LG, Samsung, and others. Our technicians receive factory training and stay current on all brands.
One of my indoor units isn't working but others are fine. Why?
In multi-zone systems, individual indoor units can fail independently. Common causes include communication issues, failed indoor unit components, or blocked airflow. We can diagnose and repair the specific unit.
Ductless Repair Maintenance Tips
- Clean or rinse filters every 2-4 weeks during heavy use
- Schedule professional deep cleaning annually
- Keep outdoor unit clear of debris, snow, and vegetation
- Watch for unusual sounds, odors, or error codes
- Ensure indoor unit has clear airflow (no blocking furniture)
- Don't ignore water leaks—they indicate drain problems
