If you have ever wondered whether it is worth installing a ductless air conditioner, the answer is almost always yes: ductless systems eliminate the need for bulky ductwork while offering superior control over individual rooms or zones.

We work with all leading ductless brands and handle everything from initial system sizing to final commissioning and testing.

• Comprehensive System Assessment and Sizing: We evaluate your space carefully — room dimensions, insulation quality, sun exposure, and occupancy patterns — to recommend the ideal ductless unit capacity for each zone in your home or business.
• Professional Multi-Zone and Single-Zone Installation: Our technicians handle full installation including wall mounting, refrigerant line routing, electrical connections, and drain line setup, ensuring everything meets Quebec safety codes and manufacturer specifications.
• Rapid Diagnostics and Repair: From refrigerant leaks and frozen coils to faulty sensors, compressor issues, and remote control malfunctions, we identify and resolve problems quickly to minimize your downtime.
• Energy Efficiency Upgrades: We integrate programmable controllers, smart thermostats, and zoning schedules to help you maximize savings on your electricity bill while maintaining perfect comfort in every room.
• Safety and Performance Verification: After every installation or repair, we perform thorough operational checks — including pressure testing, airflow balancing, and electrical safety inspection — to ensure your system runs safely and efficiently.
• Seasonal Tune-Ups and Maintenance: Regular preventive maintenance keeps your ductless system running at peak performance. We clean filters, inspect coils, check refrigerant levels, and verify all electrical components during each visit.
