• Professional System Sizing and Installation: Our certified technicians assess your space and recommend the right capacity ductless unit for every room or zone, then complete a clean, code-compliant installation with minimal disruption to your property.
• Comprehensive Repairs: From refrigerant leaks and frozen coils to faulty fan motors, drainage issues, and unresponsive remote controls, we diagnose and fix all ductless air conditioning problems quickly and accurately.
• Energy Efficiency Upgrades: We integrate smart thermostats, multi-zone configurations, and inverter-driven compressors to maximize your energy savings and reduce your monthly hydro bills throughout Terrebonne, Mascouche, Repentigny, and Laval.
• Safety Inspections and Performance Testing: After every installation or repair, we conduct thorough system checks to verify proper refrigerant charge, airflow, electrical connections, and overall cooling performance in compliance with Quebec standards.
