    FAQ"S

    Commonly Asked Questions.

    The most common commercial AC systems in Ontario include rooftop units (RTUs), variable refrigerant flow (VRF) systems, and split systems. The right choice depends on your building size, occupancy levels, and energy efficiency goals. RTUs are ideal for large office buildings and warehouses, while VRF systems are great for multi-zone properties like hotels or schools.

    Upgrading to a high-efficiency AC system reduces energy costs, improves indoor comfort, and ensures compliance with modern refrigerant standards. Newer models use eco-friendly refrigerants, operate more quietly, and often qualify for Ontario rebate programs, lowering both installation and long-term operating costs.

    Commercial AC systems should be serviced at least twice a year—once in spring before cooling season and once in fall. Preventive maintenance includes coil cleaning, filter changes, refrigerant checks, and airflow testing. Regular servicing improves energy efficiency, reduces breakdown risks, and extends system lifespan. 

    Signs include inconsistent cooling, rising energy bills, frequent breakdowns, unusual noises, and outdated refrigerants like R22. If your system is over 12–15 years old or requires constant costly repairs, replacement with a high-efficiency model is usually the most cost-effective solution.

    Yes. Many Ontario businesses can access utility rebates and federal incentives for upgrading to high-efficiency AC systems. These programs reduce upfront costs while promoting sustainability. LG Mechanical assists businesses with rebate applications to maximize available savings.
