Custom Preventative Maintenance for All-Weather Efficiency
Because rooftop units are entirely exposed to Toronto’s harsh, changing weather elements year-round, they experience heavy wear and tear that can lead to sudden, costly operational shutdowns. Kobist Air provides specialized, proactive maintenance protocols designed to protect your equipment from the elements, ensuring your system runs efficiently while drastically lowering your monthly commercial utility bills.
Multi-Point Mechanical Tune-Ups: Thoroughly cleaning condenser coils, checking refrigerant charges, and replacing heavy-duty belts to prevent sudden system failure during peak seasons.
Economizer Optimization: Calibrating your RTU’s economizer to pull in cool outdoor air when temperatures allow, significantly reducing the workload on your compressors and cutting cooling costs.
Weather-Proof Sealing & Drainage Inspections: Checking outer panels, clearing roof drains, and inspecting unit curbs to eliminate the risk of water penetration and structural damage to your roof.
