HVAC for Commercial Properties
Commercial property managers are typically responsible for base building HVAC systems. Understanding the maintenance requirements — and what tenants are responsible for in their own units — prevents disputes and deterioration.
Rooftop units (RTUs) are the most common commercial HVAC configuration. Quarterly filter changes, coil cleaning, refrigerant checks, and belt inspections are standard maintenance items typically included in service contracts.
Maintenance and Compliance
Condenser coil condition directly affects energy efficiency. Dirty coils cause the system to work harder, increasing energy consumption and accelerating compressor wear. Annual coil cleaning is non-negotiable.
Drain pan and condensate line maintenance prevents water damage. Blocked drain lines overflow drain pans, dripping water through ceilings and causing significant interior damage to tenant spaces.
Getting Expert Service
Refrigerant handling is regulated under Canada's Environmental Protection Act. Only certified technicians may handle refrigerants. Verify contractor certification before allowing refrigerant-related service.
RTU curb condition matters. Deteriorated roof curbs allow water infiltration around the unit. Annual inspection of curb sealing prevents roof leaks attributed to HVAC installation.
Preventive maintenance contracts for commercial HVAC provide predictable costs, prioritized service response, and documentation of maintenance history — important for tenant relations, insurance, and asset valuation.
