Commercial HVAC FAQs
How often should commercial HVAC equipment be serviced?
Most commercial systems benefit from maintenance on a quarterly or scheduled basis because they run far more hours than residential equipment. Regular service reduces unexpected downtime, keeps energy costs in check, and extends equipment life.
What is a rooftop unit (RTU)?
A rooftop unit is a self-contained, packaged HVAC system installed on a building's roof. RTUs are common in commercial buildings because they free up interior space and keep maintenance access off the sales or work floor.
How can I lower energy costs in my commercial building?
Consistent maintenance, programmable or networked thermostats, economizers, and sealing duct leaks all reduce energy use. An on-site assessment identifies where your building is losing the most efficiency so improvements target the biggest savings first.
How is the right size of commercial system determined?
Proper sizing comes from a load calculation that accounts for square footage, occupancy, equipment heat loads, insulation, and ventilation requirements — not just floor area. Correct sizing avoids short-cycling, uneven temperatures, and wasted energy.
