What Common Commercial Jobs Involve

Every building is different. Here is what the most common commercial jobs involve, so you know what to expect before we visit.

🏗️
Rooftop unit replacement on a plaza unit
Lifting the old unit off the roof and the new one on, fitting a curb adapter if the footprint has changed, reconnecting gas, power and ductwork, then start-up and testing. The swap is planned around your opening hours.
🏢
Office zoning upgrade
Splitting one large system into zones so boardrooms, private offices and open areas are controlled separately, with smart thermostats set to your business hours.
🍳
Restaurant tenant fit-out
Make-up air to replace the air the kitchen exhaust removes, dedicated cooling for the kitchen line, and heating and cooling for the dining room, timed to your fit-out schedule.
🩺
Clinic or professional office
Individual temperature control for treatment rooms or private offices, with installation booked after hours so appointments carry on.
🏭
Warehouse or light industrial
Larger rooftop units, often 20 tons and up, sized for high ceilings and the heat lost through loading doors.
📋
Multi-tenant plaza maintenance
One contact for every unit on the roof, spring and fall inspections, a written report for each unit and one consolidated invoice for the property manager.
