Commercial HVAC services we deliver to your building

Rooftop Units (RTU) Installation, Repair & Maintenance
Rooftop units demand a different approach than residential split systems. RTUs combine heating, cooling, and ventilation into a single package exposed to Ontario’s freeze-thaw cycles, which means component failures affect entire floors or zones simultaneously. Our process starts with a full operational assessment of your existing RTU, including refrigerant charge verification, economiser function testing, and control board diagnostics. When replacement is warranted, we size the new unit to your building’s actual load requirements rather than defaulting to a like-for-like swap. Every RTU installation includes proper system commissioning so the unit performs at its full potential from day one.

Commercial Boiler Piping & Maintenance
Commercial boiler systems involve complex piping networks, expansion tanks, and zone controls that residential contractors rarely encounter. We handle boiler inspections, piping repairs, circulator pump replacements, and full boiler installations for office buildings and multi-tenant properties. Our G1 Gas Fitter Licences qualify both owners to work on commercial gas-fired boiler systems, and our repair-first philosophy means we’ll restore a functioning boiler rather than push a premature replacement.
Commercial Ductwork & Renovations
Tenant turnover and building renovations often expose ductwork problems that have been accumulating for years. Undersized ducts, disconnected sections, and poor transitions create pressure imbalances that no amount of equipment upgrades will fix. We design and install commercial ductwork that matches your building’s airflow requirements, including modifications for new tenant layouts. Static pressure testing confirms that the completed system delivers balanced air distribution across every zone.

Condo Corporations & Apartment Buildings
Common area HVAC in multi-unit residential buildings requires coordination with property managers, condo boards, and building schedules. We service hallway ventilation systems, lobby heating and cooling units, parking garage ventilation, and shared mechanical rooms. Our dual-hub model with operators in both Holland Landing and Georgetown means we can respond to buildings across Newmarket, Aurora, Richmond Hill, Bradford, Milton, and Brampton without long travel delays. Transparent communication with your property management team continues until every issue is resolved.
Snow Melt Systems
Hydronic snow melt systems protect commercial entrances, loading docks, and parking ramps from ice accumulation. We install and maintain glycol-based snow melt piping connected to your building’s boiler system, including sensor calibration and seasonal startup procedures. Properly commissioned snow melt systems reduce slip-and-fall liability while eliminating the ongoing cost of manual snow removal from critical access points.
Commercial Air Conditioning Installation, Repair & Maintenance
Office buildings and retail spaces depend on consistent cooling to maintain occupant comfort and protect sensitive equipment. We install, repair, and maintain commercial air conditioning systems including packaged rooftop cooling units, split systems for server rooms, and multi-zone configurations. As a Certified Trane Dealer and Installer, we can source commercial-grade cooling equipment backed by manufacturer warranties. Our commissioning process verifies refrigerant charge, airflow balance, and thermostat calibration before we consider any installation complete.
How we approach every commercial HVAC project
Commercial buildings can’t afford guesswork. Our process is structured so that every decision, from initial assessment through final commissioning, is documented and communicated to your team.
- 01
Building assessment and scope review
We evaluate your existing equipment, ductwork, and building layout. For rooftop units, this includes refrigerant levels, electrical connections, and control sequences. You receive a clear written scope before any work begins.
- 02
Repair-first evaluation
If your equipment can be restored to reliable operation, we’ll recommend the repair. Replacement is only suggested when repair costs approach or exceed the value of new equipment. Honest recommendations, not unnecessary sales.
- 03
Installation or repair with minimal disruption
Commercial work is scheduled around your building’s occupancy. We coordinate with property managers and tenants to minimise noise, access disruption, and downtime during business hours.
- 04
Proper system commissioning and handoff
Every installation is commissioned and tested to verify it operates at full capacity. We walk your building manager through the system controls and provide documentation. The job isn’t done until your system performs as promised.
Is a commercial HVAC contractor the right fit for your building?
Hiring a residential-only HVAC company for commercial work is a common and costly mistake. Rooftop units, commercial boilers, and multi-zone ductwork require different training, different tools, and a different process than a home furnace swap.
Building type
rooftop units, shared mechanical rooms, and multi-zone systems require commercial-grade expertise and 313A Refrigeration Mechanic qualifications
Scheduling complexity
occupied commercial buildings need coordinated work schedules that minimise tenant disruption
System scale
commercial equipment operates at higher capacities and pressures than residential systems, demanding proper load calculations and commissioning
Accountability
property managers and condo boards need documented communication, written scopes, and commissioning records for their files
When it fits
- Your building has rooftop units, commercial boilers, or multi-zone HVAC systems that require qualified mechanical contractors
- You manage a condo corporation, apartment building, or commercial property and need a contractor who communicates directly with your management team
- You need HVAC service across York Region or Halton Region and want a locally owned company with operators in both areas
When it doesn’t
- Your facility requires industrial process cooling or commercial refrigeration for food service operations
- You need restaurant kitchen exhaust or walk-in cooler/freezer service
- Your project involves industrial manufacturing HVAC or large-scale plant ventilation
If your building’s HVAC goes beyond a residential furnace and air conditioner, you need a contractor whose process matches the complexity of your systems.
Common questions about commercial HVAC service
What types of commercial buildings does White Pine Mechanical service?
We service office buildings, retail properties, condo corporations, apartment buildings, and multi-unit residential buildings throughout York Region and Halton Region. Our commercial work focuses on rooftop units, commercial boilers, common area systems, and commercial ductwork. We do not service industrial facilities or commercial refrigeration.
Can you work on rooftop HVAC units?
Yes. Rooftop Units (RTU) Installation, Repair & Maintenance is a core part of our commercial service. Both owners hold 313A Refrigeration Mechanic and G1 Gas Fitter Licences, which are required for commercial rooftop unit work involving refrigerant handling and gas-fired heating components.
Do you offer maintenance contracts for commercial properties?
We provide scheduled maintenance for commercial HVAC systems including rooftop units, boilers, and common area ventilation. Regular maintenance catches small issues before they become expensive failures and helps extend equipment lifespan. Contact us to discuss a maintenance schedule tailored to your building.
How do you minimise disruption to tenants during commercial HVAC work?
We coordinate scheduling with your property manager to plan work around building occupancy. Our commitment to transparent and continuous communication means your team knows exactly what’s happening at every stage, from initial assessment through commissioning and handoff.
Do you service buildings outside Georgetown and Holland Landing?
Absolutely. We travel throughout surrounding communities including Newmarket, Aurora, Richmond Hill, Bradford, Milton, Brampton, and surrounding areas across York Region and Halton Region. Our dual-hub model with operators in both Holland Landing and Georgetown means faster response across the entire service area.
