We handle comprehensive preventative maintenance across all commercial equipment tonnage, focusing on airflow stability, TSSA combustion safety, and energy optimization.
Quarterly changes of commercial V-belts, pleat filters, and high-efficiency MERV racks to maintain critical airflow and optimal indoor air quality.
Annual inspection of economizer dampers, enthalpy sensors, and actuator motors to ensure the "free cooling" cycle activates correctly, drastically lowering utility bills.
Chemical washing of condenser and evaporator coils to restore heat transfer capacity, lower head pressures, and prevent compressor overheating during summer peaks.
Tightening high-voltage connections, monitoring compressor amp draws, testing gas manifold pressure, and checking heat exchangers for cracks to ensure TSSA compliance.
How we engineering proactive comfort for your facility, from initial audit to quarterly execution.
A licensed technician audits all rooftop assets, documenting make, model, tonnage, filter/belt sizes, and current mechanical condition.
We design a PM contract specifically around your budget, building usage, and equipment lifecycle—semi-annual, quarterly, or custom frequency.
On scheduled dates, our certified technicians execute the tailored multi-point technical checklist, submitting digital completion reports.
We provide annual HVAC budget analysis, warning property managers about nearing equipment lifecycles or necessary repairs before they become emergency costs.

Common questions building operators and facility managers ask about commercial HVAC maintenance contracts.
Preventative maintenance lowers commercial energy costs by ensuring systems run optimally, prevents up to 95% of unexpected breakdowns, extends equipment lifecycle by up to 30%, and is generally required to maintain manufacturer warranties. It also ensures indoor air quality and tenant comfort remain stable.
Atrium Air agreements are custom, but standard inclusions include replacing air filters and V-belts; inspecting electrical contactors and tightening terminals; cleaning condenser coils; verifying refrigerant charge; checking economizer operation; inspecting gas manifolds and flame sensors; and auditing the heat exchanger for safety (TSSA compliance).
There is no "standard" cost because agreements are tailored to the facility. Pricing depends on the total tonnage of the equipment, the number of units, the difficulty of roof access, and the frequency of service (quarterly vs. semi-annual). We offer complimentary asset audits to provide an accurate, transparent annual PM quote.
Light retail, medical offices, and corporate professional spaces are generally covered under semi-annual (two times per year) agreements (Spring/Fall). High-demand environments such as commercial kitchens, manufacturing plants, distribution warehouses, or 24/7 retail plazas require quarterly maintenance (four times per year) to manage extreme dust or airflow load.
Yes. Our commercial division is fully registered with TSSA (Technical Standards and Safety Authority). Every preventative maintenance visit on gas-fired commercial equipment includes specific TSSA safety checks, including inspecting heat exchangers for dangerous fractures and ensuring gas burner combustion safety.
