If you’ve ever wondered what’s included in a commercial HVAC service, you’re not alone. Many facility managers, building owners, and operations teams ask this exact question, especially before peak heating or cooling seasons. Fortunately, PSL Patrick Sprack Ltd. is here to make the answer clear and actionable.
In this post, we’ll walk through everything you can expect from a full-service commercial HVAC maintenance visit. We’ll also explain why each step is essential for keeping your system safe, efficient, and code-compliant.
1. Full System Inspection
First and foremost, we start with a comprehensive inspection of your entire HVAC system. This step is essential, as it helps identify any issues before they escalate.
What’s included:
- Checking all HVAC units (rooftop, split systems, furnaces, heat pumps)
- Examining belts, motors, fans, and bearings
- Testing thermostats, control panels, and shutoffs
- Listening for unusual sounds or vibrations
Without regular inspections, small problems often go unnoticed until they become emergencies. Therefore, this step sets the foundation for reliable operation.
2. Filter Replacement and Air Quality Review
Next, we turn our attention to air filters and indoor air quality. These components affect both comfort and safety, especially in industrial or high-occupancy spaces.
What we do:
- Replace or clean filters to improve airflow
- Inspect intake and return vents
- Test humidity levels and CO2 if needed
- Check for dust buildup, mold, or contaminants
Clean filters reduce energy use and improve air quality. In addition, they help prevent HVAC strain and premature breakdowns.
3. Electrical and Refrigerant System Testing
After that, we inspect all electrical components and, where applicable, your cooling system’s refrigerant levels.
This includes:
- Checking wires, fuses, relays, and breakers
- Measuring voltage and amperage
- Testing safety shutoff devices
- Verifying refrigerant pressure and inspecting for leaks
Faulty wiring or low refrigerant can damage your system and increase energy costs. As a result, this part of the service ensures safe and efficient performance.
4. Duct and Ventilation System Review
While some service providers overlook it, we take time to inspect your ductwork and ventilation systems, because airflow isn’t just about temperature. It’s about system balance and safety, too.
What we check:
- Leaks or gaps in ductwork
- Loose connections or damaged fittings
- Obstructed vents or dirty grilles
- Damper functionality and air balancing
Since we fabricate ducting in-house, we can quickly repair or replace problem areas, often within the same visit. Therefore, downtime is reduced and quality control stays high.
5. Maintenance Report and Service Log
Finally, after every visit, we provide a detailed maintenance report that outlines everything we completed and any recommendations going forward.
What you get:
- A written checklist and service summary
- Notes on potential future issues
- Repair recommendations (if needed)
- Suggestions for improving system performance
This report supports planning and compliance. In other words, you stay ahead of issues while keeping stakeholders informed.
How Often Should Commercial HVAC Be Serviced?
Generally, twice a year is ideal, once in spring (before cooling season) and again in fall (before heating season). However, if your facility operates year-round or in high-demand conditions (such as mining, healthcare, or manufacturing), we recommend quarterly service to prevent disruptions.
