How Often Should You Service Commercial HVAC Units?

If you’re responsible for a commercial property, you already know how important heating and cooling systems are. Whether you manage an office tower, retail plaza, industrial facility, or healthcare center, your HVAC units are the backbone of comfort and functionality. But here’s a critical question: how often should you really service those commercial HVAC units?

Some building owners wait for something to go wrong before calling a technician. Others stick to a calendar-based maintenance plan. But the smartest property managers follow a well-planned commercial HVAC service schedule. And it pays off.

From energy savings to extended system life, let’s walk through how often you should be scheduling service and what each visit should include.

Why a Commercial HVAC Service Schedule Matters

Imagine running a business where your HVAC system fails in mid-winter or during a summer heatwave. Productivity drops, tenants complain, and the repair bills are anything but pleasant. This is why having a structured service schedule isn’t just smart, it’s essential.

A consistent HVAC maintenance schedule helps you:

• Catch small issues before they grow• Avoid surprise breakdowns• Improve indoor air quality• Lower energy consumption• Extend equipment lifespan• Maintain warranty compliance

Without a plan, you’re rolling the dice with one of your building’s most expensive and essential systems.

General Rule: Twice Per Year is the Minimum

The baseline industry recommendation for most commercial HVAC systems is two comprehensive maintenance visits per year, once in the spring and once in the fall.

Spring service prepares your cooling system for summer, while fall service gets your heating equipment ready for the cold months. These checkups are key to ensuring optimal performance through temperature extremes, especially in climates like Edmonton’s.

But in high-demand environments like data centres, restaurants, or hospitals, more frequent inspections, quarterly or even monthly, may be necessary.

Factors That Influence Your HVAC Service Frequency

Not all commercial buildings are the same. The ideal service schedule depends on a variety of factors, including:

• Type of HVAC system (rooftop units, boilers, chillers, VRF systems)• Building size and occupancy levels• Indoor air quality requirements• Local climate conditions• System age and maintenance history• Business type (medical, retail, industrial, etc.)

A manufacturing plant with heavy ventilation needs will require a more aggressive service schedule than a low-traffic office space.

That’s why companies like Soul Mechanical in Edmonton offer customized maintenance plans based on your building’s unique needs.

What’s Included in a Commercial HVAC Service Visit?

Every visit is designed to keep your system safe, efficient, and reliable. While the exact steps may vary depending on your system type, a general service checklist includes:

General Tasks• Replace filters and update filter change date• Inspect fans, belts, and electrical connections• Test unit operation and safety controls• Clean accessible components and unit exterior• Assess unit life expectancy and overall condition

Cooling System• Check refrigerant levels and compressor operation• Inspect and clean condenser coils and fan blades• Monitor for oil or refrigerant leaks• Verify operating temperatures and airflow

Heating System• Clean and inspect burners and heat exchangers• Test ignition systems and carbon monoxide detectors• Inspect blower motor, belts, and bearings• Confirm furnace or boiler safety controls are operational

Airflow and Controls• Inspect ductwork for blockages or leaks• Verify thermostat calibration and building automation settings• Monitor economizer operation where applicable

High-Traffic or High-Sensitivity Facilities May Need Monthly Checks

If your building supports sensitive operations or experiences high foot traffic, you may need monthly or bi-monthly inspections. Examples include:

• Medical clinics• Restaurants• Server rooms or data centers• Warehouses with fluctuating temperatures• Schools and daycare centers

In these cases, the air quality, comfort, and safety stakes are higher, so more frequent service is a must.

Warning Signs You Need HVAC Service Sooner

Even with a schedule in place, don’t ignore these red flags:

• Unusual noises from the unit• Uneven temperatures across rooms or floors• Rising energy bills without explanation• Poor airflow or musty smells• Thermostats that don’t respond• Visible moisture or refrigerant leaks

These are signs your system may be struggling and needs immediate attention, regardless of what the calendar says.

The Role of HVAC Service Contracts

A service contract with a trusted HVAC company like Soul Mechanical can help keep you on track without the guesswork.

Service contracts often include:

• Regularly scheduled maintenance• Discounted emergency repairs• Priority service during peak seasons• Maintenance logs and system reports• Budget forecasting for future HVAC upgrades

This kind of agreement helps you avoid the scramble and stay one step ahead of breakdowns.
