As summer arrives, the pressure is on—especially for your commercial building’s HVAC system.
Unlike residential homes, commercial properties have much larger demands. Your HVAC system isn’t just keeping people comfortable—it’s also protecting equipment, keeping tenants happy, and helping your building meet safety and compliance standards. When summer temperatures rise, your system needs to perform under pressure.
Even top-of-the-line HVAC systems can struggle when heat and humidity hit their peak. Components run longer. Energy usage spikes. Minor issues that were invisible in spring can suddenly lead to breakdowns when your system is pushed to its limits.
In this blog, we’ll walk through how summer affects commercial HVAC systems, the warning signs that your system might be under stress, and why scheduling a tune-up early in the season is one of the best things you can do for your building—and your budget.
Why Summer Is So Demanding for Commercial HVAC Systems
Commercial buildings face much heavier HVAC demands in summer than homes do. Here’s why:
- Longer days and higher heat mean your system starts earlier in the day and runs late into the evening.
- Higher occupancy during business hours adds body heat and internal load to your building.
- Lighting, computers, and machines all generate heat, further increasing the need for cooling.
- Higher humidity makes your system work harder by removing moisture from the air in addition to lowering the temperature.
All of this puts extra stress on compressors, motors, fans, and electrical components. If your system hasn’t been serviced recently, that added pressure can expose weak points fast.
How High Temperatures Stress HVAC Systems
1. The Compressor Works Overtime
Your system’s compressor is like the engine of a car—it moves refrigerant through the system to remove heat from the air. In summer, it’s working harder and longer, especially if filters are dirty, refrigerant levels are low, or the coils are clogged.
2. Fans and Motors Are Pushed to the Limit
These components circulate air through your building. If anything restricts airflow—like a dirty filter or blocked vent—fans have to run faster and longer, wearing them down prematurely.
3. Dirty Coils Reduce Cooling Power
Your condenser coils release heat collected from inside your building. When they’re covered in dust or debris, the system becomes less efficient and has to work harder to cool the same space.
4. Electrical Issues Get Worse in Heat
High temperatures can make existing electrical problems worse. Weak capacitors, loose connections, and worn relays often fail when the system is under full load.
Warning Signs That Your System Is Struggling
Before a full breakdown happens, your system often gives off early warnings. Be on the lookout for:
- Inconsistent temperatures: Some rooms too warm, others too cold.
- Long run times: The system is always on but not reaching the desired temperature.
- High energy bills: Usage spikes can point to inefficient operation.
- Complaints from tenants or staff: Discomfort or poor air quality are warning signs.
- Unusual noises: Grinding, clanking, or hissing means something could be failing.
- System alerts or fault codes: If you have a Building Management System (BMS), pay attention to the warnings.
Catching these signs early can help you avoid an expensive failure later.
Why Early Summer Tune-Ups Are a Smart Investment
Think of an HVAC tune-up like routine maintenance for a car. You wouldn’t skip an oil change before a road trip—and you shouldn’t skip a tune-up before summer.
Benefits of a pre-summer tune-up include:
- Finding small issues before they grow: Technicians can spot trouble areas like loose wires, low refrigerant, or dirty coils early.
- Saving energy: Clean and calibrated systems work more efficiently, lowering your monthly bills.
- Extending equipment lifespan: Proper care helps major components last longer.
- Avoiding emergencies: A working system means no disruption to your operations—or your tenants’.
- Improved comfort: A properly tuned system cools more evenly, quietly, and consistently.
What to Expect During a Commercial HVAC Tune-Up
At TY Construction, a comprehensive summer HVAC tune-up includes:
- Checking refrigerant levels and adjusting if necessary
- Cleaning condenser and evaporator coils
- Replacing or cleaning air filters
- Inspecting and tightening electrical connections
- Lubricating moving parts
- Calibrating thermostats and checking control settings
- Testing all motors, fans, and compressors
- Evaluating ductwork and airflow
- Reviewing system performance and making recommendations
Every building is different, so we tailor our approach based on your system’s design, age, and operating requirements.
What One Missed Tune-Up Could Cost Your Facility
Imagine this:
It’s the middle of July. A regional office building is running at full capacity. Employees are working, clients are visiting, and the indoor temperature keeps creeping higher—even though the thermostat is set low.
Suddenly, the HVAC system shuts down. The building manager scrambles to call for emergency repairs, but with demand high during the summer, the earliest appointment is several hours away. In the meantime, productivity drops, tempers rise, and a few tenants start making calls about breaking their leases due to poor conditions.
When the technician finally arrives, the issue is traced back to a clogged coil and a failing motor—both of which could’ve been caught during a routine pre-summer inspection.
The cost? Thousands of dollars in repairs, lost business hours, and tenant frustration.
This type of situation is completely preventable. With a simple HVAC tune-up at the start of the season, small issues can be identified and resolved before they escalate into a crisis.
