How to Prepare Your Air Compressor for the Summer Heat

As temperatures rise, so does the strain on your compressed air system. The heat of summer can push your equipment—and your operations—to their limits. Whether you’re in a manufacturing facility, a packaging plant, or any other industrial setting, preparing your compressed air system for the summer heat is essential to prevent breakdowns, improve efficiency, and extend the life of your equipment. 

Here’s how to get your system summer-ready before temperatures soar. 

Why Summer Puts Extra Stress on Compressors 

Heat increases the workload on your compressor’s cooling systems, lubricants degrade faster, and moisture in compressed air becomes harder to manage. If not maintained, these issues can result in: 

• Overheating and shutdowns 

• Loss of efficiency 

• Excessive oil carryover 

• Poor air quality 

• Damage to downstream equipment 

The good news? Proactive maintenance and preparation can prevent these problems before they start. 

Summer Air Compressor Prep Checklist 

Use this checklist as part of your seasonal maintenance plan: 

1. Clean or Replace Air Filters and Dryers

• Dirty filters restrict airflow, forcing your compressor to work harder. 

• Replace the compressor’s cabinet filters and clean pre-filters on enclosed units. 

• Summer humidity means that you could have water all throughout your compressed air system if filters or dryers are not working properly 

2. Inspect and Clean Coolers

• The heat exchangers (air and oil coolers) must be free of dust and debris. 

• Use compressed air or a soft brush to remove buildup that can insulate and trap heat.

3. Check and Replace Lubricants

• High temps break down oil faster. Make sure the oil is clean and topped off. 

• Use OEM-recommended lubricants rated for high-temperature environments.

4. Inspect Belts and Hoses

• Heat causes rubber components to crack or loosen. 

• Look for signs of wear or swelling and replace them as needed.

5.  Ensure Proper Ventilation

• Verify that your compressor room has adequate airflow. 

• Avoid recirculating hot air and consider installing exhaust fans if needed.

6. Drain Moisture More Frequently

• Warm air holds more moisture, increasing condensate. 

• Check and clean drains and inspect your oil-water separator for proper operation. 

• Check moisture drains on tanks and piping systems, as well as dryers and filters 

• If you are manually draining your tanks or utilizing inefficient timer drains, summer is the perfect time to invest in a zero-loss drain. 

7. Monitor Temperature and Pressure Readings

• Watch for increases in discharge temperature or pressure drops, which may indicate overheating or restrictions. 

• Install remote monitoring if not already in place. 

8. Inspect Electrical Connections

• Loose or corroded connections can worsen in heat. 

• Tighten and clean terminals to prevent electrical faults. 

• Check your incoming power supply in case of potential voltage drop issues due to a high demand of the electrical grid during summer.  

9. Review Load/No-Load Cycles

• Excessive cycling may indicate a system design or control issue, which heat can exacerbate. 

• Consult with a compressed air professional. The solution could be as simple as increasing your pressure band or adding additional storage. 

10. Schedule a Preventive Maintenance Service

• Schedule a professional checkup if it’s been over six months since your last full inspection. 

• FS-Compression offers summer system tune-ups to keep your system running strong. 

Bonus Tip: Consider System Upgrades 

If your facility sees peak demand in the summer months, now might be the right time to: 

• Add a supplemental rental unit for extra capacity 

• Install a remote monitoring system to track performance and prevent downtime 

• Upgrade to a more efficient, two-stage or variable speed drive unit 

Don’t Sweat It — Stay Cool All Summer Long
