Summer Preventative Maintenance

As temperatures climb, so does the pressure on commercial HVAC systems. For facility managers, summer is not just another season, it’s a stress test. Cooling systems must work harder and longer, often around the clock, to maintain comfortable, compliant, and safe indoor environments. But without proper preventative maintenance, even high-performing equipment can falter under the heat. In this blog, we explore the benefits of preventative maintenance and the consequences of avoiding it.

The consequences of neglecting summer preparation can be costly: unexpected breakdowns, disrupted business operations, frustrated tenants or customers, and skyrocketing repair bills. Fortunately, these problems are largely avoidable.

By investing in summer-specific preventative maintenance, facility managers can dramatically reduce downtime, increase energy efficiency, and extend the life of their HVAC systems—all while maintaining peace of mind during the most demanding months of the year.

Peak summer months create the highest demand for cooling systems. If equipment is not properly serviced beforehand, it’s more likely to fail when it’s needed most. Emergency service calls during the summer often come with longer response times, higher costs, and potential business disruption.

Proactively addressing minor issues—like worn belts, low refrigerant, or clogged filters—can prevent major system failures when response time is critical. Scheduling maintenance before summer ensures HVAC systems are fully operational and ready to perform under pressure.

Summer heat will expose vulnerabilities in any HVAC system. Preventative maintenance helps avoid issues such as:

· Compressor overloads due to dirty coils or poor airflow

· Refrigerant leaks that reduce cooling efficiency

· Thermostat malfunctions leading to temperature swings or system cycling

· Clogged filters that restrict airflow and strain equipment

These problems not only compromise comfort but also drive up energy costs and increase the likelihood of complete system failure.

A comprehensive summer maintenance visit should cover:

· Inspection and cleaning of condenser and evaporator coils

· Air filter replacement to improve airflow and indoor air quality

· Checking refrigerant charge and testing for leaks

· Inspecting electrical connections, belts, and motors

· Testing system controls and thermostat calibration

This checklist ensures the system is optimized for energy-efficient, reliable performance throughout the season. According to the U.S. Environmental Protection Agency, well-maintained systems operate more efficiently, which can lead to 15–20% lower energy usage during peak cooling months. They also tend to last up to 30% longer than neglected units. Most importantly, preventative maintenance reduces the risk of surprise breakdowns, helping avoid costly emergency service calls and lost productivity.

Summer can be your HVAC system’s toughest test—or just another season—with the right preparation. Preventative maintenance ensures your equipment is ready for the challenge, protecting your bottom line and ensuring comfort across all your properties.
