Summer 2025 has brought record-breaking heat, putting immense strain on commercial HVAC systems and challenging building managers to keep facilities cool without incurring excessive costs. <\/p>\n\n\n\n
According to The National Center for Environmental Information<\/a>, June 2025 was the seventh warmest in the agency\u2019s 131-year record. While some areas were just moderately warmed, others, including parts of the Florida Peninsula and Northeast region, were affected by \u201cmuch-above-average warmth.\u201d<\/p>\n\n\n\n To keep buildings cool during peak season, heating, ventilation, and air conditioning (HVAC) units have to work overtime<\/strong>, increasing energy consumption, cost, and risk of breakdown. <\/p>\n\n\n\n HVAC already accounts for 35 percent of energy consumption<\/a>, the largest share of a building’s total energy use, and these elevated temperatures are pushing consumption even higher.<\/p>\n\n\n\n The good news is that your facility isn\u2019t powerless against summer heat. <\/p>\n\n\n\n A proactive approach to HVAC management can significantly reduce energy use, lower costs, and ensure your systems remain reliable when you need them most.<\/p>\n\n\n\n Based on our four decades of experience<\/a>, here are five practical tips<\/strong> your business can implement to maximize efficiency and avoid breakdowns during peak season.<\/p>\n\n\n\n Think of HVAC maintenance like regular service for your car. Routine inspections and tune-ups keep systems running smoothly, help prevent catastrophic failures, and extend the life of your equipment.<\/p>\n\n\n\n Tip: Schedule preseason checks in spring and fall.<\/strong> Identifying issues before cooling or heating season ramps up gives you time to fix problems without emergency costs.<\/p>\n\n\n\n A well-maintained system runs more efficiently, uses less energy, and is far less likely to break down during a heatwave.<\/p>\n\n\n\n As Yunho Hwang of the University of Maryland explains:<\/p>\n\n\n\n \u201cIf the filter is not clean, then air flow rate will be decreased, and that means the inefficient operation of the cooling system and so on.\u201d<\/p>\n\n\n\n A preventive maintenance program ensures scheduled inspections, filter management, HVAC optimization techniques, and performance tracking\u2014all while turning unpredictable costs into a fixed, budgetable line item.<\/strong><\/p>\n\n\n\n Smart technologies like Building Automation Systems (BAS) offer precise control over your facility’s climate.<\/p>\n\n\n\n These systems introduce several benefits for commercial buildings<\/a>, including: <\/p>\n\n\n\n Tip: Use data analytics<\/strong> from your BAS to identify trends in usage, detect inefficiencies, and inform future capital planning. Data = dollars saved.<\/p>\n\n\n\n However, an off-the-shelf offering won\u2019t fully optimize your building’s unique requirements.<\/p>\n\n\n\n At Thermal Concepts, we offer customized automation solutions<\/a> that integrate with your <\/em>HVAC system, ensuring precise control, energy savings, and improved building operations.\u00a0<\/p>\n\n\n\n It may seem simple, but a clean air filter is critical to an efficient HVAC system. <\/p>\n\n\n\n Dirty, clogged filters restrict airflow, forcing the system to work harder to circulate cool air. <\/p>\n\n\n\n Tip:<\/strong> Use labeled reminders on your calendar or BAS system<\/strong> to prompt filter checks every 30-60 days depending on usage and environmental conditions.<\/p>\n\n\n\n This unnecessary strain leads to higher energy bills, reduced cooling performance, and can even cause the system to overheat and shut down. Establishing a regular schedule for checking and changing filters is a low-cost, high-impact step toward better efficiency.<\/p>\n\n\n\n In many large commercial and industrial facilities, it\u2019s common for multiple HVAC units to operate simultaneously. <\/p>\n\n\n\n However, poor or imbalanced airflow can cause these systems to run unevenly, so one unit is overloaded while the other is underutilized.<\/p>\n\n\n\n This undermines climate control outcomes and introduces excessive wear on the harder-working equipment.<\/p>\n\n\n\n Tip: Reassess airflow distribution annually, especially after office renovations or tenant turnover<\/strong>, which can affect ductwork efficiency and zone balance.<\/p>\n\n\n\n Airflow testing and equipment balancing corrects this issue by ensuring that the workload is distributed evenly, maximizing efficiency, and preventing premature equipment failure.<\/p>\n\n\n\n If your HVAC system is older, it might struggle to keep up during peak season, no matter how well you maintain it. <\/p>\n\n\n\n#1 Invest in Proactive, Preventive Maintenance<\/h2>\n\n\n\n
