In Durham County, HVAC technicians are experiencing a surge in service calls as central AC units struggle and fail under persistent summer heat, highlighting a preventable crisis for many homeowners. For every degree over 95 degrees Fahrenheit, AC systems begin to struggle, according to WSMV. Increased strain on central AC units reflects widespread neglect of basic maintenance, impacting homeowners in 2026.
Extreme summer heat places immense strain on AC systems, yet many homeowners overlook the simple, proactive maintenance steps that could prevent breakdowns and ensure comfort. High humidity also forces AC units to work harder, leading to increased heat gain inside homes, WHSV reports.
Homeowners who adopt a proactive maintenance approach will likely avoid the discomfort and financial burden of emergency AC repairs, while those who delay will face increased risks during peak demand. If an air conditioning system stops working during hot weather, especially if it might be frozen, it should be turned off immediately to prevent further damage, according to WSMV. Immediate shutdown prevents further damage, a critical and often counterintuitive emergency protocol.
Essential AC Maintenance Tasks for Homeowners
- Homeowners can extend the life of their central AC units with several simple maintenance tasks. Changing air filters is a key step homeowners can take to protect their units, according to ABC11 News. Filter changes directly increase airflow within the home, enhancing system efficiency, WSMV reports.
- Beyond filters, homeowners can vacuum air intake vents and keep outdoor AC units free of obstructions. Sealing air leaks around doors and windows also helps reduce strain on the system, according to The Des Moines Register. Actions prevent units from working harder than necessary.
- However, DIY efforts alone may not suffice for older systems. An air conditioning system that is eight years or older and lacks recent maintenance requires professional service before the hottest days arrive, WSMV advises. Proactive maintenance, encompassing both regular DIY tasks and professional servicing for older units, is the most effective strategy for homeowners to ensure their AC systems perform reliably when needed most.
Why AC Units Fail in Summer Heat
The current surge in HVAC service calls in Durham County isn't solely due to extreme weather; it reflects widespread homeowner neglect of basic maintenance, according to ABC11 News. Inaction turns minor issues into costly, uncomfortable emergencies. Homeowners are effectively forcing their AC units to operate under maximum duress by not optimizing basic airflow or reducing heat infiltration, as noted by WSMV and The Des Moines Register.
Many homeowners are inadvertently accelerating the demise of their AC units. Failing to perform simple tasks like changing filters and sealing leaks forces systems to work harder against extreme heat, leading to premature failure. The combination of increasingly extreme heat and aging AC systems means that even diligent DIY maintenance often proves insufficient, WSMV reports.
Oversight is particularly critical for older units. Pre-emptive professional servicing for AC systems eight years or older is essential to prevent system failures, a step many homeowners likely overlook. Neglecting this professional check for aging units creates a false sense of security, delaying intervention when comprehensive care is required.
Balancing DIY and Professional AC Care
Simple DIY maintenance tasks offer significant benefits, as highlighted by ABC11 News and The Des Moines Register. Actions are effective and accessible for many homeowners. However, this advice must be balanced with the needs of older systems.
WSMV advises that AC systems eight years or older require professional service before the hottest days. A tension is created: homeowners might overestimate DIY protection for aging units. Relying solely on DIY fixes for these older systems can lead to a false sense of security and delayed professional intervention.
Homeowners with AC units eight years or older are playing a dangerous game by relying solely on DIY fixes, as these systems require professional pre-season checks to withstand increasingly severe heatwaves, according to WSMV and WHSV. The combination of extreme heat and aging units makes pre-emptive professional servicing critical to prevent failures. By 2026, homeowners must prioritize these checks to avoid the significant costs and discomfort associated with system breakdowns during summer, as outlined by WSMV.
