The Climate Crisis is Breaking Your AC: Why Nassau County Homeowners Need More Service Visits Than Ever Before

As climate change transforms Long Island’s weather patterns, Nassau County residents are facing an unprecedented challenge: their air conditioning systems are working harder, failing more often, and requiring significantly more maintenance than ever before. What was once an annual tune-up is now becoming a multi-visit necessity as extreme heat events push HVAC systems beyond their traditional limits.

The New Reality: Climate Change Hits Home

Recent research from the New York Institute of Technology studying Nassau County specifically shows that climate change is having direct impacts on building energy systems, with New Yorkers at risk of heat-related illness because summer temperatures are warming and our bodies are not used to long periods of extreme heat. Extreme heat is the deadliest weather-related hazard in the United States, and climate change is driving up its frequency and intensity, with heat-related deaths nearly doubling in recent years, rising from 1,156 in 2020 to 2,394 in 2024.

For Nassau County homeowners, this translates to a stark reality: the average household electric bill over the summer of 2025 is expected to be $178 per month, and that’s assuming your AC system can keep up with the demand.

Why Your AC System is Struggling

Rising exposure to high temperatures lifts the likelihood of AC adoption and leads to higher electricity use among households with AC, with heatwaves increasing the frequency of outages by 3.9%–4.0% and extending their duration by 7.9%–8.3%. The problem isn’t just about comfort—it’s about system survival.

Hydrofluorocarbons (HFCs) can be leaked from air conditioners during production of the unit, during installation or even from an air conditioner that is outdated and in need of maintenance. Emissions of these synthetic gases mainly occur when equipment is leaking, for example due to incorrect maintenance or disposal.

The increased strain on AC systems means components are wearing out faster, refrigerant leaks are becoming more common, and what used to be minor issues are now becoming major failures during peak demand periods.

The Maintenance Revolution: From Annual to Seasonal

Traditional wisdom suggested annual AC maintenance was sufficient, but climate change has rewritten the rules. Clean air filters, seal ducts and gaps, and invest in preventative maintenance are no longer optional—they’re survival strategies for your HVAC system.

Modern AC systems now require:

• Pre-season preparation (April-May): Deep cleaning, refrigerant level checks, and component inspections
• Mid-season maintenance (July-August): Filter changes, coil cleaning, and performance optimization during peak usage
• Post-season assessment (September-October): System evaluation and preparation for the next cooling season

Clogged air conditioner filters cause the AC to work harder pushing air through them, and regularly cleaning and replacing the filters is an easy and inexpensive way to cut your air conditioner’s energy use.

The Cost of Inaction

Delaying maintenance in this new climate reality isn’t just expensive—it’s potentially dangerous. If utilities fail to proactively manage the supply adequacy to meet the rising demand, rolling outages during extreme heat events could become more frequent, with recent major blackouts in various parts of the United States serving as stark reminders of the high societal costs of not accounting for the climate-induced demand increase.

The share of households with residential AC could grow from 27% to 41% globally, implying up to a doubling of residential cooling electricity consumption, from 1220 to 1940 terawatt-hours yearly. This massive increase in demand means your system needs to be in peak condition to compete for limited grid resources during extreme heat events.

Future-Proofing Your Comfort

If your AC system still relies on older refrigerants, servicing and repairs may become more expensive as these refrigerants become scarce, making replacing your system now a way to save from future headaches, as newer AC units are not only compliant with new regulations but also more energy-efficient.

Increasing access to air conditioning is an important health and safety solution, especially as climate projections indicate that extreme heat events will become more frequent and severe, though most air conditioning runs on electricity generated by burning fossil fuels, leading to more emissions and contributing to a dangerous feedback loop.

Taking Action Today

The maintenance frequency revolution isn’t coming—it’s here. Nassau County homeowners who adapt their maintenance schedules to this new reality will enjoy reliable cooling, lower energy bills, and peace of mind during extreme heat events.
