As New Jersey Summers Stretch Longer and Hotter, Your Air Conditioner is Working Overtime—Here’s What You Need to Know

New Jersey residents are experiencing something unprecedented: summers that seem to stretch endlessly, with temperatures soaring well into triple digits and heat waves becoming the new normal. The annual mean temperature in New Jersey over the last century has increased 2.9°F. In general, summers are longer and hotter. This dramatic shift isn’t just uncomfortable—it’s fundamentally changing how our air conditioning systems operate and how often they need repairs.

The Numbers Don’t Lie: New Jersey’s Extended Summer Season

On average, someone in New Jersey will experience about 35 extremely hot days in 2050. But we’re already seeing the effects today. According to a state-level analysis, by the middle of this century an estimated 70% of summers in this region are anticipated to be hotter than what we now recognize as the warmest summer on record. New Jersey has been one of the fastest warming states throughout the country, making it a hotspot for climate change impacts.

What does this mean for your home? Longer, hotter summers will exacerbate health conditions such as asthma, heat stress, and allergies, making reliable air conditioning not just a comfort issue, but a health necessity. The extended cooling season means your AC system is running for months longer than it was designed to handle just a few decades ago.

Why Your AC is Struggling More Than Ever

During recent heat waves, many New Jersey homeowners discovered a frustrating reality: Say you kept your thermostat set at 75 degrees during New Jersey’s first heat wave, but your home never got cooler than, say, 81 degrees when the outside temperature was 101 degrees. No matter how low you set your thermostat to, the inside air remained in the 80s until the outside air finally started to cool later at night.

This isn’t necessarily a sign of system failure. Reduced airflow makes it harder for your AC system to properly cool your home and often causes the system to run longer than necessary. When systems run continuously for extended periods, several issues emerge:

• When an HVAC system works harder to produce the same level of cooling, it consumes more energy.
• Dirty filters make your air conditioner work harder.
• If cold air is escaping (or hot air is sneaking in), your AC has to work overtime.

The Real Cost of Climate Change on Your HVAC System

Higher electricity rates particularly affect air-conditioning costs during New Jersey’s increasingly hot summers, making cooling a larger share of your annual HVAC expenses. The financial impact is significant: each degree you lower it below 78 can increase your cooling costs by roughly 3–5%. That adds up quickly, especially during multi-day heatwaves in Jersey.

Beyond energy costs, the extended runtime is accelerating wear and tear on HVAC systems. This pattern not only reduces comfort but also places extra strain on system components. Components that were designed to cycle on and off regularly are now running continuously for days or weeks at a time, leading to premature failures and more frequent repair needs.

When to Call for Professional Help

With New Jersey’s climate putting unprecedented demands on cooling systems, knowing when to seek professional help is crucial. Recognizing early warning signs that your air conditioner needs service can prevent unexpected breakdowns and expensive repairs later in the season. If you notice any of the following issues, it may be time to schedule professional HVAC service before temperatures climb.
