Union NJ Heat Emergency: Your AC Can't Handle 105°F Without Help
URGENT: Heat Advisory for Union Township Through Tuesday 8 PM
Heat index values reaching 105°F are causing AC failures across Union. If your system is struggling, call us immediately: (908) 249-9701
As Union Township faces its most extreme heat wave of summer 2025, with the heat index soaring to a dangerous 105°F, air conditioning systems throughout Morris Avenue, Route 22, and residential neighborhoods are being pushed beyond their limits. Here's what every Union homeowner needs to know to protect their AC system—and their family—during this heat emergency.
Why This Heat Wave Is Different for Union Residents
The National Weather Service has issued an extreme heat advisory for Union County lasting through Tuesday evening, with actual temperatures reaching 95°F and "feels like" temperatures hitting 105°F. Combined with poor air quality warnings, this creates a perfect storm for AC system failures.
"We've already responded to 47 emergency AC calls in Union since Monday morning," says our senior technician. "Systems that were marginal are now completely failing under this extreme load."
Union Neighborhoods Most at Risk
High-Risk Areas:
- •Connecticut Farms: Older homes with undersized AC units
- •Five Points: Dense housing with poor ventilation
- •Morris Avenue businesses: Commercial units running 24/7
- •Battle Hill: Hilltop exposure to direct sun
Warning Signs Your AC Is About to Fail
During extreme heat, watch for these critical warning signs:
- 1. Constant Running Without Cooling: If your AC runs continuously but the temperature won't drop below 78-80°F, it's overwhelmed.
- 2. Ice on the Unit: Paradoxically, extreme heat can cause your AC to freeze up due to overwork and poor airflow.
- 3. Unusual Noises: Grinding, squealing, or banging sounds indicate components failing under stress.
- 4. Circuit Breaker Tripping: Overheating units draw excessive power, tripping breakers repeatedly.
- 5. Warm Air from Vents: The ultimate sign of compressor failure or refrigerant issues.
Emergency AC Survival Guide for Union Residents
Immediate Actions to Take:
1. Raise Your Thermostat: Set it to 78°F or higher. Every degree lower increases strain by 3-5%.
2. Close Blinds and Curtains: Block direct sunlight, especially on south and west-facing windows.
3. Check Your Filter NOW: A clogged filter during extreme heat can cause immediate system failure.
4. Clear Your Outdoor Unit: Remove any debris, leaves, or vegetation within 2 feet of the unit.
5. Use Fans Strategically: Ceiling fans help circulate cool air, reducing AC workload.
Why Union's Infrastructure Makes It Worse
Union Township's aging electrical grid, already stressed from recent flooding damage, struggles under the massive power demand. Areas near Route 22 and older sections of Morris Avenue experience voltage fluctuations that can damage AC compressors.
Additionally, Union's hard water creates scale buildup in AC coils, reducing efficiency by up to 30%. During extreme heat, this efficiency loss can mean the difference between a working system and complete failure.
Health Risks: When AC Failure Becomes Dangerous
Seek Immediate Help If:
- • Indoor temperature exceeds 85°F
- • Family members show signs of heat exhaustion
- • You have elderly residents or infants
- • Anyone has respiratory conditions (air quality is also poor)
- • Medications require temperature control
