When temperatures soar into the 90s and the humidity climbs, your air conditioner works harder than almost any other time of the year. During recent heat advisories across the Northeast, "feels like" temperatures approached 100°F, putting additional strain on home cooling systems. Many Long Island homeowners noticed the same thing: their air conditioner was running all day, but the house still didn't feel cool.
If that's happening in your home, you're not alone.

Is It Normal for My AC to Run Constantly During a Heat Wave?
Yes—to a point.
During extreme heat, your air conditioner may run for longer periods because it's trying to keep up with outdoor temperatures. However, if your system:
- Never shuts off
- Can't get your home below 75-80°F
- Is blowing warm air
- Has weak airflow
- Is making unusual noises
- Has higher-than-normal energy bills
…it may be a sign that your system needs attention.
Why Your AC Struggles During a Heat Wave
1. Dirty Air Filters
A clogged filter restricts airflow, making your system work harder and cool less effectively.
Quick Tip: Check your air filter every 1-3 months, especially during the summer.
2. Lack of Maintenance
Dust, debris, and worn components can reduce efficiency and cause breakdowns when your system is under the most stress.
3. Refrigerant Issues
Low refrigerant levels can prevent your system from removing heat properly, resulting in warm air or longer run times.
4. Dirty Outdoor Condenser Unit
Your outdoor unit needs adequate airflow to release heat. Grass clippings, dirt, and debris can reduce its performance.
5. Aging Equipment
If your air conditioner is 10-15 years old, it may struggle to keep up with prolonged periods of extreme heat.

What You Can Do Right Now
Before scheduling service, try these simple steps:
✓ Replace your air filter.
✓ Make sure all supply vents are open and unobstructed.
✓ Remove leaves and debris around your outdoor unit.
✓ Keep blinds and curtains closed during the hottest parts of the day.
✓ Avoid using heat-producing appliances like ovens and dryers during peak afternoon temperatures.
When to Call a Professional
If your AC is running constantly and your home still feels uncomfortable, don't ignore it. Heat waves often expose existing issues that may have gone unnoticed during milder weather.
Addressing small problems early can help prevent:
- Complete system breakdowns
- Higher repair costs
- Increased energy bills
- Uncomfortable indoor temperatures during the hottest days of the summer
