What to Do During a Power Outage in a Heatwave: HVAC Tips for Suffolk County Homeowners
A sudden power outage in the middle of a Suffolk County heatwave can make your home feel unbearable fast. Not only is it uncomfortable, but it can also be dangerous — especially for children, seniors, and those with health conditions.
Knowing what to do in the first few minutes of a power outage can help protect your HVAC system and keep your family safe. Here’s what our experts recommend if your cooling system shuts down during a blackout.
Turn Off Your HVAC System Immediately
As soon as the power goes out, turn off your air conditioner at the thermostat and breaker. This protects the unit from potential damage caused by a power surge when electricity is restored.
Keep Windows and Doors Closed
It might be tempting to open windows, but keeping them closed helps trap cooler indoor air for longer. Block direct sunlight with curtains or shades to prevent indoor temps from climbing too quickly.
Use Portable, Battery-Powered Fans
Battery-operated or rechargeable fans can provide temporary relief. Combine with damp washcloths on your neck or wrists for additional cooling.
Stay Hydrated and Seek Out Cooler Spaces
Drink plenty of water and avoid heat-producing activities. If you have a basement, it may be cooler than upper floors. Avoid using the oven or stove top.
Unplug Appliances to Prevent Power Surge Damage
When the power comes back on, a surge can damage electronics — including your HVAC system. Keep your system and large appliances unplugged until the power stabilizes.
Wait Before Restarting Your AC
Once power returns, wait at least 5–10 minutes before turning your AC back on. This allows time for electrical flow to normalize and protects your compressor.
Invest in a Whole-Home Surge Protector or Backup Generator
Surge protectors can save your HVAC equipment from serious damage. A backup generator can keep critical systems, including your AC, running when the power goes out.

When the heat and humidity rise in Suffolk County, many homeowners ask the same question: Should I leave my air conditioner running all day?
The answer depends on your cooling system, your home’s insulation, and how efficiently your HVAC is set up. In this post, we’ll break down the pros, cons, and smart strategies for using your AC during long summer days.
Pros of Running Your AC All Day
Consistent Comfort: Your home stays at a steady, comfortable temperature all day long, especially during heatwaves.
Humidity Control: Continuous operation helps maintain ideal humidity levels, which is especially important in Suffolk County’s muggy summers.
Avoiding the Rush: Some systems use less energy maintaining a steady temp than powering on and off multiple times.
Cons of Running Your AC All Day
Higher Energy Bills: If your system isn’t energy-efficient or your home isn’t well-sealed, running the AC nonstop can be costly.
System Strain: Constant operation can wear out your unit faster, especially if it’s not sized correctly or regularly maintained.
Cooling Unused Rooms: Without zoning or smart thermostats, you may be cooling empty spaces unnecessarily.
When It Makes Sense to Run AC Continuously
- You work from home or are home all day
- You have pets or family members sensitive to heat
- Your system is high-efficiency and properly maintained
- Your home has good insulation and sealed ductwork
When to Use a Timed or Automated Cooling Schedule
For many homeowners, the best approach is not all day, but rather strategic scheduling:
- Use a programmable or smart thermostat
- Raise the temp when you're not home
- Lower it before you return
- Use ceiling fans to help distribute cool air and feel cooler at a higher temp
Smart Thermostat Tips for Suffolk County Homes
- Set cooling to 78°F when home, 85°F when away
