How Whole-Home Generators Keep Your Family Comfortable During Summer Storms

Home | Blog | Published on July 28th, 2026

Summer storms roll through Allentown with little warning and bring heavy rain, high winds, lightning, hail, and power outages that can last for hours or days. Losing electricity during extreme heat is more than an inconvenience and can directly impact your family’s comfort, safety, and health.

Our team at Jack Lehr Heating, Cooling & Electric helps homeowners prepare for unexpected outages with reliable whole-home generator solutions. Here’s why more families are making backup power part of their emergency plan.

What Happens When the Power Goes Out During a Summer Storm?

Most homeowners worry about their AC as soon as the power goes out, but an outage does more than affect the temperature in your home. Without electricity, you could also lose:

  • Refrigeration for food and medications
  • Medical devices that need power
  • Internet service
  • Sump pumps that help prevent basement flooding
  • Security systems and exterior lighting
  • Charging access to phones and essential devices

Even a brief outage can turn stressful when temperatures and humidity continue to rise inside of your home. You also increase the risk of mold and mildew growth as heat and moisture build up inside your home.

Is a Whole-Home Generator Worth It?

Yes, a whole-home generator is worth it for homeowners who want convenience, peace of mind, safety, and comfort. Unlike portable generators that need a manual setup and refueling, a whole-home generator is permanently installed outside your home and connected to your electrical system. If the power goes out, your generator starts up automatically and restores power within seconds.

A whole-home generator is also important if you travel and your power goes out. Whether you’re at work or on vacation, an automatic standby generator can keep your refrigerator running and security systems on until the power goes back on.

Will a Whole-Home Generator Run My Air Conditioner?

A whole-home generator that is the right size for your home can power your central AC system along with other essential appliances and circuits. Choosing the right generator depends on your home’s electrical needs. If you choose a generator that’s too small, it can leave you without enough power. Buying one that’s too large for your home can increase installation costs without providing additional benefits. Give our team a call and we’ll come out to make sure you get the right size to keep your AC on.

How Do I Know What Size Generator I Need?

Generator sizing isn’t based on the size of your house. Instead, it’s determined by how much electricity your home uses and which systems you want to keep operating if the power goes out. We’ll come out to evaluate your home’s electrical demand, talk through your priorities, and recommend a generator that fits your family’s needs.

Who Installs Whole-Home Generators Near Me?

Installing a whole-home generator needs licensed electrical work, fuel connections, permits, and thorough system testing. You need an experienced team to make sure your generator operates safely and automatically when you need it most.
