Why Is My Electric Bill So High? Common Causes & How to Lower It

Published December 2025 | By Thomas Electric

For many New Jersey and Pennsylvania homeowners, a sudden spike in electric bills can be alarming. You might be wondering, "Why is my electric bill so high?" The answer to this question often lies in outdated systems, inefficient usage, and regional factors. Our licensed electricians at Thomas Electric want you to know what can cause electric bill spikes and how you can bring down your costs. We can help you make smart changes that reduce energy waste and lower your monthly expenses.

Outdated Appliances Are Energy Hogs

Although old appliances may still function, they often lack modern energy-saving technology. Refrigerators, washing machines, and dryers older than 10 to 15 years consume far more energy than new models. These older appliances can cause energy spikes, even during normal usage.

Upgrading to new ENERGY STAR-certified appliances can significantly affect your energy usage. New installations can reduce energy waste and lower your costs substantially over time.

HVAC Inefficiencies Cause Skyrocketing Bills

Heating and cooling systems are the biggest contributors to rising electricity costs. In New Jersey and Pennsylvania, summers are hot and humid, while winters bring bitter cold. These extreme temperature swings force your HVAC system to work overtime to meet demand.

The costs will rise even further if your heating and cooling system is outdated or poorly maintained. An underperforming AC, a struggling furnace, clogged filters, and leaky ductwork can all contribute to rising costs.

Key HVAC Facts:

  • Schedule regular maintenance or replace poorly performing HVAC systems
  • According to the EPA, installing an ENERGY STAR-certified HVAC system can save 20% to 40% on heating and cooling costs
  • Change air filters every 1-3 months for optimal efficiency

Are There Phantoms in Your Home?

No, we aren't talking about ghosts! You likely have many devices that continue to draw small amounts of power even when not in use. This is known as phantom energy or standby power. Phone chargers, televisions, gaming consoles, coffee makers, and desktop computers are common examples.

Although they do not draw a lot of power individually, phantom energy can add up over time. It helps to use smart power strips or unplug electronics and small appliances when not in use.

Common Energy Vampires:

  • Cable boxes and DVRs (use 20-30 watts even when "off")
  • Gaming consoles in standby mode
  • Computer monitors and desktop computers
  • Phone and laptop chargers left plugged in
  • Smart home devices and voice assistants

Poor Insulation and Air Leaks Might Be to Blame

Homes with inadequate insulation, drafty windows, and other air leaks force HVAC systems to work harder than necessary. In the winter, heat escapes through windows, attics, and walls. In the summer, cool air leaks out, and heat enters. The constant battle to keep temperatures comfortable leads to energy spikes.

The Power of a Home Energy Audit

If your electric bill continues to rise despite your best efforts to curb wasted energy, you may need to schedule a home energy audit. These detailed inspections involve checking for appliance performance, air leaks, and system inefficiencies. An energy audit provides a complete picture of your home's energy consumption and areas for improvement.

Following a home energy audit, a professional can recommend cost-effective solutions. Whether you need minor fixes or major system and appliance overhauls, the goal is increased electrical efficiency.

Electrical Inspections Can Pinpoint Problems

Sometimes, high electric bills are due to the wiring within your home. Issues like faulty or outdated wiring, overloaded circuits, and damaged electrical panels can all cause high electric bills.
