Why Is My Energy Bill Higher Than Usual?

Does your utility bill keep creeping up, even though your habits haven’t changed?

If you’re constantly wondering why your energy bill is so high, you’re not alone. Many homeowners across Tulsa and the surrounding areas are surprised by sudden spikes in their energy costs – and most don’t realize that small issues in the home can lead to big utility bills.

At ProThermal Heating and Cooling, we help homeowners track down the source of energy waste and restore both comfort and efficiency. Here’s what might be driving up your bill, and what you can do to bring it back down.

HVAC Problems That Drive Up Energy Bills

Your heating and cooling system is often the biggest energy consumer in your home. When something’s off, it has to work harder – and that effort shows up on your utility bill.

Here are some common HVAC issues that lead to high energy use:

• Dirty or clogged air filters reduce airflow and force your system to run longer to maintain comfort.
• Leaky ductwork lets your heated or cooled air escape into attics or crawl spaces before it ever reaches your living areas.
• Older or outdated HVAC systems are less efficient, often running longer than necessary just to keep up with temperature demands.
• Malfunctioning thermostats can cause your system to cycle on and off more frequently than needed, wasting energy throughout the day.

If your HVAC system hasn’t been serviced in awhile, or is over 10 years old, it could be the main reason your energy bills keep rising.

Poor Insulation Can Be Costing You

Insulation is one of the most overlooked contributors to energy efficiency, especially in older Tulsa homes. Without proper insulation in your attic, walls, or crawl spaces, it’s nearly impossible to keep your home at a steady, comfortable temperature.

When insulation is lacking, you may notice:

• Uneven temperatures between rooms
• HVAC systems running constantly
• Hot or cold spots throughout your home

In short, your heating or cooling system ends up doing all the work that insulation is supposed to help with – leading to higher energy usage and higher utility bills. Investing in insulation improvements can lower your monthly costs and extend the life of your HVAC system.

Everyday Habits That Waste Energy

It’s not just your HVAC system or insulation… Daily habits can also add up to major energy loss over time.

Do any of these sound familiar?

• Leaving lights, TVs, or electronics on when not in use
• Running the dishwasher or laundry during peak hours
• Forgetting to close doors and windows while the HVAC is running
• Ignoring small air leaks around windows, vents, or door frames

Simple changes like using appliances during off-peak times, sealing air leaks, and turning off unused electronics can make a noticeable difference. The more efficient your habits, the more your home (and energy bill) benefit.
