We’ve been in a lot of homes across the Denver Metro area—Aurora, Arvada, Littleton, and beyond—and one thing we keep hearing from our neighbors is, “Why is my energy bill so high lately?”

If you’ve asked yourself the same thing, we get it. As a family-run business, we know what it’s like to try to keep your home comfortable without blowing your budget, especially in Colorado, where it can snow one day and hit 80 degrees the next. We’ve lived it, and we’ve helped hundreds of families navigate it, too.

Let’s talk about a few things that might be driving up those bills—and what you can do about them.

Your HVAC System Might Be Working Overtime

Your heating and cooling system is the biggest energy user in most homes, and it gets pushed hard in Colorado’s wild weather. One week, you’re turning on the furnace. The next, you’re running the A/C. That constant swing can wear your system out fast.

If your air filters are dirty or your vents are blocked, your HVAC has to work a lot harder to move air. That means higher energy use and higher costs. The same goes for older systems. If your furnace or A/C is 10–15 years old (or older), it’s probably not as efficient as it once was.

And don’t underestimate how much your thermostat settings matter. Constantly adjusting the temperature can make your system run longer than necessary. We recommend setting it and letting it ride—or investing in a smart thermostat that can help you manage your usage more efficiently.

From our family to yours: Seasonal maintenance is one of the best things you can do. It’s like a wellness check-up for your HVAC system—and it can go a long way in keeping things running smoothly.

Leaky Plumbing Can Quietly Drain Energy

We often think of plumbing issues as water problems, but they can also affect your energy bill, especially when hot water is involved.

A faucet that drips all day or a pipe with a small leak might not seem like a big deal, but if it’s leaking hot water, your water heater is constantly working to keep up. That adds up, especially during the colder months when everything’s working harder already.

Older water heaters can also become energy hogs. If yours is past its prime, it might be time to consider a more efficient model. And keep an eye (and ear) out for toilets that never stop running. They can waste hundreds of gallons a day.

Simple tip: Insulate your hot water pipes—especially in unfinished basements or crawl spaces. It’s an easy fix that can help you keep more heat in and save on energy.

Electrical Systems: The Hidden Culprit

You might not notice it, but your electrical system could be driving up your bill, too. A lot of older homes around here still have outdated wiring or electrical panels. Not only can that be unsafe, but it can also mean your home isn’t using power as efficiently as it could be.

Another big one? Phantom loads. That’s when electronics—TVs, chargers, game consoles—use power even when they’re turned off. They’re sneaky like that.

And if you haven’t switched over to LED bulbs yet, you’re likely spending way more on lighting than you need to.

Pro tip from the Great Guys crew: Smart power strips are a great way to cut down on wasted electricity. And we’re always happy to come out and do an energy checkup to see where your system might be costing you.

Let’s Not Forget Colorado’s Crazy Weather

One of the best (and sometimes most challenging) parts about living here is the weather. It keeps us on our toes—and it keeps our homes working hard.

In the winter, your furnace has to battle freezing temps. In the summer, your AC runs longer just to keep up with the dry heat. If anything in your system is struggling—whether it’s a cracked seal, a dirty filter, or outdated equipment—it’ll show up on your bill fast.

That’s why we always tell folks: spring and fall are the best times to get ahead of the extremes. A quick tune-up now can save you a big headache (and a big bill) later.
