Summer in Colorado Springs is hard to beat. Long sunny days, cool mountain evenings, and plenty of time outdoors make it one of the best seasons of the year. Unfortunately, summer also brings something most homeowners don’t enjoy: higher utility bills.
If you’ve been wondering how to save money on utilities, you’re not alone. Every summer, our technicians hear from homeowners who are surprised by how much their cooling costs have increased. In many cases, the problem isn’t that the air conditioner is failing. It’s simply working harder than it needs to because of small issues around the home.
The good news is that lowering your energy bills doesn’t usually require major renovations or sacrificing comfort. A few smart habits, regular HVAC maintenance, and understanding how your home handles Colorado’s unique climate can make a noticeable difference.
At Falling Star Heating & Cooling, we’ve helped homeowners throughout Colorado Springs and the surrounding Pikes Peak region improve comfort while keeping energy costs under control. Here are some of the most effective ways to reduce your summer utility bills.
Key Takeaways for Lowering Utility Bills
- Take advantage of Colorado Springs’ cool evenings by naturally cooling your home overnight.
- Keep your thermostat at energy-efficient settings and consider upgrading to a smart thermostat.
- Schedule annual AC maintenance before summer temperatures peak.
- Seal air leaks and improve insulation to keep cool air inside.
- Run heat-producing appliances during off-peak hours whenever possible.
- Know when an aging HVAC system is costing more to operate than it’s worth.
1. Work With Colorado’s Climate Instead of Fighting It
One of the biggest advantages Colorado homeowners have is something people in many other states wish they had: cool summer nights.
Even after a warm afternoon, temperatures often drop enough to naturally cool your home. Instead of relying on your air conditioner around the clock, take advantage of those overnight conditions.
Try opening your windows after sunset or early in the morning before outdoor temperatures climb. Once the sun begins warming your home, close the windows and shut blinds or curtains, especially on south-facing and west-facing windows that receive the strongest afternoon sunlight.
This simple routine helps trap cooler air inside and reduces how long your air conditioner needs to run throughout the day.
Many homeowners are surprised by how much this habit alone can help lower monthly cooling costs.
2. Set Your Thermostat for Comfort and Savings
Your thermostat has a bigger impact on your utility bill than almost anything else in your home.
It’s tempting to lower the temperature when you come inside from a hot afternoon, but setting your thermostat to 68 degrees won’t cool your home any faster than setting it to 78. It simply tells your system to run longer until it reaches that temperature.
For most homes, the U.S. Department of Energy recommends keeping the thermostat around 78 degrees while you’re home during the summer. If you’ll be away for several hours, raising the temperature by just a few degrees can significantly reduce energy use without making your home uncomfortable.
Is a Smart Thermostat Worth It?
For many homeowners, yes.
A smart thermostat automatically adjusts temperatures based on your schedule instead of cooling an empty house all day. Some models even learn your daily routine, provide energy reports, and send maintenance reminders.
We’ve installed smart thermostats for many Colorado Springs families who wanted a simple way to save money without constantly adjusting the temperature themselves.
While every home is different, homeowners often notice lower cooling costs simply because their HVAC system isn’t running when nobody is home.
3. Keep Your Air Conditioner Running Efficiently
Your air conditioner works hard during the hottest weeks of summer. Like any piece of equipment, it performs best when it’s clean, properly adjusted, and regularly maintained.
One of the most common issues we see during summer service calls is something surprisingly simple: a clogged air filter.
When the filter becomes packed with dust, pet hair, and debris, airflow slows down. Your system has to run longer to cool the same amount of space, which increases both the wear on the equipment and your monthly electric bill.
Fortunately, replacing your air filter is one of the easiest maintenance tasks you can do yourself.
Most homeowners should check their filter every month and replace it every one to three months, depending on factors such as pets, allergies, recent remodeling projects, and how often the system runs.
While you’re outside, take a look at your outdoor condenser unit as well. Leaves, weeds, grass clippings, and even children’s toys can restrict airflow around the equipment. Giving the unit a few feet of clear space helps it release heat more efficiently and keeps your AC operating at its best.
4. Seal Air Leaks Before Your AC Pays the Price
If your home has air leaks, your air conditioner is constantly trying to cool the outdoors. Even a high-efficiency system can’t keep up if cool air is escaping through gaps around doors, windows, attic hatches, or ductwork.
Many homeowners notice signs of air leaks without realizing what’s causing them. Maybe one room always feels warmer than the rest of the house, or your AC seems to run almost nonstop during the afternoon. These are often symptoms of conditioned air escaping and hot outdoor air sneaking inside.
Walk through your home and look for:
- Drafts around windows and exterior doors
- Worn weatherstripping
- Gaps around plumbing or electrical penetrations
- Poor attic insulation
- Hot spots near exterior walls
Improving your home’s insulation and sealing leaks helps your HVAC system maintain a consistent temperature with less effort. Not only can this help lower utility bills, but it can also make every room in your home feel more comfortable.
5. Shift Energy Use to Cooler Times of Day
Your air conditioner isn’t the only appliance affecting your electric bill.
Dishwashers, clothes dryers, ovens, and even some electronics generate heat that makes your AC work harder. Running several of these appliances during the hottest part of the afternoon can noticeably increase your energy use.
If your electric plan includes time-of-use pricing, you may also pay higher rates during peak demand hours.
Whenever possible:
- Run the dishwasher after dinner or early in the morning.
- Wash and dry laundry during cooler parts of the day.
- Grill outside instead of using the oven on especially hot afternoons.
- Turn off lights and electronics that aren’t being used.
These small adjustments may seem minor, but together they can have a meaningful impact over the course of an entire summer.
6. Use Ceiling Fans to Help Your AC, Not Replace It
One of the easiest ways to save money on your AC bill is by making the cool air you already have feel even cooler.
Ceiling fans create a wind chill effect that helps your body feel more comfortable without actually lowering the room’s temperature. Because of this, many homeowners can comfortably raise the thermostat by two or three degrees while maintaining the same level of comfort.
During the summer, make sure your ceiling fans rotate counterclockwise. This pushes air downward and creates better circulation throughout the room.
Just remember to turn fans off when you leave the room. Fans cool people, not spaces, so leaving them running in an empty room only wastes electricity.
7. Don’t Skip Annual Air Conditioner Maintenance
Think of annual AC maintenance like changing the oil in your vehicle. It may seem easy to postpone, but regular service helps prevent much bigger problems down the road.
During a professional maintenance visit, an HVAC technician can:
- Check refrigerant levels
- Clean evaporator and condenser coils
- Inspect electrical connections
- Test system performance
- Measure airflow
- Identify worn parts before they fail
- Confirm your thermostat is operating correctly
These inspections help your system operate at peak efficiency while reducing the likelihood of costly breakdowns during Colorado Springs’ hottest days.
We’ve visited many homes where a simple maintenance appointment could have prevented an expensive repair later in the season. Catching small issues early is almost always less expensive than waiting until your AC stops working on a 90-degree afternoon.
8. Your Older Air Conditioner Could Be Costing You More
Sometimes the biggest reason for high utility bills isn’t your habits; it’s your equipment.
If your air conditioner is more than 12 to 15 years old, it may be using considerably more electricity than today’s high-efficiency models. Even if it’s still running, age naturally reduces efficiency as components wear down.
That doesn’t mean every older system should be replaced. Many continue operating reliably with proper maintenance.
However, replacement may be worth considering if you notice:
- Frequent repairs
- Rising monthly energy bills
- Uneven temperatures throughout your home
- Excessive noise
- Poor humidity control
- Difficulty keeping your home comfortable
Modern air conditioners use variable-speed technology that allows them to adjust cooling output instead of constantly cycling on and off. This provides steadier indoor temperatures, quieter operation, and lower energy consumption.
For many Colorado Springs homeowners, the long-term savings on energy and repairs can offset much of the investment over time.
Repair or Replace?
| If this sounds like your system… | Repair may make sense | Replacement may be the better investment |
| Less than 10 years old | ✓ | |
| Minor repair needed | ✓ | |
| Well maintained | ✓ | |
| Frequent breakdowns | ✓ | |
| 12 to 15+ years old | ✓ | |
| Utility bills keep increasing | ✓ | |
| Major component failure | ✓ |
Every home is different, which is why an honest evaluation matters. At Falling Star Heating & Cooling, we believe in recommending only the services homeowners truly need. Sometimes that’s a simple repair. Other times, replacing an aging system is the more cost-effective option over the long run.
9. Know When It’s Time to Call a Professional
There are plenty of steps homeowners can take on their own to improve energy efficiency, including changing filters, adjusting thermostat settings, and sealing obvious air leaks.
But some issues require specialized equipment and training.
Schedule an HVAC inspection if you notice:
- Your AC runs constantly without reaching the thermostat setting.
- Some rooms stay much warmer than others.
- Your utility bills suddenly increase with no obvious explanation.
- Ice forms on refrigerant lines.
- The system makes unusual noises or produces strange odors.
- Airflow from your vents feels weak.
These symptoms often point to problems that won’t improve on their own. Addressing them early can prevent larger repairs and help restore your system’s efficiency before energy costs climb even higher.

FAQs About Air Conditioning Units and Energy Costs
How can I save money on my AC bill during the summer?
You can lower your cooling costs by combining smart thermostat settings, regular maintenance, and simple energy-saving habits. Your air conditioner runs more efficiently when filters are clean, airflow is unrestricted, and your home is properly sealed against air leaks. Scheduling annual maintenance and making small adjustments throughout the season can noticeably reduce your monthly utility bills.
What temperature should I set my thermostat to in the summer?
For most homes, 78 degrees is a good balance between comfort and energy efficiency while you’re home. Raising the temperature a few degrees when you’re away helps your air conditioner run less often without allowing your home to become excessively hot. A smart thermostat can automate these adjustments and help reduce unnecessary energy use.
Does changing my air filter really lower my energy bill?
Yes, replacing a dirty air filter can improve airflow and reduce strain on your HVAC system. When airflow is restricted, your air conditioner has to work harder and run longer to cool your home. Checking your filter every month and replacing it as needed is one of the easiest ways to improve efficiency.
Is it better to leave my AC running all day or turn it off when I leave?
It is usually better to raise your thermostat a few degrees rather than turn the system off completely. Allowing your home to become extremely hot can make your air conditioner work harder when you return. A programmable or smart thermostat can automatically adjust temperatures based on your schedule to maximize both comfort and savings.
How do I know if my air conditioner is wasting energy?
Your system may be operating inefficiently if it runs constantly, struggles to keep your home cool, or causes your utility bills to increase unexpectedly. Uneven temperatures, weak airflow, unusual noises, and frequent repairs are also common signs that something isn’t working as it should. A professional inspection can identify the cause and recommend the most cost-effective solution.
When should I replace my air conditioner instead of repairing it?
Replacement is often worth considering if your system is more than 12 to 15 years old, requires frequent repairs, or no longer cools your home efficiently. Modern air conditioners use significantly less energy and often provide more consistent comfort than older equipment. A trusted HVAC professional can help you compare repair costs with the long-term savings of installing a newer system.
