Think of your home’s HVAC system like the engine in your car. When it’s not properly maintained, it burns through fuel without giving you the performance you expect. The same is true for your heating and cooling equipment; it can burn through electricity, leaving you with a shockingly high bill. But you don’t have to just accept this as a fixed cost of homeownership. By focusing on efficiency, you can get the comfort you want without the excessive expense. We’ll walk you through the key areas to address, from simple maintenance tasks to smart home upgrades that put you in control. It’s time to stop wasting energy and start taking steps to lower your power bill.
Inefficiencies in your HVAC system can raise your power bills significantly. They can also prevent the system from maintaining a comfortable temperature. However, there are numerous ways you can improve energy efficiency and save on energy costs (including signing up for your HVAC contractor’s maintenance program). Some of these methods can reduce your utility bill by as much as 20% to 40%! That adds up quite a bit over time. To lower your power bills:
Understanding Your Home’s Energy Use
Before you can effectively lower your power bill, you need to know where your energy is actually going. Think of it like a budget; you can’t find places to save if you don’t track your spending. According to the U.S. Department of Energy, reducing your home’s energy consumption not only saves you money but also contributes to greater energy security and less pollution. It’s a win-win. The biggest culprits are often hiding in plain sight, from appliances and lighting to your heating and cooling systems. By getting a clear picture of your usage patterns, you can pinpoint the exact areas where a few small changes can make a big financial difference.
Conduct a Home Energy Assessment
One of the most effective ways to understand your home’s energy profile is to get a professional home energy assessment. This is essentially a check-up for your house, where an expert identifies sources of energy loss and suggests improvements. They’ll look for things like air leaks around windows and doors, inadequate insulation, and inefficient appliances. Your HVAC system is a major focus of these assessments, as it’s typically the largest energy consumer in any home. A technician can spot inefficiencies you might miss, ensuring your system isn’t working harder than it needs to. Regular check-ups through a service maintenance program can serve a similar purpose, keeping your HVAC equipment in peak condition.
Know Your Numbers: Smart Meters and Averages
Your monthly utility bill is more than just a number to pay—it’s a report card on your home’s energy performance. Take a moment to review it each month and look for trends. Many utility companies now offer smart meters, which provide detailed data on your electricity usage throughout the day. This information is incredibly valuable for spotting “vampire loads”—electronics that draw power even when they’re turned off. By seeing exactly when your energy use spikes, you can make informed decisions, like running the dishwasher at night or finally unplugging that old TV in the guest room. This data empowers you to take control of your consumption habits.
HVAC and Home Improvements to Lower Your Power Bill
Your heating, ventilation, and air conditioning (HVAC) system is the heart of your home’s comfort, but it’s also the biggest player on your energy bill. An inefficient or poorly maintained system has to run longer and harder to keep you comfortable, sending your electricity costs soaring. One of the best ways to support your HVAC system is to ensure your home is properly insulated and sealed. Air leaks around windows, doors, and ductwork force your system to compensate for escaping conditioned air. Sealing these gaps is a simple, cost-effective fix that delivers immediate results. When your home holds onto its temperature, your HVAC unit gets a much-needed break.
Beyond sealing and insulating, focusing on the system itself is key. Regular professional maintenance ensures all components are clean and functioning correctly, which is critical for efficiency. If your system is over 10-15 years old, it might be time to consider an upgrade. Modern residential HVAC units are significantly more energy-efficient than their predecessors and can lead to substantial long-term savings. If you’re unsure whether to repair or replace your unit, a virtual consultation can be a convenient way to explore your options and find a solution that fits your home and budget.
1. Install a New HVAC System
Although not the cheapest option upfront, upgrading your HVAC system can save you a lot in energy costs over time. Older heating and cooling equipment isn’t as efficient as modern systems and loses efficiency as it ages. Newer central AC systems in North Carolina must have a minimum seasonal energy efficiency ratio (SEER) of 14.5. Also, look for high energy-efficiency ratio (EER) products with an Energy Star label. Aside from high-efficiency central HVAC systems, other alternatives can lower your power bills. These include ductless mini-splits. These eliminate inefficiencies due to duct leaks. Heat pumps are also more efficient; they are reversible, so they provide heating in winter and cooling in summer, transferring heat like a refrigerator to provide comfort. Additionally, rebates from utility companies and federal tax credits for purchasing certain high-efficiency units can save you money if you qualify for them.
2. Clean the Condensing Unit Coil
When the refrigerant passes through the condenser coil, it releases heat into the air. A coating of dirt, dust, and grime can inhibit heat transfer, reducing system efficiency. It can also prevent the system from properly heating or cooling your home and cause the unit to overheat and shut down. To clean the coil, first turn off the power to avoid a shock. You can use a commercial coil cleaner or water and mild detergent to clean AC coils. A garden hose can be used at low pressure to wash off the coil. Spray left and right, starting at the bottom, a few inches at a time, to wash away dirt and debris. A professional can also clean the coils during annual maintenance and take additional steps to improve efficiency, such as straightening fins or sealing a leaky coil.
3. Change the Air Filter Regularly
Just by changing the filter regularly, you can reduce your HVAC unit’s power use by up to 15%.1 Replace the filter as recommended by the equipment manufacturer. Generally, AC filters should be changed every two or three months (more frequently if your home is dusty or you have pets that shed often). A clogged filter restricts airflow, which can lead to uneven cooling. The system will run longer to compensate, not only leaving parts of your home overly cooled or overly heated but also increasing energy usage. A dirty filter strains the system as well, so it will need to be repaired or replaced more frequently.
4. Choose a Smart Thermostat
Traditional thermostats don’t help much in terms of saving energy. But a programmable or smart model can. The ability to program a thermostat lets you set the temperature at an appropriate level during certain hours, like when you’re at work. A smart thermostat takes it further by allowing you to monitor and adjust it remotely from your smartphone. Also, set the temperature 7℉ to 10℉ higher in summer or lower in winter to save energy. Consider the thermostat’s location as well. It should be installed out of direct sunlight, on an interior wall, and not near any drafts.
5. Weatherize Your Home
Taking various steps around your home can help your HVAC system run more efficiently. These include:
- Seal Air Leaks: Duct leaks waste a great deal of energy, so they should be sealed with aluminum tape, mastic sealant, or via professional methods. Gaps and cracks in walls, around doors, and in window frames can cause air loss; fortunately, these can be easily caulked to make your home more airtight.
- Improve Insulation: Uninsulated garages, basements, and attics should be insulated to tighten your building’s envelope. If you have old or insufficient insulation, install higher R-value materials. It’s best to hire a professional to determine if you need to add insulation in certain areas or if your entire home should be reinsulated.
- Get In the Shade: Planting more trees and shrubs outside your home can block the warming effects of sunlight. Generally, plant taller trees on the south side, where the sun’s rays are higher. Lower trees on the east and west sides block the lower morning and afternoon sun. Also, consider covering windows with solar screens, reflective metalized films, and window treatments like curtains and blinds.
Use Weather Stripping and Window Film
Going a step further than caulk, weather stripping is a fantastic way to seal the moving parts of your home, like doors and windows. Think about all the tiny gaps around the edges of your front door—they might seem small, but together they can be like leaving a window open all year round. Applying weather stripping creates a tight seal that stops conditioned air from escaping and outdoor air from sneaking in. This simple fix helps your HVAC system maintain a consistent temperature without constantly running to keep up with air leaks. It’s an inexpensive project you can tackle over a weekend, and it supports the hard work your heating and cooling system does every day.
For windows that get blasted by the sun, applying a special film can make a huge difference in your home’s comfort and energy use. Window film is designed to block a significant amount of the sun’s heat and harmful UV rays from entering your home, all without sacrificing your natural light or view. During hot North Carolina summers, this means your rooms stay cooler, giving your air conditioner a much-needed break. According to energy experts, managing this solar heat gain is a key strategy to lower your electric bill. When combined with a regular maintenance program, these small home improvements ensure your entire system operates at its best.
6. Install a Ceiling Fan
Running a ceiling fan can allow you to raise the thermostat by about 4℉ and maintain the same comfort level. The fan should run counterclockwise in summer and clockwise in winter. Windows near the fan should be kept closed. Ceiling fans help improve air circulation and help evaporate sweat from your skin, increasing the effect of evaporative cooling.
7. Schedule an Annual HVAC Tune-Up
One of the most important ways to care for your HVAC system is an annual tune-up. A trained technician will:
- Clean major components
- Lubricate moving parts
- Tighten belts, loose bolts, and electrical connections
- Inspect the blower motor
- Measure coolant levels and pressure
- Inspect the drain line
- Check limit switches and other safety features
Changing the filter and calibrating the thermostat help improve efficiency too and can contribute to lower energy bills. Your HVAC system should be maintained at least once a year (twice a year for heat pumps).
Everyday Habits That Make a Difference

It’s about working smarter, not harder, to reduce consumption without sacrificing comfort. From the way you do laundry to how you light your living room, these simple adjustments can collectively lower your energy usage and put you in control of your monthly expenses.
Reduce Appliance and Electronic Energy Use
Your appliances and electronics are some of the biggest energy consumers in your home. While you need them for modern life, how and when you use them matters. Many devices continue to draw power even when they’re turned off, a phenomenon known as a “vampire load.” Being mindful of this phantom power drain and making strategic choices about your daily chores can lead to noticeable reductions in your electricity bill. It’s all about understanding where your energy is going and finding simple ways to cut back without any inconvenience.
Tackle “Vampire Loads” from Electronics
Many of your electronics use a small amount of power even when they’re turned off but still plugged in. Think about your TV, computer, game consoles, and phone chargers. This “vampire load” can account for up to 10% of your home’s energy use. An easy fix is to plug these devices into a power strip and simply flip the switch off when you’re done using them. For individual items like chargers, get into the habit of unplugging them from the wall once your device is fully charged.
Be Strategic with Laundry and Dishes
You can save energy by changing a few simple laundry and dishwashing habits. Always try to run your dishwasher and washing machine with full loads to make the most of the water and energy used. When using the dishwasher, select the normal cycle instead of heavy-duty and use the air-dry feature to avoid the energy-intensive heating element. For laundry, washing your clothes in cold water is just as effective for most loads and saves a significant amount of energy by not having to heat the water.
Choose Energy-Efficient Appliances
When it’s time to replace an old appliance, make energy efficiency a top priority. Look for products with the ENERGY STAR label, which are certified to use less energy than standard models. This applies to everything from your refrigerator and dishwasher to your HVAC system. While an energy-efficient model might have a slightly higher upfront cost, the long-term savings on your utility bills often make it a financially smart decision that pays for itself over time.
Lower Your Water Heating Costs
Heating water is one of the most energy-intensive processes in any home, often second only to heating and cooling. Reducing your hot water consumption is a direct way to lower your power bill. Simple changes, like taking shorter showers, can make a real difference. Sometimes called “Navy showers,” this means turning off the water while you lather up. You can also lower the thermostat on your water heater to 120°F; most are set higher by default, but this temperature is sufficient for most households and can reduce water heating costs by up to 10%.
Adjust Your Lighting and Personal Comfort
How you light and live in your space also impacts your energy bill. Instead of flipping on a switch, open your blinds and curtains during the day to let in natural sunlight. When you do need artificial light, make sure you’re using energy-efficient LED bulbs, which use at least 75% less energy and last 25 times longer than incandescent lighting. For personal comfort, try dressing in layers or using a cozy blanket during cooler months before you decide to turn up the heat. These small adjustments help you rely less on your HVAC system and more on simple, cost-free solutions.
In some states, the energy market is deregulated, which means you can choose your electricity supplier instead of being locked into the local utility company. This competition can lead to better prices and different plan options. Check with your state’s public utility commission to see if you have a choice of suppliers in your area. If you do, take some time to compare the rates and terms offered by different companies. You might find a fixed-rate plan that offers more stability or a provider that specializes in renewable energy sources.
Choose a Billing Plan That Fits Your Lifestyle
Many utility companies offer different types of billing plans that can help you save money if they match your usage patterns. For example, a “time-of-use” plan charges different rates depending on the time of day. With this type of plan, you can save money by running large appliances like your dishwasher, washing machine, or dryer during “off-peak” hours when electricity is cheaper, typically overnight. Other options might include budget billing, which averages your costs for a predictable monthly payment. Contact your utility provider to ask what plans are available and see if one is a better fit for you.
