How to Make Your Air Conditioner More Efficient
When summer temperatures climb in Des Moines, homeowners rely heavily on their cooling systems. But a hardworking AC doesn’t have to mean skyrocketing energy bills. If you've ever asked yourself, “how to make your air conditioner more efficient,” you're not alone. Many people don’t realize how much energy (and money) is lost when AC units are neglected or used improperly.
This blog will walk you through simple, effective ways to boost your AC’s performance, cut down on energy costs, and extend the life of your system. Whether you're looking for DIY solutions or professional guidance from City Wide Heating and Air Conditioning, you’ll find everything you need to get started right here.
Start with a Clean Filter
If you're wondering how to make your air conditioner more efficient, one of the easiest steps is checking the air filter. A dirty or clogged filter can seriously restrict airflow, making your unit work harder and reducing indoor air quality. Most homeowners should change their filters every 30 to 90 days, depending on usage and whether there are pets or allergies in the home.
Upgrading to a high-efficiency pleated filter can also help capture more dust, pollen, and pollutants; benefiting both your system and your health.
Get a Professional Tune-Up Each Spring
One of the best answers to how to make your air conditioner more efficient is simple: regular maintenance. A spring HVAC tune-up ensures that all components are clean, calibrated, and functioning at peak performance before the summer heat kicks in.
At City Wide Heating and Air, our AC maintenance service includes checking refrigerant levels, cleaning coils, tightening electrical connections, and inspecting ductwork for leaks. Preventative service not only improves efficiency but can also catch small issues before they become costly repairs.
Seal and Insulate Ductwork
Air loss through leaky ducts is a major cause of inefficiency, especially in older homes. If you’re researching how to make your air conditioner more efficient, don’t forget to look behind the walls and ceilings. Ducts that pass through unconditioned spaces like attics, crawlspaces, or garages should be sealed and insulated to prevent heat gain.
Professional duct sealing can drastically reduce energy loss and make sure the cool air you’re paying for actually makes it into your living space.
Use a Programmable Thermostat
Adjusting your thermostat manually is fine, but a programmable or smart thermostat can optimize your cooling schedule. If you're not home during the day, why cool an empty house? Learning thermostats can adapt to your habits and preferences, automatically adjusting temperatures to reduce energy use without sacrificing comfort.
Our thermostat installation services can help you take control of your home's energy efficiency while adding convenience and comfort.
Keep the Outdoor Unit Clear
The outdoor condenser unit is often overlooked, but it plays a major role in system efficiency. If it’s surrounded by grass, leaves, or other debris, airflow is restricted and heat can't escape efficiently. That means your system will use more energy to get the job done.
If you've been asking how to make your air conditioner more efficient, take a moment to inspect the outdoor unit. Trim back any vegetation and give the unit at least two feet of clearance on all sides.
Avoid Heat Buildup Indoors
Your AC works hard to remove heat from your home. You can give it a break by minimizing internal heat sources. That includes turning off lights and electronics when not in use, running heat-generating appliances like ovens and dryers in the evening, and keeping blinds or curtains closed during the hottest part of the day.
Reducing indoor heat gain is a simple but often overlooked solution to how to make your air conditioner more efficient.
Install Ceiling Fans
Ceiling fans don’t cool the air, but they help circulate it. This makes you feel cooler and allows you to raise the thermostat by a few degrees without feeling uncomfortable. Even a two- or three-degree increase in the thermostat setting can result in noticeable energy savings.
Pairing your AC system with ceiling fans is a smart, cost-effective strategy that directly supports your goal of how to make your air conditioner more efficient.
Consider an AC Upgrade If Yours Is Over 10 Years Old
Older air conditioning units are far less efficient than modern systems. If your unit is more than a decade old and you’ve been struggling with high bills or inconsistent cooling, it might be time to consider a replacement.
Newer models with ENERGY STAR® certification offer significant efficiency improvements. You may also be eligible for rebates or tax credits. Our air conditioner replacement services in Des Moines can help you find the perfect solution tailored to your home's size and budget.
Control Humidity Levels
High humidity can make your home feel warmer than it actually is, causing your AC to work harder. A whole-home dehumidifier can reduce moisture levels, helping you feel more comfortable at higher thermostat settings.
Humidity control is especially important in Iowa’s muggy summer climate. For homeowners wondering how to make your air conditioner more efficient, managing indoor moisture is a crucial piece of the puzzle.
Close Off Unused Rooms
If your home has rooms that aren’t frequently used consider closing the vents and doors to those spaces. Redirecting airflow can help concentrate cooling power in the rooms you actually use.
Just be cautious not to close off too many areas, which can lead to pressure imbalances and strain on your duct system. If you're unsure, schedule a consultation with our HVAC experts to evaluate the best setup for your home.
Use Window Treatments to Block Heat
Direct sunlight through windows can significantly raise indoor temperatures. Reflective window film, blackout curtains, or insulated shades can dramatically reduce heat gain, making it easier to keep your home cool without overworking your AC.
If you're tackling how to make your air conditioner more efficient without breaking the bank, energy-saving window treatments offer a strong return on investment.
Schedule Duct Cleaning if Needed
Over time, dust, pollen, and debris can accumulate inside your ductwork, restricting airflow and reducing efficiency. If you notice uneven cooling, rising energy bills, or unexplained allergy symptoms, it may be time for professional duct cleaning.

Upgrade Your Insulation
Insulation isn’t just a winter concern. It helps keep cool air in during the summer, too. Poor attic insulation is a common issue in many Des Moines homes, leading to excessive heat gain and reduced AC efficiency.
Upgrading your insulation is a long-term investment that supports your ongoing effort to figure out how to make your air conditioner more efficient. A well-insulated home requires less cooling, which translates to lower monthly bills.
Get an Energy Audit
A home energy audit can identify the specific reasons your air conditioner is underperforming. From leaky ductwork to insulation gaps and inefficient windows, you’ll get a full picture of where your energy is being wasted.
City Wide Heating and Air can connect you with trusted local energy professionals to perform a thorough audit and recommend improvements tailored to your home.
Train Your Household to Use Less Energy
Technology helps, but human habits matter too. Encourage family members to close doors quickly, turn off lights, and avoid adjusting the thermostat too often. When everyone is on the same page, your home becomes a more efficient, comfortable space for everyone.
Efficiency isn't a one-time fix, it’s a lifestyle. By shifting your habits, you can stretch the impact of every dollar you invest in your home cooling system.
