How to Lower Your Energy Bills This Summer in Missouri

If you are looking for ways to lower your energy bills this summer, you are not alone. Missouri homeowners see their electricity costs spike dramatically between June and September, and most of that increase comes from running the air conditioner around the clock.

The combination of high humidity and temperatures in the mid-90s makes the St. Louis area and surrounding regions some of the most energy-intensive places to cool a home in the Midwest. Your AC is fighting against solar heat gain through windows, poor insulation, and the sheer intensity of Missouri summers.

The good news is that you do not need to sacrifice comfort to save money. There are practical, proven strategies that reduce your cooling costs without making your home feel like a sauna. This guide walks through the most effective ones, starting with the changes that deliver the biggest return.

Start With Your Windows: The Biggest Source of Heat Gain

Up to 30 percent of your home's cooling load comes from heat entering through windows. That is a staggering number, and it explains why your AC runs nonstop on sunny days even when your thermostat is set at a reasonable temperature.

Solar window film is one of the most cost-effective upgrades you can make. It blocks a large percentage of the sun's infrared energy before it passes through your glass, which means your AC does not have to work as hard to maintain a comfortable temperature.

For Missouri homeowners, this is especially impactful on south-facing and west-facing windows that take direct afternoon sun. A professional installation typically pays for itself within two to three cooling seasons through energy savings alone. Check out our Residential Solar Tinting Page to see how it works.

Optimize Your Thermostat Settings

Setting your thermostat to 78 degrees when you are home and 85 degrees when you are away can cut your cooling costs by 10 to 15 percent. Every degree below 78 increases your energy use by about three percent.

A programmable or smart thermostat makes this effortless. Set it to start cooling your home 30 minutes before you arrive, and you walk into comfort without paying to cool an empty house all day.

If 78 feels too warm, ceiling fans can make a room feel four to six degrees cooler through wind chill. That lets you keep the thermostat higher without sacrificing comfort.

Seal Air Leaks and Improve Insulation

Air leaks around windows, doors, and ductwork let cooled air escape and hot air infiltrate your home. In older homes across the Missouri and Illinois region, this is one of the most overlooked sources of wasted energy.

Check weatherstripping around doors and windows. If you can see daylight or feel warm air coming in, it is time to replace it. Caulking around window frames is another inexpensive fix that makes a measurable difference.

Attic insulation is equally important. Heat radiates through your roof and into your living space, and without adequate insulation, your AC is fighting a losing battle. The Department of Energy recommends R-38 to R-60 insulation for attics in our climate zone.

Use Window Coverings Strategically

If you do not have window film yet, keeping blinds and curtains closed during peak sun hours helps reduce heat gain. Light-colored window coverings reflect more heat than dark ones.

That said, window coverings are a band-aid compared to window film. Curtains block light but trap heat between the fabric and the glass, which still radiates into your room. Window film stops heat at the glass surface, which is fundamentally more effective.

Consider Your Landscaping

Strategic shade trees on the south and west sides of your home can reduce cooling costs by up to 25 percent over time. Deciduous trees are ideal because they provide shade in summer and let sunlight through in winter.

This is a longer-term investment, but if you are planning any landscaping work, positioning trees to shade your most sun-exposed windows pays dividends for decades.

Maintain Your HVAC System

A dirty air filter forces your AC to work harder and use more energy. Replace your filter every 30 to 60 days during summer, or more often if you have pets.

Schedule an annual tune-up before the cooling season starts. A technician can check refrigerant levels, clean coils, and make sure your system is running at peak efficiency. A well-maintained system uses 15 to 20 percent less energy than a neglected one.

Also check your outdoor unit. Clear away debris, trim vegetation to at least two feet around the condenser, and make sure the fins are clean. Restricted airflow around the outdoor unit directly reduces efficiency.
