Extreme summer heat can push your air conditioner to the breaking point. As temperatures in Seymour climb, it’s common to notice increased energy bills, warm areas throughout the home and cooling systems that appear to run all day without keeping up.
You may think the AC alone determines how comfortable your home feels. The fact is, your home’s air circulation, insulation and shade all play an important role in cooling performance.
This guide covers three simple strategies that can increase comfort and cooling efficiency: improving airflow in your home, making sure your home has adequate insulation and creating shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Diedrick's Heating and Air Conditioning, you’ll keep your house cool in summer.
Start with Airflow: Make Your Air Conditioner Work More Efficiently
Air conditioners lower the temperature of air and send it through ductwork to rooms in your home. For that cool air to make rooms comfortable, it must be able to move freely throughout the house. Whenever airflow is restricted, some rooms may feel warmer than others.
Many people blame their air conditioning system for poor cooling performance. The truth is, the AC is often working properly—the real problem is poor airflow. Dirty air filters, blocked vents and other HVAC issues can all reduce airflow.
Home Airflow Optimization Checklist
Taking steps to improve airflow in your home can increase comfort, minimize strain on your AC and reduce energy costs.
- Replace dirty air filters. Consistent AC air filter replacement helps your HVAC system circulate air more efficiently while helping improve indoor air quality.
- Check that supply and return vents are clear. Furniture, rugs and curtains can cause blocked air vents that keep cooled air from circulating throughout your home.
- Keep interior doors open. Doing so helps air to move more evenly between rooms.
- Reposition furniture covering registers.Making sure registers are free of obstructions allows conditioned air to circulate more easily.
- Schedule preventiveAC maintenance services. During a professional HVAC tune-up, a technician can examine and clean dust-covered blower components that may reduce your system’s ability to circulate air.
Insulation Plays a Bigger Role Than Many Homeowners Think
Insulation serves as a barrier against the warm air outside your home. As your AC removes heat from inside your home, insulation helps stop heat from moving indoors. High-quality insulation enhances comfort, lowers cooling run times and can help increase the life of your HVAC system.
The attic is one of the primary sources of unwanted heat gain during hot weather. Proper attic insulation and cooling work together because attic insulation slows heat transfer through the roof. Proper weatherstripping and sealing around doors and windows also help stop hot outdoor air from sneaking inside.
If insulation levels are too low or air leaks allow hot air to sneak inside, your AC has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” Frequently, home insulation levels—not the air conditioner—are the problem.
Signs of Inadequate Home Insulation Levels
- Warmsecond-floor rooms
- Inconsistent room temperatures
- Risingenergy bills
- An air conditioner that rarely shuts off
Use Shade to Keep Your Home Cooler
Sunlight shining through windows and heating up your roof and exterior walls boosts indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also impact your outdoor AC unit by making it harder to release heat efficiently. Creating shade around your property can minimize solar heat gain, improve comfort and lower summer energy bills. Shading your air conditioner’s outdoor unit can also help—but never obstruct airflow around the condenser. Avoid fences, enclosures or dense landscaping that limit air movement.
5 Summer AC Tips to Reduce Heat with Outdoor Shade
- Plant trees and landscaping strategically. Use trees to shade your roof, walls, windows and outdoor AC equipment. When shading your outdoor AC unit, maintain at least 2–3 feet of clearance on all sides and 5 feet above the unit to maintain enough airflow.
- Use window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from sun streaming through windows.
- Use solar screens in your home. Solar screens, which are specially designed mesh curtains, used on sun-facing windows help limit the sun’s heat while still providing natural light.
- Strategically use outdoor shade. Use landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to stop direct sunlight off windows before it enters your home.
- Keep blinds closed during high heat. Leave blinds or shades closed on west- and south-facing windows during the hottest part of the day to lower indoor temperatures and ease the load on your cooling system.
Additional Heat-Wave Survival Tips
Airflow, insulation and shade make a big difference, but these AC efficiency tips can also increase comfort during extreme summer heat.
- Adjust ceiling fan direction. Operate ceiling fans counterclockwise to provide a cooling breeze.
- Limit heat-generating appliances during the hottest part of the day. Run ovens, dryers and dishwashers in the morning or evening to limit indoor heat.
- Manage thermostat settings. Avoid frequent temperature changes that force your AC to work harder.
- Book preventative maintenance. Professional service helps your system operate efficiently before peak cooling season.
- Monitor unusual system performance. Take care of strange noises, weak airflow or inconsistent cooling before they become more extensive repairs.
The Importance of Knowing When It’s Time to Turn to an HVAC Professional
Basic AC maintenance and efficiency-focused cooling strategies can help, but some problems require professional attention. If you notice warm air is coming from your vents, airflow feels weak, your air conditioner seems to run constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, it’s time for an expert evaluation.

Frequently Asked Questions About Cooling Your Home in Summer
Why is my home still hot even when the air conditioner is on?
If your home is hot even though your AC is running, the problem isn’t always the AC. Limited airflow, inadequate insulation, incorrect thermostat settings or HVAC system issues can all reduce cooling performance and prevent cool air from reaching every room.
Does outdoor shade really help reduce cooling costs?
It can. Trees, landscaping, awnings and window coverings block solar heat gain, helping your home stay cooler. Less heat entering your home means your cooling system doesn’t have to work as hard to cool your home. That saves energy, which helps reduce your cooling expenses.
How often should I replace my HVAC air filter throughout the cooling season?
Most homeowners should check their air filter every month during the busiest cooling season and replace it as needed. Your recommended air filter replacement schedule depends on the air filter you use, pets, allergies and how frequently your air conditioner runs.
Can insulation {help|make my air conditioner perform better?
It can. Proper home insulation limits heat transfer into your home, reducing the workload on your air conditioner. Making sure your home has appropriate insulation levels, especially in your attic or around windows, helps create more consistent indoor temperatures while reducing energy.
Should I put a cover over my outdoor AC unit during hot weather?
No. You should never cover your outdoor AC unit while it’s operating because the condenser needs unobstructed airflow to release heat. Creating shade for your outdoor air conditioner unit is a good idea, but always keep at least 2–3 feet of clearance around the unit and 5 feet above it to provide proper airflow.
What temperature should I keep my thermostat at when it’s hot outside?
For many homes, setting the thermostat around 78 degrees when you’re home offers an excellent balance of comfort and energy efficiency during very hot weather. Set the highest temperature that keeps your family comfortable, and don’t make large thermostat adjustments that force your air conditioner to work harder.
