Hot summer weather can push even a well-maintained air conditioner to its limits. As temperatures in Moline continue to increase, it’s common to notice increased energy bills, uneven temperatures throughout the home and cooling systems that appear to run all day without keeping up. 

People often think the AC alone determines how comfortable your home feels. However, your home’s air circulation, insulation and shade all play a significant role in cooling performance.  

This guide highlights three simple strategies that can improve comfort and cooling efficiency: improving airflow in your home, making sure your home has proper insulation and creating shade to reduce heat from the sun. Using these summer AC tips from the pros at J.L. Brady Company LLC, you’ll keep your house cool in even the hottest weather. 

Start with Airflow: Improve Airflow for Better Cooling 

Air conditioners cool air and distribute it through ductwork to the rooms in your home. For that cool air to make rooms comfortable, it must move freely throughout your house. When airflow is blocked, some rooms may not cool properly. 

Many homeowners blame their air conditioning system for a hot home. The truth is, the AC is often working fine—the real problem is poor airflow. A clogged air filter, blocked vents and other HVAC issues can all restrict airflow. 

Home Airflow Improvement Tips 

Taking these easy steps to improve airflow in your home can improve comfort, reduce strain on your AC and lower energy costs. 

  • Replace dirty air filters. Regular AC air filter replacement helps your HVAC system circulate air more efficiently while supporting indoor air quality. 
  • Makesure supply and return vents are unblocked. Furniture, rugs and curtains can create blocked air vents that stop cooled air from circulating throughout your home. 
  • Keep interior doors open. This allows air to move more evenly between rooms. 
  • Move furniture covering registers.Making sure registers are free of obstructions allows conditioned air to circulate more easily. 
  • Book preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can check and clean dirty 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. Although your air conditioning removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation improves comfort, lowers cooling run times and can help maximize the life of your HVAC system. 

The attic is one of the largest sources of unwanted heat gain during heatwaves. Proper attic insulation and cooling work together because attic insulation slows heat transfer through the roof. Sealing gaps and sealing around doors and windows also help keep hot outdoor air from sneaking inside. 

If insulation levels are too low or air leaks let warm air into your home, your AC has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” In many cases, insufficient insulation—not the air conditioner—is the problem. 

Signs of Inadequate Home Insulation Levels 

  • Warmsecond-floor rooms 
  • Inconsistent room temperatures 
  • High utilitybills 
  • Air conditioner runningconstantly 

Use Shade to Keep Your Home Cooler 

Sunlight streaming through windows and heating your roof and exterior walls increases indoor temperatures, forcing your air conditioner to work harder. 

Direct sunlight can also reduce the efficiency of your outdoor AC unit by making it harder to release heat efficiently. Adding shade around your property can limit solar heat gain, improve comfort and reduce summer energy bills. Using trees or other landscaping to shade your air conditioner’s outdoor unit can also help—but never block airflow around the condenser. Keep away fences, enclosures or dense landscaping that restrict air movement. 

5 Summer AC Tips to Reduce Heat with Outdoor Shade 

  1. Add trees and landscaping strategically. Place trees to shade your roof, walls, windows and outdoor cooling equipment. If you’re shading your outdoor AC unit, keep at least 2–3 feet of clearance on all sides and 5 feet above the unit to maintain enough airflow. 
  2. Use window coverings. Light-colored curtains, cellular shades and thermal drapes reduce heat gain from sunlight shining through windows. 
  3. Use solar screens in your home. Solar screens, which are specially designed mesh curtains, used on sun-facing windows help reduce the sun’s heat while still providing natural light. 
  4. Make use of exterior shading. Use landscaping and design features like awnings, pergolas, shade sails or exterior shutters to stop direct sunlight off windows so it doesn’t heat up your home. 
  5. Close your blinds during the afternoon. Shut blinds or shades closed on west- and south-facing windows during the hottest part of the day to help reduce indoor temperatures and ease the load on your air conditioner. 

Additional Heat-Wave Survival Tips 

Airflow, insulation and shade can make a big difference, but these AC efficiency tips can further improve comfort during extreme summer heat. 

  • Change ceiling fan direction. Operate ceiling fans counterclockwise to provide a cooling breeze. 
  • Reduceuse of heat-generating appliances during the hottest part of the day. Run ovens, dryers and dishwashers in the morning or evening to reduce indoor heat. 
  • Set thermostat settings. Trytoavoid frequent temperature changes that force your AC to work harder. 
  • Schedule preventative maintenance. Regular service helps your system perform efficiently before peak cooling season.
  • Pay attention to unusual system performance. Take care of strange noises, weak airflow or inconsistent cooling before they become more expensive repairs. 

Recognize When It’s Time to Turn to an HVAC Professional 

DIY AC maintenance and energy-efficient cooling strategies can help, but some problems call for professional attention. When warm air is coming from your vents, airflow feels weak, your air conditioner runs almost constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, it’s a good idea to schedule an expert evaluation. 

At J.L. Brady Company LLC, our cooling specialists assess airflow, duct performance, insulation-related comfort concerns and overall system health to determine the underlying cause to help your HVAC system operate at its best throughout the summer.

Frequently Asked Questions About Cooling Your Home in Summer 

If your home is hot even though your AC is running, the problem isn’t always the AC. Poor airflow, too little insulation, incorrect thermostat settings or HVAC system issues can each reduce cooling performance and prevent cool air from reaching every room.

It can. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home stay cooler. When less heat enters 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.

Most households 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 type of filter, pets, allergies and how frequently your air conditioner runs.

Yes. Proper home insulation slows heat transfer into your home, reducing strain on your air conditioning. Making sure your home has appropriate insulation levels, especially in your attic or around windows, helps keep more consistent indoor temperatures while reducing energy.

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 AC unit is beneficial, but always maintain at least 2–3 feet of clearance around the unit and 5 feet above it to allow proper airflow.

For many homes, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during a heat wave. Set the highest temperature that keeps you comfortable, and try not to make large thermostat adjustments that force your air conditioning to work harder.
