Summer heat waves can push any air conditioner to the edge. As temperatures in Siloam Springs rise, it’s common to notice rising energy bills, uneven temperatures throughout the home and cooling systems that seem to run all day without keeping up. 

You may think the AC is the one thing that 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 effective strategies that can enhance comfort and cooling efficiency: boosting airflow in your home, making sure your home has adequate insulation and using shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Siloam Springs Heating & AC, you’ll keep your house cool during heatwaves. 

Start with Airflow: Make Your Air Conditioner Work More Efficiently 

AC units lower the temperature of air and send it through ductwork to the rooms in your home. For that cool air to cool every room effectively, it must be able to move freely throughout your house. When airflow is restricted, some rooms may stay warm. 

Many people blame their air conditioning system for an uncomfortably hot home. The truth is, the AC is often working properly—the real problem is restricted airflow. A clogged air filter, blocked vents and other HVAC issues can all limit airflow. 

Home Airflow Improvement Checklist 

Taking these easy steps to boost airflow in your home can enhance comfort, minimize strain on your AC and decrease energy costs. 

  • Swapout dirty air filters. Routine AC air filter replacement helps your HVAC system move air more effectively while supporting indoor air quality. 
  • Ensure supply and return vents are free from obstructions. Furniture, rugs and curtains can lead to blocked air vents that prevent cooled air from circulating throughout your home. 
  • Keep interior doors open. Doing so helps air to move more evenly between rooms. 
  • Relocate furniture covering registers.Keeping registers clear allows conditioned air to circulate properly. 
  • Arrange preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can check and clean dirty blower components that may affect your system’s ability to circulate air. 

Insulation Plays a Bigger Role Than Many Homeowners Think 

Insulation acts as a barrier against hot outdoor air. As your air conditioner removes heat from inside your home, insulation helps prevent outdoor heat from entering. Better insulation improves comfort, reduces cooling run times and can help maximize the life of your HVAC system. 

The attic is one of the biggest sources of solar heat gain during heatwaves. Proper attic insulation and cooling go hand in hand because attic insulation slows heat transfer through the roof. Proper weatherstripping and sealing around doors and windows also help stop hot outdoor air from entering your home. 

Whenever insulation levels are too low or air leaks are present, your air conditioner has to work harder. This often causes homeowners to ask, “Why is my house hot with the AC running?” In many cases, home insulation levels—not the air conditioner—are the problem. 

Signs of Poor Home Insulation Levels 

  • Warmsecond-floor rooms 
  • Hotand cold spots 
  • Higher cooling costs 
  • An air conditioner that rarely shuts off 

Use Shade to Keep Your Home Cooler 

Sunlight shining 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 cooling unit by reducing its ability to release heat efficiently. Creating shade around your property can minimize solar heat gain, improve comfort and lower summer energy bills. Putting in shade over your air conditioner’s outdoor unit can also help—but never block airflow around the condenser. Don’t install fences, enclosures or dense landscaping that limit air movement. 

5 Summer AC Tips for Using Shade to Cool Your Home 

  1. Add trees and landscaping strategically. Use trees to shade your roof, walls, windows and outdoor cooling equipment. While providing shade for your outdoor AC unit, keep at least 2–3 feet of clearance on all sides and 5 feet above the unit to allow for enough airflow. 
  2. Install window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from sunlight shining through windows. 
  3. Install 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 allowing in natural light. 
  4. Incorporate exterior shading. Add landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to keep direct sunlight off windows so it doesn’t heat up your home. 
  5. Close your blinds during the afternoon. Leave blinds or shades closed on west- and south-facing windows during the hottest part of the day to help reduce indoor temperatures and reduce the load on your air conditioner. 

Additional Summer Heat Survival Tips 

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

  • Settheappropriate ceiling fan direction. Run ceiling fans counterclockwise to create a cooling breeze. 
  • Avoid heat-generating appliances during the hottest part of the day. Use ovens, dryers and dishwashers in the morning or evening to helpreduce indoor heat. 
  • Set thermostat settings. Don’t make frequent temperature changes that make your AC to work harder. 
  • Book preventative maintenance. Regular service helps your system operate efficiently before peak cooling season.
  • Pay attention to unusual system performance. Call a professional to investigate strange noises, weak airflow or inconsistent cooling before they become more extensive repairs. 

The Importance of Knowing When It’s Time to Contact an HVAC Professional 

Basic AC maintenance and efficiency-focused 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 suddenly increase, rooms cool unevenly or your system turns on and off repeatedly, it’s a good idea to schedule an expert evaluation. 

At Siloam Springs Heating & AC, our cooling specialists assess airflow, duct performance, insulation-related comfort concerns and overall system health to identify the actual cause to help your HVAC system perform at its best throughout the summer.

Frequently Asked Questions About Summer Air Conditioner Efficiency 

If your living space remains hot even though your AC is running, the problem isn’t always the air conditioner. Limited airflow, inadequate insulation, improper thermostat settings or HVAC system issues can all reduce cooling performance and prevent cool air from reaching every room.

Yes. Trees, landscaping, awnings and window coverings help reduce solar heat gain, helping your home remain cooler. Reducing the amount of heat entering your home means your cooling system doesn’t have to work as hard to cool your home. That uses less energy, which helps decrease your cooling expenses.

Most households should check their air filter every month during the busiest cooling season and replace it as necessary. The ideal air filter replacement schedule depends on the filter type, pets, allergies and the amount of time your air conditioner runs.

Yes. Proper home insulation reduces 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 maintain more consistent indoor temperatures while lowering energy.

Not while it’s running. You should never cover your outdoor AC unit while it’s operating because the condenser needs open airflow to release heat. Adding shade for your outdoor air conditioning unit is helpful, but always make sure there’s 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 your family comfortable, and don’t make large thermostat adjustments that force your air conditioning to work harder.
