Summer heat waves can push any air conditioner to the breaking point. As temperatures in Kearney climb, it’s common to notice increased energy bills, hot spots throughout the home and cooling systems that appear to run all day without keeping up. 

You may think the air conditioning is the only thing that affects 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 proper insulation and creating shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Thurston Heating & Air Conditioning, you’ll keep your house cool during heatwaves. 

Start with Airflow: Make Your Air Conditioner Work More Efficiently 

Air conditioners cool air and distribute it through ductwork to every room in your home. For that cool air to keep your home comfortable, it must be able to move freely throughout your house. When airflow is restricted, some rooms may not cool properly. 

Many people blame their air conditioning system for an uncomfortably hot home. In many cases, the AC is often working fine—the real problem is limited airflow. Dirty air filters, blocked vents and other HVAC issues can all reduce airflow. 

Home Airflow Optimization Strategies 

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

  • Replace dirty air filters. Routine AC air filter replacement helps your HVAC system circulate air more efficiently while supporting indoor air quality. 
  • Makesure supply and return vents are clear. Furniture, rugs and curtains can lead to blocked air vents that prevent cooled air from circulating throughout your home. 
  • Keep interior doors open. This helps 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. 
  • Schedule preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can examine and clean dirty blower components that may reduce your system’s ability to circulate air. 

Insulation Matters More Than Most Homeowners Realize 

Insulation acts as a barrier against outdoor heat. As your AC removes heat from inside your home, insulation helps stop heat from moving indoors. High-quality insulation improves comfort, lowers cooling run times and can help maximize the life of your HVAC system. 

The attic is one of the primary sources of solar heat gain during summer. 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 prevent hot outdoor air from getting inside. 

When insulation levels are too low or air leaks allow hot air to sneak inside, your air conditioning has to work harder. That often leads homeowners to ask, “Why is my house hot with the AC running?” In many cases, the real problem is inadequate insulation, and the AC is not the problem. 

Signs of Low Home Insulation Levels 

  • Upper floor rooms are always hot 
  • Inconsistent room temperatures 
  • Higher cooling costs 
  • Air conditioner runningconstantly 

Use Shade to Reduce Heat Gain 

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 affect your outdoor AC unit by reducing its ability to release heat efficiently. Using shade around your property can limit 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 block air movement. 

5 Summer AC Tips for Using Shade to Cool Your Home 

  1. Add trees and landscaping strategically. Position trees to shade your roof, walls, windows and outdoor AC 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. Install window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from sunlight shining through windows. 
  3. Use solar screens in your home. Solar screens, which are specially designed mesh curtains, placed on sun-facing windows help reduce the sun’s heat while still allowing in natural light. 
  4. Incorporate exterior shading. Use landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to keep direct sunlight off windows so it can’t heat up your home. 
  5. 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 reduce indoor temperatures and reduce the load on your cooling system. 

Additional Hot Weather 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. Operate ceiling fans counterclockwise to create a cooling breeze. 
  • Avoid heat-generating appliances during the hottest part of the day. Run ovens, dryers and dishwashers in the morning or evening to reduce indoor heat. 
  • Adjust thermostat settings. Don’t make frequent temperature changes that cause your AC to work harder. 
  • Book preventative maintenance. Professional service helps your system run efficiently before peak cooling season.
  • Pay attention to unusual system performance. Address strange noises, weak airflow or inconsistent cooling before they become more extensive repairs. 

Recognize When It’s Time to Contact an HVAC Professional 

Basic AC maintenance and energy-efficient cooling strategies can help, but some problems call for professional attention. If you notice warm air is coming from your vents, airflow feels weak, your AC runs almost constantly, energy bills increase for no reason, rooms cool unevenly or your system turns on and off repeatedly, you should consider an expert evaluation. 

At Thurston Heating & Air Conditioning, our cooling specialists inspect airflow, duct performance, insulation-related comfort concerns and overall system health to determine the real cause to help your HVAC system perform at its best throughout the summer.

Frequently Asked Questions About Summer AC Performance 

When your house stays hot even though your AC is running, the problem isn’t always the AC. Restricted airflow, too little insulation, improper 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 block solar heat gain, helping your home stay 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 saves energy, which helps decrease your cooling expenses.

For most homes, homeowners should check their air filter every month during the busiest cooling season and replace it as necessary. Your recommended air filter replacement schedule depends on the filter type, pets, allergies and how often your air conditioner runs.

It can. Proper home insulation reduces heat transfer into your home, reducing strain on your AC. Verifying your home has appropriate insulation levels, especially in your attic or around windows, helps create more consistent indoor temperatures while lowering energy.

Not while it’s running. You should never cover your outdoor air conditioning unit while it’s running because the condenser needs open airflow to release heat. Providing shade for your outdoor AC unit is a good idea, but always maintain at least 2–3 feet of clearance around the unit and 5 feet above it to provide proper airflow.

In many households, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during very hot weather. Use the highest temperature that keeps your family comfortable, and avoid large thermostat adjustments that force your AC to work harder.
