Summer heat waves can push your air conditioner to its limits. As temperatures in Shamokin and Sunbury rise, many homeowners notice increased energy bills, hot spots 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 an important role in cooling performance.  

This guide highlights three effective strategies that can improve comfort and cooling efficiency: increasing airflow in your home, making sure your home has adequate insulation and adding shade to reduce heat from the sun. Using these summer AC tips from the pros at LTS Plumbing & Heating Inc., 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 move it through ductwork to rooms in your home. For that conditioned air to keep your home comfortable, it has to move freely throughout the house. Whenever airflow is blocked, some rooms may not cool properly. 

It’s common for homeowners to blame their AC for poor cooling performance. However, the AC is often working just fine—the real problem is poor airflow. A dirty air filter, blocked vents and other HVAC issues can all prevent good airflow. 

Home Airflow Optimization Tips 

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

  • Swapout dirty air filters. Regular AC air filter replacement helps your HVAC system circulate air more efficiently while supporting indoor air quality. 
  • Ensure supply and return vents are free from obstructions. Furniture, rugs and curtains can cause blocked air vents that stop cooled air from circulating throughout your home. 
  • Open up doors in unused rooms. This allows air to move more evenly between rooms. 
  • Relocate furniture covering registers.Keeping registers clear allows conditioned air to circulate freely. 
  • 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 outdoor heat. Although your air conditioner removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation improves comfort, decreases cooling run times and can help extend the life of your HVAC system. 

The attic is one of the biggest sources of unwanted heat gain during heatwaves. Proper attic insulation and cooling are closely connected because attic insulation reduces heat transfer through the roof. Sealing gaps and sealing around doors and windows also help stop hot outdoor air from getting inside. 

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

Signs of Low Home Insulation Levels

  • Hotand cold spots 
  • High utilitybills 
  • Air conditioner runningconstantly 

Use Shade to Help Lower Cooling Costs 

Sunlight shining through windows and warming your roof and exterior walls raises indoor temperatures, forcing your air conditioner to work harder. 

Direct sunlight can also affect your outdoor cooling unit by reducing its ability to release heat efficiently. Creating 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. Don’t install fences, enclosures or dense landscaping that restrict air movement. 

5 Summer AC Tips for Keeping Your Home Cooler with Shade 

  1. Plant trees and landscaping strategically. Position 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. Add window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from direct sunlight coming through windows. 
  3. Install solar screens in your home. Solar screens, which are specially designed mesh curtains, placed on sun-facing windows help limit the sun’s heat while still providing natural light. 
  4. Incorporate exterior shading. Add landscaping and design features like awnings, pergolas, shade sails or exterior shutters to block direct sunlight off windows so it can’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 reduce indoor temperatures and reduce the load on your air conditioning system. 

Additional Summer Heat Survival Tips 

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

  • Settheappropriate ceiling fan direction. Rotate ceiling fans counterclockwise to provide 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 helpreduce indoor heat. 
  • Adjust thermostat settings. Trytoavoid frequent temperature changes that cause your AC to work harder. 
  • Schedule preventative maintenance. Professional service helps your system run efficiently before peak cooling season.
  • Watchfor unusual system performance. Call a professional to investigate strange noises, weak airflow or inconsistent cooling before they become more extensive repairs. 

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

At-home AC maintenance and energy-saving 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 seems to run constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, you should consider an expert evaluation.

Frequently Asked Questions About Cooling Your Home in Summer 

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

Yes. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home feel cooler. Less heat entering your home means your air conditioner doesn’t have to work as hard to cool your home. That uses less energy, which can lower your cooling expenses.

Most homeowners should check their air filter every month during the peak cooling season and replace it as needed. The best air filter replacement schedule depends on the air filter you use, 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 keep more consistent indoor temperatures while reducing energy.

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

For many homes, setting the thermostat around 78 degrees when you’re home offers the right balance of comfort and energy efficiency during very hot weather. Set the highest temperature that keeps you comfortable, and avoid large thermostat adjustments that force your air conditioning to work harder.
