Hot summer weather can push your air conditioner to its limits. As temperatures in Wausau climb, many families notice rising energy bills, uneven temperatures throughout the home and cooling systems that appear to run all day without keeping up. 

People often think the air conditioner is the one thing that determines how comfortable your home feels. The fact is, your home’s air circulation, insulation and shade all play a major role in cooling performance.  

This guide explains three effective strategies that can improve comfort and cooling efficiency: increasing airflow in your home, making sure your home has enough insulation and adding shade to reduce heat from the sun. By following these summer AC tips from the pros at Gilray Heating and Cooling, you’ll keep your house cool in even the hottest weather. 

Start with Airflow: Make Your Air Conditioner Work More Efficiently 

AC units cool air and move it through ductwork to the rooms in your home. For that conditioned air to keep your home comfortable, it must move freely throughout your house. Whenever airflow is restricted, some rooms may stay warm. 

Many homeowners blame their AC for a hot home. In many cases, the AC is often working properly—the real problem is limited airflow. A dirty air filter, blocked vents and other HVAC issues can all inhibit airflow. 

Home Airflow Improvement Checklist 

Following these simple steps to improve airflow in your home can increase comfort, lower 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 supporting indoor air quality. 
  • Ensure supply and return vents are unblocked. Furniture, rugs and curtains can cause blocked air vents that prevent cooled air from circulating throughout your home. 
  • Open up doors in unused rooms. 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 properly. 
  • Arrange preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can check and clean dust-covered blower components that may reduce your system’s ability to circulate air. 

Insulation Matters More Than Most Homeowners Realize 

Insulation provides a barrier against outdoor heat. As your AC removes heat from inside your home, insulation helps stop heat from moving indoors. Better insulation increases comfort, decreases 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 summer. Proper attic insulation and cooling go hand in hand 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. 

Whenever 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?” Frequently, insufficient insulation—not the air conditioner—is the problem. 

Signs of Inadequate Home Insulation Levels 

  • Upper floor rooms are always hot 
  • Inconsistent room temperatures 
  • Risingenergy bills 
  • AnAC system that runs nonstop 

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 air conditioning unit by reducing its ability to release heat efficiently. Using shade around your property can minimize solar heat gain, improve comfort and lower summer energy bills. Using trees or other landscaping to shade your air conditioner’s outdoor unit can also help—but never obstruct airflow around the condenser. Don’t install 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. Use 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 ensure it receives enough airflow. 
  2. Add window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from sunlight shining 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 letting in 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 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 lower indoor temperatures and reduce the load on your air conditioning system. 

Additional Heat-Wave Survival Tips 

Airflow, insulation and shade all make a big difference, but these AC efficiency tips can also increase comfort during intense summer heat. 

  • Change ceiling fan direction. Run ceiling fans counterclockwise to provide 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. 
  • Adjust thermostat settings. Don’t make frequent temperature changes that force your AC to work harder. 
  • Book preventative maintenance. Professional service helps your system run efficiently before peak cooling season.
  • Watchfor 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 Contact 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 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 Gilray Heating and Cooling, our cooling specialists evaluate airflow, duct performance, insulation-related comfort concerns and overall system health to determine the underlying 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 air conditioner. Poor airflow, too little insulation, improper thermostat settings or HVAC system issues can all affect cooling performance and stop cool air from reaching every room.
Absolutely. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home remain cooler. Reducing the amount of heat entering your home means your air conditioning doesn’t have to work as hard to cool your home. That saves energy, which can lower 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 air filter you use, pets, allergies and the amount of time your air conditioner runs.

Absolutely. Proper home insulation reduces heat transfer into your home, reducing the workload on your air conditioning. Verifying your home has appropriate insulation levels, especially in your attic or around windows, helps keep more consistent indoor temperatures while lowering energy.

You shouldn’t. You should never cover your outdoor air conditioning unit while it’s running because the condenser needs unobstructed airflow to release heat. Providing shade for your outdoor AC 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 allow 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 hot summer weather. Use the highest temperature that keeps your family comfortable, and don’t make large thermostat adjustments that force your air conditioning to work harder.
