Hot summer weather can push even a well-maintained air conditioner to the breaking point. As temperatures in Marshalltown climb, many homeowners notice rising energy bills, uneven temperatures throughout the home and cooling systems that appear to run all day without keeping up. 

It’s easy to assume the AC is the only thing that affects how comfortable your home feels. In reality, your home’s airflow, insulation and shade all play a major role in cooling performance.  

This guide explains three effective strategies that can enhance comfort and cooling efficiency: increasing airflow in your home, making sure your home has enough insulation and creating shade to reduce heat from the sun. When you follow these summer AC tips from the pros at B & G HVAC, you’ll keep your house cool during heatwaves. 

Start with Airflow: Help Your AC Work Smarter 

Air conditioners cool the air and send it through ductwork to every room in your home. For that cool air to cool every room effectively, it has to move freely throughout your home. Whenever airflow is restricted, some rooms may feel warmer than others. 

Many homeowners blame their air conditioner for a hot home. 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 reduce airflow. 

Home Airflow Improvement Strategies 

Taking steps to improve airflow in your home can increase comfort, minimize strain on your AC and lower energy costs. 

  • Change dirty air filters. Regular AC air filter replacement helps your HVAC system circulate air more efficiently while improving indoor air quality. 
  • Check that supply and return vents are free from obstructions. Furniture, rugs and curtains can cause blocked air vents that keep cooled air from circulating throughout your home. 
  • Keep interior doors open. Doing so helps air to move more evenly between rooms. 
  • Reposition furniture covering registers.Making sure registers are uncovered allows conditioned air to circulate more easily. 
  • Book preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can check and clean debris-covered 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. As your air conditioner removes heat from inside your home, insulation helps prevent outdoor heat from entering. High-quality insulation improves comfort, reduces 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 hot weather. Proper attic insulation and cooling go hand in hand because attic insulation limits heat transfer through the roof. Sealing gaps and sealing around doors and windows also help prevent hot outdoor air from entering your home. 

If insulation levels are too low or air leaks allow hot air to sneak inside, your AC has to work harder. As a result, many homeowners 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 Poor Home Insulation Levels 

  • Upper floor rooms are always hot 
  • Uneventemperatures 
  • Higher cooling costs 
  • AnAC system that runs nonstop 

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 impact your outdoor AC unit by making it harder to release heat efficiently. Adding shade around your property can reduce solar heat gain, improve comfort and decrease summer energy bills. Putting in shade over 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 limit air movement. 

5 Summer AC Tips for Using Shade to Cool Your Home 

  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. Add window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from sunlight shining through windows. 
  3. Add 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. Strategically use 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 reduce indoor temperatures and reduce the load on your cooling system. 

Additional Summer Heat Survival Tips 

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

  • Change ceiling fan direction. Run ceiling fans counterclockwise to create a cooling breeze. 
  • Limit 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. Avoid frequent temperature changes that force your AC to work harder. 
  • Schedule preventative maintenance. Regular service helps your system run 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 Call an HVAC Professional 

DIY 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 conditioning seems to run constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, it’s time for an expert evaluation. 

At B & G HVAC, our cooling specialists assess 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 

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

It can. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home remain cooler. Less heat entering your home means your cooling system doesn’t have to work as hard to cool your home. This reduces 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 needed. Your recommended air filter replacement schedule depends on the type of filter, pets, allergies and how frequently your air conditioner runs.

Absolutely. Proper home insulation slows heat transfer into your home, reducing the workload on your air conditioner. Making sure your home has adequate 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 AC unit while it’s operating because the condenser needs unrestricted airflow to release heat. Creating shade for your outdoor air conditioning unit is helpful, 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 an excellent balance of comfort and energy efficiency during a heat wave. Use the highest temperature that keeps your family comfortable, and try not to make large thermostat adjustments that force your air conditioning to work harder.
