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 seem to run all day without keeping up. 

People often 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 a significant role in cooling performance.  

This guide explains three practical strategies that can improve comfort and cooling efficiency: improving airflow in your home, making sure your home has proper insulation and using shade to reduce heat from the sun. By following these summer AC tips from the pros at Kapaun & Brown, you’ll keep your house cool in summer. 

Start with Airflow: Make Your Air Conditioner Work More Efficiently 

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

Many homeowners blame their air conditioner for poor cooling performance. In many cases, the AC is often working fine—the real problem is limited airflow. A clogged air filter, blocked vents and other HVAC issues can all prevent good airflow. 

Home Airflow Improvement Checklist 

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

  • Replace dirty air filters. Regular AC air filter replacement helps your HVAC system increase airflow while improving indoor air quality. 
  • Makesure supply and return vents are unblocked. Furniture, rugs and curtains can lead to blocked air vents that keep cooled air from circulating throughout your home. 
  • Keep interior doors open. This allows air to move more evenly between rooms. 
  • Reposition furniture covering registers.Making sure registers are free of obstructions allows conditioned air to circulate properly. 
  • Book preventiveAC maintenance services. During a professional HVAC tune-up, a technician can inspect and clean debris-covered blower components that may limit your system’s ability to circulate air. 

Insulation Is More Important Than You Might Expect 

Insulation provides a barrier against hot outdoor air. Although your air conditioner removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation improves comfort, reduces cooling run times and can help maximize the life of your HVAC system. 

The attic is one of the primary sources of unwanted heat gain during hot weather. Proper attic insulation and cooling are closely connected because attic insulation limits 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 let warm air into your home, your air conditioning has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” Frequently, the real problem is inadequate insulation, and the AC is not the problem. 

Signs of Inadequate Home Insulation Levels 

  • Upper floor rooms are always hot 
  • Hotand cold spots 
  • Higher cooling costs 
  • An air conditioner that rarely shuts off 

Use Shade to Help Lower Cooling Costs 

Sunlight coming through windows and heating up your roof and exterior walls boosts indoor temperatures, forcing your air conditioner to work harder. 

Direct sunlight can also impact your outdoor cooling unit by making it more difficult to release heat efficiently. Using shade around your property can reduce 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. Add trees and landscaping strategically. Place trees to shade your roof, walls, windows and outdoor cooling equipment. While providing shade for your outdoor AC unit, maintain at least 2–3 feet of clearance on all sides and 5 feet above the unit to maintain enough airflow. 
  2. Use window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from direct sunlight coming through windows. 
  3. Add 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. Strategically use outdoor shade. Add landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to keep direct sunlight off windows before it enters your home. 
  5. Lower blinds in the afternoon heat. Shut blinds or shades closed on west- and south-facing windows during the hottest part of the day to lower indoor temperatures and lighten the load on your AC. 

Additional Hot Weather Survival Tips 

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

  • Adjust ceiling fan direction. Operate ceiling fans counterclockwise to create a cooling breeze. 
  • Reduceuse of heat-generating appliances during the hottest part of the day. Operate ovens, dryers and dishwashers in the morning or evening to helpreduce indoor heat. 
  • Set thermostat settings. Don’t make frequent temperature changes that force your AC to work harder. 
  • Book preventative maintenance. Regular service helps your system perform efficiently before peak cooling season.
  • Watchfor unusual system performance. Take care of 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 need professional attention. If warm air is coming from your vents, airflow feels weak, your air conditioning seems to run constantly, energy bills suddenly increase, rooms cool unevenly or your system turns on and off repeatedly, you should consider an expert evaluation. 

At Kapaun & Brown, our cooling specialists inspect airflow, duct performance, insulation-related comfort concerns and overall system health to determine the underlying cause to help your HVAC system run 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 AC. Restricted airflow, inadequate insulation, inefficient thermostat settings or HVAC system issues can all reduce cooling performance and keep cool air from reaching every room.

It can. Trees, landscaping, awnings and window coverings help reduce solar heat gain, helping your home feel cooler. Less heat entering your home means your AC doesn’t have to work as hard to cool your home. That uses less 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 needed. Your recommended air filter replacement schedule depends on the type of filter, pets, allergies and the amount of time your air conditioner runs.

Yes. Proper home insulation limits heat transfer into your home, reducing the workload on your air conditioner. Ensuring 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 AC unit while it’s operating because the condenser needs open airflow to release heat. Providing shade for your outdoor air conditioner unit is a good idea, but always maintain at least 2–3 feet of clearance around the unit and 5 feet above it to maintain proper airflow.

For most homeowners, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during a heat wave. Choose the highest temperature that keeps you comfortable, and don’t make large thermostat adjustments that force your AC to work harder.
