Summer heat waves can push your air conditioner to its limits. As temperatures in Pella rise, many homeowners notice higher energy bills, hot spots throughout the home and cooling systems that often run all day without keeping up.
It’s easy to assume 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 simple strategies that can improve comfort and cooling efficiency: boosting airflow in your home, making sure your home has adequate insulation and using shade to reduce heat from the sun. Using these summer AC tips from the pros at Van Haaften Plumbing & Heating, you’ll keep your house cool in summer.
Start with Airflow: Improve Airflow for Better Cooling
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 be able to move freely throughout the house. When airflow is restricted, some rooms may stay warm.
Many homeowners blame their air conditioner for a hot home. The truth is, the AC is often working fine—the real problem is restricted airflow. Dirty air filters, blocked vents and other HVAC issues can all inhibit airflow.
Home Airflow Optimization Strategies
Taking steps to boost airflow in your home can improve comfort, lower strain on your AC and lower energy costs.
- Change dirty air filters. Routine AC air filter replacement helps your HVAC system circulate air more efficiently while supporting indoor air quality.
- Ensure supply and return vents are clear. Furniture, rugs and curtains can lead to blocked air vents that stop cooled air from circulating throughout your home.
- Keep interior doors open. This allows air to move more evenly between rooms.
- Reposition furniture covering registers.Keeping registers clear allows conditioned air to circulate properly.
- Arrange preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can examine and clean dirty blower components that may limit your system’s ability to circulate air.
Insulation Plays a Bigger Role Than Many Homeowners Think
Insulation acts as a barrier against outdoor heat. Although your AC removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation enhances comfort, lowers 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 slows heat transfer through the roof. Proper weatherstripping and sealing around doors and windows also help prevent hot outdoor air from sneaking inside.
If insulation levels are too low or air leaks are present, your air conditioner 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 Poor Home Insulation Levels
- Warmsecond-floor rooms
- Uneventemperatures
- Higher cooling costs
- An air conditioner that rarely shuts off
Use Shade to Keep Your Home Cooler
Sunlight shining through windows and warming your roof and exterior walls boosts indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also impact your outdoor air conditioning unit by making it more difficult to release heat efficiently. Adding shade around your property can minimize solar heat gain, improve comfort and reduce summer energy bills. Shading your air conditioner’s outdoor unit can also help—but never block airflow around the condenser. Avoid fences, enclosures or dense landscaping that restrict air movement.
5 Summer AC Tips for Keeping Your Home Cooler with Shade
- Add trees and landscaping strategically. Position trees to shade your roof, walls, windows and outdoor AC 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 ensure it receives enough airflow.
- Install window coverings. Light-colored curtains, cellular shades and thermal drapes reduce heat gain from sun streaming through windows.
- Add 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.
- Strategically use exterior shading. Use landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to stop direct sunlight off windows so it can’t heat up your home.
- 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 help reduce indoor temperatures and ease the load on your AC.
Additional Hot Weather Survival Tips
Airflow, insulation and shade 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.
- Limit heat-generating appliances during the hottest part of the day. Use ovens, dryers and dishwashers in the morning or evening to limit indoor heat.
- Adjust thermostat settings. Trytoavoid frequent temperature changes that cause your AC to work harder.
- Arrange preventative maintenance. Professional service helps your system run efficiently before peak cooling season.
- Pay attention to unusual system performance. Call a professional to investigate strange noises, weak airflow or inconsistent cooling before they become more expensive repairs.
Know 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 you notice warm air is coming from your vents, airflow feels weak, your air conditioner seems to run constantly, energy bills increase for no reason, rooms cool unevenly or your system turns on and off repeatedly, it’s a good idea to schedule an expert evaluation.

Frequently Asked Questions About Summer AC Performance
Why is my house still warm even when the air conditioning is operating?
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, inefficient thermostat settings or HVAC system issues can all affect cooling performance and prevent cool air from reaching every room.
Does outdoor shade really help cut cooling costs?
Absolutely. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home remain cooler. Less heat entering your home means your AC doesn’t have to work as hard to cool your home. That saves energy, which can lower your cooling expenses.
How often should I change my HVAC air filter throughout the cooling season?
For most homes, homeowners 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 often your air conditioner runs.
Can insulation {help|make my air conditioner work better?
Yes. Proper home insulation slows 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 maintain more consistent indoor temperatures while reducing energy.
Should I cover up my outdoor AC unit to keep it cooler?
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. Adding 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 allow proper airflow.
What temperature should I set my thermostat at during a heat wave?
For most homeowners, setting the thermostat around 78 degrees when you’re home offers the right balance of comfort and energy efficiency during a heat wave. Choose the highest temperature that keeps your family comfortable, and avoid large thermostat adjustments that force your AC to work harder.
