Extreme summer heat can push your air conditioner to its limits. As temperatures in Modesto continue to increase, many families notice higher energy bills, uneven temperatures throughout the home and cooling systems that seem to run all day without keeping up.
It’s easy to assume the AC alone determines how comfortable your home feels. The fact is, your home’s air circulation, insulation and shade all play an important role in cooling performance.
This guide highlights three practical strategies that can improve comfort and cooling efficiency: improving airflow in your home, making sure your home has adequate insulation and creating shade to reduce heat from the sun. By following these summer AC tips from the pros at Jet Electrical, Air Conditioning, Heating & Plumbing, you’ll keep your house cool during heatwaves.
Start with Airflow: Make Your Air Conditioner Work More Efficiently
Air conditioners lower the temperature of air and distribute it through ductwork to rooms in your home. For that conditioned air to make rooms comfortable, it must be able to move freely throughout the house. When airflow is restricted, some rooms may stay warm.
Many people blame their AC for poor cooling performance. In many cases, the AC is often working fine—the real problem is restricted airflow. A dirty air filter, blocked vents and other HVAC issues can all inhibit airflow.
Home Airflow Optimization Tips
Taking these easy steps to boost airflow in your home can improve comfort, reduce strain on your AC and reduce energy costs.
- Replace dirty air filters. Consistent AC air filter replacement helps your HVAC system increase airflow while improving indoor air quality.
- Check that supply and return vents are free from obstructions. Furniture, rugs and curtains can create 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.
- Relocate furniture covering registers.Making sure registers are uncovered allows conditioned air to circulate more easily.
- Schedule 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 Is More Important Than You Might Expect
Insulation serves as a barrier against hot outdoor air. Although your air conditioning removes heat from inside your home, insulation helps prevent outdoor heat from entering. High-quality insulation increases comfort, lowers cooling run times and can help increase 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 go hand in hand because attic insulation slows heat transfer through the roof. Weatherstripping and sealing around doors and windows also help prevent hot outdoor air from getting inside.
If insulation levels are too low or air leaks allow hot air to sneak inside, your air conditioner has to work harder. This often causes homeowners to ask, “Why is my house hot with the AC running?” In many cases, insufficient insulation—not the air conditioner—is the problem.

Use Shade to Keep Your Home Cooler
Sunlight coming through windows and warming your roof and exterior walls increases indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also affect your outdoor air conditioning unit by reducing its ability to release heat efficiently. Creating shade around your property can minimize 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 block airflow around the condenser. Avoid fences, enclosures or dense landscaping that limit air movement.
5 Summer AC Tips for Using Shade to Cool Your Home
- Plan trees and landscaping strategically. Position trees to shade your roof, walls, windows and outdoor air conditioning 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 limit heat gain from sunlight shining through windows.
- Install solar screens in your home. Solar screens, which are specially designed mesh curtains, placed on sun-facing windows help block the sun’s heat while still letting in natural light.
- Incorporate outdoor shade. Use landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to block direct sunlight off windows so it doesn’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 Heat-Wave 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 provide a cooling breeze.
- Reduceuse of heat-generating appliances during the hottest part of the day. Use ovens, dryers and dishwashers in the morning or evening to reduce indoor heat.
- Adjust thermostat settings. Avoid frequent temperature changes that cause your AC to work harder.
- Arrange preventative maintenance. Regular 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 extensive repairs.
Know When It’s Time to Contact an HVAC Professional
At-home AC maintenance and energy-efficient cooling strategies can help, but some problems call for professional attention. If warm air is coming from your vents, airflow feels weak, your air conditioning seems to run constantly, energy bills increase for no reason, rooms cool unevenly or your system turns on and off repeatedly, it’s time for an expert evaluation.

Frequently Asked Questions About Summer Air Conditioner Efficiency
Why is my house still hot even when the air conditioning is running?
If your living space remains hot even though your AC is running, the problem isn’t always your AC. Limited airflow, too little insulation, incorrect thermostat settings or HVAC system issues can all affect cooling performance and stop 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. When less heat enters 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.
How often should I replace my HVAC air filter throughout the cooling season?
Most households 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 how often your air conditioner runs.
Can insulation {help|make my air conditioner run more efficiently?
Yes. Proper home insulation slows 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 maintain more consistent indoor temperatures while using less energy.
Should I cover up my outdoor AC unit to help it run better?
No. 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 AC unit is helpful, but always make sure there’s at least 2–3 feet of clearance around the unit and 5 feet above it to maintain proper airflow.
What temperature should I adjust my thermostat to during a heat wave?
For many homes, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during a heat wave. Set the highest temperature that keeps your family comfortable, and don’t make large thermostat adjustments that force your AC to work harder.
