Summer heat waves can push even a well-maintained air conditioner to its limits. As temperatures in Redding continue to increase, many families notice higher energy bills, warm areas throughout the home and cooling systems that seem to run all day without keeping up.
People often think the air conditioning is the one thing that determines how comfortable your home feels. However, your home’s airflow, insulation and shade all play a major role in cooling performance.
This guide highlights three simple strategies that can improve comfort and cooling efficiency: boosting airflow in your home, making sure your home has enough insulation and creating shade to reduce heat from the sun. Using these summer AC tips from the pros at Allianz Heating & Air, you’ll keep your house cool during heatwaves.
Start with Airflow: Make Your Air Conditioner Work More Efficiently
Air conditioners cool the air and send it through ductwork to rooms in your home. For that cool air to make rooms comfortable, 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 an uncomfortably hot home. However, the AC is often working properly—the real problem is limited airflow. A clogged air filter, blocked vents and other HVAC issues can all restrict airflow.
Home Airflow Optimization Tips
Following these simple steps to boost airflow in your home can increase comfort, reduce strain on your AC and reduce energy costs.
- Replace dirty air filters. Routine AC air filter replacement helps your HVAC system circulate air more efficiently while helping improve indoor air quality.
- Check that supply and return vents are free from obstructions. Furniture, rugs and curtains can cause blocked air vents that prevent cooled air from circulating throughout your home.
- Keep interior doors open. This helps air to move more evenly between rooms.
- Reposition furniture covering registers.Making sure registers are free of obstructions allows conditioned air to circulate properly.
- Arrange preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can examine and clean dust-covered blower components that may limit your system’s ability to circulate air.
Insulation Is More Important Than You Might Expect
Insulation serves as a barrier against the warm air outside your home. 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 solar heat gain during hot weather. Proper attic insulation and cooling are closely connected because attic insulation reduces heat transfer through the roof. 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 AC has to work harder. This often causes homeowners to ask, “Why is my house hot with the AC running?” Often, home insulation levels—not the air conditioner—are the problem.
Signs of Low Home Insulation Levels
- Hot upstairsrooms
- Hotand cold spots
- Risingenergy bills
- An air conditioner that rarely shuts off
Use Shade to Keep Your Home Cooler
Sunlight coming through windows and heating your roof and exterior walls boosts 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 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 obstruct airflow around the condenser. Avoid fences, enclosures or dense landscaping that limit air movement.
5 Summer AC Tips for Keeping Your Home Cooler with Shade
- 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 allow for enough airflow.
- Add window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from direct sunlight coming through windows.
- Add 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.
- Strategically use exterior shading. 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.
- Close your blinds during the afternoon. Maintain blinds or shades closed on west- and south-facing windows during the hottest part of the day to help reduce indoor temperatures and lighten the load on your air conditioning system.
Additional Hot Weather Survival Tips
Airflow, insulation and shade all make a big difference, but these AC efficiency tips can further improve comfort during intense summer heat.
- Adjust 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 limit indoor heat.
- Adjust thermostat settings. Avoid frequent temperature changes that make your AC to work harder.
- Arrange preventative maintenance. Regular service helps your system perform efficiently before peak cooling season.
- Monitor unusual system performance. Address strange noises, weak airflow or inconsistent cooling before they become larger repairs.
Recognize When It’s Time to Turn to an HVAC Professional
Basic AC maintenance and energy-saving cooling strategies can help, but some problems call for professional attention. If warm air is coming from your vents, airflow feels weak, your air conditioner runs almost constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, it’s a good idea to schedule an expert evaluation.
At Allianz Heating & Air, 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 Air Conditioner Efficiency
Why is my house still warm even when the air conditioning is running?
If your home is hot even though your AC is running, the problem isn’t always your AC. 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 lower cooling costs?
Yes. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home feel cooler. Less heat entering your home means your cooling system 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 during summer?
Most households should check their air filter every month during peak cooling season and replace it as needed. Your recommended air filter replacement schedule depends on the filter type, pets, allergies and how frequently your air conditioner runs.
Can insulation {help|make my air conditioner perform better?
Absolutely. Proper home insulation reduces heat transfer into your home, reducing strain on your AC. Making sure your home has adequate insulation levels, especially in your attic or around windows, helps create more consistent indoor temperatures while reducing energy.
Should I cover my outdoor AC unit to help it run better?
You shouldn’t. 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 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.
What temperature should I keep my thermostat at when it’s hot outside?
For most homeowners, setting the thermostat around 78 degrees when you’re home offers the right balance of comfort and energy efficiency during very hot weather. Set the highest temperature that keeps your family comfortable, and try not to make large thermostat adjustments that force your air conditioning to work harder.
