Summer heat waves can push any air conditioner to the edge. As temperatures in Northridge climb, many families notice rising energy bills, warm areas 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 highlights three practical strategies that can increase comfort and cooling efficiency: boosting airflow in your home, making sure your home has adequate insulation and adding shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Enertek Air Conditioning & Heating, you’ll keep your house cool during heatwaves.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool air and send it through ductwork to every room in your home. For that cooled air to keep your home comfortable, it must move freely throughout the home. If airflow is restricted, some rooms may stay warm.
Many people blame their air conditioning system for poor cooling performance. However, the AC is often working just fine—the real problem is restricted airflow. Dirty air filters, blocked vents and other HVAC issues can all reduce airflow.
Home Airflow Optimization Tips
Taking these easy steps to improve airflow in your home can enhance comfort, minimize strain on your AC and reduce energy costs.
- Change dirty air filters. Regular 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 create blocked air vents that stop cooled air from circulating throughout your home.
- Openinterior doors. This helps air to move more evenly between rooms.
- Move furniture covering registers.Keeping registers clear allows conditioned air to circulate freely.
- Book preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can examine and clean debris-covered blower components that may limit your system’s ability to circulate air.
Insulation Matters More Than Most Homeowners Realize
Insulation acts as a barrier against hot outdoor air. Although your AC removes heat from inside your home, insulation helps keep that heat from getting inside. High-quality insulation increases comfort, decreases cooling run times and can help maximize the life of your HVAC system.
The attic is one of the largest 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. Sealing gaps and sealing around doors and windows also help stop hot outdoor air from entering your home.
If 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?” In many cases, insufficient insulation—not the air conditioner—is the problem.
Signs of Poor Home Insulation Levels
- Hot upstairsrooms
- Uneventemperatures
- Risingenergy bills
- AnAC system that runs nonstop
Use Shade to Keep Your Home Cooler
Sunlight shining through windows and heating your roof and exterior walls raises indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also affect your outdoor cooling unit by reducing its ability to release heat efficiently. Adding shade around your property can limit solar heat gain, improve comfort and lower summer energy bills. Shading 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 restrict air movement.
5 Summer AC Tips to Reduce Heat with Outdoor Shade
- Plant trees and landscaping strategically. Place trees to shade your roof, walls, windows and outdoor air conditioning equipment. While providing shade for 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.
- Use window coverings. Light-colored curtains, cellular shades and thermal drapes reduce heat gain from sunlight shining through windows.
- Add solar screens in your home. Solar screens, which are specially designed mesh curtains, placed on sun-facing windows help limit the sun’s heat while still letting in natural light.
- Strategically use exterior shading. Add landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to block direct sunlight off windows before it enters 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 reduce indoor temperatures and lighten the load on your air conditioner.
Additional Summer Heat Survival Tips
Airflow, insulation and shade make a big difference, but these AC efficiency tips can help improve comfort during periods of extreme 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. Operate ovens, dryers and dishwashers in the morning or evening to limit indoor heat.
- Adjust thermostat settings. Don’t make frequent temperature changes that force 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 more expensive repairs.
Know When It’s Time to Turn to an HVAC Professional
Basic 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 AC 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.

Frequently Asked Questions About Summer AC Performance
Why is my home still warm even when the air conditioner is on?
When your house stays hot even though your AC is running, the problem isn’t always your AC. Restricted airflow, inadequate insulation, incorrect thermostat settings or HVAC system issues can all affect cooling performance and prevent cool air from reaching every room.
Does outdoor shade really help reduce cooling costs?
It can. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home stay 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 can lower your cooling expenses.
How often should I change my HVAC air filter during summer?
Most households should check their air filter every month during peak cooling season and replace it as necessary. The ideal air filter replacement schedule depends on the type of filter, pets, allergies and how frequently your air conditioner runs.
Can insulation {help|make my air conditioner work better?
It can. 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 lowering energy.
Should I put a cover over my outdoor AC unit to keep it cooler?
You shouldn’t. You should never cover your outdoor air conditioning unit while it’s operating because the condenser needs unrestricted airflow to release heat. Adding shade for your outdoor AC unit is helpful, but always keep at least 2–3 feet of clearance around the unit and 5 feet above it to maintain 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 very hot weather. Choose the highest temperature that keeps you comfortable, and don’t make large thermostat adjustments that force your air conditioning to work harder.
