Summer heat waves can push even a well-maintained air conditioner to its limits. As temperatures in Bend rise, many homeowners notice increased energy bills, hot spots throughout the home and cooling systems that often run all day without keeping up.
People often think the air conditioner alone determines how comfortable your home feels. However, your home’s airflow, insulation and shade all play an important role in cooling performance.
This guide highlights three simple 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. When you follow these summer AC tips from the pros at Tri County Climate Control LLC, you’ll keep your house cool in even the hottest weather.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool air and move it through ductwork to the rooms in your home. For that cool air to cool every room effectively, it must be able to move freely throughout the house. Whenever airflow is restricted, some rooms may feel warmer than others.
Many people blame their AC for poor cooling performance. However, the AC is often working just fine—the real problem is restricted airflow. A dirty air filter, blocked vents and other HVAC issues can all inhibit airflow.
Home Airflow Improvement Checklist
Following these simple steps to improve airflow in your home can increase comfort, reduce strain on your AC and lower energy costs.
- Swapout dirty air filters. Routine AC air filter replacement helps your HVAC system circulate air more efficiently while improving indoor air quality.
- Makesure 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.
- Move furniture covering registers.Keeping registers clear allows conditioned air to circulate more easily.
- Book preventiveAC maintenance services. During 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 acts as a barrier against the warm air outside your home. Although your air conditioner removes heat from inside your home, insulation helps keep that heat from getting inside. Proper insulation improves comfort, decreases 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. Weatherstripping and sealing around doors and windows also help prevent hot outdoor air from getting inside.
Whenever insulation levels are too low or air leaks are present, your AC has to work harder. This often causes homeowners to ask, “Why is my house hot with the AC running?” Often, insufficient insulation—not the air conditioner—is the problem.
Signs of Low Home Insulation Levels
- Hot upstairsrooms
- Uneventemperatures
- Higher cooling costs
- AnAC system that runs nonstop
Use Shade to Keep Your Home Cooler
Sunlight shining through windows and heating up your roof and exterior walls increases indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also affect your outdoor AC 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 block airflow around the condenser. Avoid fences, enclosures or dense landscaping that block air movement.
5 Summer AC Tips for Keeping Your Home Cooler with Shade
- Plant trees and landscaping strategically. Position trees to shade your roof, walls, windows and outdoor cooling equipment. When shading your outdoor AC unit, keep at least 2–3 feet of clearance on all sides and 5 feet above the unit to ensure it receives enough airflow.
- Add window coverings. Light-colored curtains, cellular shades and thermal drapes help 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 providing natural light.
- Incorporate outdoor shade. Add landscaping and design features like 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 lighten the load on your air conditioning system.
Additional Summer Heat Survival Tips
Airflow, insulation and shade all make a big difference, but these AC efficiency tips can further improve comfort during periods of extreme summer heat.
- Settheappropriate ceiling fan direction. Operate ceiling fans counterclockwise to produce 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.
- Set thermostat settings. Avoid frequent temperature changes that make your AC to work harder.
- Schedule preventative maintenance. Routine 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 Contact an HVAC Professional
DIY 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 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 Air Conditioner Efficiency
Why is my home still uncomfortable even when the AC is on?
When your house stays hot even though your AC is running, the problem isn’t always your air conditioner. Poor airflow, too little insulation, improper thermostat settings or HVAC system issues can each reduce cooling performance and prevent cool air from reaching every room.
Does shade really help reduce cooling costs?
Absolutely. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home feel cooler. Reducing the amount of heat entering your home means your AC doesn’t have to work as hard to cool your home. This reduces energy, which helps reduce your cooling expenses.
How often should I change my HVAC air filter in the 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 the amount of time 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 proper insulation levels, especially in your attic or around windows, helps maintain more consistent indoor temperatures while reducing energy.
Should I cover my outdoor AC unit to help it run better?
Not while it’s running. You should never cover your outdoor AC unit while it’s operating because the condenser needs unobstructed airflow to release heat. Providing shade for your outdoor air conditioner unit is a good idea, but always keep at least 2–3 feet of clearance around the unit and 5 feet above it to allow proper airflow.
What temperature should I keep my thermostat at in the summer?
In many households, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during very hot weather. Use the highest temperature that keeps you comfortable, and try not to make large thermostat adjustments that force your air conditioner to work harder.
