Summer heat waves can push any air conditioner to its limits. As temperatures in Smyrna continue to increase, many homeowners notice rising energy bills, hot spots throughout the home and cooling systems that appear to run all day without keeping up.
People often think the air conditioning is the only thing that affects how comfortable your home feels. The fact is, your home’s airflow, insulation and shade all play an important role in cooling performance.
This guide covers three simple strategies that can improve comfort and cooling efficiency: boosting airflow in your home, making sure your home has adequate insulation and creating shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Fletcher Plumbing, Heating & AC, you’ll keep your house cool in summer.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners lower the temperature of air and distribute it through ductwork to the rooms in your home. For that cooled air to make rooms comfortable, it must be able to move freely throughout your home. Whenever airflow is blocked, some rooms may feel warmer than others.
It’s common for homeowners to blame their air conditioner for a hot home. The truth is, the AC is often working just fine—the real problem is restricted airflow. Dirty air filters, blocked vents and other HVAC issues can all inhibit airflow.
Home Airflow Optimization Tips
Taking steps to boost airflow in your home can increase comfort, minimize strain on your AC and lower energy costs.
- Swapout dirty air filters. Consistent AC air filter replacement helps your HVAC system increase airflow while helping improve indoor air quality.
- Ensure supply and return vents are free from obstructions. Furniture, rugs and curtains can lead to blocked air vents that keep cooled air from circulating throughout your home.
- Open up doors in unused rooms. This helps air to move more evenly between rooms.
- Move furniture covering registers.Keeping registers clear allows conditioned air to circulate properly.
- Arrange preventiveAC maintenance services. During a professional HVAC tune-up, a technician can inspect and clean debris-covered blower components that may affect 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. As your air conditioner removes heat from inside your home, insulation helps stop heat from moving indoors. Better insulation enhances comfort, lowers cooling run times and can help extend the life of your HVAC system.
The attic is one of the largest sources of unwanted heat gain during heatwaves. Proper attic insulation and cooling are closely connected because attic insulation limits heat transfer through the roof. 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 let warm air into your home, your air conditioning has to work harder. That often leads 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 Poor Home Insulation Levels
- Hot upstairsrooms
- Inconsistent room temperatures
- High utilitybills
- AnAC system that runs nonstop
Use Shade to Help Lower Cooling Costs
Sunlight streaming through windows and heating up your roof and exterior walls raises indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also impact your outdoor AC unit by making it harder 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 restrict air movement.
5 Summer AC Tips to Reduce Heat with Outdoor Shade
- Plan trees and landscaping strategically. Use 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 maintain enough airflow.
- Use window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from sunlight shining through windows.
- Add solar screens in your home. Solar screens, which are specially designed mesh curtains, used on sun-facing windows help limit the sun’s heat while still providing 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 doesn’t heat up your home.
- Keep blinds closed during high heat. Shut blinds or shades closed on west- and south-facing windows during the hottest part of the day to reduce indoor temperatures and reduce the load on your air conditioning system.
Additional Heat-Wave Survival Tips
Airflow, insulation and shade all make a big difference, but these AC efficiency tips can help improve comfort during intense summer heat.
- Adjust ceiling fan direction. Operate ceiling fans counterclockwise to provide a cooling breeze.
- Avoid heat-generating appliances during the hottest part of the day. Use ovens, dryers and dishwashers in the morning or evening to helpreduce indoor heat.
- Manage thermostat settings. Avoid frequent temperature changes that make your AC to work harder.
- Arrange preventative maintenance. Professional service helps your system operate 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
At-home AC maintenance and energy-saving cooling strategies can help, but some problems call for professional attention. When warm air is coming from your vents, airflow feels weak, your air conditioning 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.

Frequently Asked Questions About Summer Air Conditioner Efficiency
Why is my home still warm even when the air conditioning is operating?
When your house stays hot even though your AC is running, the problem isn’t always your air conditioner. Restricted airflow, inadequate insulation, incorrect thermostat settings or HVAC system issues can all affect cooling performance and stop cool air from reaching every room.
Does adding shade really help reduce cooling costs?
Absolutely. Trees, landscaping, awnings and window coverings help reduce solar heat gain, helping your home stay cooler. When less heat enters your home means your AC doesn’t have to work as hard to cool your home. That uses less energy, which helps reduce your cooling expenses.
How often should I change my HVAC air filter in the summer?
Most homeowners should check their air filter every month during the busiest cooling season and replace it as needed. The best 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 run more efficiently?
Yes. Proper home insulation limits heat transfer into your home, reducing strain on your air conditioner. Ensuring your home has adequate insulation levels, especially in your attic or around windows, helps keep more consistent indoor temperatures while using less energy.
Should I put a cover over my outdoor AC unit during hot weather?
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. Providing shade for your outdoor air conditioner 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 in the summer?
For many homes, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during very hot weather. Set the highest temperature that keeps you comfortable, and don’t make large thermostat adjustments that force your air conditioner to work harder.
