Summer heat waves can push any air conditioner to the edge. As temperatures in Auburn and Opelika rise, many homeowners notice higher energy bills, warm areas throughout the home and cooling systems that appear to run all day without keeping up.
You may think the air conditioner is the one thing that determines how comfortable your home feels. In reality, your home’s air circulation, insulation and shade all play an important role in cooling performance.
This guide covers three practical strategies that can improve comfort and cooling efficiency: improving airflow in your home, making sure your home has enough insulation and creating shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Farnell Mechanical, Inc., you’ll keep your house cool in summer.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool the air and send 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 the house. Whenever airflow is restricted, some rooms may stay warm.
Many people blame their air conditioner for poor cooling performance. However, the AC is often working properly—the real problem is poor airflow. Dirty air filters, blocked vents and other HVAC issues can all restrict airflow.
Home Airflow Optimization Strategies
Following these simple steps to boost airflow in your home can enhance comfort, lower strain on your AC and lower energy costs.
- Change dirty air filters. Consistent AC air filter replacement helps your HVAC system circulate air more efficiently while supporting indoor air quality.
- Makesure supply and return vents are unblocked. Furniture, rugs and curtains can lead to blocked air vents that keep cooled air from circulating throughout your home.
- Openinterior doors. This helps air to move more evenly between rooms.
- Move furniture covering registers.Making sure registers are uncovered allows conditioned air to circulate properly.
- Schedule preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can inspect and clean debris-covered blower components that may reduce your system’s ability to circulate air.
Insulation Is More Important Than You Might Expect
Insulation provides a barrier against outdoor heat. Although your AC removes heat from inside your home, insulation helps stop heat from moving indoors. Better insulation enhances comfort, reduces 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 hot weather. Proper attic insulation and cooling work together because attic insulation slows heat transfer through the roof. Proper weatherstripping and sealing around doors and windows also help prevent 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. That often leads homeowners to ask, “Why is my house hot with the AC running?” Often, the real problem is inadequate insulation, and the AC is not the problem.
Signs of Inadequate Home Insulation Levels
- Hot upstairsrooms
- Hotand cold spots
- Higher cooling costs
- Air conditioner runningconstantly
Use Shade to Reduce Heat Gain
Sunlight shining through windows and heating up 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 making it harder to release heat efficiently. Creating shade around your property can limit solar heat gain, improve comfort and decrease summer energy bills. Using trees or other landscaping to shade your air conditioner’s outdoor unit can also help—but never block airflow around the condenser. Keep away fences, enclosures or dense landscaping that limit air movement.
5 Summer AC Tips for Using Shade to Cool Your Home
- Add trees and landscaping strategically. Use trees to shade your roof, walls, windows and outdoor air conditioning equipment. If you’re shading your outdoor AC unit, maintain 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 reduce heat gain from sunlight shining through windows.
- Use 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.
- Strategically use outdoor shade. Use landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to stop direct sunlight off windows so it can’t heat up your home.
- Lower blinds in the afternoon 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 can make a big difference, but these AC efficiency tips can help improve comfort during intense summer heat.
- Change ceiling fan direction. Rotate ceiling fans counterclockwise to create 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 helpreduce indoor heat.
- Manage thermostat settings. Don’t make frequent temperature changes that cause your AC to work harder.
- Schedule preventative maintenance. Routine service helps your system run efficiently before peak cooling season.
- Monitor unusual system performance. Take care of strange noises, weak airflow or inconsistent cooling before they become more expensive repairs.
The Importance of Knowing When It’s Time to Contact an HVAC Professional
Basic AC maintenance and efficiency-focused cooling strategies can help, but some problems need professional attention. When warm air is coming from your vents, airflow feels weak, your air conditioning seems to run constantly, energy bills suddenly increase, 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 Cooling Your Home in Summer
Why is my home still uncomfortable even when the air conditioning is running?
If your living space remains hot even though your AC is running, the problem isn’t always the air conditioner. Restricted airflow, too little insulation, improper thermostat settings or HVAC system issues can each reduce cooling performance and stop cool air from reaching every room.
Does 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 air conditioner doesn’t have to work as hard to cool your home. That saves energy, which helps reduce your cooling expenses.
How often should I check and replace my HVAC air filter throughout the cooling season?
Most households should check their air filter every month during the busiest cooling season and replace it as needed. Your recommended air filter replacement schedule depends on the filter type, pets, allergies and the amount of time your air conditioner runs.
Can insulation {help|make my air conditioner perform better?
Absolutely. Proper home insulation limits heat transfer into your home, reducing strain on your air conditioner. Verifying your home has appropriate 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 help it run better?
Not while it’s running. You should never cover your outdoor air conditioning unit while it’s operating because the condenser needs unrestricted airflow to release heat. Providing shade for your outdoor air conditioning unit is beneficial, but always make sure there’s at least 2–3 feet of clearance around the unit and 5 feet above it to allow proper airflow.
What temperature should I set my thermostat at in the summer?
For most homeowners, 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 avoid large thermostat adjustments that force your AC to work harder.
