Summer heat waves can push any air conditioner to the edge. As temperatures in Waunakee climb, many families notice rising energy bills, warm areas throughout the home and cooling systems that often run all day without keeping up.
It’s easy to assume the air conditioning is the only thing that affects how comfortable your home feels. In reality, your home’s air circulation, insulation and shade all play a significant role in cooling performance.
This guide highlights three simple strategies that can improve comfort and cooling efficiency: increasing airflow in your home, making sure your home has adequate insulation and creating shade to reduce heat from the sun. Using these summer AC tips from the pros at Home Comfort Heating & Air Conditioning LLC, 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 cool air to keep your home comfortable, it must be able to move freely throughout your home. Whenever airflow is blocked, some rooms may not cool properly.
Many homeowners blame their AC for an uncomfortably hot home. The truth is, the AC is often working properly—the real problem is restricted airflow. A dirty air filter, blocked vents and other HVAC issues can all prevent good airflow.
Home Airflow Optimization Tips
Taking steps to boost airflow in your home can improve comfort, minimize strain on your AC and reduce energy costs.
- Replace dirty air filters. Consistent AC air filter replacement helps your HVAC system increase airflow 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.
- Open up doors in unused rooms. Doing so helps air to move more evenly between rooms.
- Move furniture covering registers.Keeping registers clear allows conditioned air to circulate freely.
- Arrange preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can examine and clean dust-covered blower components that may affect your system’s ability to circulate air.
Insulation Plays a Bigger Role Than Many Homeowners Think
Insulation acts as a barrier against the warm air outside your home. Although your AC removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation increases comfort, lowers cooling run times and can help extend the life of your HVAC system.
The attic is one of the largest sources of solar heat gain during heatwaves. Proper attic insulation and cooling work together because attic insulation reduces heat transfer through the roof. Weatherstripping and sealing around doors and windows also help keep hot outdoor air from getting inside.
When insulation levels are too low or air leaks allow hot air to sneak inside, your air conditioning has to work harder. As a result, many homeowners 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
- Upper floor rooms are always hot
- Inconsistent room temperatures
- Higher cooling costs
- AnAC system that runs nonstop
Use Shade to Reduce Heat Gain
Sunlight shining through windows and heating your roof and exterior walls boosts indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also reduce the efficiency of your outdoor cooling unit by reducing its ability 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 restrict airflow around the condenser. Avoid fences, enclosures or dense landscaping that block 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 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 allow for enough airflow.
- Use window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from sunlight shining through windows.
- Install 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. Maintain blinds or shades closed on west- and south-facing windows during the hottest part of the day to reduce indoor temperatures and ease the load on your AC.
Additional Summer Heat Survival Tips
Airflow, insulation and shade can make a big difference, but these AC efficiency tips can further improve comfort during periods of extreme summer heat.
- Adjust ceiling fan direction. Rotate ceiling fans counterclockwise to create 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 helpreduce indoor heat.
- Manage thermostat settings. Don’t make frequent temperature changes that make your AC to work harder.
- Schedule preventative maintenance. Regular service helps your system operate 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 Call an HVAC Professional
At-home AC maintenance and efficiency-focused cooling strategies can help, but some problems need professional attention.

Frequently Asked Questions About Summer Air Conditioner Efficiency
Why is my home still uncomfortable even when the AC is running?
If your living space remains hot even though your AC is running, the problem isn’t always your air conditioner. Poor airflow, too little insulation, inefficient thermostat settings or HVAC system issues can all reduce cooling performance and stop cool air from reaching every room.
Does shade really help lower cooling costs?
It can. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home remain cooler. When less heat enters your home means your air conditioning doesn’t have to work as hard to cool your home. That saves energy, which helps decrease 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. The ideal air filter replacement schedule depends on the air filter you use, pets, allergies and how frequently your air conditioner runs.
Can insulation {help|make my air conditioner run more efficiently?
It can. Proper home insulation limits heat transfer into your home, reducing the workload on your air conditioner. Ensuring your home has adequate insulation levels, especially in your attic or around windows, helps create more consistent indoor temperatures while using less 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. Adding 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 maintain proper airflow.
What temperature should I set my thermostat at during hot weather?
For most homeowners, setting the thermostat around 78 degrees when you’re home offers a good balance of comfort and energy efficiency during a heat wave. Use the highest temperature that keeps you comfortable, and try not to make large thermostat adjustments that force your air conditioning to work harder.
