Summer heat waves can push even a well-maintained air conditioner to the breaking point. As temperatures in Columbus continue to increase, it’s common to notice higher energy bills, hot spots throughout the home and cooling systems that often run all day without keeping up.
You may think the air conditioning is the only thing that affects how comfortable your home feels. In reality, your home’s airflow, insulation and shade all play an important role in cooling performance.
This guide explains three simple strategies that can improve comfort and cooling efficiency: increasing airflow in your home, making sure your home has adequate insulation and using shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Classic Air, you’ll keep your house cool during heatwaves.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool air and move it through ductwork to every room in your home. For that cooled air to keep your home comfortable, it must be able to move freely throughout your home. If airflow is blocked, some rooms may not cool properly.
It’s common for homeowners to blame their AC for an uncomfortably hot home. However, the AC is often working properly—the real problem is restricted airflow. A clogged air filter, blocked vents and other HVAC issues can all prevent good airflow.
Home Airflow Improvement Tips
Taking these easy steps to improve airflow in your home can improve comfort, lower strain on your AC and reduce energy costs.
- Change dirty air filters. Routine AC air filter replacement helps your HVAC system move air more effectively while supporting indoor air quality.
- Ensure supply and return vents are free from obstructions. Furniture, rugs and curtains can lead to blocked air vents that stop cooled air from circulating throughout your home.
- Keep interior doors open. Doing so helps air to move more evenly between rooms.
- Relocate furniture covering registers.Making sure registers are uncovered allows conditioned air to circulate freely.
- Arrange preventiveAC maintenance services. During a professional HVAC tune-up, a technician can check and clean debris-covered blower components that may affect your system’s ability to circulate air.
Insulation Plays a Bigger Role Than Many Homeowners Think
Insulation serves as a barrier against outdoor heat. As your AC removes heat from inside your home, insulation helps prevent outdoor heat from entering. Better insulation improves comfort, lowers cooling run times and can help increase 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 are closely connected because attic insulation slows heat transfer through the roof. Weatherstripping and sealing around doors and windows also help keep hot outdoor air from getting inside.
If insulation levels are too low or air leaks let warm air into your home, your air conditioner has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” Frequently, the real problem is inadequate insulation, and the AC is not the problem.
Signs of Poor Home Insulation Levels
- Upper floor rooms are always hot
- Inconsistent room temperatures
- High utilitybills
- An air conditioner that rarely shuts off
Use Shade to Reduce Heat Gain
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 AC unit by making it harder to release heat efficiently. Adding shade around your property can minimize solar heat gain, improve comfort and lower summer energy bills. Using trees or other landscaping to shade your air conditioner’s outdoor unit can also help—but never restrict airflow around the condenser. Don’t install fences, enclosures or dense landscaping that limit air movement.
5 Summer AC Tips for Using Shade to Cool Your Home
- Plan trees and landscaping strategically. Place trees to shade your roof, walls, windows and outdoor cooling equipment. When shading your outdoor AC unit, maintain at least 2–3 feet of clearance on all sides and 5 feet above the unit to ensure it receives enough airflow.
- Install window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from sun streaming 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 block direct sunlight off windows so it can’t heat up your home.
- Lower blinds in the afternoon heat. Maintain 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 Summer Heat Survival Tips
Airflow, insulation and shade can make a big difference, but these AC efficiency tips can help improve comfort during periods of extreme summer heat.
- Change ceiling fan direction. Run ceiling fans counterclockwise to produce a cooling breeze.
- Avoid heat-generating appliances during the hottest part of the day. Operate ovens, dryers and dishwashers in the morning or evening to helpreduce indoor heat.
- Adjust thermostat settings. Avoid frequent temperature changes that cause 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. Take care of strange noises, weak airflow or inconsistent cooling before they become larger repairs.
Know When It’s Time to Turn to an HVAC Professional
At-home AC maintenance and energy-saving cooling strategies can help, but some problems call for professional attention. If warm air is coming from your vents, airflow feels weak, your air conditioning 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.
At Classic Air, our cooling specialists evaluate airflow, duct performance, insulation-related comfort concerns and overall system health to determine the real cause to help your HVAC system run at its best throughout the summer.

Frequently Asked Questions About Summer AC Performance
Why is my home still uncomfortable even when the air conditioner is running?
If your home is hot even though your AC is running, the problem isn’t always the AC. Poor airflow, inadequate insulation, improper thermostat settings or HVAC system issues can all reduce cooling performance and stop cool air from reaching every room.
Does outdoor shade really help lower cooling costs?
Yes. Trees, landscaping, awnings and window coverings block solar heat gain, helping your home feel cooler. Reducing the amount of heat entering your home means your cooling system doesn’t have to work as hard to cool your home. That uses less energy, which can lower your cooling expenses.
How often should I replace my HVAC air filter throughout the cooling season?
For most homes, homeowners should check their air filter every month during the peak cooling season and replace it as needed. Your recommended 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?
Yes. Proper home insulation limits heat transfer into your home, reducing strain on your AC. Making sure your home has appropriate insulation levels, especially in your attic or around windows, helps keep more consistent indoor temperatures while lowering energy.
Should I cover up 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 running because the condenser needs unrestricted airflow to release heat. Adding shade for your outdoor air conditioning 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 allow proper airflow.
What temperature should I set my thermostat at when it’s hot outside?
For many homes, 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 don’t make large thermostat adjustments that force your air conditioning to work harder.
