Hot summer weather can push even a well-maintained air conditioner to its limits. As temperatures in Winnipeg continue to increase, many families 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 only thing that affects how comfortable your home feels. However, your home’s air circulation, insulation and shade all play a major role in cooling performance.
This guide highlights three practical strategies that can improve comfort and cooling efficiency: increasing airflow in your home, making sure your home has enough insulation and adding shade to reduce heat from the sun. By following these summer AC tips from the pros at Kirkfield Heating & Air Conditioning, you’ll keep your house cool in even the hottest weather.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners lower the temperature of air and send it through ductwork to rooms in your home. For that cool air to keep your home comfortable, it has to move freely throughout the house. Whenever airflow is restricted, some rooms may stay warm.
Many homeowners blame their air conditioning system for a hot home. 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 Improvement Tips
Taking steps to improve airflow in your home can improve comfort, lower strain on your AC and decrease energy costs.
- Replace dirty air filters. Regular AC air filter replacement helps your HVAC system move air more effectively while helping improve indoor air quality.
- Makesure supply and return vents are clear. Furniture, rugs and curtains can create blocked air vents that keep 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 properly.
- Book preventiveAC maintenance services. By doing a professional HVAC tune-up, a technician can check and clean dust-covered blower components that may reduce your system’s ability to circulate air.
Insulation Plays a Bigger Role Than Many Homeowners Think
Insulation serves as a barrier against hot outdoor air. While your air conditioner removes heat from inside your home, insulation helps prevent outdoor heat from entering. High-quality 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 unwanted heat gain during summer. Proper attic insulation and cooling work together because attic insulation reduces heat transfer through the roof. Sealing gaps and sealing around doors and windows also help prevent hot outdoor air from getting inside.
When insulation levels are too low or air leaks let warm air into your home, your AC has to work harder. This often causes 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 Inadequate Home Insulation Levels
- Hot upstairsrooms
- Inconsistent room temperatures
- Higher cooling costs
- AnAC system that runs nonstop
Use Shade to Reduce Heat Gain
Sunlight streaming through windows and heating your roof and exterior walls boosts indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also affect your outdoor air conditioning unit by reducing its ability to release heat efficiently. Adding shade around your property can minimize solar heat gain, improve comfort and reduce 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 limit air movement.
5 Summer AC Tips to Reduce Heat with Outdoor Shade
- Plant trees and landscaping strategically. Use trees to shade your roof, walls, windows and outdoor air conditioning 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.
- Use solar screens in your home. Solar screens, which are specially designed mesh curtains, used on sun-facing windows help block 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 keep direct sunlight off windows so it doesn’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 lower indoor temperatures and ease the load on your cooling system.
Additional Hot Weather Survival Tips
Airflow, insulation and shade can make a big difference, but these AC efficiency tips can further improve comfort during intense summer heat.
- Adjust ceiling fan direction. Rotate ceiling fans counterclockwise to provide a cooling breeze.
- Reduceuse of heat-generating appliances during the hottest part of the day. Run ovens, dryers and dishwashers in the morning or evening to limit indoor heat.
- Manage thermostat settings. Avoid frequent temperature changes that cause your AC to work harder.
- Book preventative maintenance. Regular 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 extensive repairs.
Recognize When It’s Time to Contact an HVAC Professional
Basic AC maintenance and energy-saving cooling strategies can help, but some problems require professional attention. If warm air is coming from your vents, airflow feels weak, your air conditioner runs almost constantly, energy bills increase for no reason, rooms cool unevenly or your system turns on and off repeatedly, you should consider an expert evaluation.

Frequently Asked Questions About Cooling Your Home in Summer
Why is my home still warm even when the air conditioner is operating?
If your home is hot even though your AC is running, the problem isn’t always the air conditioner. Restricted airflow, inadequate insulation, inefficient thermostat settings or HVAC system issues can each reduce cooling performance and stop cool air from reaching every room.
Does outdoor shade really help reduce cooling costs?
It can. Trees, landscaping, awnings and window coverings block solar heat gain, helping your home feel cooler. Less heat entering your home means your AC doesn’t have to work as hard to cool your home. This reduces energy, which helps decrease your cooling expenses.
How often should I change my HVAC air filter during summer?
Most homeowners should check their air filter every month during the peak cooling season and replace it as needed. The ideal air filter replacement schedule depends on the type of filter, pets, allergies and how often your air conditioner runs.
Can insulation {help|make my air conditioner work better?
Absolutely. Proper home insulation reduces heat transfer into your home, reducing strain on your AC. Verifying your home has proper insulation levels, especially in your attic or around windows, helps keep more consistent indoor temperatures while using less energy.
Should I cover my outdoor AC unit during hot weather?
No. You should never cover your outdoor air conditioning unit while it’s operating because the condenser needs unobstructed airflow to release heat. Providing shade for your outdoor air conditioner unit is helpful, but always maintain at least 2–3 feet of clearance around the unit and 5 feet above it to provide 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 an excellent balance of comfort and energy efficiency during a heat wave. Set the highest temperature that keeps your family comfortable, and try not to make large thermostat adjustments that force your air conditioner to work harder.
