Hot summer weather can push any air conditioner to the breaking point. As temperatures in Elk River rise, it’s common to 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 AC alone determines how comfortable your home feels. However, your home’s air circulation, insulation and shade all play a major role in cooling performance.
This guide covers three effective strategies that can enhance comfort and cooling efficiency: improving airflow in your home, making sure your home has enough insulation and using shade to reduce heat from the sun. When you follow these summer AC tips from the pros at Home Comfort Heating & Air, you’ll keep your house cool during heatwaves.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool the air and distribute it through ductwork to every room in your home. For that cool air to make rooms comfortable, it must move freely throughout your home. When airflow is blocked, some rooms may not cool properly.
Many people blame their AC for poor cooling performance. The truth is, the AC is often working fine—the real problem is limited airflow. Dirty air filters, blocked vents and other HVAC issues can all reduce airflow.
Home Airflow Optimization Tips
Following these simple steps to boost airflow in your home can enhance comfort, minimize strain on your AC and lower 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 clear. Furniture, rugs and curtains can cause blocked air vents that keep cooled air from circulating throughout your home.
- Keep interior doors open. This allows air to move more evenly between rooms.
- Reposition furniture covering registers.Making sure registers are free of obstructions allows conditioned air to circulate freely.
- Book preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can check and clean dirty 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. While your air conditioning removes heat from inside your home, insulation helps prevent outdoor heat from entering. Better insulation improves comfort, lowers cooling run times and can help maximize the life of your HVAC system.
The attic is one of the primary sources of solar heat gain during hot weather. Proper attic insulation and cooling work together because attic insulation reduces heat transfer through the roof. Proper weatherstripping and sealing around doors and windows also help stop hot outdoor air from getting inside.
If insulation levels are too low or air leaks are present, your air conditioning has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” Often, insufficient insulation—not the air conditioner—is the problem.
Signs of Low Home Insulation Levels

- Uneventemperatures
- High utilitybills
- Air conditioner runningconstantly
Use Shade to Reduce Heat Gain
Sunlight coming through windows and warming 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 AC unit by reducing its ability to release heat efficiently. Using shade around your property can limit solar heat gain, improve comfort and reduce summer energy bills. Shading 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 for Using Shade to Cool Your Home
- Plant trees and landscaping strategically. Use trees to shade your roof, walls, windows and outdoor AC 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.
- Use window coverings. Light-colored curtains, cellular shades and thermal drapes help reduce heat gain from direct sunlight coming through windows.
- Add 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 letting in natural light.
- Incorporate outdoor shade. Add landscaping and design features such as awnings, pergolas, shade sails or exterior shutters to block 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 help reduce indoor temperatures and ease 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 further improve comfort during extreme summer heat.
- Change ceiling fan direction. Run ceiling fans counterclockwise to produce 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 reduce indoor heat.
- Set thermostat settings. Trytoavoid frequent temperature changes that force your AC to work harder.
- Book preventative maintenance. Professional service helps your system operate efficiently before peak cooling season.
- Watchfor unusual system performance. Address 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 efficiency-focused cooling strategies can help, but some problems require professional attention. When warm air is coming from your vents, airflow feels weak, your air conditioner 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 Cooling Your Home in Summer
Why is my house still hot even when the AC is operating?
If your living space remains hot even though your AC is running, the problem isn’t always your AC. Limited airflow, inadequate insulation, incorrect thermostat settings or HVAC system issues can each reduce cooling performance and prevent cool air from reaching every room.
Does outdoor shade really help reduce cooling costs?
It can. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home stay cooler. When less heat enters your home means your air conditioning 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 change my HVAC air filter in the summer?
Most homeowners should check their air filter every month during the peak cooling season and replace it as needed. The best air filter replacement schedule depends on the filter type, pets, allergies and how often 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. Verifying your home has proper insulation levels, especially in your attic or around windows, helps maintain more consistent indoor temperatures while using less energy.
Should I cover my outdoor AC unit to keep it cooler?
You shouldn’t. 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 AC unit is beneficial, but always maintain at least 2–3 feet of clearance around the unit and 5 feet above it to allow proper airflow.
What temperature should I keep my thermostat at during a heat wave?
For many homes, setting the thermostat around 78 degrees when you’re home offers an excellent balance of comfort and energy efficiency during a heat wave. Use the highest temperature that keeps you comfortable, and avoid large thermostat adjustments that force your AC to work harder.
