Summer heat waves can push any air conditioner to the breaking point. As temperatures in Greater Richmond climb, it’s common to notice higher energy bills, uneven temperatures throughout the home and cooling systems that appear to run all day without keeping up.
You may think the air conditioner alone determines how comfortable your home feels. In reality, your home’s airflow, insulation and shade all play a major role in cooling performance.
This guide covers three practical strategies that can improve comfort and cooling efficiency: boosting airflow in your home, making sure your home has enough insulation and using shade to reduce heat from the sun. Using these summer AC tips from the pros at Herman Allen Plumbing, Heating & Cooling, you’ll keep your house cool during heatwaves.
Start with Airflow: Improve Airflow for Better Cooling
Air conditioners cool air and send it through ductwork to every room in your home. For that conditioned air to cool every room effectively, it must move freely throughout the house. When airflow is blocked, some rooms may not cool properly.
It’s common for homeowners to blame their air conditioner for an uncomfortably hot home. However, the AC is often working fine—the real problem is restricted airflow. A clogged air filter, blocked vents and other HVAC issues can all inhibit airflow.
Home Airflow Improvement Strategies
Taking steps to boost airflow in your home can improve comfort, lower strain on your AC and reduce energy costs.
- Change dirty air filters. Consistent AC air filter replacement helps your HVAC system move air more effectively while helping improve indoor air quality.
- Makesure supply and return vents are free from obstructions. Furniture, rugs and curtains can create blocked air vents that prevent 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 uncovered allows conditioned air to circulate more easily.
- Schedule preventiveAC maintenance services. As part of a professional HVAC tune-up, a technician can check 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 serves as a barrier against outdoor heat. Although your air conditioning removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation increases comfort, decreases cooling run times and can help maximize the life of your HVAC system.
The attic is one of the biggest 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 prevent hot outdoor air from getting inside.
If insulation levels are too low or air leaks are present, your AC has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” In many cases, home insulation levels—not the air conditioner—are the problem.
Signs of Low Home Insulation Levels
- Hot upstairsrooms
- Inconsistent room temperatures
- High utilitybills
- Air conditioner runningconstantly
Use Shade to Reduce Heat Gain
Sunlight streaming through windows and heating your roof and exterior walls increases indoor temperatures, forcing your air conditioner to work harder.
Direct sunlight can also reduce the efficiency of your outdoor AC unit by making it more difficult 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 to Reduce Heat with Outdoor Shade
- Plant trees and landscaping strategically. Position trees to shade your roof, walls, windows and outdoor air conditioning equipment. While providing shade for 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 reduce heat gain from sunlight shining through windows.
- Add 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 allowing in natural light.
- Incorporate outdoor shade. Add 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.
- Keep blinds closed during high 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 ease the load on your cooling system.
Additional Heat-Wave Survival Tips
Airflow, insulation and shade all make a big difference, but these AC efficiency tips can further improve comfort during intense summer heat.
- Settheappropriate ceiling fan direction. Operate ceiling fans counterclockwise to provide 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 limit indoor heat.
- Manage thermostat settings. Avoid frequent temperature changes that cause your AC to work harder.
- Book preventative maintenance. Routine service helps your system run efficiently before peak cooling season.
- Pay attention to unusual system performance. Address strange noises, weak airflow or inconsistent cooling before they become more expensive repairs.
Recognize When It’s Time to Contact an HVAC Professional
Basic AC maintenance and efficiency-focused cooling strategies can help, but some problems call for professional attention. If warm air is coming from your vents, airflow feels weak, your AC runs almost constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, you should consider an expert evaluation.

Frequently Asked Questions About Summer Air Conditioner Efficiency
Why is my home still hot even when the air conditioner is running?
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 all reduce cooling performance and stop cool air from reaching every room.
Does adding shade really help lower cooling costs?
Yes. Trees, landscaping, awnings and window coverings reduce solar heat gain, helping your home remain cooler. When less heat enters your home means your air conditioner doesn’t have to work as hard to cool your home. This reduces energy, which helps reduce your cooling expenses.
How often should I replace my HVAC air filter in the summer?
Most homeowners should check their air filter every month during peak cooling season and replace it as needed. The best 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 perform better?
Absolutely. Proper home insulation limits heat transfer into your home, reducing strain on your air conditioning. Making sure your home has adequate 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 keep it cooler?
Not while it’s running. You should never cover your outdoor AC unit while it’s running because the condenser needs unobstructed airflow to release heat. Providing shade for your outdoor air conditioning unit is beneficial, but always keep at least 2–3 feet of clearance around the unit and 5 feet above it to maintain proper airflow.
What temperature should I keep my thermostat at when it’s hot outside?
For most homeowners, setting the thermostat around 78 degrees when you’re home offers the right balance of comfort and energy efficiency during a heat wave. Choose the highest temperature that keeps your family comfortable, and don’t make large thermostat adjustments that force your AC to work harder.
