Extreme summer heat can push any air conditioner to the breaking point. As temperatures in York climb, many families notice higher energy bills, warm areas throughout the home and cooling systems that often run all day without keeping up. 

It’s easy to assume the AC is the one thing that determines 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 explains three simple strategies that can improve comfort and cooling efficiency: boosting airflow in your home, making sure your home has proper insulation and creating shade to reduce heat from the sun. By following these summer AC tips from the pros at Strine's, you’ll keep your house cool during heatwaves. 

Start with Airflow: Help Your AC Work Smarter 

Air conditioners cool air and send it through ductwork to rooms in your home. For that conditioned air to make rooms comfortable, it has to move freely throughout the home. If airflow is blocked, some rooms may feel warmer than others. 

Many people blame their AC for an uncomfortably hot home. In many cases, the AC is often working properly—the real problem is restricted airflow. A clogged air filter, blocked vents and other HVAC issues can all limit airflow. 

Home Airflow Optimization Tips 

Taking steps to improve airflow in your home can enhance comfort, minimize strain on your AC and reduce energy costs. 

  • Swapout dirty air filters. Regular AC air filter replacement helps your HVAC system circulate air more efficiently while improving indoor air quality. 
  • Ensure supply and return vents are free from obstructions. Furniture, rugs and curtains can cause blocked air vents that prevent cooled air from circulating throughout your home. 
  • Open up doors in unused rooms. This 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. During a professional HVAC tune-up, a technician can examine and clean debris-covered blower components that may affect your system’s ability to circulate air. 

Insulation Matters More Than Most Homeowners Realize 

Insulation provides a barrier against the warm air outside your home. As your air conditioner removes heat from inside your home, insulation helps stop heat from moving indoors. Proper insulation enhances comfort, lowers cooling run times and can help extend the life of your HVAC system. 

The attic is one of the primary sources of unwanted heat gain during heatwaves. Proper attic insulation and cooling go hand in hand because attic insulation reduces heat transfer through the roof. Sealing gaps and sealing around doors and windows also help prevent hot outdoor air from sneaking inside. 

If insulation levels are too low or air leaks are present, your air conditioner has to work harder. As a result, many homeowners ask, “Why is my house hot with the AC running?” Often, 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 
  • Air conditioner runningconstantly 

Use Shade to Reduce Heat Gain 

Sunlight shining through windows and heating up your roof and exterior walls raises 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 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 restrict air movement. 

5 Summer AC Tips for Using Shade to Cool Your Home 

  1. Add trees and landscaping strategically. Position 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. 
  2. Install window coverings. Light-colored curtains, cellular shades and thermal drapes limit heat gain from sunlight shining through windows. 
  3. Add solar screens in your home. Solar screens, which are specially designed mesh curtains, used on sun-facing windows help reduce the sun’s heat while still letting in natural light. 
  4. Incorporate exterior shading. Add landscaping and design features like awnings, pergolas, shade sails or exterior shutters to block direct sunlight off windows so it doesn’t heat up your home. 
  5. 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 lower indoor temperatures and reduce the load on your AC. 

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 produce a cooling breeze. 
  • Avoid heat-generating appliances during the hottest part of the day. Run ovens, dryers and dishwashers in the morning or evening to helpreduce indoor heat. 
  • Set thermostat settings. Trytoavoid frequent temperature changes that force your AC to work harder. 
  • Book preventative maintenance. Routine service helps your system perform efficiently before peak cooling season.
  • Watchfor unusual system performance. Address strange noises, weak airflow or inconsistent cooling before they become more expensive repairs. 

The Importance of Knowing When It’s Time to Turn to an HVAC Professional 

DIY 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 air conditioner runs almost constantly, energy bills spike, rooms cool unevenly or your system turns on and off repeatedly, it’s time for an expert evaluation. 

At Strine's, our cooling specialists assess airflow, duct performance, insulation-related comfort concerns and overall system health to pinpoint the underlying cause to help your HVAC system run at its best throughout the summer. 

Keep Your Cool All Summer Long

Frequently Asked Questions About Summer AC Performance 

If your living space remains hot even though your AC is running, the problem isn’t always your AC. Limited airflow, inadequate insulation, inefficient thermostat settings or HVAC system issues can all affect cooling performance and keep cool air from reaching every room.

Absolutely. Trees, landscaping, awnings and window coverings help reduce solar heat gain, helping your home stay cooler. When less heat enters your home means your AC doesn’t have to work as hard to cool your home. This reduces energy, which helps reduce your cooling expenses.

Most households should check their air filter every month during peak cooling season and replace it as necessary. The ideal air filter replacement schedule depends on the filter type, pets, allergies and the amount of time your air conditioner runs.

Yes. Proper home insulation reduces heat transfer into your home, reducing the workload on your AC. Making sure your home has proper insulation levels, especially in your attic or around windows, helps create more consistent indoor temperatures while reducing energy.

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 beneficial, but always make sure there’s at least 2–3 feet of clearance around the unit and 5 feet above it to provide proper airflow.

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. Use the highest temperature that keeps your family comfortable, and avoid large thermostat adjustments that force your air conditioning to work harder.
