Summer Cooling Tips for Portland Residents

Summers in Portland are growing warmer, with more days reaching uncomfortable highs. As climate patterns shift, residents are increasingly looking for ways to stay cool without driving up their energy bills.

Fortunately, there are a number of practical and energy-efficient strategies you can implement to beat the heat. Whether you live in a vintage craftsman or a modern condo, these tips courtesy of Pyramid Heating and Cooling can help you maintain comfort all season long—without breaking the bank.

Maximize Natural Ventilation

One of the simplest and most effective ways to cool your home is to take advantage of the cooler mornings and evenings of the greater Portland area. Open windows on opposite sides of your home to create a cross breeze that naturally flushes out warm air. This works best when the air outside is cooler than inside—typically early in the morning and after sunset.

For added efficiency, consider installing window fans to help draw cool air in and push hot air out. Just remember to close your windows and shades during the heat of the day to trap the cool air inside.

Use Window Treatments Wisely

Up to 30% of unwanted heat comes from windows. Investing in the right window treatments can significantly reduce indoor temperatures. Use blackout curtains or reflective shades, especially on south- and west-facing windows, to block out sunlight during peak hours. Light-colored blinds or thermal curtains can also help reflect rather than absorb solar heat.

If you’re ready for a long-term solution, consider installing solar screens or window films. These options can filter out UV rays while letting in natural light, reducing the greenhouse effect inside your home.

Be Smart With Your HVAC System

Your HVAC system is one of the biggest energy consumers in your home during the summer. To use it more effectively:

• Set your thermostat to 75°F-78°F when you’re home, and increase the temperature by 7-10 degrees when you’re away. A programmable thermostat can automate this for you.
• Change your air filters regularly—ideally every 1-3 months during heavy use. A clean filter ensures efficient airflow and reduces strain on the system.
• Keep doors and windows closed when the AC is on to prevent conditioned air from escaping.
• Schedule a cleaning of your HVAC system’s coils and general tune-up of your air conditioner if you have not done so this year.

If your system is more than 10-15 years old, it might be time to consider a more energy-efficient upgrade. Portland General Electric and Energy Trust of Oregon often offer rebates and incentives for high-efficiency HVAC systems.

Use Fans to Complement AC

Ceiling and portable fans are energy-efficient tools that can make a room feel cooler without lowering the temperature. A ceiling fan used in conjunction with your air conditioner allows you to raise the thermostat by about 4°F without a loss in comfort. Just make sure your ceiling fan is set to spin counterclockwise during the summer to push cool air down.

Box fans placed in windows can also help exhaust hot air out of the home in the evenings, while pedestal or tower fans can help move cool air throughout the house.

Limit Heat-Producing Activities

Appliances like ovens, stoves, dishwashers, and dryers all generate heat. To keep your Portland home cooler:

• Cook outside on the grill, or use the microwave or slow cooker instead of the oven.
• Run the dishwasher and laundry machines at night or early morning.
• Air dry clothes instead of using the dryer.

Switching to LED light bulbs and unplugging unused electronics can also help reduce the amount of heat generated indoors.

Insulate and Seal Your Home

A well-insulated and sealed home keeps cool air in and hot air out. In older homes around the Portland metro area, gaps around doors and windows are common culprits for air leaks. Use weather stripping or caulk to seal these areas. You can also install door sweeps to block heat from creeping in under entryways.

Adding insulation to your attic and walls can make a big difference in your home’s year-round energy performance. While this may be a larger investment, the long-term energy savings and improved comfort often outweigh the initial cost.

Plant for Shade and Cooling

Strategic landscaping can provide long-term cooling benefits. Plant deciduous trees on the south and west sides of your home to block summer sun while allowing light in during the winter. Shrubs or climbing vines placed near walls can also reduce the amount of heat your home absorbs.

Even potted plants on balconies or patios can help cool the surrounding air through a process called transpiration, where plants release moisture into the air.

Consider a Ductless Heat Pump

For homes without central air or spaces that are difficult to cool, a ductless mini split heat pump offers an efficient alternative. These systems are perfect for the climate around Portland, providing heating and cooling. They allow you to control temperatures room by room and are often eligible for rebates and tax credits.

Many homeowners are switching to heat pumps as part of a broader effort to electrify and decarbonize their homes. These systems are especially appealing when paired with solar panels or other energy upgrades.

Stay Hydrated and Dress for the Weather

Finally, don’t forget about personal cooling techniques. Drink plenty of water, wear lightweight and breathable clothing, and take cool showers or use damp washcloths to lower your body temperature. These small habits can reduce your reliance on cooling systems and help you stay comfortable when it’s hot.

Portland-Specific Resources

Take advantage of local programs that can help you stay cool and save energy:

• Energy Trust of Oregon offers free home energy assessments and rebates on insulation, heat pumps, and smart thermostats.
• Portland General Electric (PGE) and Pacific Power provide time-of-use plans and incentives for energy-efficient upgrades.
• Multnomah County Cooling Centers operate during extreme heat events—keep an eye on announcements during heat waves if you need a safe, cool place to go.
