Summer in Whatcom and Skagit Counties is a breath of fresh air, but when temperatures climb, our homes can quickly feel like ovens. While we often rely on our cooling systems to do the heavy lifting, running your air conditioner at full blast all day can lead to high energy bills and extra wear on the machine.

Finding a balance between staying chilled and being efficient is the best way to enjoy the season without stress. By using a few simple strategies, you can stay perfectly comfortable while giving your equipment a much-needed break.

If your home is struggling to stay cool or you’re worried about your system making it through the next heatwave, don't wait for a total breakdown.

Manage Your Windows and Natural Light

One of the biggest reasons homes heat up is due to "solar gain." This happens when the sun’s rays shine through your glass windows and turn into heat inside your rooms. In Washington, we love our sunlight, but during a hot afternoon, your windows act like magnifying glasses. By managing how much light enters your home, you can significantly lower the temperature without touching the thermostat.

Keep your blinds or curtains closed on the sunny side of the house during the day. If you have south-facing or west-facing windows, these are the biggest culprits for letting in heat. Heavy or light-colored curtains work best because they reflect the sun away from your living space.

Close curtains by mid-morning: Don't wait until the room is already hot to pull the shades.
Invest in blackout liners: These add an extra layer of insulation against the heat.
Open windows at night: If the temperature drops after sunset, use window fans to pull in that crisp Pacific Northwest air.

Use Fans to Create a Wind-Chill Effect

Fans don’t actually lower a room's temperature, but they do make you feel much cooler. They work by moving air over your skin, which helps your body’s natural cooling process. When you use fans with your air conditioning, you can often set the thermostat a few degrees higher without noticing a difference in comfort.

Remember to turn off the fans when you leave the room. Since fans cool people and not spaces, leaving them running in an empty room is just wasting electricity. Also, check the direction of your ceiling fans to ensure they are helping you effectively.

Counter-clockwise rotation: In the summer, your ceiling fan should spin this way to push a cool breeze straight down.
Box fans for cross-ventilation: Place one fan facing in on the shady side of the house and one facing out on the sunny side to create a breeze.
Keep your skin exposed: Fans work best when they can move air directly across you.

Optimize Your Thermostat Habits

Many homeowners think that setting the temperature to 60°F will cool the house faster, but air conditioners don't work like a gas pedal. They provide a steady stream of cool air until the target temperature is reached. Setting it lower than necessary just keeps the system running for longer, which can lead to "short cycling" or overheating.

Using a programmable thermostat is one of the smartest ways to manage your home's climate. You can set it to be a bit warmer while you are at work and have it start cooling down just before you arrive home. This prevents the system from working hard when nobody is there to enjoy it.

Aim for 78°F: This is often recommended as a great balance between comfort and energy savings.
Avoid big jumps: Try not to change your setting by more than 5-8 degrees at a time.
Check the placement: Ensure your thermostat isn't located near a heat source, such as a lamp or a sunny window, as this can cause it to read the room as hotter than it actually is.

Reduce Heat-Generating Activities Indoors

Your air conditioning has to fight against every heat source inside your home. On a hot day, big appliances can be your worst enemy. Ovens, stoves, and even dishwashers release a significant amount of heat and humidity into your kitchen and living areas.

Try to plan your chores and meals around the heat of the day. Using an outdoor grill or a microwave keeps the heat out of the kitchen. Similarly, running the dryer at night when the air is cooler helps prevent your AC from having to compete with a hot laundry room.

Cook outdoors: Take advantage of the nice weather and use the barbecue.
Switch to LED bulbs: Old incandescent light bulbs get very hot; LEDs stay cool to the touch.
Air-dry your dishes: Turn off the heat-dry setting on your dishwasher to save energy and reduce heat.

Keep Your System Clean and Clear

An air conditioner that is covered in dust or blocked by overgrown bushes has to work twice as hard to do its job. When airflow is restricted, the motor gets hotter, and the cooling coils can even freeze over. Taking a few minutes to check the area around your outdoor unit can save you from a lot of frustration.

Inside the home, check your air vents to make sure they aren't blocked by furniture or rugs. Many people close vents in unused rooms, thinking it saves money, but this can actually increase the pressure in your ductwork and cause leaks. Keeping all vents open ensures the air flows exactly the way the system was designed to handle.

Change filters regularly: A dirty filter is the number one cause of system strain.
Clear the outdoor unit: Keep at least two feet of space clear around your outdoor AC unit.
Vacuum your vents: Don't let pet hair or dust bunnies block the cool air from entering your rooms.

The Importance of Professional Care

While there is a lot you can do on your own, some things require a professional eye. Over time, the refrigerant levels in your system can dip, or the electrical components can wear down. Having a technician review your system ensures it runs at peak efficiency, helping prevent unexpected breakdowns during the hottest weeks of the year.

Regular AC maintenance is like an oil change for your car. It’s a proactive step that helps your system last longer and run quieter. During a visit, a professional can spot small issues—like a loose belt or a dirty coil—before they turn into expensive repairs that leave you sweating.

Schedule early: Try to get your system checked before the first major heatwave hits.
Ask about efficiency: A technician can often give you specific tips based on your home's layout.
Check the ductwork: Professionals can find hidden leaks in your attic or crawlspace that are letting cool air escape.
