AAA Heating & Cooling

What this contractor is listed for

During a summer heat wave, choosing the right AC setting can make a big difference in both comfort and energy efficiency. Most HVAC professionals recommend setting your thermostat to around 78°F when you’re home. This temperature helps keep your home cool while preventing your air conditioner from overworking during periods of extreme heat. If you’re away from home for several hours, you can raise the temperature by a few degrees (usually around 80–82°F) to reduce energy use. When you return, avoid drastically lowering the thermostat, as this won’t cool your home faster and can strain your system. Instead, allow your air conditioner to bring the temperature down gradually. During a heat wave, it’s also helpful to keep blinds or curtains closed during the hottest parts of the day and avoid using heat-generating appliances like ovens or dryers whenever possible. Ceiling fans can also help circulate cool air and make your home feel more comfortable without lowering the thermostat. For homeowners in Portland, keeping your air conditioning system well-maintained is especially important during extreme temperatures. Regular tune-ups and clean filters help your system run efficiently and keep your home cool when you need it most.
