Everything You Need To Know About Cooling Your Home

Summer may be lazy and hazy, but in many areas of the country, it’s also a time of sweating and sweltering in scorching temperatures. To cope, homeowners employ a variety of methods to ensure a steady supply of cool, fresh air.

These cooling solutions include a wide variety of fans and in-home ventilation systems as well as some tried-and-true techniques from the days before air conditioning. Here’s how to keep your whole home cool this season.

The advent of air conditioners

By far the most common form of cooling in the United States is air conditioning, which can be found in more than 88 percent of new single-family homes constructed today. Keeping the house comfortable this way, however, can be a costly investment in terms of both equipment and energy use — we’re talking an average $ 400 household electric bill from June to August. So it makes good sense to carefully evaluate your home’s cooling options to select the right system to meet your needs.

Keeping comfortable and cost-friendly

No matter what unit or system you choose, how you adjust your thermostat determines your ultimate savings on your electric bill. Start by setting the temperature as high as is still comfortable, keeping the difference between indoor and outdoor temperatures as small as possible.

Take advantage of the “energy saver” mode on window units, and use programmable thermostats for multiroom or whole-house systems so your machines don’t do extra work to cool the place when nobody is home.

When you’re ready to cool down, don’t drop immediately to an extremely cold temperature — starting that low won’t speed up the cooling process, but it will make your machine work harder and expend more energy.

If you want to offer your machine — and your energy bills — a little relief, proper ventilation in your home can certainly aid your cool-down efforts. Ventilation improves indoor air quality, removes moisture and odors, and allows fresh, cool outside breezes to be exchanged for stuffy indoor air.

Start boosting your home’s natural ventilation simply by opening doors and windows, especially in the evenings. Encourage airflow by installing ceiling fans, window fans, and attic exhaust fans to push hot air outside and draw cooler air into your home.

In the summer months, ceiling fans should be set to run in a counterclockwise direction, drawing cooler air up from the floor. A whole-house attic exhaust fan will pull hot air into the attic, where attic vents can dissipate the heat. Even positioning a few portable fans near windows or a basement door at night can draw the cooler air from these areas into the home.

Regular maintenance for maximum cool down

With a variety of cooling practices in place, you’ll want to maximize the efficiency of your efforts by performing proper maintenance.

  • Seal the deal. Make sure you have adequate insulation in the walls and ceilings to keep hot air out and cool air in. Caulk leaking windows and doors, and use draft “snakes” to cover the gaps at the bottom of these entry points. Adding aluminum blinds, insulated curtains, or window tint film can block even more sunlight from entering your home and heating up the place during the day.
  • Change your filter. This quick and easy chore reduces the burden on your air conditioner, improves indoor air quality, and helps you — and your air conditioner — breathe easier. Check the filter once a month and clean out any dust particles that might clog the system, forcing it to work harder and waste energy.
  • Clean the coils. An air conditioner’s coils and fins on the outside of the unit should be kept unobstructed and cleaned regularly. Use a soft-bristle nylon brush to gently remove any debris, and hose off any leaves or caked-on dirt. Clean the inside coils using the soft brush attachment on your vacuum cleaner, or wipe down with a soft, damp cloth.
  • Call in a pro. Even though much of keeping your home cool can be considered do-it-yourself work, it is still important to call in a reputable HVAC contractor regularly. An annual system tune-up can help ensure that your air conditioning system is working efficiently and will go a long way toward prolonging the useful life of the components.
