The Heat Lurking in Your Attic: It'll Sneak Downstairs if You Let ItNo matter the season, keeping your home comfortable should be high on your priority list. But staying cool in the summer can be expensive and challenging – for reasons you may not be aware of. For one thing, heat in the attic may be battling your air conditioner to control the temperature throughout your home. A properly insulated and ventilated attic will prevent excessive heat from penetrating your home, reduce wear on your air conditioner, and lower your energy bills.During the Phoenix area’s long cooling season, the sun beats down on your roof and heats the air in your attic. The heat – easily reaching temperature in excess of 150 – can radiate down through the ceiling and into the rooms of your home, without proper insulation and ventilation. This makes your air conditioner have to work harder to keep your house cool. It can be even worse in homes where the air conditioning ducts run through the attic, where the heat dilutes cooled air as it’s pumped through. There are several ways to reduce the heat that enters your home, with attic insulation being an important one.

When it comes to insulation, you want to make sure it does the job it’s meant to do. For example, cellulose insulation can be blown into the attic to slow down heat transfer through your home’s ceiling. Unfortunately, its effectiveness can be diminished by other factors, such as the installation of plumbing, wiring, HVAC systems, etc. For example, pipes running through your attic may have gaps around them that allow air to pass through, undermining the protection provided by insulation. Any holes or gaps should be sealed before putting in your insulation.

In addition to reducing heat transfer through the floor of your attic, it’s equally important that the attic has proper ventilation. Heat that builds up from the summer sun needs somewhere to go. Allowing the heat to escape lessens the possibility of it seeping into your living area. Proper venting, with the addition of an attic fan, is essential to control that heat in the attic.
