Attic Ventilation Don t Let Poor Ventilation Make Your AC Work Harder this Summer

What purpose does attic ventilation serve? On the surface, this seems like a simple question, but there's a lot more to attic ventilation than meets the eye. One of the obvious functions of attic ventilation is keep the hot summer heat from entering your house. That's because during warmer months, attic ventilation help keeps your attic and the rest of your home cool. During colder months, attic ventilation reduces moisture to help keep your attic dry and prevent ice dams. With a more in-depth understanding of the general purpose of attic ventilation, it's time to discuss the specifics. The exact purposes of an attic ventilation system are to provide added comfort to your attic and the rest of your home, to help protect your home from possible damage, and to help reduce your home's energy consumption year round.

What happens to a home on a typical summer day, and how can attic ventilation help?

Radiant heat from the sun hits your home's roof.The roof temperature typically increases when this happens, and heat travels into the attic. As heat builds up in the attic, it radiates to the attic 'oor, and then into nearby living areas, raising temperatures there. So, in a home without attic ventilation, or without proper ventilation, you can imagine how much temperatures would rise in the home as heat builds up over the course of the day. But, in a home with proper attic ventilation, heat build-up in the home is less of an issue, and often not an issue at all.

Eventually, if attic ventilation and insulation isn't properly done, the accumulation of heat begins to have more expensive consequences for your home than just electricity consumption. Some of these consequences are caused due to the actions taken by homeowners to cool themselves.Think about it - to reduce the effect of the heat, we usually change the thermostat to a lower temperature. We may also turn on additional fans and window air conditioners. As the hot weather continues to build, these appliances run longer and work harder - a fact well documented by utility companies. Homeowners pay for all this added energy consumption in higher utility bills, but the continuous use of the HVAC systems in your home is also taking a toll. The HVAC systems in your home are working in overdrive to combat the rising temperature caused by inadequate attic ventilation, which could mean additional costs in repairs and maintenance of the entire HVAC system, and perhaps even an earlier replacement of the HVAC system. Don't let poor attic ventilation make your air conditioning system work harder this summer - contact a professional now to make sure that your home has proper attic ventilation and insulation

.A less obvious but equally costly consequence of improper attic ventilation can be found on the roof of your home. Homeowners can't see it as it happens, but the effects are obvious over time. When an attic ventilation system isn't properly installed, excess attic heat can cause some roof shingles to distort and deteriorate. The result is premature failure of roong materials, which means that the roof may begin to leak. Also, animals such as birds and rodents may more easily find their way into your attic if your roof is deteriorating, and the costs add up fast - from additional repairs to pest removal and structural repairs. Sometimes, homeowners may need to buy a new roof earlier than expected because of an inadequate attic ventilation system.

So, what is the link between attic insulation and attic ventilation? Efcient attic insulation actually increases the need for effective attic ventilation. This is because heavier insulation absorbs more heat, so additional heat gain may occur. That also means it's less likely that overnight cooling alone can remove the heat that builds up in an attic during a prolonged period of hot, sunny weather. The solution to this problem isn't to reduce the insulation in the attic, as some homeowners may believe. That would only create problems at other times of the year, especially the colder winter months. Instead, the goal is to design an attic ventilation system that is energy efficient, and effectively compensates for the additional heat gain produced by the high levels of insulation in the summertime. To summarize, effective attic ventilation also helps cool attic insulation if the heat from the sun causes additional heat gain.

Attic ventilation can't minimize the transfer of heat from the roof to the attic, but it can minimize its effect. To do so, an efficiently designed system must provide a consistent flow of cool air along the underside of the roof sheathing. It's crucial for the air flow to be uniform - meaning that the intake and exhaust vents must be balanced. Otherwise, "hot spots" can form in the attic, which can have negative effects on the efficiency of the system. The steady, cool, and constant air flow will carry heat out of the attic, before it can transfer to the attic floor and infiltrate the rest of the home. That means that your attic and the rest of your home will remain comfortable all summer long. Additionally, your home's air conditioning system will be able to do less work while still keeping your home cool and comfortable.

There are many types of attic ventilation systems that can work for your home. It all depends on your home's size, age, geographic location, and the type of weather that your home typically experiences. The type of attic ventilation you choose is also affected by how well-insulated your attic is. It's best if instead of guessing about all of these issues, you should consult with a licensed and insured contractor who is an attic ventilation professional. Although the problems of attic heat and moisture have different causes, one solution that can help with both situations is effective attic ventilation. A high efficiency attic ventilation system allows for a consistent flow of air to keep the roof sheathing cool in the summer months, and free of ice buildup in the winter months. In both cases, this means less damage to your home, and a more comfortable home for your family as well. Additionally, proper attic ventilation means that your HVAC system will not have to work as hard to keep your home cool in those hot summer months.
