How Does Your Attic’s Ventilation Affect Your Energy Bill?

Attic ventilation plays an important role in maintaining a comfortable environment in the home. In fact, problems like mold and mildew and hot attic temperatures in summer can all be offset by adequate attic ventilation.

In winter, for instance, attic vents help to remove moisture from the home. This ensures problems like mold and mildew are avoided.

Yet, in summer, the attic ventilation helps to keep attic temperatures down. And that can result in real energy cost savings.

Here’s why: The summer sun beats down on the roof of your home, pushing attic temperatures over 120 degrees. This super-hot air eventually radiates into the living space, resulting in warmer interior temperatures. Ultimately, you’ll have to run your air conditioning unit longer to offset this unwanted heat gain.

How Does Attic Ventilation Work?

If you’ve ever had to retrieve something from the attic in August, you know it gets hot up there – very hot. Fortunately, your home’s insulation prevents a lot of this heat from seeping into the home. Yet, on the hottest days of the year, insulation alone isn’t enough.

Proper ventilation helps to offset the stress that’s put on the insulation.  Basically, attic ventilation systems facilitate air circulation in the attic. Air intake and exhaust vents generate a natural flow of air – cooler air in via the intakes, warm air out via the exhaust vents – that helps to push the super-heated air up and out of the attic.

What Types of Attic Vents Are Available?

Attic vents are necessary for creating a circulation flow of air within the attic. In terms of exhaust, there is a range of options available; the most common include:

  • Power Vents: Power vents, sometimes called PAVs, resemble box vents, but they have an electric or solar-powered fan within that help to draw moisture and hot air out of the attic. The most advanced PAVs have thermostats and humidity detectors that trigger them on.
  • Ridge Vents: Ridge vents sit along the length of the roof’s horizontal ridges. An advantage: Ridge vents help to prevent hot and cool spots in the attic; creating a more even cooling effect.

What Role Do Attic Fans Play in Ventilation?

In addition to vents, your attic’s ventilation system can also benefit from fans. Yet, there are a few different types, each offer different benefits. If you want to install an attic fan, the two most common types are:

  • Whole Home Fans: A whole house fan can greatly reduce your cooling costs. Essentially, this type of fan is fitted in the attic, and they’re meant to be operated at night when temperatures have cooled. Most whole home fans are floor-mounted over a central hallway within the home. They require windows on the lower floors to be opened. When turned on, the fan draws cool air through the windows, up and into the attic, helping to push warm air out of the attic. Whole house fans energy requirements are just 10-15 percent of what you could expect from the A/C unit.
  • Attic Ventilation Fans: Attic ventilation fans are typically mounted to an exterior wall in the attic. This type of system blows hot air out of the attic, but it can have a negative effect. If the home is not properly insulated, a ventilator fan can actually draw cool air out of the home, resulting in an increased cooling load.

Improving Attic Ventilation for Cost Savings

Ultimately, improving your attic’s ventilation can have a net positive effect on your cooling bill. But attic ventilation requires a balance. Too many attic vents can cause temperature fluctuations in cold weather months, and too little venting will not do enough to dissipate heat in the summer.

The best advice: Consult with an HVAC specialist. A specialist will help you choose the right type of attic venting system for your roof, they can help you maximize your energy savings, and will ensure that the venting systems are properly placed and installed.

3 Ways to Make Sure Pests Don’t Enter Through Your HVAC

Pests enter your home through numerous pathways. Some are obvious like leaky windows or doors. Yet, one that’s often overlooked is your home’s HVAC system. Gaps and holes in your HVAC system offer convenient access for pests like stink bugs, silverfish, and rodents. But what can you do to ensure your HVAC is protected?

Fortunately, pest-proofing your HVAC system doesn’t require costly investments. A few minor maintenance tasks, regular inspections, cleaning and occasional pest prevention will help you avoid a full-blown infestation.

HVAC Pests: Why Prevention Is Best

From foul odors to costly damage, rodents, insects, and small animals can do a lot of damage to your home in a small amount of time. By taking regular abatement measures, you can prevent damage from occurring. What types of problems do they cause? Here are a few of the most common:

  • Home and equipment damage: Pests can cause significant damage to your home. Termites, for example, can destroy wood structures, leading to thousands of dollars in repairs. When it comes to your HVAC, damage occurs in a few ways. For one, pests love to move into your outdoor air conditioning unit. An A/C infestation can cause performance issues and even failure. Inside, pests can damage or eat through ductwork and seals.
  • Air quality issues: An infestation can affect your health by diminishing interior air quality. Odors, pesticides, allergens and pest debris can all infect your home’s air quality.

HVAC Pest Prevention Measures

A few specific pest abatement measures can help protect your HVAC system long-term. In particular, keep a close eye on areas where pests can enter your HVAC system: Exterior vents and flues, outside equipment, and your home’s ductwork. Steps you can take to protect them include:

  1.     Seal Ducts, Vents and Flues

Exterior vents like an attic vent, soffit or dryer vent all pose potential pathways for pests. Similarly, you want to ensure that the ductwork is properly sealed. Not only will this help prevent pests infestations, it can also help you save on heating and cooling. Small gaps and cracks within the ductwork can turn into pest highways, which is particularly problematic because odors, debris and allergens carried by the pests into the ductwork will be distributed around the home.

  1.     Regular Duct Cleaning, HVAC Maintenance

Even with the best seals, pests will find ways to enter the home. One strategy to prevent larger issues is proper duct cleaning. By cleaning your ducts, you’ll remove any debris and allergens that have collected, and the HVAC cleaning professional can help you identify potential problem areas. Also, pay particular interest to the dryer vent. Dryer vent inspection or cleaning should be conducted several times per year to prevent lint build-up, which can attract rodents and insects.

Another strategy: HVAC maintenance. A seasonal tune-up for your A/C or heating equipment will ensure that pests like stink bugs haven’t infested the equipment. Bi-yearly cleanings, inspections and maintenance checks are recommended.

  1.     Clear Outdoor Units

Your air conditioning unit is exposed to the elements, and without proper protection, it can become a magnet for pests. One strategy: Ensure that the unit has been properly mounted on a raised slab and that grass and weeds are regularly cut back away from the unit.

Alternatively, you can set traps for pests local to your region. For example, in some areas, stink bugs can infest HVAC units. Setting stink bug traps around your HVAC unit can help to solve the problem. Additionally, setting stink bug traps near vents will help to limit the pest’s ability to enter the home.

 

An HVAC system that’s not properly maintained can attract problem pests. Prevent damage to your home and health by ensuring your system is properly protected. Regular duct cleaning and maintenance help to clear issues and identify problem areas. Contact us for more information today.
