Why Replacing Insulation is Important

replacing insulationInsulation is an essential but often overlooked component of your heating and cooling system. While many homeowners know that it helps keep warm air out of their homes in the summer and retain indoor heat during the colder months, they have no idea that a time comes when it’s crucial to start replacing insulation.

The Need to Replace Insulation

Several factors make it necessary for you to replace your home insulation:

  • Loss of effectiveness — Insulation deteriorates over time. Consequently, it could allow heat gain in the summer and heat loss in the winter.
  • Maintain structural integrity — Your attic insulation can damage your home’s structure. If you ignore it for long, old insulation can facilitate mold and rotting of beams.
  • Health — Rodents can make old or damaged insulation their home and leave behind harmful contaminants. These contaminants can spread to other areas of your home and put your health at risk.

When to Replace Insulation

So how do you know it’s time to replace insulation? The tips below will help:

  • When replacing your roof — You should replace your attic insulation together with your roof.
  • Your home is too warm or too cold — If your house gets too hot very quickly during the summer months or too cold in the winter, chances are your insulation requires replacement.
  • Odor coming from the attic — Does your attic have an odor? That’s a good sign that your insulation has been a victim of pest infestation. You should have it removed quickly.
  • Don’t know how old your insulation is — If you can’t remember the last time your home was insulated by a professional, the existing insulation is probably too old. Consider replacing it.

Replacing insulation is a critical part of keeping your home healthy, comfortable, and energy efficient. If you need help finding out if your insulation is up-to-date or needs urgent replacement, make sure you only work with a reputable professional.

Summer Insulation Best Practices

Summer Insulation Best PracticesWe all know insulation is important in the winter It keeps warm air from rising into the attic, allowing it to stay in your home longer, keep your house more comfortable, and save you energy. But did you know that insulation is just is important in the summer?

Here’s how insulation can help you in warmer weather, as well as a few tips on making sure your home is properly insulated.

Summer Insulation Benefits

Insulation does two things in warm weather. First, it keeps warm air in the attic. As you cool your home, a lot of that cold air flows outside, only to be replaced by hot air from your attic, flowing in. Attic insulation helps keep that hot air out, allowing your home to stay cool longer. Wall insulation can help too, keeping the warm, humid, outdoor air from getting in, so your A/C can work more efficiently.

The other thing insulation does is protect your roof. The top of your roof is hot in the summer, as the sun beats down on it. When cold air leaks into the attic from your home, it makes the underside of the roof cooler. That temperature disparity can damage your roof, causing leaks, as well as leading to mold and mildew. Insulation keeps the heat in your attic, so your roof temperature remains even.

Summer Insulation Tips

The most important place to insulate is your attic. Before you do, though, be sure to find and seal any air leaks that would allow hot air to flow into your home. Loose-fill is inexpensive, effective, and provides good coverage, making it an ideal choice. Make sure there’s between 10 and 14 inches of insulation in the room, and seal and insulate the attic door as well.

You might also consider insulating your ducts. This helps keep cold air cooler as it flows through them, allowing it to cool your home more efficiently. Talk to your HVAC contractor about how to insulate ductwork.

Helpful Tips for Checking Insulation Levels in Your Home

Helpful Tips for Checking Insulation Levels in Your HomeAs the summer heat leaves your attic, it’s a good time to check its insulation level. Nothing affects the cost of maintaining your comfort year-round as much your attic. Improving the level is one of the most cost-effective and durable ways to enhance the energy efficiency of your home, and fall and winter are the ideal times to do it.

Inspecting the Attic

Dress appropriately for the visit to the attic. Wear a washable long-sleeved shirt and pants, and don a dust mask. The existing insulation in the attic and the dust that settle up there are respiratory irritants. If your home is older, check it for vermiculite insulation that may contain asbestos. You may need to have a contractor test it first for safety because asbestos is a known carcinogen.

Use a ruler or rigid tape measure to measure the levels. If you can see the tops of the joists at first glance, you need more. The U.S. Department of Energy recommends that homes in this climate have an insulation level of at least 10 inches of loose or batt insulation in the attic, and up to 20 inches.

If your attic doesn’t have a sturdy floor, lay planks or a sheet of plywood across the joists to walk through it. Look over the condition of the insulation throughout the entire attic to make sure it’s distributed evenly, not compressed, and no mold is present.

Looking for Leaks

As you explore the attic, you may see cracks and gaps around the vents, pipes, flues, wires, or recessed lighting fixtures that exit into the attic. Your HVAC system’s ductwork may also run through this area, and excessively dusty deposits near any part of it could signal ductwork leakage. Cracks and ductwork leaks drive up energy bills and should be sealed by an HVAC contractor.

After checking the insulation level, you’ll know whether it needs improvement. The next step is to contact Powers Heating & Air, serving Peachtree City homeowners, to learn more about increasing it and sealing the air leaks for greater home energy efficiency.

A Guide To Insulating Your Crawl Space

insulating your crawl space peachtree georgiaInsulating your crawl space is an important part of a whole-home approach to energy savings. Whether you are trying to keep heat and humidity out during the summer or keep warm air in during the winter, you need to make sure you have the right insulation for the job.

Follow this guide for insulating your crawl space, and you will save all year long:

  • Moisture barriers – Since there is no sunlight and airflow is inconsistent through the crawl space, moisture accumulates there and can cause big problems like rotting wood, insect infestation and mold growth. You can solve this issue with vapor barriers or encapsulation systems. Vapor barriers alone don’t remove moisture but they stop it from reaching the wood and flooring of your home. Encapsulation systems, on the other hand, line the outside of the crawl space and the ground to form a finished space where moisture can be easily controlled. Both solutions should also be complimented with a drainage and ventilation system to remove moisture from the area entirely.
  • Insulation levelsInsulation is rated by its R-value, which is its thermal resistance. Georgia homes need insulation of at least R-19 for the floor and crawl space. The insulation should cover the entire floor and must be protected from the moisture below by one of the vapor barriers mentioned above.
  • Outside air – You want to control the amount of air and humidity that enters the space. Typically, this is done with concrete blocks with vents or registers that can be opened or closed, depending on the season. The registers allow you to pipe in air from your home and keep the crawl space roughly the same temperature so humidity remains balanced. The vents control the supply of outside air so you can bring in fresh air when needed. The exterior of the space needs to be sealed in all places other than the vents and registers.

Before insulating your crawl space, contact Powers Heating & Air. We help homeowners in Peachtree City and the surrounding areas find the right products, install them correctly and maintain them for long-term savings and comfort.
