Winter Ventilation Options for Your Home

Winter Ventilation Options for Your Home

We’re lucky to experience relatively mild winters on average in Peachtree City. Every now and then, we even get to turn off the heating and open a window or two when the weather is mild. But during cold spells, the air in our homes can get mighty stuffy, as we keep the heating on and the windows closed. There are ways to freshen your home’s air in the winter, however, with the following ventilation options.

Fresh Air From a Window

If you have an older home, you may have cracks and crevices that allow a bit of fresh air to move inside. Although this isn’t an efficient way to ventilate, at least your indoor air quality is probably better than that in an airtight home. You can open windows a bit during the winter, just long enough to let stale air out, and let fresh air in.

Exhausting Stale Air

Bathroom and kitchen exhaust ventilation systems are often recommended to get rid of damp air in areas where moisture is likely to build up, causing mold and other problems. The air in these areas is also often stale, retaining cooking and bathroom odors. Exhaust ventilation should be ducted to the …

When to Consider a Heat Recovery Ventilator

When to Consider a Heat Recovery Ventilator

A heat recovery ventilator (HRV) represents a new solution to household ventilation issues. With today’s tightly-sealed energy efficient homes, it’s more critical than ever to get fresh air into the house. In the enclosed environment, indoor air quality suffers as pollutants, water vapor and airborne particulates accumulate.

Exhaust Fans Aren’t Enough

Simply exhausting indoor air with one-way exhaust fans isn’t an optimum solution. Because stagnant air removed from the house isn’t replaced by equal amounts of fresh air, the home becomes depressurized. This makes temperature control more difficult, causes the HVAC system to run longer and compromises indoor air quality due to infiltration of unfiltered air.

A Balanced Approach

A heat recovery ventilator consists of a central controller that incorporates separate intake and exhaust fans. The intake system draws fresh air through a filter and distributes it throughout the house through dedicated, small-diameter ductwork. Meanwhile, the exhaust system draws stale air out of the house through separate ducts and exhausts it outdoors. The controller ensures that the volume of air drawn into the house by the intake fan equals the air volume removed by the exhaust fan, thus maintaining balanced indoor air pressure.

Considering Improving Your Home’s IAQ by Using UV Lights? Here’s What You Need to Know

Considering Improving Your Home

Although they require professional installation and incur maintenance costs over time, UV lights could be the most effective and convenient way to improve your indoor air quality (IAQ). These lights are silent, have no moving parts and create no odors.

What They Do

Selecting a UV lighting system for air purification and better IAQ reduces the number of harmful viruses, bacteria, mold spores, allergens and volatile organic compounds (VOCs) in the air. They work by altering the DNA of organic compounds that prevents them from reproducing. They’re one of the few ways of reducing harmful VOCs in the air. VOCs are especially stubborn and can cause serious health problems.

Installation and Operational Issues Their placement. The safest and most effective placement for these lights is inside the HVAC system, where they will treat all the air blowing through it. The lights need to be hidden from view, since the spectrum they emit will harm eyesight, even with a short exposure.

In this humid climate, the lights can sit inside the air handler to shine on the evaporator coil to prevent mold and biofilm growths during the cooling season. They can also be installed inside the ductwork in a position where …

Whole-Home Dehumidifiers: Better IAQ and Comfort

Whole-Home Dehumidifiers: Better IAQ and Comfort | Powers

Georgia summers can mean oppressive humidity that makes warm days feel even hotter. Inside the home, you will feel cooler with the A/C running, but the HVAC system alone isn’t usually enough to combat all of the moisture in the air. A whole-home dehumidifier can help, and here’s how.

Experience Better Indoor Air Quality

High humidity provides a welcoming breeding ground for bacteria, mold, mildew and even dust mites. As mold spores, dust mite waste and other allergens build up in your home’s air, you and family members can experience typical allergic responses, such as irritated respiratory passages, sneezing and coughing, sinus infections or even asthma attacks.

A whole-home humidifier decreases some summer misery by making your home a less hospitable environment for mold, dust mites and bacteria. It allows you to keep indoor humidity below 50 percent, which improves air quality. Your household will breathe better and feel better.

Enjoy Improved Comfort

A muggy afternoon feels hotter than a dry afternoon even when the thermometer indicates the temperature is the same. This is because on a dry day, your perspiration evaporates quickly and you experience the cooling effect of that. On muggy days, the air is already full of …

Improve IAQ With the Help of Houseplants

Improve IAQ With the Help of Houseplants | Powers

Indoor air quality is a consistent issue in both business and residential settings. Fumes, odors, and gases, many of them potentially harmful, can be produced by common indoor sources. While mechanical air filters and purifiers work well at keeping indoor air quality high, you can also turn to a decorative and natural method for removing indoor pollutants: houseplants.

Houseplants produce oxygen and consume carbon dioxide as part of their lifecycle. A good selection of indoor plants can give your home or office air a boost by introducing more oxygen and removing more carbon dioxide. However, houseplants can do much more to make your indoor air fresher and cleaner.

Indoor environments often contain substantial amounts of pollutants. Construction materials, such as carpets, lumber, or manufactured building materials, can give off fumes and gases such as formaldehyde. Appliances, heating systems, and other fuel-burning devices can produce carbon monoxide, an extremely harmful gas. Cleaners, paints, varnishes, solvents, pesticides, and other household chemicals can release strong, often unpleasant odors. Houseplants can help remove these fumes, dangerous gases, and other chemical substances from your indoor air.

Some of the more common houseplants that provide air filtration and pollutant removal are:

Aloe (aloe vera) — This …
