Most homes in the Peachtree City area rely on central, forced-air HVAC that uses a duct system for air distribution. In a home’s finished living space, the ducts are placed behind the ceilings, walls or under the floor, and the only portions visible are the HVAC vents covering individual duct openings. Here’s a helpful primer on the types of HVAC vents you’ll find in your home, and what they do:
Understanding Supply and Return HVAC Vents
If your HVAC has a duct system that’s properly designed for balanced airflow, it has a specific number of supply ducts to deliver conditioned air, and return ducts that draw stale air back to the equipment for reheating/cooling. It’s easy to tell the difference between these two kinds of ducts based on appearance of their vent covers:
Most rooms in your home will have one or two louvered HVAC vent covers known as registers. These vents usually have a integrated damper with either a lever or rolling control that you can open and close to adjust the amount of airflow. Even though your register covers are adjustable, it’s vital to always keep the louvers fully open, because closing some can upset air balance …
A kitchen remodel is a perfect opportunity to install or upgrade kitchen ventilation. Why do you need kitchen ventilation? So many reasons — from preventing mold and mildew, to lowering your home’s overall humidity so you don’t feel so warm and have to crank down the air conditioner. Also, a kitchen vent system helps remove odors and smoke from cooking so you have better indoor air quality.
Installing kitchen ventilation is a plus, not only for your comfort, but adds to the resale value of your home.
So here’s what’s involved:
Has Your Home Had Kitchen Ventilation in the Past?
If you have an older home, it may have had ventilation in the kitchen in the past. Perhaps the ductwork is in place and is vented to the outdoors, but it’s not attached to your range hood. Or, you may have a ventilation system that just recirculates the stale air, pulling it up into the system, and sending it back into your home’s interior. Another scenario might involve a ventilation system that is ducted into spaces between joists in the ceiling, or into the attic.
Any of these situations should be corrected during your upgrade.
You probably use your kitchen and bathroom ventilation fans regularly to help remove cooking smoke, lingering odors and steam. These are obvious and immediate indoor air quality issues. Other indoor air quality issues, such as allergens, germs and VOCs, aren’t as obvious day to day, and may be trapped and proliferating in the rooms you spend the most time. Keep reading to learn about ventilating options to make your home more healthful and comfortable.
Bedrooms and Living Rooms
The most important areas in your home to ventilate are the rooms you spend the most time. These are typically your bedrooms and living rooms. Bedrooms which you frequently keep doors closed are especially important to ventilate to alleviate stuffiness. Further, you’ll rest better.
Every time you open an entry door or a window, there is air exchange. Air exchange also occurs through air leaks. Though, if your home is tightly sealed for better efficiency, it’s also sealing in pollutants. The problem with ventilating your home via windows, doors and air leakage is that you have very little control and weather often doesn’t permit.
In Peachtree City’s humid climate, good indoor ventilation is essential for your comfort and health. Bathroom ventilation is especially important due to the extra humidity in this room.
How Good Ventilation Helps
Taking showers, flushing the toilet, and washing your hands all add moisture to the air in your bathroom. Ventilation removes the trapped moisture, which provides a number of benefits.
Stay more comfortable — High humidity can make you feel chillier in low temperatures and hotter in high temperatures. With better humidity control you’ll feel more comfortable after showers and as you prepare for your day. Minimize bacteria growth — Potentially harmful bacteria such as staphylococcus (staph infection) and streptococcus (strep throat) are less prolific in conditions with lower humidity. Prevent mold and mildew — Mold is less likely to develop in conditions with humidity levels below 50 percent. You’ll have less mildew on your grout, walls and ceilings, and fewer mold spores to threaten your respiratory health. Reduced condensation — With less excess moisture in the air, you’ll see less condensation on your windows, mirrors, and shower walls.
Planning Your Bathroom Ventilation
It’s completely normal for your central air system to make noise. The outdoor unit is going to hum and whir from the powerful fan and compressor. You may even hear swooshing sounds from refrigerant circulating through the indoor air handler. Though, if noisy air vents have reached levels that disturb your normal activities, use these tips to get to the root of the problem.
Noisy Supply Air Vents
Whooshing — Airflow exiting the supply vents can make quite loud whooshing noises if the supply air ducts are too narrow, the ducts are caked with debris and/or one or more vents are closed. Make sure all air vents are open. Use a flashlight to look inside the vents to check for excessive dirt. If the noise persists, contact your HVAC provider for a duct inspection. Flapping — If duct joints separate or loosen, the adjoined metal duct sections will rattle, flap and clamor. Wrap loose or disjointed duct sections with metal tape. Popping — If your ducts are installed outside your home’s insulation barrier, the ducts are susceptible to extreme differences in temperature inside and out. This causes duct metal walls to expand and contract, which causes loud popping sounds. Installing …
