Benefits of Getting a Duct Cleaning After Summer

Benefits of Getting a Duct Cleaning After SummerA lot can happen inside the ductwork of an HVAC system during an average summer. If your HVAC ducts haven’t been used as part of your indoor cooling system, they might be dirtier than you expect, and contaminated with material that could reduce your indoor air quality or even make you and your family ill. Take the following factors into consideration when deciding whether to have a duct cleaning performed after summer.

What Can Happen to Ducts?

If your HVAC system ductwork isn’t used for several months, you could see effects such as:

  • Accumulations of dust, dirt, fibers, hair, and other household-related particulates.
  • Accumulations of dead insects or insect parts, animal fur, or feces.
  • Infestations of insects, rodents, or other vermin.
  • Breaking or loosening of seals at duct connections.

Is Duct Cleaning Necessary?

Some authoritative sources, such as the U.S. Environmental Protection Agency (EPA) say that duct cleaning should be limited to three very specific circumstances:

  1. Mold can be seen inside the ducts or on HVAC equipment.
  2. Ducts are completely or partially blocked.
  3. Ducts are infested with insects, mice, or other vermin.

However, remember that if there are any types of particulates or other contaminants inside your ductwork, a professional cleaning can remove them. During a cleaning, the ducts can also be inspected for condition, quality of connections between segments, and quality of seals at connections.

The Benefits of Duct Cleaning

  • Indoor air quality is improved since there are fewer contaminants being moved through the ducts and into your home.
  • Material that could cause asthma attacks, allergy attacks, or illness has been removed.
  • Air moves more freely down the length of the ducts, improving HVAC system performance and efficiency.
  • Ductwork damage, loose segments, or broken seals can be found and repaired, decreasing wasted energy and money from air leaks.

How These HVAC Components Work Together in Your Home

How These HVAC Components Work Together in Your HomeIf you’re like most homeowners, you think of your air conditioner and furnace as independent pieces of equipment. The truth is that these main HVAC components and many others are all part of one integrated comfort system that’s in place to regulate temperature, humidity and air quality in your home. Here are some of the key system components and how they work together:

Thermostat

Your thermostat is control-central for all the heating and cooling functions of the HVAC system. Using built-in sensors, the thermostat monitors the indoor temperature and sends a signal for your A/C, heat pump or furnace to cycle on and off based on your selected temperature settings.

Duct System

If you have a forced-air system, it relies on a hidden network of ducts to circulate air throughout your home. Supply ducts deliver conditioned air, while return ducts transport stale air back to the HVAC equipment for reconditioning. Problems with the ductwork like leaks, disconnections or improper sealing and insulating can negatively impact your comfort and the HVAC system’s energy efficiency.

Air Handler

The HVAC system’s air handler unit contains some key components including the evaporator coil that pulls out heat and humidity and cools the air, the heat exchanger and fuel burner for the furnace, the blower fan that pushes air through the system, as well as the air filter that captures debris particles. Problems within the air handler unit can adversely affect the entire HVAC system. A dirt buildup on the filter or evaporator coil can lead to airflow restrictions, poor temperature and humidity control, a decline in efficiency and reliability. Corrosion or cracks in the heat exchanger can let fumes containing deadly carbon monoxide into your home’s air supply.

Outdoor Unit

The outdoor unit contains two vital cooling system components; the compressor that pumps refrigerant and the condenser coil that releases the heat captured indoors. If problems arise with either of these components, the system’s cooling efficiency declines, as does your comfort.

Tips for Detecting Air Leaks in Your House

Tips for Detecting Air Leaks in Your HouseIn a perfect world, we’d all schedule professional energy audits regularly in our homes to find energy leaks. In the real world, however, a professional energy audit isn’t always within our budgets. So, we’re faced with the do-it-yourself route when it comes to correcting air leaks.

Why Locate Leaks?

The Department of Energy cites air leaks as the major source of energy losses in homes. Conditioned air escapes through air leaks, while unconditioned air finds its way inside, undermining our cooling and heating efforts. Some of the major sites for leaking air:

  • Under doors
  • Around door and window frames
  • Through hung windows
  • Around baseboards
  • Through attic hatch doors and around frames
  • Through any holes to the outside, such as those for pipes, wires and cables
  • Switch plates and plugs
  • Recessed lighting
  • Fireplace dampers
  • Vents and flues
  • Dryer vents
  • Mail slots

Outdoors, the major leak sites are faucets, exterior corners and where the foundation and siding/brick meet.

 

You can find places where air is leaking by visual inspection, checking for gaps or holes, or by lighting an incense stick and waving it in front of suspected leak sites. If the smoke wavers, air is leaking.

Fixing Leaks

Apply the following fixes to leaks:

  • Weatherstripping around attic hatches and on doors
  • Weatherstripping between hung windows
  • Caulk or weatherstripping around baseboards
  • Caulk around door and window frames
  • Door sweep under doors
  • Insulation and weatherstripping around pipes, wires and cables entering from the outdoors
  • Foam gaskets behind switchplates and electric plugs
  • Specially made heat-resistant insulation boxes around recessed lighting in the attic
  • Metal collar around flues in the attic, plus heat-resistant caulk
  • Weatherstripping or caulk around dryer vents and mail slots

In addition, insulate all exterior faucets. Apply caulking and weatherstripping around mail slots and foundation seals. Make sure caulking around exterior door frames is in good shape.

Unsealed Ducts = Wasted Energy and Money

Unsealed Ducts = Wasted Energy and MoneyFew home improvement projects offer as many benefits as duct sealing does. Leaking ducts cause high energy bills, poor indoor air quality (IAQ) and may even pose health risks. The U.S. Department of Energy reports that the typical home may lose from 20 to 30 percent of its conditioned air due to ductwork problems, chief among which is leakage.

Cuts Energy Costs

When ducts run through unconditioned spaces and they leak, that air you’ve paid to condition enters the attic, crawl space, or basement, where it’s wasted. It will cost more to heat and cool your home depending on the size and extent of the leakage. A sudden increase in heating costs can indicate a ductwork problem, and costs will remain high until the duct is sealed.

 

If the leak is in the return ductwork, problems with your HVAC system could develop, since it relies on a specific amount of air flowing into it for the best energy efficiency. Low airflow in a gas furnace can even trigger a safety switch that turns the system off until it cools down.

Improves Air Quality

If someone in your home suffers from allergies or asthma, consider duct sealing to alleviate their symptoms. A leak can pull particulates into the air from the areas through which it runs that might include dust, insulation particles, or mold.

Health Considerations

If you use any vented gas appliances, leaking ductwork can pull carbon monoxide (CO) into your home’s air by backdrafting the gas into the ducts. Although CO is lethal for all everyone, CO is especially damaging at lower levels for infants, pregnant women, and people with heart or respiratory problems.

Comfort Factors

Sealing the ductwork solves problems associated with uncomfortable rooms that don’t receive their full allotment of conditioned air because of leakage. A room whose air seems stale or stuffy might have a leak in the duct supplying the conditioned air.

 

Duct sealing cuts energy costs and improves the health and comfort of your home. To learn if your ductwork needs attention, contact Powers Heating & Air, providing trusted HVAC services for Peachtree City homeowners.

Signs of Ductwork That is Aging

Signs of Ductwork That is AgingOne of the household systems that many of us tend to take for granted is ductwork — the network of large, usually square pipes that distributes conditioned air throughout the house, and then returns it to HVAC equipment to be reheated or cooled. At some point in the life of your home, you’ll have to address old ductwork that’s no longer doing its job. If you know some of the signals of aging ductwork, you can repair or replace it before it starts wasting energy and eroding home comfort.

What Happens When Aging Ductwork Fails?

Ductwork that’s been in a home for 15-20 years or longer is prone to gradual failure, with leaks developing between connections and in other places. Ducts leaking heated or cooled air into unconditioned spaces such as crawl spaces, wall cavities and the basement forces the HVAC system to work harder to make up for the lost air. It wastes energy, erodes comfort and stresses equipment.

Leaky ductwork also can be prone to backdrafting, a phenomenon where dirty or contaminated air (or even carbon monoxide) gets sucked into holes in the ducts, then is circulated into household air.

How Can You Tell You Have Old Ductwork?

  • It might be as simple as checking the age of your house if it still has the original ducts. If the house and its ductwork are older than 15 years or so, you should hire a trusted professional to inspect the ducts, employing special high-tech equipment. They’ll recommend a course of action, including possible repair or replacement.
  • Inspect visible, accessible ductwork. If you can see that it’s loose or notice rust or corrosion, this is another sign that it’s old and needs attention.
  • If airflow in your home seems inconsistent from room to room, it could signal some duct runs are leaking or even disconnected.
  • Are your heating and cooling bills higher than in the past with no obvious explanation? Old ductwork could be the culprit.
