Can Bad Ductwork Reduce the Efficiency of Your HVAC System?

When it comes to HVAC systems, most homeowners don’t put much thought into their ductwork. It’s not surprising—although it’s responsible for moving air throughout your home and keeping you comfortable, the ducts are hidden away in the walls, ceilings, floors, and crawlspaces. 

However, if you want your HVAC system to work as efficiently as possible, it’s important to put some attention on the “V”—for ventilation—in HVAC!

Damaged Ductwork

If your ventilation system is old or it wasn’t installed properly, it may be damaged. Vibrations or improperly installed connections can cause your ductwork to become loose or even collapse, inhibiting the airflow. If the lining begins to pull away, this can create a more significant blockage and cause your HVAC system to work overtime. 

Over time, normal wear and tear can lead to cracks, leaks, and corrosion; damage can also be caused by renovations or pests. If left for too long, the damage will worsen and may eventually cause leaks and blockages. Defects in the ductwork, like sharp bends or dents in the material, can also cause airflow problems that reduce the overall efficiency of your system. 

The bottom line is that the harder your system has to work to compensate for blockages or air leaks, the less efficient it will be. It’s also likely using more energy to heat or cool the air—which also leads to higher energy bills. If your ductwork is over 10 years old, we recommend scheduling an inspection. 

Improperly Sized Ductwork

If your system has always been noisy or became noisy soon after installation, the ducts are likely improperly sized. When the ducts are too large, it causes low airflow. You may find that the temperatures throughout your house are uneven. Ducts that are too small will cause noise from restricted airflow. 

It’s common for ducts to make some noise as your system moves air through them and the temperatures fluctuate, but it shouldn’t be very noticeable. Like damaged ducts, improper ductwork size or installation can put a dent in your efficiency—and your wallet. Your HVAC system will struggle to keep your home comfortable and, as a result, add more wear and tear to the motors, and compressors. This can lead to a more frequent repair cycle or the need for a premature replacement. 

Dirty Ductwork 

Dirty, dusty, or moldy ductwork can cause the air filters to clog up more quickly, increasing airflow resistance and making the system work harder. It can also compromise some of the system’s internal components, resulting in breakdowns and repairs. Keeping the ducts clean will improve performance, efficiency, and longevity while also improving your indoor air quality. 

Is it Time to Schedule Service for Your Ductwork?

Can Your Heating and Cooling Ductwork Go Bad Over Time?

Every time South Carolina goes through a cold snap, you probably wonder what the heating bill will look like. You may worry about the bill going up and try to retain as much heat as possible in the house by sealing up drafty windows and doors and using rugs on hardwood floors. Sometimes, even with your best efforts, the bill still seems high. What can you do?

If your heating bill is high, one of the first places to look is your HVAC system. The easiest step is to check the filter. PECO recommends changing your filter every thirty days. If your filter is clogged with dust and debris, your system will be working hard to push air through it – and be pushing that dirt right back into your home!

Another factor to consider is your ductwork. Deteriorated ductwork can actually be leaking warm air, costing money and forcing your HVAC system to work harder than necessary, which can decrease the life of your system.

The Age of Your Ductwork

Old Ductwork

Do you know how old your ductwork is? Ductwork can start to deteriorate in as little as ten years if the original job wasn’t done correctly; the seams and seals can start to break down, letting air seep out. You may be able to see exposed duct work in the house and see signs of aging. Are the ducts cracking, sagging, or coming apart at the seams? Do you see any streaks of dust near seams?

Feel the airflow in different rooms of your house. When you turn on the air, can you feel it easily flowing through the vents in the living room, but feel just a trickle of air in the bedroom? Is there a distinct temperature difference between rooms? These could be signs that your ducts have deteriorated or there are heavy air leaks.

Duct systems today have an R8 insulation value and require all seams to be sealed with specialized tapes and adhesives. Our PECO team tapes, bands, and screws all the duct components together. This keeps seams sealed, as overtime, the tape can loosen as adhesives age.

Detriments of an Old System

Older duct systems had to meet lower energy standards than today’s duct systems. Some homes will have a grey plastic/fiberglass covering but are not sealed at the insulation seams. A few very old homes with original duct systems will not have any insulation at all!

If you have concerns about your ducts, the best thing to do is contact your local HVAC contractor. Existing duct systems where the insulation has come unwrapped in a few places can be repaired, however, if the entire system has become unwrapped it is best to replace everything.  Tapes don’t stick to old, dusty insulation and seal properly. PECO can fix or replace old ducts, which can have a big impact on your comfort level in your home by allowing air to freely flow and can help decrease the bill! Contact PECO today to make an appointment to inspect your ductwork.

Beat Allergy Season with Clean Air

Do you find yourself sneezing, coughing, or wheezing during certain times of the year? If so, you could be one of more than 50 million Americans who suffer from seasonal allergies. Seasonal allergies can range in symptom severity. Mild symptoms may be a general annoyance, while more severe cases can make you wonder whether you have allergies or an illness.

What Causes Seasonal Allergies?

Seasonal allergies can be triggered by many environmental factors. While seasonal allergies can strike throughout the year, they often affect most people as the weather turns from cool to warm, when plants and trees begin to bloom. During the warmer seasons, different plant species release airborne pollen, which causes an immune response in people with allergies. Histamines and other chemicals get released into the bloodstream, which causes an allergic reaction.

Seasonal Allergy Symptoms

Many pollens can trigger seasonal allergies, but the most common ones include:

Beat Allergy Season With Clean Air
  • Grasses, like Timothy or ryegrass
  • Ragweed
  • Birch
  • Cedar
  • Alder
  • Horse chestnut
  • Willow
  • Poplar
  • Sagebrush
  • Tumbleweed
  • Thistles

Seasonal allergies are commonly traced back to these trees and plants because their pollens are particularly irritating. Warm, windy weather is generally the worst for seasonal allergies because pollen counts rise in warm temperatures, and the wind spreads it far and wide. Common symptoms of seasonal allergies include:

  • Allergic rhinitis: a stuffy or runny nose, nasal irritation
  • Sneezing
  • Watery, itchy eyes
  • Itchy throat
  • Congestion in the ears, throat, and nose
  • Postnasal drip
  • Coughing
  • Headaches

Some types of seasonal allergies can also cause a secondary illness, like:

  • Contact dermatitis
  • Hives
  • Asthma or mild breathing problems
  • Itchy skin, nose, and throat
  • Conjunctivitis

Seasonal allergies can affect people of every age, but they’re especially important to treat in children because they can cause re-occurring earaches and other infections.

What to do for Seasonal Allergies

Thankfully, there are many things you can do to get some relief from seasonal allergies, including:

  • Reducing pollen exposure by staying indoors
  • Avoiding yard work or gardening
  • Washing your hands and showering after you’ve been outdoors
  • Using a pollen mask outside
  • Allergy shots or immunotherapy
  • Oral antihistamines
  • Decongestants
  • Nasal sprays and sinus rinses
  • Plant supplements, like butterbur and spirulina
  • Acupuncture

HEPA Air Filters and UV Lighting

In addition to these methods, keeping the air in your home clean is one of the best and most essential ways to prevent the symptoms of seasonal allergies. The Mayo Clinic recommends always using your air conditioning and high-efficiency particulate air (HEPA) filters in your home. HEPA filters are a type of mechanical air filter that works by forcing air through a fine mesh. This traps small particles that can cause allergies and asthma, like pollen, pet dander, dust mites, and tobacco smoke.  For those with severe allergies, it may also be worthwhile to invest in a whole-house central air purifier.

Installing UV lights throughout the home can also help with seasonal allergies. UV lights eliminate contaminants that can lead to poor air quality, including mold, mildew, fungi, airborne viruses, bacteria, and spores. While UV light doesn’t filter the air, its been shown to play a huge role in secondary allergy prevention, especially when used in combination with HEPA filters.

The best way to prevent seasonal allergy symptoms and stay comfortable year-round is to take a multi-pronged approach. Reducing your exposure outdoors while keeping the air inside your home clean and free of contaminants can greatly reduce your exposure to allergy-causing contaminants. At PECO, we offer several types of HEPA filters, as well as UV lights. Some of our filter options include Lennox 5” HEPA filter, PureAir HEPA filters, and MERV 11, 13, and 16 HEPA filters. Experts are predicting 2020 will be a bad year for allergy sufferers, especially here in the eastern United States. Above-normal rainfall and near-average temperatures are expected to contribute to above-average pollen levels. If you suffer from seasonal allergies, now is the best time to get your home prepared!

Duct Diseases You Can Cure

There are a pretty large number of issues that HVAC technicians constantly battle, but one of the most common are the afflictions that your duct systems face. If you have noticed a lackluster performance from your ventilation system – don’t panic, because the team of professionals at PECO Heating & Cooling are here to help.

The first step to fixing something is to determine the problem, and a faulty duct system could have several. A common one is poor duct static pressure. If you weren’t aware (which many aren’t), static pressure in a duct refers to the resistance of airflow in your system. You need to make sure that the push of the air is greater than the actual resistance to the flow, otherwise the flow could be too low or even non-existent. Think of it like your body’s blood pressure, if the amount is too high or low, then that is an indication of poor health/performance.


Excessive noise, improper airflow, equipment degradation, and total system failure could all be results of improper static pressure. Our team can identify these problems by performing an airflow or static pressure check. An airflow check is the process of checking the amount of airflow that your fan is producing and how much of that airflow is delivered to each register or grill. After taking these measurements, we will compare the results to standard pressure and airflow rates. If the measurement does not meet the expected standards, then you have a problem. Here are a few common causes and how they can be identified:

– Undersized Air Ducts
One potential cause for this could be undersized air ducts, the common solution for which is to perform a complete renovation of your duct system. Our technicians will identify which ducts need work by performing an airflow test, and then will replace them with ducts that are the appropriate size. Sometimes replacements are not always necessary though, and the solution could be something as simple as opening a closed balance dampener.

– Blocked Ducts
Another issue that can be identified by measuring and comparing airflow to the necessary standards, although you may be able to check just looking to see if the grill is squished to the point that nothing could pass through or is blocked by debris. Sometimes blockage can also be caused by a dead animal that managed to make its way in there, though this probably isn’t the case (you would definitely smell it). The solution for a blocked duct may be as simple a quick cleaning, but it could also require more extensive repairs or an outright replacement.

– Duct Leakage
Duct leakage is an issue that will affect virtually every duct system at some point. Leakage can be identified by improper air flow (starting to see a pattern?) or by checking a duct’s tightness level. A common cause is a lack of sealant or proper duct sealing material. Acceptable sealants vary by state, so be sure to leave it up to the professionals to provide you with the right materials.

These are just a few of the potential problems and causes of a faulty duct system, there are many more. Thankfully, the team here at PECO Heating & Cooling can easily identify and fix whatever problem is causing your duct system to perform poorly.
