6 Warning Signs Your Air Ducts Need Cleaning Or Replacement

Most people give little thought to their HVAC system’s ductwork until something has gone horribly (and expensively) wrong with it. This is a huge mistake as a little preventative air duct maintenance can go a long way toward keeping your system running efficiently and preserving the indoor air quality of your home or business.

Clearly here in Jacksonville, Florida, air conditioning is something you do not want to live without. With average highs in the low-to-mid 90s in the summer and an average daily humidity of around 74 percent (or 90+ percent during the rainy season or if you live close to the water), life in Jacksonville becomes quickly unbearable without a properly functioning air conditioning unit.

Your air ducts are important infrastructure for your HVAC system. Your ducts provide a conduit for the cool or heated air produced by your HVAC system to flow into the various rooms of your home to achieve your desired temperature. When ducts are obstructed or have leaks, it can cause your system to lose efficiency, running up your energy bill and increasing wear and tear on your HVAC unit.

Air conditioning repair experts recommend duct cleaning approx. every five years to dislodge dirt and other debris in the ducts. If your ducts haven’t been cleaned in a while, here are a few signs that cleaning is needed immediately.

Visible Signs Your Ducts Need Cleaning

  • Unexplained spikes in your energy bills -–- If your bills are climbing and there’s no good explanation for the hike, such as increased usage or mechanical problems with your unit, you may have clogs or leaks in your ducts that are reducing the system’s efficiency. Air conditioning repair services can inspect your ducts to see if this is the problem and take steps to clean and seal your ducts as needed.
  • Signs of rodent or insect infestation -–- If you see or smell evidence that rodents or insects may be living in your ducts, it’s time to have your ducts cleaned if they are all metal or replaced if non-metal like flex ducts or duct board. A rodent infestation will saturate urine, feces and other unhealthy contaminants permanently into the fibrous duct. If you see one place of damage on a flex duct system, then the entire interior of the air distribution system probably has damage that a repair cannot address since rodents will damage the plastic inner duct lining throughout the interior of all the flex ducts (which is the types of ducts used mostly here in Jacksonville, FL). Debris from these infestations can cause damage to your HVAC system too, reducing its efficiency. Over time, the smell from droppings and other debris can also become highly unpleasant and unhealthy. Contaminants from rodent or insect droppings and shells and husks from insects circulating through the air that you and your guests breathe can cause sickness. A rodent or insect infestation in your ducts represents a big health threat, and one you should deal with immediately.
  • Dirt and debris around your vents -–- If you’re noticing dirt and debris around your vents, there’s a very good chance that your ducts have developed blockages or have a high number of contaminants circulating through the system. High levels of dirt and debris circulating through your system can exacerbate allergies and other respiratory problems. Although having your ducts cleaned will not eliminate dust in your home, it’s well worth your while to have your ducts cleaned to remove the dust build up.
  • Unexplained respiratory problems -–- If you or members of your family are having unexplained allergy, sinus, asthma, or other respiratory problems, excessive dirt, and debris circulating through your ducts may be the problem. Air cycles through your home about seven times a day, and if your ducts have high levels of dirt and debris, it can have a big impact on indoor air quality. If sneezing and wheezing have become a problem in your home, and if it’s been years since your last duct cleaning, you may want to call an air conditioning maintenance company out to inspect your ducts and clean them. You may also want to consider more indoor environment control to combat against the dust sources as it develops inside of the home by adding indoor air cleaners, air sanitization systems, fresh air systems, dehumidification systems, a better AC filtration system and possibly sealing the homes building envelope from cracks that compromise the interior environment.
  • Dusty air filters or air return grilles -–- If your recently installed air filter is covered in dust, chances are that your ducts are clogged and need cleaning. Return air grilles with thick, fuzzy coatings of dust are also indicators of higher than normal dust particulates within the indoor living environment. There can be many sources to high amounts of dust. Many times, it is the people and creatures living in the house that are the dust source. Vacuuming carpets can drastically reduce dust levels in your home. And so can sealing the air boots (located behind air vents) having cracks that can vortex dust, heat and humidity from the attic or crawl space as air is pulled or distributed into the home.
  • Visible mold growth -–- Because of Jacksonville’s humid climate, mold growth is a huge problem. Mold exposure in homes has been linked to many health issues, some of them very serious. Mold can often cause respiratory issues, eye irritation, throat irritation, and even skin irritation. People with compromised immune systems or chronic lung illnesses may develop serious infections if exposed to mold. Even if mold is found in your AC system, many times it is not the source. Since the AC System circulates all the air inside of your home it will pull in spores that are coming from almost anywhere from inside of the home, into and through the indoor cooling or heating unit and then grow on the wet and dark indoor AC evaporator coil acting like a Petri dish. We can clean it off but if the source is not found and eliminated then it will most likely return.

If you see mold growing around your vents or inside your ducts, do not hesitate to call an air conditioning repair company to perform an inspection and cleaning of your ducts. Mold is more prevalent in Florida than most parts of the country, so homeowners must be constantly vigilant against this serious health threat. Catching mold infestations early before they can spread throughout the home and become difficult to eradicate. A system and duct cleaning can help reduce the cost of remedying this problem. Although many microorganisms (or mold) are harmful there are many that are very common and not so harmful to homeowners. Sometimes it depends on the individual who can have a negative reaction to something that seems to not bother others? Be sure to consider that AC Contractors Air McCall and its agents are not mold experts. If you suspect any health issues due to dust or sources of mold in your home, we always recommend that you contact a good home hygienist like Mitch Kramer at Martin Enviro if you want testing to find out if you should be concerned or not and seek a professional medical diagnosis if you have symptoms that you suspect are related to your indoor environment.

How Ducts Are Cleaned

Professional duct cleaning services can provide a thorough cleaning far beyond what the average homeowner can do on his or her own. Air conditioner maintenance service technicians have specialized tools and training that allow them to remove nearly all dust and contaminants from duct work, even in the most hard-to-reach places.

Technicians will use specialized air HIGH pressure hoses and other tools to loosen debris within your ducts. (Brushes can cause air leaks by damaging the interior of flex duct and fibrous duct board which is mostly what is used here in Jacksonville Florida.)

Next, they will use a vacuum to remove dirt and debris from the ducts. They will also likely clean the cooling coils and the blower unit. Your technician may also decontaminate your ducts with germ and odor-killing compounds. In addition to cleaning the ducts and other parts of your unit, your technician will also clean grilles and vents. We use Abatement Technologies for the duct cleaning process.

Taking care of your ducts can reduce your power bills and increase the longevity of your HVAC system by reducing its workload. As new HVAC systems can cost thousands of dollars to install, keeping your system running efficiently for as long as possible can save you lots of money. Regular cleaning of your HVAC ducts can also greatly benefit the indoor air quality in your home or place of business.

Poor indoor air quality is being increasingly linked to a variety of illnesses, and modern home design has made maintaining good indoor air quality difficult because new homes are so tightly sealed for energy efficiency purposes. Cleaning your ducts can help keep mold and contaminants from constantly recirculating through your home and giving rise to respiratory and other illnesses.

When hiring a company to perform air duct cleaning services, make sure you hire a professional company with the tools, training, and experience to do the job correctly. Check online reviews and ask your friends and neighbors who they use for air conditioner service. Talk to prospective service providers about their professional credentials and experience. Also, don’t be afraid to ask prospective providers for references.
