Red Flag Warning Signs That Your Air Ducts Collected Too Much Dust This Winter!
As winter quickly fades and spring cleaning begins all across the country, countless homeowners are now focusing on things like their windows, closets, and a thorough cleaning of their living spaces.
However, one essential aspect of seasonal upkeep that tends to get overlooked this time of year is a home’s air duct system. During the cold winter months, heaters run frequently, windows stay closed up, and pet hair, dust and debris all build up within ductwork. This means that by the time spring actually arrives, a home’s air ducts could potentially be circulating all sorts of harmful particles—and not just cool air…
This is why we recently interviewed Salt Lake City, Utah’s top-rated duct cleaning technicians at Apex Clean Air to help our readers better recognize some of the red flag warning signs oriented around air ducts collecting far too much dust during the winter, so check out the below sections to see if it’s time for your property to invest in a professional cleaning appointment this spring!
Abnormal Amounts Of Dust Around Your Home
By far one of the most noticeable red flags that homeowners can recognize this time of year is dust circulating throughout their properties.
If you’re wiping down surfaces far more than usual and noticing how dust settles on those same surfaces shortly after cleaning them, it’s a clear warning sign that something is wrong with your property’s air ducts.
It’s normal for dust particles to accumulate inside ductwork systems over the winter as your heating system runs every day, and when your HVAC system switches into spring cooling mode, these particles can end up circulating throughout your rooms and landing on floors, furniture and shelves.
Your Air Vents Are Blowing Out Dust
Another eyebrow-raising indicator that your air ducts need professional cleaning is when you can visibly see dust coming from your vents or settling around them.
It’s also very troubling when you notice small puffs of debris or dust near your vent openings exactly when you turn your HVAC system on, and these symptoms are often accompanied by vent covers appearing discolored or dirty.
The unfortunate truth is that this high level of dust buildup is common during the winter months when we keep your homes fully sealed from the harsh weather elements, because without fresh air circulating in our homes, dust becomes more likely to collect and turn into a serious issue!
Worsening Indoor Allergy Symptoms
Springtime naturally brings all sorts of seasonal allergies, but no one wants their allergy symptoms to get worse when they go inside their homes!
Indoor allergy symptoms can often get worse this time of year when dirty air ducts are contributing to the problem. This is partially because pollen and dust will enter into your ducts, only to be combined with other airborne particles that are already lingering deep within your system.
These particles then get spread throughout your property when you run your HVAC system. So, if you notice that you or any of your family members are coughing, sneezing or experiencing more irritation while spending time indoors, it could be a good idea to investigate the overall cleanliness of your ductwork.
Musty Smells & Uneven Airflow
It’s possible for air duct systems that collect a lot of wintertime debris to also have a direct impact on a home’s airflow. This could mean that certain rooms will feel abnormally stuffy, whereas others will receive too much airflow.
Dust buildup can also often lead to musty or stale odors when you start up an HVAC system during the spring months.
And although there are many causes of musty smells, dirt ductwork just so happens to be one of the top culprits this time of year—which is exactly why it should be a part of your spring maintenance routine!
Your HVAC System Went Through Constant Winter Usage
Even if you’re not actually noticing any glaring signs of dust accumulation in your home, it’s important to understand that your heating system likely went through heavy usage this past winter—which naturally leads to ductwork debris accumulation.
This issue particularly impacts homes in cold climates that rely on heating systems for 5-6 months per year, because this level of heating necessity subsequently means that your home’s indoor air is constantly being recycled through your ducts.
And the more frequently your HVAC system runs during the winter, the more accumulation opportunities there are for pet dander, dust, and all sorts of other harmful particles that are known to gather in air ducts.
You Haven’t Had Professional Air Duct Cleaning In Several Years
Another huge factor for homeowners to keep in mind this spring is the general timing of their professional air duct cleaning appointments.
It’s never a good sign when you can’t remember the last cleaning appointment you had, and if it’s been several years, the odds are that this spring is the right time to reach out to your local technicians and thoroughly evaluate your ductwork system’s cleanliness and attention needs.
Routine inspections and cleanings always go a long way to ensure high indoor air quality (IAQ) and proper airflow in homes as temperatures start to get warmer in April and AC systems start running again!
Air Duct Cleaning Needs To Be A Part Of Your Spring Maintenance Routine This Year
Spring is often the perfect time of year to double-check all sorts of home systems, and while not every home will need air duct cleaning this season, it’s still important to pay close attention to some of the common red flag warning signs that could occur at your property over the next couple of months.
If you’re noticing issues like poor airflow, excessive dust accumulation or indoor allergy symptoms, it could be a good idea to reach out to your area’s duct cleaning experts for a system inspection.
When you combine duct cleaning with other types of seasonal maintenance like cleaning vents and replacing HVAC filters, you’ll be doing your part toward ultimately addressing buildup and prepping your property for the ensuing summer months ahead.
And by including your air ducts as just another part of your spring maintenance routine, you’ll reap the benefits of a more comfortable and cleaner indoor environment as the seasons begin to change!
