Older air conditioning systems may do much more than struggle to keep your home cool. Many people do not realize that outdated or neglected systems can also lower indoor air quality. Air conditioners work by circulating air throughout your home. If this circulated air picks up dust, mold, or allergens along the way, it can spread pollutants around the house. Understanding how your A/C system may affect the air quality of your home typically helps you make the best health decisions for you and your family alike.
Your Air Conditioner and Air Quality – What’s the Connection?
Air conditioning systems are designed to help with cooling, as well as some basic air filtering. However, not all systems are designed to accomplish the same tasks when it comes to improving or keeping indoor air quality at an optimum level. Newer A/C units typically come equipped with better technology to filter out pollutants, allergens, and dust. These new systems are also commonly better at circulating clean air throughout your home.
On the other hand, older air conditioners often cannot keep up with the demand that is placed on them. If the A/C system is several years old or has not had regular maintenance, it may collect dirt and dust over time. This buildup can impact air quality, especially if ducts and filters haven’t been regularly cleaned. It’s always a good idea to schedule routine air duct cleaning and air conditioner filter replacement for better air quality and a more efficient cooling system.
Ways Your AC System Can Impact Air Quality
Keeping indoor air quality at a high level commonly depends on your air conditioning system’s condition. A newer AC system can make keeping your home’s air quality good. However, an old A/C system will often struggle to do the same. Dirty A/C ducts, damaged ductwork, and an old A/C unit air filter are just a few aspects that can easily cause a negative impact on the quality of your indoor air. These issues can also become worse over time if left unattended.
Here are some of the ways an outdated or neglected system can make a difference in your home’s air quality:
Dirty/Damaged Ductwork
Damaged or dirty ducts can trap dust, mold, and bacteria. Air passes through these ducts and can spread contaminants throughout your home as your air conditioner runs. Dirty A/C ducts are a common problem, especially in older homes where ductwork may have developed leaks or damage over time. These leaks usually allow pollutants to enter, impacting indoor air quality. Scheduling air duct cleaning may help remove built-up debris from the ducts.
Air Filter Needs Replaced
The A/C air filter is a critical part of your cooling system’s ability to clean indoor air. Over time, air filters collect dust, pet dander, and other small particles. A clogged or old A/C system filter can reduce airflow and cause poor air circulation in your home. Once the filter is full, particles can easily make their way back into your indoor air, which reduces the air quality that you want in your home. An air conditioner filter replacement should happen regularly, based on the manufacturer’s recommendations.
Old AC System
Older A/C systems lack the advanced filtration and airflow control that newer models provide. Older systems do not commonly perform well when it comes to filtering out pollutants, which are contaminants such as dust and mold spores, which may be circulated around your home. Over time, this often causes indoor air quality to become worse. Older systems also tend to work less efficiently than newer ones. Sometimes, even upgrading to a newer model with improved filtration is the best way to resolve this issue.
Closing Thoughts on How to Improve Indoor Air Quality
Indoor air quality is something that every homeowner should not overlook. An outdated A/C system, dirty ducts, and clogged filters all contribute to a cooling system that causes poor air quality. Scheduling regular A/C maintenance, air duct cleaning, indoor air quality testing, regular air conditioner filter replacement or system replacement can typically help keep pollutants out of your home and provide you with better indoor air quality.
