Indoor air quality is a major concern. Minnesota winters are cold. This means that windows are closed for months on end, limiting airflow. This limited flow of air from the outside means everyone is breathing the same air. Eventually, that air becomes stale air, which is how head colds and respiratory issues can come about. Fortunately, it is possible to improve the air quality through the HVAC system. When considering all of the contaminants that can be in the air, the ability to clean the air becomes even more important.
Some of those contaminants can include:
- Carbon monoxide
- Household products
- Tobacco smoke
- Mold or mildew
- Nitrogen dioxide
- Lead particles
- Asbestos in older structures
Improving Indoor Air Quality
If you think the above pollutants look frightening, it’s because they are. When it comes to your HVAC system, you may be thinking, “but I have a furnace filter on my furnace.” That’s great if you have a good filter. However, these filters are designed to trap larger particles, such as dust bunnies and hair. This means that more comprehensive measures need to be taken to improve the quality of indoor air during the winter.
On your own, you can opt for different types of filters, such as electrostatic filters. These filters require monthly cleaning with pressurized water and can be difficult to clean thoroughly. If not maintained properly, the filters can clog, which can make the blower motor work harder.
If you opt for a portable air cleaner, you are only able to clean a specific zone. These systems also have a tendency to create ozone. Even in small quantities, ozone can hurt lung tissue.
The last option is the professionally installed filtration system. At Metro Heating & Cooling, we are able to provide you with whole-home filtration, which means the air quality is improved throughout the entire house rather than a single room or zone.
Today’s air quality systems are very efficient in the removal of particles as small as 5 microns in diameter (a strand of hair is 100 microns). You can receive great particulate efficiency and even address VOCs and other indoor gasses that may be present in the air.
Thorough Duct Cleaning
Duct cleaning is another way to improve air quality. By taking the dust out of the ductwork through professional cleaning by your St. Paul HVAC company, a major difference can be made in air quality as it pertains to dust allergies. Consider that the average home has five times more dust than an area outside of the same square footage. This creates a great environment for bacteria and dust mites.
If you notice any of the following, it may be time to have your ducts cleaned:
- You are having respiratory problems
- Asthma is acting up more than usual
- Allergies are in hyperdrive
- Dust is on your furniture
- A musty smell or stale odor develops when the furnace runs
- You have headaches, itchy eyes, or nasal congestion
If you have a smoker in the house, pets, or your furnace uses standard filters, duct cleaning can be a valuable tool for making the air healthier and much more pleasant during the winter.
It’s also important to remember that central AC units can also trap dust, so duct cleaning can even have its benefits during the summer. One main difference between the summer and winter is that you can open windows for good air exchange. However, opening windows can also let in outside dust.
