If you’re prone to allergies, you might have mixed reactions about the coming of spring. The warm weather and pretty flowers are nice, but if you’re sneezing and coughing and not feeling well because of your allergies, they can be tough to enjoy. Going inside your home should be an escape from outside air contaminants, providing relief, right?
A properly working HVAC system can help to rid the indoor air of the contaminants, providing that escape allergy-sufferers seek. By filtering and circulating the air, HVAC system rids dust from the home by catching it and keeps it from piling up by moving the air around. So, as long as the HVAC is properly working, you can rule out your HVAC system as the cause of your allergies. On the other hand, if you feel like you’re sneezing every time the air turns on, you may want to consider that your HVAC system isn’t working properly.
If your allergies are worse when you’re inside than when you’re outside during the spring (or anytime, for that matter), then consider what kind of indoor air pollutants are gathering in your house and how you can help your HVAC system do its job.
Types of indoor air contaminants
The most common types of indoor contaminants are dust mites, pet dander, combustion from cooking, and mold. Dust mites are distant relatives of ticks and spiders– tiny bugs whose waste and carcasses are found pretty much in every American home. That’s right– they don’t bite and generally leave us alone, but for the unlucky few affected by dust, it’s usually dead dust mites and their waste that are affecting those who are allergic .
Pet dander is another allergen that is pretty disgusting to think about. Those who are bothered by allergies including pet dander are not typically allergic to their actual pet, but rather dried saliva, urine, and skin flakes that their pets spread about the house with scratching and shaking.
Combustion of any kind of material leads to emissions into the air. This includes smoking cigarettes and wood-burning fireplaces, but most commonly comes from cooking with oil or using gas stoves.
Another common allergen or pollutant in the house is mold, which grows in humid or damp areas or where water collects. Mold releases spores into the air which in turn grows more mold, causing allergy symptoms when these spores settle into dust piles.
Pollen can also find its way indoors and collect in dust piles and circulating in the indoor air. Without a quality HVAC system or one that filters the air, the typical symptoms from pollen-induced allergies can result.
Less common household air pollutants
Although less common, carbon monoxide, radon, disease-carrying animals and their waste, and bacterial infections and viruses can result in airborne contaminants with serious side effects. Normally you would determine the presence of one of these pollutants quite quickly, but it is possible for low levels of contaminants like these to contribute to allergy-like symptoms and other more serious symptoms.
Sick or allergies?
It can be difficult to tell what’s going on when you have allergy symptoms, because of the multiple symptoms you may experience. If you’re really experiencing an allergic reaction to allergens in the air inside your home, you’ll typically have cold symptoms like a runny nose, sneezing, coughing, itchy or watery eyes, or an itchy throat. But it’s also possible to have headaches, a low-grade fever, or skin reactions like eczema.
While you shouldn’t take our word for it— we’re HVAC doctors, not people doctors— it’s definitely worth following up if you have any of these persisting symptoms. If it is a reaction to some type of indoor air contaminant, your symptoms could worsen to the point of having trouble breathing or developing into something more serious than allergies.
How to combat indoor air contamination
- Cleaning your HVAC system
Inspecting and cleaning your HVAC system is a good first step to make sure it’s not part of the problem.
Cleaning or replacing your air filters and cleaning the vents are the primary steps to making sure your HVAC system can do its job. Clogged air filters will strain the overall system. Dust in and around the vents only creates more clogging and blows around dusty air.
You also might consider having your HVAC system professionally cleaned or at the very least inspected during a tune up. During a springtime tune up, an HVAC professional can check the parts you might not be able to access, cleaning inside the unit itself or the ductwork.
- Cleaning carpets and other fabrics
Vacuuming carpets and even couches and mattresses, washing any washable fabrics like stuffed animals and blankets, and keeping the home as dust-free as possible are the best ways to help your HVAC system to do its job.
- Ventilation & air purifiers
The EPA recommends regular “natural ventilation” through open doors and windows. While you might think that keeping the pollen and other outdoor air pollutants out is the best option, fresh air is helpful for flushing out any pollutants that might have gathered indoors.
Another great option for especially sensitive or allergy-prone people is an air purifier with a good filter. Air purifiers help HVAC systems do their job by removing allergens. The air circulated by the system is then more likely to be free of allergy-causing contaminants.
Replacing your HVAC system
If your HVAC system is old and not effectively circulating or filtering the air in your home, if the ductwork is leaky or poorly constructed, or if an old thermostat is hindering your HVAC’s performance, it may be time to consider repairing or replacing your HVAC or affected units. Without good humidity control and air flow, allergens listed in this article can collect and air quality can suffer.
Having a quality HVAC system that is working at peak capacity is one of the best ways to improve indoor air quality.
