The Surprising Link Between Heating Systems and Breathing Issues
As temperatures drop and heating systems turn on, interior settings alter in ways that may influence respiratory health. From dry air to circulating allergens, a home’s heating system directly impacts air quality. Many homeowners may be unaware that something as basic as a neglected furnace filter or unregulated ductwork may cause respiratory difficulties, especially for individuals with asthma or allergies.
Alps Heating & Air Conditioning, Inc. in Orange County, CA helps homeowners install heating systems that won’t pollute the air and lower indoor air quality. Read on to learn how heating systems influence indoor air quality (IAQ) and how to protect your respiratory health all winter.
How Heating Systems Affect IAQ
Although necessary for comfort, heating systems may circulate dust, pet dander, pollen, and other allergens throughout the house. Forced-air heating systems are particularly susceptible to transporting these particles via the ducts and vents if they aren’t properly maintained, bringing allergies into residential areas. Over time, these toxins may pile up, affecting air quality and respiratory health.
Poor air quality may cause coughing, sneezing, shortness of breath, and even persistent respiratory problems in people with asthma, allergies, or sensitive respiratory systems. Even those who have no prior respiratory issues may feel symptoms when exposed to allergens and irritants in the air, particularly if their heating system amplifies these levels.
Common Heating Issues That Create Respiratory Problems
More humidity control is often needed for heating systems. Unfortunately, when the air is too dry, it can hurt the nose and throat. In the winter, when heating systems move air around the house, this dryness often gets worse, causing sore lips, dry skin, and even nosebleeds.
In addition to dry air, older or unmaintained systems often contain dust and other contaminants in the ducts. If left unaddressed, these particles can continually be pushed into the home’s air, contributing to poor indoor air quality. If heating units don’t have enough air flow or have certain types of old screens, they may also release dangerous gases like carbon monoxide.
HVAC Technician Solutions
One way to improve indoor air quality is to upgrade to a high-efficiency air filter. Regular air filters only trap larger particles, while high-efficiency particulate air (HEPA) filters can capture smaller particles, including allergens, dust, and other contaminants. HVAC technicians can recommend and install a suitable filter that meets the household’s needs. Changing filters regularly, typically every one to three months, is important to maintain your air quality.
To counteract the dryness caused by heating systems, HVAC technicians can install a whole-home humidifier that regulates indoor humidity levels. Proper humidity can prevent the air from drying out, keeping nasal passages and respiratory tracts hydrated, which is particularly helpful for asthma and allergy sufferers. These humidifiers are installed directly into the HVAC system, automatically adjusting humidity levels throughout the home, providing a balanced environment supporting respiratory health.
Over time, ducts accumulate dust, debris, and even mold if there is excess moisture in some regions of the home. Dirty ducts can lead to poor air quality, allowing contaminants to circulate whenever the heating system is on. HVAC professionals can perform duct cleaning, which involves removing accumulated dust and debris, thus reducing the potential for allergen spread. In cases where leaks are present, technicians can also seal ducts to prevent contaminants from entering through cracks, ensuring cleaner, more efficient airflow.
Heating systems that use propane or natural gas are more likely to give off carbon monoxide, which is dangerous at high amounts. Being exposed to carbon monoxide can cause serious health problems, such as damage to the lungs and, in the worst cases, death. An HVAC technician can help inspect the heating system for proper ventilation and ensure carbon monoxide detectors are correctly placed and functional.
Air Purifier and Ventilation
Adding an air purifier can further enhance indoor air quality for homes with high levels of outdoor pollutants or for those with family members who are highly sensitive to allergens. Standalone air purifiers can capture airborne particles and provide cleaner air in specific rooms. At the same time, whole-home systems can integrate directly with the HVAC system to purify air throughout the house. HVAC technicians can assist homeowners in selecting a system that best suits their needs, considering the home’s layout, existing HVAC setup, and budget.
Proper ventilation is also necessary for IAQ. Without adequate airflow, allergens and contaminants can build up, creating a stale indoor environment. HVAC technicians can assess a home’s ventilation system and suggest ways to improve airflow, such as adding exhaust fans, upgrading ductwork, or adjusting air intakes. Improved ventilation helps dilute indoor pollutants, allowing for cleaner, fresher air.
In some cases, technicians might recommend a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) for homes that experience issues with airflow. These devices help exchange stale indoor air with fresh outdoor air while preserving the temperature balance, making them an effective solution for homes with limited ventilation options.
