When homeowners think about HVAC systems, comfort is usually top of mind. But did you know your heating and cooling equipment plays a major role in your home’s indoor air quality (IAQ)? In fact, poor HVAC maintenance is one of the most common causes of unhealthy air indoors.
At Tarrant Mechanical, we help families across the DFW area improve indoor comfort and wellness by optimizing their HVAC systems. Let’s explore how your HVAC affects indoor air quality—and what you can do to ensure the air you breathe is clean and safe.
The Environmental Protection Agency (EPA) reports that indoor air can be 2 to 5 times more polluted than outdoor air. Poor IAQ can lead to:
Since most people spend over 90% of their time indoors, especially at home, improving indoor air quality should be a top priority.
Your HVAC’s air filter is the first line of defense against dust, pet dander, pollen, and other pollutants. If it’s dirty or too basic (low MERV rating), it won’t effectively capture harmful particles.
Tip: Upgrade to a high-efficiency filter (MERV 11–13) and change it every 1–3 months.
Leaky or dirty ducts distribute dust, mold spores, and allergens throughout your home. Poorly sealed ducts can also pull in contaminants from attics or crawlspaces.
Solution: Tarrant Mechanical offers duct cleaning and sealing services to improve airflow and keep pollutants out.
High humidity levels (over 60%) can promote mold and dust mites, while low humidity causes dryness. An unbalanced HVAC system or lack of a humidifier/dehumidifier contributes to poor air regulation.
Fix: We can add whole-home humidifiers or dehumidifiers to maintain optimal indoor humidity between 30–50%.
Neglected HVAC systems accumulate moisture and dirt—ideal conditions for mold and bacterial growth. This can lead to musty smells and airborne irritants.
What we do: During routine HVAC maintenance, our techs clean coils, check for moisture buildup, and disinfect components when necessary.
Modern homes are sealed tight for energy efficiency, but this limits fresh air exchange. Your HVAC’s ventilation system is essential for removing stale indoor air and bringing in clean outdoor air.
Enhancement: Tarrant Mechanical can install energy recovery ventilators (ERVs) or heat recovery ventilators (HRVs) for better airflow and energy savings.
If you notice these issues, it’s time to have your system checked.
