Common Indoor Air Quality Repairs in the Taunton-Raynham Metro Area
Most indoor air quality systems run reliably for years; however, they can develop trouble, especially if they’re not properly maintained. Here are the most common indoor air quality repairs we can handle.
- Leaky or Damaged Air Ducts: Cracks or gaps in ductwork can let in dust, mold, and pollutants. Sealing or repairing ducts improves airflow and keeps air clean.
- Clogged or Dirty Air Filters: Overdue filter changes reduce system efficiency and allow allergens to circulate. Replacing filters is a simple but vital repair.
- Malfunctioning Dehumidifiers or Humidifiers: When these systems malfunction, humidity levels can fluctuate, leading to mold growth or dry air discomfort. Repairs restore proper moisture balance.
- Blocked or Contaminated Vents: Vents that are clogged with dust, debris, or even mold can lower air quality. Cleaning or repairing vents restores safe airflow.
