HVAC Maintenance

Unpleasant odors coming from your air conditioner can make your living space uncomfortable. Understanding the causes and taking the right steps can eliminate these bad smells and keep your home fresh.

1. Dirty Air Filters

Clogged or dirty air filters can trap dust, mold, and other debris, causing unpleasant odors when the AC is running. Regularly replacing the filters can solve this issue.

2. Mold or Mildew Growth

Excess moisture in the AC unit can lead to the growth of mold or mildew, which emits a musty smell. Cleaning the evaporator coil and ensuring proper drainage can help.

3. Dead Animals

If small animals like rodents or insects get trapped inside the AC ducts, they can cause a foul smell as they decompose. Regular duct cleaning can prevent this issue.

Key Factors to Consider

  • Change air filters every 1–3 months.
  • Schedule professional cleaning of the AC unit annually.
  • Ensure the AC unit has proper ventilation and drainage.

Conclusion

Bad smells from your air conditioner are usually a sign of poor maintenance or hidden issues. Regular servicing and cleaning can prevent odors and improve indoor air quality. Contact Repair Boy for expert AC maintenance and repair services to keep your home comfortable and odor-free.
