Online review platforms are one of the best ways to gather information about any service company. In these platforms, people write about their experiences with the service company, and as a result, you can have a clear idea of what to expect from a specific service company.

Besides, when companies use chemical biocides for mold cleaning, they charge extra money.

3. Check Certifications

3 Signs of Good Air Duct Cleaning Service

1. Duct Interior is Free from Dust

Select a random return and supply register in your house. Now, remove the cover from the supply register and return. After that, use a torchlight and check inside. If you find any dust inside the supply register and return, air duct cleaning is incomplete, and tell your service professional to clean the air ducts again. But if you don’t find any dust inside the register, your air duct cleaning service is excellent.

2. Clean Vent Covers

During an air duct cleaning service, a professional cleaning technician will remove the vent covers and replace them with new ones. If the vent covers are dirty, it means that the service professionals haven’t cleaned the air ducts properly and require recleaning the air ducts.

3. Air Duct Cleaning Professional Will Cut a Small Hole in the Air Ducts

Usually, professional air duct cleaning technicians cut a small hole in the air ducts to clean the ductwork thoroughly. When the air duct cleaning is done, they seal the hole in the air ducts.

If the professional air duct cleaning technician didn’t cut a hole in the air ducts, there is a high possibility that your air ducts are still dirty. Again, if the holes aren’t sealed properly, treated air will leak through them and cost you extra money on utility charges.
