"They did not have to dig a trench around my house. They used a machine to inject chemical into soil.

I use this company for my Qtrly pest control also."

Air Duct Cleaning questions, answered by experts
Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.
Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home.
You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.
The EPA recommends duct cleaning only as needed—meaning routine cleaning is unnecessary. But if you suspect mold or other contaminants in your ductwork, consult a local professional to determine the best next steps.
Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.
When you insulate ductwork, you help protect the air moving through the system from external conditions and keep it sealed within the ducts. This makes your HVAC system more efficient since it doesn’t have to work as hard to heat or cool your home. Insulation can help lower your energy bills and prevent problems like condensation and mold formation inside your ducts.
The primary drawback to cleaning air ducts is that you could damage the HVAC system or the ductwork. If you damage a seam or knock a section loose, you could allow heated or cooled air to escape, which costs you money through reduced system efficiency. It can also be a time-consuming process to clean air ducts if you have a large home or complicated ductwork layout.
