"Dave contacted me by phone in response to my request for a quote. He told me what the cost would be, and that is what I was charged when the job was completed. The price was very reasonable. He was professional, courteous, and showed up on time. He did a great job getting out duct work cleaned out and communicated with me at the end about what he found. I'd recommend this company and will use their services again."

Air Duct Cleaning questions, answered by experts

According to the EPA, it’s not considered necessary to clean air ducts except on an as-needed basis. Issues that warrant cleaning include poor airflow, reduced energy efficiency, and odd odors or noises emanating from the ducts. Of course, regularly cleaning air ducts will only improve their performance and ensure no sudden issues arise. The National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every three to eight years for efficiency and durability.

How often you change the filters in your return air vents typically depends on factors such as your indoor air quality, the type of filter used, and the specific needs of your HVAC system. Generally, checking your filters every 1-3 months is recommended. However, if you have pets or allergies or live in an area with high dust levels, more frequent replacements may be necessary. Regular filter changes ensure that your HVAC system operates efficiently, maintains good indoor air quality, and extends its lifespan.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

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.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.
