Frequently Asked Questions for Professional Air Duct Cleaning

Why is cleaning air ducts necessary?

Indoor air quality issues affect approximately 25 million people in the United States. Just like your shelves, baseboards, and floors, your air ducts get dirty and contaminated. Cleaning air ducts and vents improves your indoor air quality while increasing the efficiency and lifespan of your HVAC equipment. Contaminated air ducts are a leading cause of issues with allergies and asthma. Visit our air duct cleaning page to learn more.

How long does it take to clean air ducts?

The amount of time it takes to clean your ducts depends on factors such as the size of your home, the number of furnaces, number of vents, and accessibility to supply and return systems. On average, it takes 3-4 hours, but it can vary. We always take our time to ensure the best results.

What are the major benefits of cleaning my air ducts?

Cleaning air ducts offers several benefits, including improved indoor air quality, a reduction of dust, and an extension of your HVAC system’s lifespan.

What kind of equipment do you use?

Using the best technology and most powerful equipment is equally as important as knowledge and expertise for achieving excellent results. Many companies use substandard and inferior equipment that is unable to effectively clean air ducts. Cleaning air ducts requires very powerful and expensive vacuum equipment. Zeppelin uses large custom-made vacuum trucks from Pringle, the leading producer of air duct cleaning equipment in the country. To learn more about their equipment, visit

How are air duct cleanings priced?

We pride ourselves on transparent and flat-rate pricing. All prices are listed on our online reservation system. BEWARE of companies offering prices that seem too good to be true. Proper air duct cleaning and dryer vent cleaning require expensive equipment and sophisticated knowledge. Too often, we have witnessed very poor results in homes from a “low-cost” provider.

How often should I clean my air ducts and vents?

We recommend cleaning your air ducts every 3 years. However, it’s advisable to clean them more frequently if you have pets, have recently undergone construction projects, suffer from asthma, or have allergies.

Do you clean up after yourself?

Absolutely. Our goal is to “leave it better than we found it”. We will vacuum, dust, and wipe down surfaces to ensure your home looks great.

How powerful are your vacuums?

Our trucks have 15,000 CFMs of suction power. To put that into perspective, your average shop vac has 75-100 CFMs. So our truck is as powerful as 150 shop vacs!

Will duct cleaning reduce energy or utility bills?

Blocked air ducts due to dust or debris can increase your utility bills and impair your vent system and HVAC components, such as the evaporator coil and blower. The accumulation of these contaminants in the furnace can restrict airflow, forcing your HVAC unit to work harder and driving up energy consumption. Cleaning the entire HVAC system will increase efficiency and extend the unit’s lifespan.

Do you take before & after photos?

Absolutely! Our technicians will share all the photos with you.
