Air Duct Cleaning FAQs
Air duct cleaning is the process of cleaning the components of the heating and cooling system (HVAC). Typically, air duct cleaning includes the systems:
- Supply and return
- Air ducts and registers
- Grilles and diffusers
- Main trunk line
- Fan motor and fan housing
- Air handling unit housing
Potomac Services provides a full system air duct cleaning for one flat price. We won’t nickel and dime you. It’s just not fair and it’s not our way. Beware of the $89-$159 whole house cleaning deals. You will end up paying more with them then you would with us… or end up having to have your HVAC system cleaned again in a year.
Frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Some of the things that may lead a home owner to consider more frequent cleaning include:
• Smokers in the household.
• Pets that shed high amounts of hair and dander.
• Water contamination or damage to the home or HVAC system.
• Residents with allergies or asthma who might benefit from a reduction in the amount of indoor air pollutants in the home’s HVAC system.
• After home renovations or remodeling.
• Prior to occupancy of a new home.
The most effective way to clean air ducts and ventilation systems is to employ Source Removal methods of cleaning. This requires a contractor to place the system under negative pressure, through the use of a specialized, powerful vacuum. While the vacuum draws air through the system, devices are inserted into the ducts to dislodge any debris that might be stuck to interior surfaces. The debris can then travel down the ducts to the vacuum, which removes it from the system and the home.
The amount of time it takes to clean a residential air system depends on many variables such as the size of the home, the number of systems, the extent of the contamination and the number of air duct cleaners performing the job. When you setup the appointment with the Potomac Services representative, they should be able to give you an estimate time based on the information you provide for the quote.
The best way to determine if the air duct cleaning was effective is to perform a visual inspection of the system before and after cleaning. If any dust or debris can be seen during the visual inspection, the system should not be considered cleaned. While you can perform your own visual inspection using a flash light and mirror, a professional cleaning contractor should be able to allow you better access to system components and perhaps the use of specialized inspection tools.
