Air Duct Cleaning in Davison

Air ducts are essential to everyone because they are used in heating and cooling systems. Unfortunately, dirty or clogged air ducts can cause health issues such as allergies and asthma, so they must be cleaned regularly. Even though it's something everyone wants, cleaning the air ducts is only sometimes at the top of our to-do lists because everyone is so busy. Approximately how long does duct cleaning take? This article offers some helpful information.

Factors That Influence Air Duct Cleaning Time

Several variables affect how long does an air duct cleaning take. Most notably, it is determined by the size of the HVAC system, including the length of the air ducts and the number of integrated components. Here is a summary of the most critical factors:

HVAC System Dimensions

Cleaning the air ducts of an HVAC system typically takes three to seven hours, depending on its size. Comprehensive air duct cleaning for small properties under 3,000 square feet usually takes three hours. Air duct cleaning for more significant properties than 3,000 square feet takes between three and five hours.

The Number of Attached Components

Air ducts have several components that must be cleaned, including:

  • Vents
  • Registers that are returned
  • Filters
  • Furnace
  • Coil for air conditioning
  • Covers for ducts

Wiping the dust and debris off the furnace, air conditioning coil, duct covers, vents, and return registers are part of a thorough air duct cleaning. Cleaning or replacing the filters is also required. Cleaning more of these air duct components would, of course, take longer. 

Air Duct and Vent Cleaning

Commercial Or Residential

Property setting and property size influence how long does it take for air duct cleaning. Cleaning a commercial property's HVAC system typically takes longer than cleaning a residential property.

The difference in cleaning times between commercial and residential duct cleaning is usually due to the accessibility of the HVAC system. Professionals cleaning the air ducts of a residential HVAC system should be able to work primarily uninterrupted. In contrast, those working on an HVAC system usually have to be discreet, slowing their progress. It's also worth noting that commercial buildings typically have larger and more complex HVAC systems than residential buildings.
