High-Performance HVAC™ companies have a unique opportunity to enhance HVAC system efficiency, indoor air quality (IAQ), and customer satisfaction by integrating duct cleaning and duct renovation services within their business model. These two disciplines, though distinct, share complimentary goals and often overlap in execution.
Collaboration between duct cleaners and duct renovators not only improves results, but also increases operational efficiency. How? By leveraging synergies between their respective job tasks. First, let’s define what I am talking about:
Duct Cleaning focuses on the ‘source removal’ of ‘non-adhered HVAC system contaminants and obstructions from the airside surfaces of the ductwork and HVAC equipment. Cleaning improves airflow and indoor air quality.
Duct Renovation addresses duct design, installation quality, and structural or performance issues. These issues include air leaks, poor insulation performance, or structural damage ductwork. Duct Renovation provides measurable improvements in the BTU delivery rate of the HVAC equipment into the space that the equipment serves.
Now, let’s evaluate where service synergies exist between duct cleaners and duct renovators. The first step is to look at the job tasks performed by them.
that teams up with High-Performance
HVAC contractors to provide duct cleaning
and renovation services.
Grilles and Registers
Starting with the return grilles and supply registers, removing and replacing or reinstalling these is common for the duct cleaner. It is an upgrade opportunity for the duct renovator to provide vent boot gap caulking as well as high-performance grille and/or register replacements.
Moving on to the return and supply duct systems, there are several areas of overlap between duct cleaners and duct renovators. These overlaps are based largely on the type of ductwork that’s being serviced.
Flex Ducts
Flexible ducts offer a significant opportunity for both duct cleaners and duct renovators because they are often not installed correctly according to flex duct manufacturer installation guidelines. Often the same types of airflow obstructions that are observed in poorly supported flex ducts will also challenge duct cleaners’ ability to perform duct cleaning activities.
Duct straps make it difficult to ‘jump’ the cleaning tools and air rods over the hurdle without risk of damage to the internal structure and lining of the flex line.
Additionally, and particularly in homes with floor vent duct configurations, it’s common that construction debris, sharp objects, and other larger ‘contaminants’ fall into the floor trash chute’ over time and cannot be safely removed from the flex duct with traditional duct cleaning methods.
