HVAC Remediation and Duct Cleaning

  • Commercial and residential HVAC services

  • NADCA Certified Technicians

  • Mold impacted HVAC system remediations

  • HVAC duct work cleaning

This service is only offered when combined with a mold remediation, i.e. a home's HVAC system resides in the basement where a mold issue exists.

Dust is everywhere all the time. Regardless what type of HVAC air filter used, over time your ducts are likely to look like the left side of the above photo or worse. Every indoor air environment is different and subject to different factors contributing to the the dust and debris that builds up within the ductwork. In certain instances mold can impact the ductwork as well as the system itself. We specialize in duct cleaning, sanitization and remediation.

The cleaning of Heating, Ventilation Conditioning (HVAC) systems is important for indoor air quality. Good system maintenance should be routine and a service contract with your HVAC company should be at minimum twice per year at the major seasonal changes.

The HVAC system and related duct work can harbor mold growth and bacterial growth if moisture is not controlled. This is especially an issue if occupants have sensitivity to mold growth or have been diagnosed with health issues related to immune system deregulation causing significant symptoms.

During inspections of properties where mold exposure is a concern we will often evaluate the HVAC system to see if there is any indication of mold growth in the Heating or Air-Conditioning portions of the system. The combustion process in highly efficient systems can generate some moisture which is often removed from the system via the condensate system. On occasion that system does not do an adequate job of removing the condensation which can promote fungal and bacterial growth within the unit itself. During the summer months, which are generally more humid, the air-conditioning system is likely to lead to more moisture at the cooling coils during the cooling of the refrigerant. Again, the condensate system is designed to remove that moisture and eject so it does not present a environment promoting fungal or bacterial growth.

Dust, usually composed of skin cells, along with other matter that gets past the filter system or comes from the stud bays or joist bays where the dirt and debris can move through the system after the filter. In most residential building the returns are not ducted, but rather are simply poorly sealed open bays behind walls or under floors. If moisture is introduced in those spaces problems can arise.

If we find a home with mold issues evident we will often recommend duct cleaning and in an older home we may recommend duct sealing with Aeroseal Duct, which seals the supply side of the system from the inside. New construction has duct sealing requirements and pressure testing of the system, but in older homes, this was not a requirement and the U.S. Department of Energy estimates that anywhere between 20-40% of the conditioned air you pay for does not reach its intended destination. That is why you may have a room that in the winter is cool or in the summer it is hot.
