Should you clean your HVAC system?

In short YES!
The EPA recommends cleaning air ducts whenever there is a rodent/insect infestation, mold growth, or if the ducts are clogged with dust and debris.
We don’t recommend a remediation without a through cleaning of all Heating and Air conditioning components after the materials removal and other remediation work is performed.
The conditioned air system in your building is truly the “Lungs” of the building. Airborne particles can be released from dirty ducts and contaminate a HVAC system, or if moisture gets into the system mold can grow, and mold spores may be released into the air. In those situations, it’s crucial to have your facility’s ducts cleaned.
Dirty ducts can become a breeding ground for mold spores, bacteria and other particles, which can lead to poor indoor air quality.
We know from the information provided in our past posts about indoor air quality (IAQ) such as the 4 Reasons You Should Clean Your Building’s Air Ducts that poor IAQ can affect the health of occupants.
Duct Cleaning Companies
If your home or office is faced with a dirty duct problem, and you have to hire an air duct cleaning service, what should you expect from the company? The EPA offers a list of expectations, so you’ll know how to verify that your provider offers a quality service.
The duct cleaning service provider should:
1. Open all ports and doors to ensure the entire system is thoroughly cleaned and inspected.
2. Be sure to inspect the system before cleaning to look for asbestos-containing materials (insulation, etc.). Such materials should not be disturbed and should only be removed by contractors who are specially trained in asbestos removal.
3. Use a vacuum that will exhaust particles outside of the building, or use a HEPA vacuum to contain particles.
4. Protect furnishings and carpeting throughout the cleaning procedure.
5. Brush duct surfaces as well as use contact vacuum cleaning to remove all dust and particles.
6. Protect the ductwork by sealing and re-insulating access holes and use soft-bristled brushes to clean fiberglass duct board or metal ducts lined with fiberglass.
Use the NADCA‘s air duct cleaning standards and NAIMA‘s practices for ducts containing fiberglass.
After its all said and done…… get the system scoped
We have invested heavily in the technology that allows us to travel inside your supply and return ducts to view conditions within them. Our camera system allows us to capture both before and after images, both still and video, to document effectiveness, or lack thereof of the duct cleaning activity.
