Asbestos is a health risk for lung disease which is why HVAC is so important to have testing for asbestos. The air you breath inside your home or business is from your ventilation system and can have a serious risk to health if you have an older property. Asbestos was commonly used in HVAC products, vents and duct connectors because of its fire and heat resistance. Many heating contractors may not know how to identify asbestos which can cause these dangerous fibers to be released into the air or may stop the renovation project to call in a certified asbestos company to inspect and test for asbestos which can increase expenses and delay the completion of the project.
Asbestos found in older heating ducts systems was most commonly used in the cement, insultation, tape wrap, and cloth in and around heating ducts and lining. Manufacturers used asbestos a lot in heat ducts because asbestos is heat and fire resistant. In many older properties these heat ducts need replacing or repairs due to age of the system. The heat ducts are used to move air your breathing within your property which is why you should have your heat duct ventilation inspected by a certified asbestos company. Airtite Environmental is fully licensed and highly skilled in identifying, testing and removing asbestos from heating systems and anywhere else asbestos can be in your home or business.
Asbestos was commonly used in HVAC products for its fire and heat resistant characters and strength by manufacturers pre-1990’s. Many heating contractors may not take the necessary measures to avoid disturbing possible asbestos made HVAC products or asbestos used for installations of these products due to lack of knowledge.
Wood Burning Fireplaces and Stoves The paper that is used can contain asbestos for its fire resistance, cement sheets and millboard can also have asbestos. Fireplace embers, logs and ashes used in newer faux fireplaces can also contain asbestos
Boilers Asbestos material was used for both interior and exterior insulation of the boiler. Asbestos can also be commonly found in and around the pipes used to install the boiler system.
Furnaces & Air Conditioning Units Asbestos was commonly used for the flexible duct connectors leading to the unit itself. Oil and coal burning furnaces also were common for having the interior walls built using asbestos materials. If a replacement unit is needed this duct connector needs to be replaced which can disturb the asbestos fibers.
Wall Gaskets Almost every piece of machinery used gaskets for joints and seals. Gaskets need to withstand high heat and compression making asbestos a good choice of material in older machinery. This asbestos made material was used in most HVAC applications and should be inspected before any renovation.
Door Gaskets Fireplaces, stoves and boilers and other metal doors that need to be sealed used asbestos made material for its fire and heat resistance advantages. Old door gaskets can get brittle and need to be replaced which can contain asbestos.
Pipe Insulation Pipes that have an insulation around them in older applications can have asbestos used in the material. Asbestos naturally was a good insulator and is resistance to heat was why many pipe insulation manufacturers used asbestos in the insulation. Pipe insulation cracks or deteriorates over time which can cause the asbestos fibers to become airborne that causes a health risk.
