Q: Do all gravity furnaces have asbestos?

• <div><p>No, but it&rsquo;s common that they do. Gravity furnaces weren&rsquo;t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn&rsquo;t until later that we became aware of just how carcinogenic and dangerous asbestos could be.</p></div>

Q: What factors affect testing costs?

• <div><p>Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.</p></div>

Q: How long does it take to get results from asbestos testing?

• <div><p>Testing and analysis take 10 days to 2 weeks. Expedited services are available for urgent situations typically requiring higher fees.</p></div>

Q: How can you tell if old flooring has asbestos?

• <div><p>You can tell if old flooring has asbestos if thick black flooring adhesive is underneath the tiles. However, homeowners should not cut into linoleum floors to look for this adhesive. Instead, hiring a specialist to test the floors is the only safe way to determine if old flooring has asbestos.</p></div>
