We have more used furnaces that are in good condition. They are all natural gas, 8-10 years old. Asking $300 firm, pick up only. We will install it in London or close surrounding area for an additional cost. If you have any questions ask John any time after 4 pm or all weekend long at 519-672-0400. Our email isn't monitored after 4pm during the week or on the weekend so if you require an immediate answer call John at the number in this ad.
