I had lumberjack in to review why my furnace would not stay lit. When Josh came by for a free assessment he determined my old furnace was not safe do to flame rollout and was a serious fire risk. He gave me a quote and was able to change my furnace promptly. He was very professional and able to complete the job in one day. It wasn't an easy install due to the fact that it was an older home and renovated with limited room and access. My home is now more evenly heated with a high efficiency furnace. I would not hesitate to recommend them to anyone.
