"I'd give zero stars if I could. Called to get a drip fixed and was told it'd be about a week out, which we decided we could live with. Since this is an active drip, we've been managing by using a bucket and turning the main water valve off when not needing to use water. ON THE DAY OF OUR SCHEDULED APPOINTMENT, they called and said unfortunately another job was running over and they needed to reschedule our service. I figured it'd be the next day or at most 2 days... Nope, they told me it'd be 10 more days before I could be fit in due to their other commercial jobs that they can't change. Had I known I'd be cancelled on day of I could have had a half dozen other plumbers come out. If they can't reliably serve residential customers, then they should be honest or don't schedule them. If you're looking for residential work, DON'T TRUST the scheduling department of this place."

Consider replacing your gravity furnace when it's over 30 years old, when you experience frequent system failures, or when your heating bills continue rising despite maintenance. Many older gravity systems operate at substantially lower efficiency rates compared to modern alternatives, often 50% to 60% versus the 80% to 98% efficiency of contemporary furnaces.
Replacement also makes sense when your existing system shows signs of deterioration that could affect safety or when professional inspection reveals significant issues.
Most gravity furnace replacements require between six and 12 hours of professional labor, spanning one to two working days, depending on scheduling and complexity. Basic installations with minimal complications may be completed in a single day, while projects requiring extensive ductwork modifications or asbestos remediation will require additional time.
The timeline includes removal of the old system, preparation of the installation area, placement and connection of the new furnace, and thorough testing.
Watch for warning signs, including inconsistent heating throughout your home, unusual noises during operation, visible corrosion or damage to the heat exchanger, and steadily increasing energy consumption. If your furnace requires frequent repairs or if you notice a yellow or flickering pilot light instead of a steady blue flame, these may indicate serious issues.
Age remains a primary consideration—systems over 30 years old warrant replacement rather than continued repair.
Well-maintained gravity furnaces that pass professional safety inspections can continue operating, but they inherently carry more risk factors than modern systems. Potential concerns include less efficient combustion that may produce carbon monoxide, deteriorating components that could create fire hazards, and the possible presence of asbestos in insulation materials.
Modern furnaces incorporate numerous safety improvements, including automatic shutdown features, sealed combustion chambers, and electronic ignition systems that eliminate standing pilot lights.
