"ACS installed a new Bryant heat pump + furnace. The equipment is high quality and the team was knowledgeable, flexible, and willing to answer all my questions. They accommodated a change in scope on the day of install from just installing a heat pump to installing a furnace + heat pump combo. This set the team back a few hours for the last minute parts request, but they powered through a very long day and stayed until the job was finished. All customer service goes directly through the owner operator. Originally this seemed like a plus, but I think they would benefit from support staff. I needed to edit and downgrade this review after a few negative experiences. Some changes are related to issues noticed after the install. The unit was not secured to the pad outdoors and also was not attached to the house. Holes cut into the corner of the garage slab in order to pass through the lines were not patched, leaving a break in the envelope. Mark promised to follow up on both of these, but he did not send anyone out to take care of this. Mark also directly promised that our install would qualify for Energy Trust of Oregon incentives for $3000, when in fact it is clear after speaking directly with Energy Trust representatives that our install did not qualify for any amount of rebate. This promise was echoed throughout the quote and the install process. I believe that the lack of a support staff is causing some shortcutting or disorganization when it comes to managing some of these details - I would prefer to assume that ACS did not know the details of the incentive rather than that they purposefully deceived me, but I dont feel comfortable recommending them given these circumstances."

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.
