"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"$80 service call and a 500% markup on parts? That’s excessive. I completely understand that businesses need to make a profit, but being charged over $500 for a 20-minute visit is more than what many highly skilled professionals—attorneys included—earn for their time. Before scheduling the service, I asked for a quote on both the part and labor. Unfortunately, I was told they couldn't provide that information in advance (which, in hindsight, should’ve been a red flag). I trusted the positive reviews and moved forward anyway. When the technician arrived, they spent about five minutes confirming what we already knew: that we needed a specific part. We expressed concern about the cost, and a manager offered a modest discount, which we declined. We ended up paying the $80 just to be told exactly what we had already suspected. Afterward, we contacted another company that provided the part at cost ($100) and completed the service for $135. Bottom line: if you're trying to avoid unnecessary expenses--which I think right now most people are, it’s worth calling around. I’d recommend saving yourself the service call fee and going with a company that’s more transparent from the start- one that respects your time and your wallet."

FAQs for heating and furnace service projects in Gainesville, GA
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.
