"The company answered my query within an hour after I submitted it through the site. They dispatched someone in an hour. Both were big pluses. The tech inspected my breakers, the A/C outside, and the air handler in my attic. He found a sensor was being tripped due to water buildup in a line? Why hasn't this happened once since I bought the A/C unit 5 years ago I wondered. The tech fixed the sensor and left. $170 or so. The same problem happened within a month. I called again. They dispatched someone else via text. Then shortly after they dispatched the same guy Matt that "Fixed" the sensor the first time. He checked it, disconnected it, and left it hanging down from my attic door. He said he'd need some nitrogen to blow out a line due to water build up and fix the sensor again. I never heard from him or anyone else again. The follow up from this company is non-existant. Also the "water issue" I found out was not a real problem from the 2nd company called."

"The tech came out and said he had to put Dye in my unit that was down so he could find the leak . My one unit was low on refrigerant and had to put dye in than he added 3 pounds of refrigerant . He charged me $1,373.00 for this . Total rip off . I called my friend who runs a HVAC company and had him look at my one unit that Goettl serviced . There was no dye present in the system put in .The dye cost was $1,100.00, My new tech found the leak right away it was the coil outside that was leaking refrigerant and no dye was present it was just the oily refrigerant and found the leak immediately. So I got ripped off as the Goettl tech charged me for this and never put dye in the system. The tech checked the coils in the attic so he said . My tech checked the coils and took a picture of the plate that covers the coils and the screws still had the plastic over the screws so he lied about that because he did not even take the screws off to check it . I have a picture of the plate cover which he did not take off because the screws were still sealed with the plastic on them. So the Goettl tech lied to me about that also. So I got charged $1,373.00 for dye that I did not get , lied about checking the coils in the attic, and did not even check the coils in the unit outside . My tech has pictures , found the leak outside right away with the refrigerant leaking with no dye in it . So Goettl totally ripped me off $1,373.00 dollars . I would not use Goettl ever again . My friend who is in charge of HVAC in a business says the dye only cost him $90.00 to buy and I get charged $1,173.00 by Goettl for a service I never received . My tech said he did not need to use dye as he found the leak in the outside coils immediately on inspection . Goettl totally ripped me off and Iâ m fighting the charge as terrible service ."

FAQs for heating and furnace service projects in Gilbert, AZ
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.
