"Noisy and unreliable York gas furnace"

1.0 rating
Very Unsatisfied

We had installed a York TG9SMP gas furnace in our rental house approximately 5 years ago. Within 1 year of having this furnace installed, this unit puked water all over the attic of the house (it could do this because it was a “high-efficiency condensing” model). We were extremely lucky that we caught this problem before it ruined the ceiling in our house. Our installer evaluated the problem and determined that it was due to a defective/ cracked condensate collector. This was very likely a problem that Johnson Controls knew about, but did not bother to contact the customers who had purchased this defective product so that they could get the furnace checked and have that defective part replaced so that they could avoid potentially serious damage to their home. In addition, two out of two tenants who have rented this house have complained about the noise of the furnace. Our installer told us that that this “high efficiency” furnace is just noisy. When our second tenant strongly complained about the fact that you can hear this furnace “3 houses” down the street, we realized that we were simply going to have to replace this piece of junk with a reliable and quiet furnace. It cost us a lot of money to have this furnace installed and now (5 years later) we are forced to replace it. Needless to say, we would never consider a product by Johnson Controls. In contacting Johnson Controls about what I consider to be major issues with their product, it is apparent that they simply don’t care. A 2012 article in Consumer Reports labels York as one of the least reliable gas furnaces.

"York forced hot air furnace"

5.0 rating
Very Satisfied

Overall a very efficient unit with good heat output. A separate energy audit put the units efficiency rating at 99.0%. In my particular installation, I think that the installer should have offered the option of using “hard piping” in the distribution system instead of using soft tubing. The extra cost would have made the overall appearance and air distribution much cleaner and efficient.

"York furnace"

5.0 rating
Very Satisfied

I purchased a new York from Proair Heating and Cooling (Steve Genn) in Salmon Arm a couple of years ago. I have had excellent service from them. The furnace replaces a very old furnace and has made a big difference to my heating bill. I would highly recommend York furnaces and the company who installed it.

Seems to run well. Most equipment is the same, but the big difference is the contractor and his crew- they were good, friendly, clean, and price was competitive. What more could you ask for?

"Great unit at great price"

5.0 rating
Very Satisfied

Due to system (a/c) failure of our 11 year-old Trane system, we installed a new York furnace and a/c (Model ycjf). Both are more efficient than our old builder unit and the furnace has a large blower to move more air up to the second floor from the basement. Although it was just installed today, so far so good. The a/c unit is so quiet. The furnace is a bit more loud, but I think it is the duct work due to more air moving through it. Love the 10 year warranty on both units and lifetime on the burner on the furnace. That gives me some piece of mind. I would use the same contractor and buy the same equipment again.

Other TG9S Reviews

In general, reviews from around the web praise the York TG9S for its affordability, energy-efficiency and performance. A few problems are reported on consumer forums, however. Among them, one homeowner on hvac-talk.com complains about the noise produced by the unit after it was installed. As it turns out, there was a glitch during the installation and the piping wasn’t run outside as it should have been. Other contractors on the forum suggest that adjusting the pressure also may help to cut down on noise.

A consumer asks on hvacmechanic.com for advice on how to keep burners on his newly installed TG9S from going out every few seconds. Upon further inspection, he finds that condensate collection unit has a leak that could be damaging the thermocouple. Contractors on the forum encourage the homeowner to report the problem to the installing technician, rather than the manufacturer.
