Overview of TG9S

Standing at only 33 inches tall, its compact size was designed for installation in areas such as attics, closets and basements. The TG9S boasts a 95.5 percent AFUE rating. It features tubular aluminized steel heat exchanger and a constant speed blower that translates into consistent air distribution indoors. The configuration is multi-position with a PSC fan motor and single-stage burner.

Best Value High Efficiency Furnace

The York tg9s is the best value high efficiency furnace in the line. This 95 afue furnace provides operating efficiencies that only a few years ago cost much more to achieve. The compact size makes it an ideal replacement furnace, and the fact that one furnace can be installed horizontally or upflow or downflow is a bonus, too! While many consumers really like the 95 afue advantage, they find the price point of this model to be perfect for a growing family's budget. Consumers are also surprised at the affordable additional YorkCare plans that can offer years of additional protection.

Unit is fine - installers not

Our York hvac unit has performed well. However, the installers, Anytime Heating and Air in Jeffersonville, Indiana, did not provide the customer booklets so our registrations were submitted 16 months after installation. This error has reduced our warranty from 10 years to 5 years. As a professional who submitted all other warranties in a timely fashion upon moving into our new construction January 2016, I am not not pleased with the lack of professionalism in providing the booklets. The booklets were located, hidden out of sight, when routine maintenance was done.

Problems in less than 2 years

My furnace was installed less than two years ago and performed well until recently. The problem involves the furnace shutting down for no apparent reason. The control board indicates a ventilation problem but none exists. This erratic shut-down problem (malfunctions) is described in multiple posts on the Internet and indicates a serious problem with the York tg9s furnace and its lack of reliability. I am distraught that I have purchased this unit and do not look forward to suffering the continuing maintenance nightmares so aptly described by other owners. I would not recommend purchase of this furnace based on my experience and the reported experiences of others.

York Furnace TG9S Review

This winter our 10 year old TempStar furnace failed. It was going to be quite expensive to repair. We took the contractor's (c&c Olympic) recommendation to replace the unit with a new York furnace. The contractor also carried Trane furnaces, but given the tight space for our installation, the contractor told us to go with York. We did and so far the furnace has provided excellent heat service. No problems to speak of currently. It is a 95% efficiency furnace.

New furnace review

This unit is much smaller than the previous furnace. It heats the house very evenly and it runs very quiet. I am hopeful that our heating bills will be reduced throughout the winter.

My old furnace was working but was over 30 years old, inefficient and needed replacement. I wanted a high efficiency gas furnace which would qualify for a $600 rebate offered by my utility company since I am retired and on a fixed budget. I had good success with a local contractor in the past and when I requested bids on a new heat and air system he was substantially lower than his competition. He recommended York and I went with his suggestion. It's quiet, efficient, does the job and looks great. No regrets.

Would not recommend this furnace

I bought this furnace in 2013 and I have lost track of the countless times we have had to have someone come out and fix it. It wouldn't fire up right and often times blew cold air. It would be taken care of for awhile just to have it blow cold air again. Then it started back burning and not lighting right so the entire insides were rebuilt with burners, burner box and other internal parts. The very next day it was just as bad as before. I hate this furnace and it has been nothing but a nightmare and I would not recommend this furnace to anyone.

Affordable Furnace

My York TG9S is by far the best furnace I have ever owned for the price I paid for it. The unit is incredible and the price can't be beat. This unit produces and provides a high level of comfort and heat output. It has a constant speed blower which is really efficient. It is constructed in a very sturdy manner and I have no complaints about the way it looks, feels and sounds. High quality all around. Again, the price of it too is really incredible. After finding the York TG9S furnace during my search I was really impressed. At 33 inches this furnace unit isn't too tall and does not require a lot of space. This was great for me. I would like to recommend this brand and model to others. I went from being someone who was skeptical at first to someone who is now a very satisfied customer!

Replaced older furnace with York

Our older natural gas furnace had been in our house since prior to our purchase in 1987. The unit had been reliable but was old and finally called it quits in April 2014. We decided to go with a York high efficiency unit. It was installed in July 2014. Little did we know that we would experience one of the coldest winters in Vermont on record. We experienced a record number of sub zero days along with frost that reached to the deepest levels in anyone's memory. Our entire city was asked to run a pencil width stream of water in at least one faucet. Given the record cold we used 15 CCF more of natural gas as compared to our previous low consumption that was a result of a much warmer winter. We had read the advertising literature about potential fuel savings but we actually experienced it for ourselves. The savings are real. The $$ left in our pockets is real.

Made in USA

I replaced my 35-year-old furnace with a York furnace because of the warranty and the quality of the unit that I purchased. Also, a very important feature to me is that it is made in the USA. As other future purchases are made by me, most likely a York A/C, I will be helping to keep jobs in America. Thank You York!

Noisy and unreliable York gas furnace

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

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

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

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.

Choose Something Else

York furnace ran well for a couple of winters and then the condensate collector box leaked all over and ruined a good portion of the furnace. With that said, York- so far- has been reasonable to deal with. Paid a lot of money for something that really isn't very well made. We rely on our heating equipment in Vermont, and York is just not very good quality. Pay now or pay later- you will pay for a York more than once! Be warned!

Residential furnace, 85% DIY

Read a review that this unit was an easy diy project if you are mechanically minded to any degree. True. Installed all but the gas conversion to lp and the gas hookup. Paid a local contractor to inspect installation and do the gas work. Took me at least 3 times as long as a contractor would have taken but he would have cost over $85 per hour to install. Instructions were easy to follow. Works great!

Fox Bothers Rocks!

Had a new York furnace installed in my 132 year old historic home and Dustin and his crew did an excellent job. I would highly recommend Fox Brothers Mechanical and York furnaces to all my friends who are looking for a quality furnace and excellent installation.

"High Inefficiency"

Our York furnace and AC unit are complete crap boxes. We had an old Trane that worked but I was trying to save ENERGY/lLOWER my carbon footprint. I did because the units never work. Every part of the heater has been replaced, some twice. Give me a new York unit and let's call it a day. Better yet, give me my old Trane back!

Things keep breaking

I bought my york furnace 2 1/2 years ago, I had some minor adjustments that the installer took care of. but the install is now out of buisness. Last January the capacitor and limit switch had to be repalaced to the tune of $300+. And now a year later I get up in the morning and the temperature in the house is 51. So I call my hvac guy and several visits later I have to have the low and high pressure switches replaced, which but to the grace of the hvac guy would have been $550. I don,t understand how a furnace that is only 2 1/2 years old should have this many problems.

Residential gas

Furnace was installed in the summer of 2010. The condensate pan developed a leak in the winter of 2012, causing flooding of the furnace room. The fan broke down a few weeks later and we were without heat for several days during the coldest snap of the end of the year. Parts were covered by the warranty, but labor was not. We paid our HVAC contractor $300 to get the furnace repaired. Obviously, we are very dissatisfied with the product and would neither buy that brand again or recommended it to anyone.

I agree, York is a piece of crap

Had furnace installed just over 2 years ago, woke up yesterday to no heat. Had repairman out and he got it started, said it was a faulty wire. Woke up this morning, no heat again!! Should have read these reviews first.

It's hard to stop a York.

I have had a York furnace for ten years and not one problem. Thinking about going with a hig effiency unit and will probably go with York.

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 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 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.
