York Furnace Overview

Furnaces use fuel, often gas, to heat outdoor air and circulate it within the house. The efficiency of these devices is calculated on the basis of how much gas energy is translated into thermal energy for the house. This ratio is called Annual Fuel Utilization Efficiency, or AFUE. The higher the AFUE, the more efficient the furnace.

York produces three different lines of furnace, each of which has an indoor and an outdoor component. Most of these models have received EnergyStar ratings and Good Housekeeping Seals.


These furnaces are single stage, which means they are either off or operating at full blast. The two Latitude models — TG8S and TG9S — have rather different AFUE ratings: 80 and 95.5, respectively. The TG9S receives an EnergyStar certification due to its efficiency.

They are relatively compact at 33″ high. They also both use constant blowers and operate quietly.

 [ York Series :  ]


The York LX series contains six models: TM9X, TM9V, TM9T, TM8X, TM8V, and TM8T. These all have similar features. The TM8 furnaces have AFUE numbers in the 80s. The TM9 series has AFUEs of up to 96.

Some of the models are two-stage, which means they can operate at reduced power when not much heating is necessary; this addition saves energy and decreases noise on milder days.

The heat exchanger in the LX furnaces consists of a tube made from aluminized steel. The units can also be equipped with external air filters to increase air quality. Another optional feature is ClimaTrak®, a cybernetic system that controls the device with climate-based predictions.


The York Affinity series has both low- and high-efficiency models. YM8M and YP8C have AFUEs of only 80. YM9M has an AFUE of 97. YP9C goes up to 98. Both of these figures are quite high; recall that they represent the percentage of energy inputted that ends up directly heating the house. These models are more efficient in part because they start and stop less often.

YP8C and YP9C both use variable-speed blowers to improve efficiency. This simply means that they can operate at different speeds, commensurate with how much heat they need to deliver.

ClimaTrak, comes standard with the affinity models; this device will predict temperatures and adjust operating accordingly based on the climate of the home’s region.

All four Affinity furnaces allow users to adjust the desired temperature in tiny increments, and maintain indoor temperatures within 1/2 a degree of the thermostat setting.

Diamond Series

York’s two-stage furnaces are marketed as the Deluxe Diamond 80 and the Deluxe Diamond 95. Their single-stage series are the G8C Multiposition, the Diamond 80 and the Diamond 90.

Care and Maintenance

Best practices around furnace maintenance mean having it inspected on an annual basis. A good service agreement with a qualified technician can help prevent faulty functioning and energy inefficiency.

Many homeowners change their filters on their own.


The Affinity furnaces come with lifetime warranties on their heat exchanger and ten-year warranties for their parts. All other models have twenty-year warranties for their heat exchangers. LX has a ten-year parts warranty; Latitude has a five-year parts warranty.

For any of these warranties to be fully valid, the consumer must register her product within ninety days of purchase. Otherwise, the warranty will be shortened!

"Contractor fail"

5.0 rating
Very Satisfied

I have been selling and installing York/JCI equipment for decades. We have installed thousands, and as an authorized dealer, we are trained by the factory and stay on top of all the new equipment install requirements. Our warranty program is in two parts. 10 year parts, which does not include labor costs, and then part two is offered at a small additional charge, which includes parts, labor, and anything else needed to make the repairs or replacement of the faulty equipment. When installed properly, these unit simply do not have problems. Out of over 5,000 systems we have had 4 actual warranties, which is an unheard of low percentage industry wide. Each contractor is obligated to explain the system warranties and what is available to them to be sure to have all the correct information. Each review I have seen on this system is of issues that were avoidable if installed or managed correctly by the dealer. True York dealers that do the job right just don't have these issues.

"Condensate unit of furnace"

2.0 rating
Somewhat Unsatisfied

This is the second York furnace that has been installed. It's a single stage TM9E060B12MP11. I am getting something else from the furnace that causes me to get dizzy. The last furnace, I used an air quality monitor from the health unit and it showed up Nitrogen Dioxide on one of the readings, which was unexpected. It was then that the furnace was replaced. Now, I am having the same problem with this second unit that has been installed. I am getting dizzy again and feel better if I open up the windows and doors. I am wondering if the condensate unit inside the furnace is faulty in some way, i.e. seals and they are not expelling the condensate properly and it is getting into the heat exchanger area. Is there anyone that can help?

"Excellent furnace"

5.0 rating
Very Satisfied

My furnace installation went as smooth as could be for having my whole unit die a few days after Christmas. It's quiet and efficient, and seems to be working out beautifully. It's heating my 2600 square foot home that was built in the 1860s. My bill has not gone up at all and I turned the thermostat up higher than I had it before. The unit is much much smaller than my old one too, which is a nice bonus. I'm very happy with the financing and payment schedule offered also.

I was surprised and disappointed to find how low an efficiency rating the unit has.
