York Affinity Furnace Overview

York’s Affinity line consists of two gas furnaces: the Affinity YPLC, offering 80% AFUE, and the 98% AFUE Affinity YP9C. Winner of the Consumers Digest “Best Buy” award, the 98% AFUE YP9C is Energy Star rated and has a multi-position configuration.

Both the high-efficiency and base-line unit use a variable speed EMC blower motor for quiet, efficient operation and a modulating design that constantly adjusts heating levels for maximum comfort.

Additional components of the Affinity series include: reinforced cabinets, gasket doors, and York’s Climatrak Comfort System, a feature that customizes operation to the conditions of any region. With its compact 33-inch height, the Affinity series can also fit into tight spots around the home.

Along with the current YPLC and YP9C series, there are several discontinued series in the Affinity furnace line, including the Affinity 8.S, with an efficiency of 80% AFUE; Affinity 8.V, also offering an efficiency of 80% AFUE; Affinity 9V, with a 92% AFUE; and the Affinity 8.T.

"Would not recommend"

1.0 rating
Very Unsatisfied

Had 98% effic. Affinity furnace and A/C installed in Aug 2009. Within 2 weeks, had to come back and repair A/C unit not welded properly, leaked all freon out. Late October, had to return and repair furnace. No heat, would not turn on. Now, it would not turn on, had no heat to wake up to. Service tech came after 1pm in the afternoon, repaired the problem and then adjusted the modulator valve or something so that the whole burner would not go on when not needed. So to date, I have used more gas this year than I did last year with a 15 year old furnace. The tech also noticed another problem and has ordered parts.. not very happy after spending $9000.00 Would not recommend.

I bought a high efficiency Affinity. In 1.5 years, we have replaced the inducer motor, pressure sensor, reconfigured vent pipes, replaced mother board and it still fails to work as needed. Have had service out numerous times for $1000 in cost. Will try to replace under lemon law.

Recently had a York yp9 variable speed modulating gas 98% eff furnace installed in my house I can barely hear the furnace running. I have read some of the complaints about others it could be the company that had installed it. These guys were very proffesional clean up after themselves. Someone wrote about the radiator thing that would be your coil which provides your ac in the summer warm air running accross does cause condensation and needs to be clean but I read its like that for all manufacturers. My neighbor is very envious of what I have and may want one of his own now.

"York Affinity"

5.0 rating
Very Satisfied

Last month I had a York (now owned by Johnson Controls) Affinity variable speed furnace installed and it has been a great furnace thus far. The 95-97% efficiency is tremendous and it is far superior to the Rheem it replaced. The variable speed blower/modulating fan allows the heat to be distributed evenly and relatively quietly as the fan is not overworked. The furnace is very quiet, although in the morning when it first goes on after having the thermostat turned to 60 degrees in the night, it is audible, but only for a couple of minutes as the fan is on high. After the temperature set is reached, it is on cruise control, in effect, and is hardly audible as it continually maintains the desired level. The venting is interesting as the carbon monoxide is vented through pvc pipe which is under the house and then discharged through a hole in the wall, while the water is discharged via a small sump pump into the garage sink. The furnace is fine and the noise level is extremely low. The efficiency qualifies for tax credits and it is the best furnace we have owned.

"Do Not Buy York Affinity"

1.0 rating
Very Unsatisfied

I purchased a York Affinity 2-stage furnace from an authorized York dealer in Skokie, il. The unit has never functioned properly. It shuts itself down before bringing my home to temperature. My dealer made more than a dozen trips to my home and never fixed the problems… although he always charged me for the privilege. In 2 years, I have been charged over $1000 in service fees, and my furnace still does not work. After writing a letter to the Better Business Bureau, I received a call from York’s midwest sales manager. He agreed the furnace was a lemon and has agreed to replace it, although with a lesser model that doesn’t even show up in York’s full line furnace brochure. The dealer, however, says he will charge me another $1000 to install it. I am beyond being aggravated with these incompetent rip-off artists. I am contacting an attorney.
