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.

"York modulating furnace."

5.0 rating
Very Satisfied

Replaced a 10-year-old Carrier 2 stage with ECM motor. This furnace is much quieter. The master bedroom is directly above the furnace and I hardly know when it’s on. It’s very efficient. I did not need a special modulating thermostat to run this furnace. All the other furnaces I checked needed one, at a very high additional cost. I could not be more pleased.

"Expensive piece of junk"

1.0 rating
Very Unsatisfied

Furnace has been in service less than 2 years. This is already the second service call. This time it is going to cost us over $600.00 to fix this piece of junk. Switched from oil to natural gas to save money. Should have stayed with our old, reliable oil furnace. Do not buy this lemon!

"After 75 years, worst furnace ever"

1.0 rating
Very Unsatisfied

In the six years that the furnace has been installed, I have had the contractors replace switches, mother board, gas valve, igniter, etc. Charges have reached over a thousand dollars. In my previous new home with a Trane furnace, I never had a service call. I am very disatisfied with this new York furnace/AC.

"York furnace dealer"

5.0 rating
Very Satisfied

I’ve been a York dealer for 35 years and I install equipment the way it should be installed. I have very few problems with the equipment I install! It’s too bad there are so many fly by night installers out there.

"Utter nightmare for 7 years!"

1.0 rating
Very Unsatisfied

We replaced the 50-year-old furnace because parts became unavailable. Even though it broke infrequently (every 7 years or so), we couldn’t risk it. So, the York. Reviews looked good. They sold us on the air cleaning unit. From installation on, it was a nightmare. Didn’t work the first month. Didn’t work after that. Techs came out every week, sometimes every day. Water was pouring out of pipes into the crawlspace. Mold developed in the crawlspace (had to get encapsulation and mold removal, $10,000). Back to the furnace itself – they moved water drainage to a bizarre system where tubes run up my wall, around the ceiling, into the washing tub! And still, that didn’t work either. 1. Had the board replaced, and fought York to honor that warranty. Finally they did, but total labor costs to us the first year were in the thousands. 2. Had other parts, one after another, replaced. 3. The water drainage flooded itself and rusted out everything again and again. Water leaked out of the thing all over the floor. 4. It doesn’t work better than it did. It’s just that we pay and pay and pay, like idiots, only because we can’t find another furnace that anyone really likes. All the furnaces look like the same thing could happen, from reading reviews. Now, we have to get a new one. Furnaces are only supposed to last a few years, right? Certainly not 10 years or 15 years. It can be fixed this time – but at a cost half that of a new furnace. Why don’t we all just buy a new furnace every few months? Is that what they are aiming for?
