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.

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.

"Great furnace"

5.0 rating
Very Satisfied

The York yp9c furnace is as advertised. Very quiet, very efficient. Anyone would be absolutely happy with the Affinity system. As an added bonus, the Liberties Plus Dealer gives a 10-year labor plan for free last year. I understand the same promotion is going on in this area in 2014.

"Dual Fuel Gas Furnace-Heat Pump"

1.0 rating
Very Unsatisfied

Apparently York doesn’t care who sells their equipment until you have tons of complaints about an installer. I was a victim of a terribly poor installer. The technicians installed my furnace and heat pump three times before it came close to a correct installation. It’s my fault for taking low bid. Just remember that the next time you’re in an elevator in a building. It was low bid! We started off at $6400. Now that I have had the system for almost three years I have out spent the original savings. Originally installed without a txv valve. Cost: $330 to find this out. At the start of the second cooling season No Cooling. Cost: $675 to repair a small copper bleed line left laying on a larger copper line inside the heat pump apparently at the manufacturing process. $325 1st visit to recharge it (couldn’t find a leak), $350 on the 2nd visit (3 weeks later) to recharge and repair the leak(they wanted $500 until I complained that it should have been found the first time). Christmas eve 2013 it quit heating with outside temp at 15 degrees. $160 for the first visit to get it operational. Needed a condensation chamber on the front of the furnace that was leaking on the burners and some incorrect wiring as originally installed. $142 for the second visit to replace the cracked condensation chamber and the igniter. Parts under warranty but not the labor. That’s a smidge over $1300 that I have spent on this junk so far if you’re keeping track. If you still want to buy a York then I highly recommend a thorough and complete check of the hvac installer and put back a couple thousand to handle repairs that you’re sure to need.. I will never purchase another York product. They didn�t respond to any of my inquiries on their website either.

"Tremendously dissatisfied!"

Very Unsatisfied

We purchased a York Affinity modulating furnace, model yp9c MP,in 2009. We have had three frustrating winters with it. Have already replaced the mother board, inducer motor and parts for gas jets. Have also paid for numerous service calls. The installer never returned our phone calls the first winter so we’ve been using a different furnace repair company. We’ve tried to email York several times, but the email pops back to us saying the address failed. I would never buy a York furnace again. What a piece of junk.

"Excellent Product, But Installer is Key!"

5.0 rating
Very Satisfied

We built a new home with a York system and used it with only 2 service calls over 16 years. After selling that house and building a new 4750 sq.ft. custom home, we went with a York Affinity Dual Fuel (heat pump with propane furnace) System. We have been in this home for over 7 years and are very satisfied with our York system. We have never had any trouble with it and our York dealer/installer is top-notch. The same technician installed in both homes and is a career heating and cooling technician. He is in his early 60’s and only services the systems he installs, no others. What’s that tell you. I say this because, I think the experience, knowledge, and reputation of the installer is of utmost importance. This has proven true with my 2 York systems over the last 23+ years. I would purchase the same Affinity series heat pump and propane furnace again. We love the extra warmth of the propane when the heat pump switches over. Our temperatures range from 100+ in the summer to below zero in the winter and the system always handles everything very well. Only using between 250 and 300 gallons of propane per year which includes the kitchen use. The electric side of things tops out at about $300/month in summer ac months. Less other times of the year. Very good for a 4750 sq.ft. house with 2 full kitchens and two electric 50 gallon hot water heaters. I hope this information is helpful.


"Worst furnace"

Very Unsatisfied

This furnace was installed in 2008. Every heating season we have had no heat 2-4 times. We won’t go away in fear the pipes will freeze. Dealer always has an excuse. What a piece of crap. Never buy a York.

Other Affinity Reviews

Generally, the Affinity series is regarded as a high quality product across the web. Hvac-for-beginners.com gives the product line its highest rating for efficiency, comfort, and solid warranty. Gasfuranceguide.com also notes the product’s attractive design, quiet operation, and efficiency.

A consumer thread on hvac-talk.com carries more mixed reviews of the product. A handful of people express frustration with their Affinity furnaces. Multiple malfunctions, including odd noises and loud vibrations were among the complaints. Poor customer service with York service contractors also added to the list of issues.

Others on the thread report no problems with Affinity line and site poor contractors as the potential source of system issues.
