York Affinity 9V Furnaces

York Affinity 9V Furnace Overview

Designed as a quiet and efficient furnace, the York Affinity 9V furnace had an AFUE rating of more than 92 percent. The furnace earned an Energy Star rating and Good Housekeeping Seal and, according to the manufacturer, had the potential to save the consumer up to 35 percent in utility costs. The 9V furnace had an insulated cabinet and could be configured as a downflow or horizontal flow unit. The unit was available in six models.

The Affinity 9V featured an ECM motor and ClimaTraK technology. The ECM motor was designed to ensure long operating cycles that maximized air circulation. As a result, air pockets did not form and the temperature was consistent throughout the home from floor to ceiling. The fan changed speeds gradually for better efficiency and sound levels during operation. ClimaTraK provided the ability to set the furnace to operate on a cycle that maximized temperature and humidity comfort no matter the climate. The Affinity 9V furnace was part of the York Affinity series.

"Never buy York furnace!"

5.0 rating
Very Satisfied

Waste of Money. Service call every winter. Never able to bring temperature to above 21 Celsius.

"Best Gas Furnace 2017"

5.0 rating
Very Satisfied

Ultra Efficient, Quiet, Comfortable – Those are the words that best describe York’s 2-stage Variable Speed gas furnace. Featuring an ecm motor, efficient continuous fan use is available to improve indoor air quality with optional humidifiers and air cleaners. Changes in fan speed to high and low heating are smooth, and the low stage heating provides a better match to actual building heat loss on milder days. This technology combines to keep space temperatures more constant, improving comfort even more. Combined with one of York’s high efficiency cooling options, this furnace is a top choice for consumers looking for a step up in comfort.

"Poor warranty will only last about 9 years"

1.0 rating
Very Unsatisfied

My guess is they have the motherboard scheduled to die around the ten- year mark. Mine made it to only 8 years then the motherboard killed itself. Built in obsolescence is my guess, not moving parts so it’s just a scheduled expense to get the repair guy back or its simply a garbage motherboard. Either way, it’s about a grand to keep it running. Since there are no moving parts to wear out it makes no sense whatsoever. Do not buy York….garbage.


"Great install, great equipment"

5.0 rating
Very Satisfied

AirWise Ingleside,Illinois, installed my York 2 stage furnace after my American Standard failed after 15 years. Very disappointed with the quality and longevity of that furnace. Installation was done in under 2 hours and the furnace is gently and quietly warming the house.

"Uber efficient York Affinity"

5.0 rating
Very Satisfied

I had the HVAC system replaced in my 4000 square foot home with a new York Affinity Series system based on the recommendation of the contractor and independent reviews I conducted. The promise of high efficiency with this system was more than realized! The A/C keeps the house uniformly cool and uses less electricity than the old system and less than advertised and I am very pleased. It is in the heating component that this system really stands out! The installer said, “Your propane guy is really going to hate this” and he was so right! This furnace sips propane like a 50 year old Scotch! The propane usage has gone down by at least 2/3 and I am now easily getting two seasons heating from a single fill of the 500 gallon tank! Affinity heats the whole house for the entire winter for about $300.

Other Affinity 9V Reviews

Considered to be a high-end product, the Affinity 9V is reportedly both efficient and reliable. Dealers emphasize the importance of installing two-stage thermostat to get the most out of the unit's capabilities.

In the event of a problem, the 9V shows diagnostic fault codes. Using the code, one homeowner posting on justanswer.com seeks help determining why his furnace won't start but his vent fan tries to operate. Contractors on the forum suggest cleaning the hose to the induced draft meter and trying the jumper switch. Finally, the homeowner shares the installing technician's solution. It seems the vent's vacuum sensor was defective. The tech says this has been an ongoing problem for the furnace, and that the "glue" on these sensors did not hold.

Affinity 9V Warranty

The Affinity 9V Furnace comes with a lifetime limited warranty on the heat exchanger and a 5-year limited warranty on all other parts.
