"Simply Awesome!"

5.0 rating
Very Satisfied

This is by far the best furnace that I have ever had. I use a Bear Media MERV 13 filter in the unit and I use a 1″ filter on the return air. This unit heats my home perfectly and the air quality with the two filters I use is outstanding. I purchase the Bear Media MERV 13 filters from Amazon for $56 for a 2 filter pack, and I puchase the roll of 1″ filter from Grainger for $120 (which will last me at least 3 years per roll). I cut my return filters from the roll and replace them once a month.

I have a York Affinity two stage gas furnace and central air conditioner that was installed in 2006. To date, it has been totally problem free. I have both units serviced once a year. Most of the bad mouthing of York products seems to come from ignorant home owners who don’t realize these new high efficiency furnaces need regular maintenance and no brand will be as reliable and maintenance free as models built 30 years ago. If you want high efficiency, you will pay for it, both in new cost of aquisition as well as maintenance and a shorter service life. Such is progress.

York Affinity Furnace – 97.5% efficient! Awesome. It is so quiet and even. I talked to a friend who has been a lead technician in the industry for decades, and he recommended York. Said it was in the top brand category, and uses a heat exchanger that is much more durable over time than some other brands. I’ve had friends with bad contractor experiences, but my contractor was awesome. Find a good contractor who sizes the equipment right, and your York will probably work just as well! Good luck!

I have installed and repaired all brands. They all have issues. My new York yp9c100 is a 98%er. also installed complete a/c unit. Two years gone but not one problem. We sometimes blame the equipment, but in fact, some contractors have not a clue on proper installation practices. In addition, to troubleshoot a poor installation is hard. My advice, (30 years as a contractor-retired) is do not go with lowest price. You have to live with this system for many years. Ask other people about your so-called expert contractor. Not the ones he gives you. If no one in your area knows him, there�s a reason for that.
