York Latitude or Affinity Series & Reliability
So, we've had three contractors come by & all three have proposed York equipment.
Two of them have proposed York Latitude Series, the third proposed the higher efficiency York Affinity Series.
Even though the Affinity Series has higher efficiency, one of the contractors that proposed the Latitude Series suggested that the higher efficiency furnaces such as the Affinity Series have reliability problems, especially with circuit boards.
I'd like to know what the experience of the folks on this site have had as far as reliability is concerned with the York Affinity Series compared to the Latitude Series.
Let's talk about a few things -
I live in NJ too. The first floor of my 1948 house is 1550 square feet. I have a 45,000 BTU gas furnace happily heating it. Houses are all different - you need accurate heat load calculations done to determine what You need. I am not telling you what you need, but I'm thinking that the smart money would be betting Against a 100,000+ BTU furnace requirement. <g>
Next - if you are buying an air conditining system anyway - do yourself a huge favor and pay the few percentage points more and get a nice heat pump system installed along with your new furnace - instead of just the straight AC. Running the HP during at least half our winters will save you about 30-40% on your heating cost during that time. If your contractors wrinkle their nose or frown before telling you not to buy a heat pump - they are not on your side in this fight. I can back that up with some real numbers if you think I might be a crack-pot. <g>
Bonnet Capacity = Input
Furnaces used to be rated based on stack loss = so much gas burned = so many BTU's. Subtract what went up the stack from that and the remainder was assumed to be provided to the consumer.
Now furnaces are rated based on heat output to the conditioned space and the remainder is assumed to be stack and other losses. Which is a much fairer description of what the consumer will actually receive.
Do yourself two favors - get several accurate heat load calculations done on your house as it exists today. From isolated sources. If they don't agree - find out why. Have them do both heating and cooling. And buy a heat pump to go along with your furnace. You checkbook will thank you for decades to come.
