Which ones are the best choices of A/Cs and furnaces with the price and warranty that they offer. Thank you for your advices!!

I like Carrier over Rheem or Lennox.

I do question the 100,000 BTUs or even 90,000 BTUs though. Very large house or very cold climate maybe?? Note: That figure is INPUT.

Sometimes the estimators get lazy and put in the same BTUs that were there without considering you went UP in efficiency.

I have serviced many replacement furnaces that were overheating as a result of this. If you had a 100k BTU furnace there before likely this one is too big at 96.6% efficient when the old one could have anywhere from 65% to 80% efficient.

On some new ones that were two stage, heated on two different levels, I have had to lock then in to the low. Or on a few remove a burner because they replaced the unit with the same BTU *input* but the newer ones had a higher BTU *output* due to higher efficiency.

I would almost bet you need a smaller furnace because the ductwork is not designed for one that big at that efficiency. It won’t be able to remove the heat that fast.

Overheating lowers efficiency, more heat goes up the stack, can crack heat exchangers, and generally causes service problems like short cycling on and off.

And it is very hard to address once the unit is there. More is not always better. The heat produced has to match the ductwork’s ability to move it out.

Good Luck

Ps. You usually will find the BTU input for the old furnace marked on the model number plate.
