Widely used measure of the fuel efficiency of a heating system that accounts for start up, cool down, and other operating losses that occur during real life operation. AFUE is always lower than combustion efficiency. Furnaces sold in the United States must have a minimum AFUE of 7. High ratings indicate more efficient equipment.

I had the same problem, looked everywhere for the mythical E7 code which by the way I have yet to find and thought was lost until I read the manual again.

Its only 4. So you tell them to go ahead and install the 9. Your old one, remember, was rated at 6. BTUhour of input capacity. They look in their product catalog and find that the high efficiency model comes in a 4. BTUhr model or a 6.

BTUhr model, and they dont want you to freeze, so they install the 6. BTUhr model. Looking at the wrong capacity. Hmmm. See a problem here Many HVAC sales people and techs think in terms of input capacity for furnaces. To them, the 6. 9 K model is a little bigger than the old 6. C+especially+if+the+ducts+run+through.jpg' alt='Del Air Air Conditioning Manual Trane' title='Del Air Air Conditioning Manual Trane' />K model theyre replacing, but not too much bigger. Actually, its worse than that. The relevant capacity of the furnace isnt the rate of BTU input. Its how quickly those BTUs go into your home the output capacity. Lets look at what happened to those numbers when you replaced the old furnace. You started with 6. BTUhr at 8. 0 efficiency, so your old furnace supplied 6. BTUhr. The new furnace has an output capacity of 6. BTUhr. To summarize the numbers Input    6. BTUhr new furnace    1. Output  4. 8,0. 00 old furnace 6. BTUhr new furnace    3. So, your new furnace is 3.

If you live in an older home with air leakage and insulation problems, you may notice that youre less comfortable. The furnace comes on and blasts you for a few minutes, possibly making you uncomfortably warm in some parts of your home. Then it goes off, and you feel the cold walls and the drafts. What can you do If youre getting a new furnace, ask the HVAC companies you get bids from how theyre planning to size the new system. There are a lot of ways to do it, and many of them are wrong. Some acceptable ways would be to do a Manual J heating and cooling load calculation, use manufacturers sizing software, or monitor the amount of runtime of your current system, especially at design conditions. Probably the least reliable way to do it would be just to look at what size you have now and install that size or larger. To make it worse, just look at input capacity and ignore the effect of installing a new system with higher efficiency. Bigger isnt always better. When it comes to heating and cooling your home, its often worse.
