Help I Think
hvac is not my trade so bear with me please. i just built a house and had to use a new hvac guy. he priced me a 80% bryant furnace with 55000 btu. this home is 1750 sq.ft with 2 - 15' cathedrall ceilings. is this a big enough furnace there are 3- 4x12 returns in the bed rooms (1 in each rm)and 1 16"x16" in the living rm. the living rm and the master bed have the vaulted ceilings. hopefully this is enough info. anyway i was wondering if this is enough of a furnace for the home. i have 2x6 walls with the blown in blanket and roughly an r-40 in the ceiling ( blown-in) any info would help thanks in advance

Re: Help I Think
Hi benchmark2323
If you are a ACCA member its pretty easy to get this information. To do the calculation it will ask you windows, construction ,climate , etc. AirPro is dead on accurate, if he did not do this he needs to be fired. You may be able to go online to a ACCA site and download the manual J. Many things have changed since I got mine. One of the other guys may be able to tell you where to get it also. Good luck Rusty |

That is what I use to get the #'s, I then do the duct design and layout using a ductulator. You can buy the manual D add on to do this for you, but I couldn't justify the added cost to replace something I have been doing by hand for years. There are also people that do these for a living, so if you won't be doing it more than once, you can just pay a certified energy rater the $150- $200 to do it for you....Or find an HVAC contractor that is professional enough to to the job right and include it in his bid. Good luck!. |
