I am about to start an 3 ton central AC in my 1500sq ft Ranch, I have
all the wiring run and poured the pad, I am going to get a Payne unit
question I have is the HVAC tech who is going to braze the lines and
set up the system after I am done, gave me a choice between a
PH15NB036ooG which is a 15 SEER Heat pump & cooling or a PA16NA036oog
which is a 16SEER cooling only, the heat pump model is actually $135
less money, and the air handler would be a PF4MNA037. in the long run
are there any more expensive parts in the Heap pump unit, is this a
factor to be thinking about. which would be the wiser choice,
What did the Manual J heat load/loss calculations come out for sizing the
Before you get too far, you need to *READ* the warranty sheets.... any
equipment bought from the internet has *NO WARRANTY*.
Also be aware that no legitimate company will install any equipment that was
not purchased through their company due to liability and warranty issues.
That being said.... your a cheap bastage... if you don't take anything else
from this forum, remember this;
"The bitter taste of a poor quality installation will linger far longer than
the initial sweetness of a low price."
Sounds like the installer used a "rule of thumb" to size the system....
thats nothing but a guess.... and you gonna base this decission on a
*IF* the installer did the calculations, you should have gotten a print-out
of the results.... OTOH, if you went with him because he was the lowest
price, all bets are off..... sorry about your luck.
That is what I had in mind also, I ask my installer what his opinion
was,he would go with the heat pump because it was cheaper, I think I am
going with the cooling only
actually my installer does work for the company I am a manager of. and I
use him for our business's heating & cooling. I had 2 other estimates
for my home last fall one guy suggested a 2 1/2 ton and the other
offered either the 2 1/2 or 3 ton
So nobody has actually done the math to correctly size the system for your
home..... Its not like going to Walmart and buying a toaster that plugs into
the wall. *IF* the installer is doing his job right, he should be designing
the system specifically for your homes needs. You are about to make a
decission that your going to have to live with for the next 15 - 20
years..... Hire a professional, not the lowest bidder or somebody who "does
it on the side".
As a consumer if I am having an installer do work on my HVAC needs I
want him do the basics first. Manual J calculation to get at the system
requirement. He has to look at duct system too. Installing either
under/over sized system is economically bad thing and also it'll
impact your comfort level. Payne is low end Carrier costing less.
There is a reason it costs less. Like Armstrong is made by Lennox.
I am familiar with Carrier and always stick with Carrier and good
dependable(knowledge, training and experience) tech I have known for
years. Do the right thing and enjoy the result for many years to come.
