Currently have 3.5 and 2 ton Carrier units. Both are 11 years old. 3.5
ton is shot. 2 ton is close. Coils look ok.
Plan on staying in the house for at least 5-7 more years.
1) Trane or Carrier........... leaning toward Trane
2) It was recommended that I replace a Carrier coils that are 11 years old
to match the new outside Trane units (how long do the A/C coils typically
last) and the coil lifetime is not that much longer than the outside units
3) Is this a good price for a Trane 12 Seer XR12
4 Ton Unit
4 Ton Replacement Coil (high efficiency)
2 Ton Unit
2.5 Ton Replacement Coil (high efficiency)
$5,900 installed if buy same time or $3,500 and $3,000 for 3.5 and 2
4) Trane offers a 5 or 10 year extended warranty that can cover parts or
labor or both parts and labor transferable. Is this advisable?
Wrong questions. The first question is how to find a good tech. Then
let them help you with your many options. Hopefully after inspecting on
site and maybe doing some calculations to verify the size needed, they may
make several different suggestions, some you did not think of. They can
give you much better recommendations than we can from here. Get more than
one bid and don't assume the lowest bid is the best.
Choice of make and model is the last part of the process. Let your tech
help you with that choice. In the end, the difference between a good tech
and a poor one is far greater than the difference between a good brand and a
bad one. Of course a good tech will not sell you a poor make.
How do you find a "good" tech? What should you be looking for when
evaluating a company?
We are in the market for a new heat pump, and have had 6 different
companies provide quotes. Its almost overwhelming trying to determine
who is providing the "right" information. As you can probably surmise,
the quotes all have different recommendations (ie, one thinks that the
return needs to be moved inside the house, another thinks everything is
fine and just replace the existing unit, another thinks we need a bigger
I dont sell Carrier, or Trane..yet...(still thinking about picking them up
as a lower end line) however...
1- Who has done the correct manual T, (not J, this is a heat pump,
If no one...they dont get the work.
2-Who has done the Manual D duct calculation? If no one...they dont get the
Manual T will tell you the EXACT size unit you need. Guesses are NOT what
you want when you are dealing with hte most abused, and expensive applicance
in your home. Manual T is a heat loss, heat gain calculation that will allow
the contractor to properly size your unit, based upon YOUR home, not HIS
If they dont do it....screw them...seriously...boot them to the curb.
Too large a unit is worse than a too small a unit.
Manual D can not be done until the units size is calculated with a manual T,
or J, or N...however, you are getting a heat pump, so that is a "T". Manual
D is a duct sizing calculation that insures that the unit that is being
installed has the proper static pressure to operate, AND insures that you
are getting enough CFM per ROOM to peroperly cool and heat it. Getting a new
unit, without this being done, even on existing equipment, is wasting your
money and time.
No one wants to do it...boot them out.
After you find someone that will do that, you need to look, and verify the
Workers Comp Certificate
Once you have done that, insure that you are NOT getting a Janitrol, or
Goodman, or any brand they rebadge...if you are looking for a lifetime
warranty on the compressor, other brands offer this. Forget the name on the
unit...go for the contractor that will install it correctly.
Given that information, also keep in mind, that while Carrier is a decent
unit installed correctly, most all their units are R410A, or Puron.
Personally, as an owner of an HVAC company, I do not advocate it...not yet.
Too many replacements for R22 starting to hit the market and last time
Carrier came out with a magic safe refrigerant, (R500) it failed after a few
years. Now R500 is more expensive than R12.
York, the company that I sell, offers Puron units, but they are looking into
other refrigerants, and the industry may just go another route, so you will
want to consider R22, a refrigerant that is proven, cheap, and will be
around long after this unit that you are about to buy is toast.
Go with the highest SEER rating you can afford. The MINIMUM standard
starting in less than 2 years will be 13. Currently, it is 10. IF you want
to be ahead of the game, look at nothing but 14SEER and higher units. They
cost more, but normally have a longer and better warranty than the cheap
stuff...and you DO get what you pay for.
The brand name does not matter as much as the name of the installer. You
need someone that knows what they are doing. BUT! You need to get at least 3
different quotes (QUOTES!! Not estimates!) and go from there.
Ask your friends and neighbors who they would use.
If you are changing the outside (condensing) unit, you would be wise to
change the indoor (whether a coil or entire air handler). If this guy is
putting a 12 SEER unit outside and NOT changing the evaporator coil, I doubt
very seriously that you would get 12 SEER out of it.
Prices vary so i will not comment on the ones you listed. As I said above,
get at least 2 other quotes.....
At 11 years, depending on where you live, both are shot..
I dont like the fact that if either breaks out of warranty electrical wise,
you pay through the nose for parts.
BTW, the name on the unit means nothing, its the install that makes the
Umm...you NEVER install a new outdoor condensor on evap coils that old. In
other words, if someone told you that you can keep the indoor coils and
replace the outdoor units only...kick that hack to the curb. It is a waste
of your money to do this and anyone that tells you otherwise is wrong.
Nope. Too low...seriously.
(and I say this, since I have been considering a Trane dealership as my
cheaper brand, that is more well known here in my area)
Where is your new matched lineset? For BOTH units. What is the SEER rating?
High Efficiency means nothing...anyone can put that on a unit and someone
will buy it.
Today, High Efficiency means 14 SEER or HIGHER. 10 SEER units used to be
called HE units, then it was 12 SEER, and now, with the 13 SEER Federal
Ruling on the way, 13 SEER will be the cheap crap, and 16 SEER will be high
Sounds like some salesman either saw you coming, or you are leaving
If you can get it for under $400...cause you WILL need it.
I kinda like my units 10 year warranty, that includes a lifetime warranty on
the compressor....the labor warrantys included in the price....but....each
company is different.
Thanks for the info guys. Appreciate the feedback. Model numbers for
the equiment is below
Some additional info from my experience thus far.
The repair tech that came out to check the systems seemed very
knowledgeable. He advised me that the valves where shot in my 3.5 ton and
very weak in my 2 ton. He put a pound of freon in the 2 ton and advised me
that it was futile to fill the 3.5 ton. Further, he did not charge me for
the $57 flat rate visit or the freon for the 2 ton unit.
The Sales Tech from the same company came out and advised me to replace both
the outside unit and the coil so there would be a good match. (I was
pushing for just the outside unit).
Said that Compressor/Condenser and Coils usually last up to 11 years. Said
I could go from a 3.5 ton to a 4 ton as the housing in my existing Carrier
was capable of a 4 ton. The tech went in my attic where the units are and
computed the amount of cu ft going out of the 3.5 ton unit to determine if
there was enough to hadle the extra 1/2 ton. After computing it, he advised
me that is was right at 3.5 tons and that by going up to 4 tons, there
would be a little loss in efficiency as the outbound capacity was a little
less than it should be for 4 tons. I still chose to go with the 4 ton as
the price wasn't much different.
He computed a SEER of 12.25 for each of the units based on using Tranes high
The model numbers for the outside units are the XR12 for the 4 ton and 2
2 ton: 2TTR2024A1000A
4 ton: 2TTR2048A1000A
The model numbers for the coils are:
2.5 ton: TXC031S3HPC
4 ton : TXC054S3HPC
Price includes Condenser install and Coil install for both units. Again,
the total was $5,925.
