1.From the info you provided, this appears to be a reasonable price

2.This is a 3.5 ton XR13 heat pump,R-22 refrigerant. Trane sometimes make changes/updates within a model and designate this change with a letter suffix. Not a concern.

3.I suggest a load calculation to verify size required. This is the professional method to size new HVAC equipment.
If you do go up in size, you should verfify with dealer that ductwork system can handle extra CFMs, Plus you need to verify size of your furnace blower. You can not have a 3.5 ton HP or AC condenser with a 3 ton rated blower. Won't work. Now is a good time to address any airflow issues in your home that might contribute to hot/cold spots.

4.You want a Trane coil that is properly matched to your condenser. I would not accept a 3rd party evap coil. Ask for the model number.

5.I would ask for a new refrigerant lineset. Inexpensive and cheap insurance. Has to be sized to new condenser according to Trane specifications. I would ask quoting dealer to verify that new stat has dual fuel capability. Honeywell makes dozens of different models.
Post back with name plt data on your furnace.

Thanks, tigerdunes, for all the feedback. In response to your questions:

* My furnace is a GMP100-4.
* Dealer said he had to install this Honeywell thermostat specifically because we'll be doing a dual-fuel install.

I'll ask the dealer for the model on the coil, plus ask him how much more to replace the refrigerant lineset. Thanks again.

I just heard back from the dealer.

* A/C coil is Trane 2CXCB042
* Heat pump is Trane 2TXCB042
* New refrigerant lineset would be $350.

The dealer said he didn't see any point in changing out my lineset. He said the current lines are seamless all the way from the condenser to the coil. Installing a new lineset would require a lot of it to run exposed outside my house. My furnace is in the attic, so he'd have to run the new line down the outside of the house.

Speaking of my furnace being in the attic, will this cut down on the efficiency of a heat pump by too much? The dealer sent me a calculation which shows that my utility bills should drop about $600 a year if I go with this new system. However, he had a comment in there that the system would work most efficiently if the furnace were located inside the house. I just want to make sure that I'm not throwing money at a solution that is doomed from the outset.

Thanks again.

You want the Trane Heat pump coil TXCB042 for both heating and cooling.

I personally would not want a new system without a new lineset. Linesets are sized according to both condenser size as well as distance from condenser to evap coil. You will not achieve your efficiency without the correct size plus there is always the remote possibility of contaminants. $350 for new lineset is on the high side. Ask dealer what size is your existing lineset and what size Trane recommends for your new condenser and distance to evap coil.

Your ductwork should be OK since you have a Goodman 4 ton furnace. Should not be a concern in this area.

I do not like furnace or air handler located in attic but I assume there is a reason why it is there. Most people don't like furnace or air handler inside home due to noise and space limitations.

IMO

The 2TXCB042 and the 2CXCB042 are both coils.
The 2CXCB042 coil is "cooling only" and not for heat pumps.
The 2TWR3042 is the heat pump.
I would ask to see if an "April Air-mod# 2200" filter system could be installed. No more dirty coils or furnace and it cleans the air. Replace the filter media once a year.
*That is a good price.
tigerdunes has given you excellent info, and I haven't anything to add to that.

I got another quote today. This one was $4,300, but it was for the XL14i (both the coil and outside unit) heat pump. This one uses the 401a refrigerant rather than the R22 that is in the XR13.

I saw posts on here indicating that the XL14i wouldn't be any higher SEER than the XR13 if I don't change my furnace to a matched Trane Variable Speed blower.

So, is the XL14i worth the extra $460? I called the dealer with the first bid, and he said the XL14i would be $1500 more from him. But if I'm not going to see any improvement in SEER ...

Thanks again, folks!

More details on bid #2:

Heat pump: 4TWX4042
Coil: 4TXC042

The bid ($4300) includes install, remove existing, replace disconnect and pad, running the thermostat wiring, and the same Honeywell stat as in bid #1.

Again, this seems like a great price. But I'm wondering if I won't get any better effective SEER from this unit than from the XR13 if I don't also buy the variable-speed blower. Wouldn't such a blower add a lot to my bottom line?

You have a great system quoted. Like you, I refuse to chase down people who are so unprofessional as not following up with either a quote or a telephone call.

A 10 yr ext warranty that includes both parts and labor can vary between dealers. Price range should be $500-$600. Warranty is provided through Trane not the dealer and can be transferrable if you later decide to sell home. You already have a great quote but the dealer may have some wiggle room on the extended warranty depending on how busy he is.

The Honeywell IAQ stat is great at controlling humidity.

The only change that I would make in your equipment is going to the XL14i heat pump condenser over the AC condenser that was quoted plus the matching heat pump evap coil. This will give you a dual fuel heating system sometimes referred to as a hybrid.

My opinion.
Good LucK!

pls disregard my previous post-wrong thread...

my mistake

I purchased a heat peump last year and I didnt know that the heat stripes had to be put in as we noticed the unit freezing up i called someone and he came out hooked up the heat stripes and now i have wonderful heat ,but I have no air if you turn it on the fan blows hot air and the ac blows hot to . It did work last year so i need to know what to do the man wont came back out so i have no idea what i need to do
