Thanks, I am confused as to why the model numbers are different and want to make sure I get the best system for my $.

Thank you!

the same...

Yes both are equivalant, Trane has Models and then Model numbers its like buying a car. You can get a Toyota Camry but the the car could be a Camry 3.0L or Camry 4.0L
The heat pump is the same, It is a Trane XL20i but the model number is a 4TWZ0036

Awesome - thanks guys! I feel like I need to go to HVAC school to figure this out! A couple final questions - which will help me make my decision...

I dont have a hybrid today. One vendor is telling me they will have to run new lines and make 9 to 13 holes to fish teh lines in my dry wall for the hybrid system.

The other vendor is stating...

"As far as the hybrid system I will not have to run a new tstat wire. The one you have is fine, I am not sure what the other company is talking about or maybe they do not feel comfortable installing a communicating hybrid system , but you have enough tstat wires."

One vendor (the one that said they need to run new wires) quoted me a 17in furnance and stated...

The 80K BTU 17.5" furnace has an airflow rating in tons of 3.0 which matches the tonnage of the AC condenser. The 80K BTU 21" wide furnace has an airflow rating in tons of 4.0. We feel that it is better to match the airflow capacity of the blower on the furnace with the tonnage of the AC condenser. However, with variable speed and 2-stages it's not as critical for it to match exactly. The price we gave you would cover either the 17.5" or the 21" furnace if you have a preference.


The other vendor quoted a 21" furnance. My comfortermaker that is currently installed is 13 yrs old is a 19" wide.

Final, question...Do I go wiht the 17" or request the 21" for the same price?

Is one referencing new refrigerant lines and the other Tstat wire?

With the 21" wide furnace you get an extra .5EER and .25 SEER so it is slightly more efficient and "can" be setup to properly work with a 3 ton XL20i system. The vendor that quoted this looked up the ratings to find the best Match for you +1 point for them.
All these systems are communicating so they only require a 3 wire thermostat wire which you surely have. The company that says you need new wires I would be VERY leary of because they don't know jack about these communicating systems or will hook it up wrong if they are running/using more than 3 wires. It sounds like the same vendor knows how many wires are need so another +1 for them. I think the choice is obvious, one company does not know what they are doing and one has their ducks in a row and knows there stuff.

[mdelaney16]

Awesome, just so I have this right - there is no need to run new wires?

Correct, the same company quoted me the larger 21" furnance from the beginning and told me I dont need to run new wires...they are $260 more expensive, but I would rather pay and have it done right

I really appreciate your insight. Huge help right now since i dont no HVAC and was getting conflicting info. This is a lot of $ and I want to make sure it is done right. Much appreciated.

[mdelaney16]

Excellent, thank you. You just made up my mind. The company that said no new lines are needed and quoted the 21" furnace from the beginning is $260 higher, but I'd rather pay more and know it is being done right.

I really appreciate it. Very hard for us layman to understand HVAC when you get conflicting quotes, model #s, and details about the installation. This site is awesome to get a professional, unbias opinion and to help set the record straight! Thank you so much - I now feel better about making my investment - which isnt cheap!

Make sure the old refrigerant lines are the correct size and within the design limits for the unit, maximum of 80 feet and maximum of 25 feet vertical lift and 3/8th and 3/4th.

What if anything are you doing about a whole house air filter cabinet?

The performance/eff numbers between those two furnaces are really inconsequential.

Normally, I would say just go with the one with the best numbers.

However, one of the nice things about Trane and AmStd is there components like evap coil and filter cabinets are made to fit the furnace. Makes the system look better visually rather than a junkyard install.

Ask dealer about the size of the evap coil to the furnace?

And I want to go back to the refrigerant lineset. It s important if you plan to reuse existing that it is the correct size that Trane recommends for the XL20i.
Ask dealer if he has verified this.

IMO
