Hello I have Heil A/C unit, and I'm looking to find out the size of the unit, i.e. 1.5 ton, 2.0 ton, 2.5 ton, etc, as I am looking to replace the unit. The info of the unit is below, any help would be appreciated.

look at model no. 24 is 2 ton 36 is 3 42 is 3.5 and 60 is 5 ton

Hi,
You will never tell the difference, but it looks like it is a 2.5 tn unit..

Hello,You have a 3 1/2 ton unit

Hi,
The model you gave is for a 3 ton or 36000 BTU unit...that is what the 36 stands for in the model number...

Hi,
It looks like you have a 60,000 BTU unit or a 5 ton unit...12,000 BTU/ton is how you figure that...
The 60 in the model number indicates the nominal btu's of the unit... the exact output could be a bit more or less depending on the air handler...

ANY # DIVISABLE BY 12. MODEL HAS  12-24-30-36-40-48-54-60 12 1 TON 24 2 TON 30 2 1/2 36  3 TON 36.00 BTU 40 3 1/2 48 4 TON 48.00 BTU 54  4 1/2 60 5 TON   60.000 BTU

thats a 5 ton ac unit

10AJA6001AH

basically 1 ton = 12,000 BTU

so 24 is 2
30 is 2 and a half
etc

No sir,14 gauge,three conductor will carry only up to 15 amps,which is usually wired for lighting circuits.Look on the electrical requirement plate on the unit,usually located under the front panel cover.It will tell you how many amps are drawn when unit is operating.Using a three conductor cable;wire accordingly:#14--15amps----#12--20amps---#10--30amps----#8--50amps.These are the wire sizes and the current(amps)they will carry.Be safe! Gregg

it depends on the distance from main power source # 8 if more than 40 feet look at starting amps then google a wire sizing voltage droop chart

That is a fairly large difference. It is usually ok to have the inside evap. coil and blower up to 1 ton larger than the outside condenser. That will make the unit slightly more efficient as well as less likely to freeze up on low airflow situations. It is not recommended to install a new condenser on an old evap coil. There has been a lot of changes to the design of the coils in the last little while. For example a 10 year old 2 ton coil may only have 3 cubic feet of volume but a new 2 ton coil may have 4 cubit feet of volume.

There are many factors that may have infulenced the decision on what size condenser to install. Many of which can only be done by visiting the home and doing alot of work, checking the duct sizing bioth supply and return, inspecting the insulation and windows of the home etc. etc. Most of the time that never gets done. You can blame the contractor for not doing a complete check, but at the same time you can blame the customer because many contractors that are that good loose the job to a cheaper bid that did not no any of the research. It is a catch 22 for everyone involved.

There is ALOT more to sizing equipment that many people think, sadly that also includes many HVAC contractors. Way too many people use "rule of thumbs" or flat out "guess".

Sorry for the rant but your queston can only be answered by a good well educated HVAC contractor visiting your home. That type of a contractor is getting hard to find these days in such a price competetive world.
