SOURCE: Carrier air handler tonnage?

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.

SOURCE: could I use wire size 14 for 1 1/2 ton air window

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!

SOURCE: Carrier Durakool 1.5 ton A.C. Moter out of order

If you bought the unit new and it's only 3 months old, the motor should be under warranty and whoever installed the unit should replace the motor for free and Carrier should pay him for the warranty work.

Hi there I have a model number for my carrier a/c unit. I need to find out the tonnage. 38ykc042300 Please any help I will be very greatful.


This is a 3 and 1/2 ton unit.
The 042 in the model number is the tonnage of your carrier unit.
AC tonnage is based on 12,000 btu per ton.
12,000.....1 ton
18,000.....1 and 1/2 ton
24,000.....2 ton
30,000.....2 and 1/2 ton
36,000.....3 ton
42,000.....3 and 1/2 ton
48,000.....4 ton
60,000.....5 ton.
There is no 4 and 1/2 ton unit.
