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: Amana 1 ton Residential AC / Outside unit comes on for a sec

open the service panel to check for control voltage of 24volts when tstat calling, The contactor should be pulled in, if contactor is down,and contacts appear to be clean, and the unit is still not running, it is a bad compressor. to test this unplug the black wire from the compressoror at contactor,w/ power off! Turn on power if fan works normally it's a bad compressor. However if you see a swollen split cap(5 wires to a soup can looking w/ the terminal C,F,and Comp), switch it first and start at square one.
You also need to consider the high pressure switch if its cycling on off on off.

SOURCE: AC will not cool. How much should a service charge cost?

If the upstairs is working and the down stairs is not,You only need to have one unit checked,Don't assume it just needs puron(If it does,You have a leak,which cost more to locate and repair than some other likely causes)This is not something you can do yourself and is illegal if you are not EPA certified.to get a fair price would depend on your geographic location and the best way would be to call around to some local heating and air companies and ask how much a service call is.(That only tells you the price for them to came and see what the problem is,They will not be able to quote a price until they know what must be done to make the repairs.

I hope this has answered all your questions.

What is the tonnage of my carrier AC unit model number 38ckc036340


Most likely a 3 ton judging by the "36" in the number. This is pretty standard in most all cases.

Hi, the tonnage of this unit is a 024, which is a 2 ton. There are 12, btu's per ton of cooling, and this number will always be in the model number of the unit. If it were a 21/2 ton it would say 030, 3 ton is 036 and so on. Please feel free to rate me, and I thank you very much.

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.

Air condition unit of sufficient size??


You currently own a 2.5 ton AC Unit
500 square feet equals a ton of cooling/ you need a 3.5 ton unit.
If your home is well insulated, good windows and doors and pretty good
shade that covers your house, then I can see a 3ton unit cooling your
house.

Thats another 6,000 btus you do not have and that is a best case for a
energy effcient home.

Can I mix brands/tons when installing AC unit to existing coils?


First off - the 'rule of thumb' is 600' per ton of Air Conditioning. In other words your old unit is a 2 ton unit. So - 2 tons x 600' = 1200'. As you can see if you install the 2.5 ton unit - you will be installing a AC that 'could' cool a 1500 sq ft house (2.5 x 600' =1500 sq ft.). Slightly more than what you need; and the 3.5 ton unit is 'way to big,' (3.5 x 600' = 2100 sq ft.).

Note: fyi - many in the AC business will sometimes refer to tonnage in btu's, i.e. 1 ton = 12000 btu - hence a '2 ton unit' can also be referred to as a 24000 btu unit and vice versa.

So... from the above - you can easily see that "2 tons" of Air conditioning is what is required to cool the 'average' home of 1100 sq ft. "roughly speaking."

Note: it is always best to have a professional 'size' your cooling/heating needs.

One of your questions was could you 'mix tonnage?'

The answer is 'usually you don't mix the tonnage of your outside/inside units.' However, professionals sometimes do (mix the tonnage) in certain situations, and installing a 2.5 ton outside unit with an existing 2 ton inside unit is often done, however, there are some 'tech issues' here and - I would "again" recommend that you call a Service Tech to help you with the sizing/mixing of your cooling/heating needs.

hope this has helped
