Carrier ductless condensation leak

If you are running it in the cooling function, your drain maybe backed up. Find your drain outside if you can and suck it with a shop vac.

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: My Carrier AC fan will not turn, only blows out warm air.

Breaker has popped either at breaker box or at the safety shut off switch. Fuses are blown or the sending unit has popped.

SOURCE: My carrier air conditioning unit does not cool below 72 degrees

The unit has lost part of it's charge, and will need recharged. For that reason a leak must be found and repaired or it all will reoccur again.
