This is not the appropriate forum for free schooling. You need to have a technician teach you in person in a hands on manner.

The outside fan in my carrier unit will not stop running when temp inside has been reached?


There can be multiple problems with your situation, one being a stuck condenser fan motor contactor/relay, a shorted motor, bad control board, etc. If you could at least check the contactor that controls the CFM and see if it is pulled in that could help narrow down the search for the answer.

What is the age of the following Carrier RTU - Model # YCDO6OC460BF & Serial # R28105287D I have been told 1982, 2000 & 2007. The unit does not look that old, so do not believe it was a 1982,...


YCD060 is a Trane unit number not a carrier. Trane has a large guide for looking up approximate age of equipment. There is no date coded in the serial number, Trane does include a mfg date on most of the labels on later equipment, look for it on top or bottom corner of label if you can still read it otherwise I have the cuide at the office and will look it up this week. FYI our company is a TCS Trane dealer.

I had a power surge on my 15 year old HVAC residential Trane Unit. I can either have my insurance repair it or I can pay the difference to replace. I do have coverage to pay for Alabama state building...


13 seer minimum for new installs. I have seen ratings as high as 18 or more on
some units (410A systems)
I recently replaced my system with a 13 seer R22 system, since they are
more easily serviced and I am very familiar with them. Given the average lifespan of
a system before major service is around 10 years depending on model.
I have worked on Trane, Carrier, Intertherm and Goodman units and prefer the Goodman
units, as they seem to be much quieter running and are built in America.

    If i am in the process of buying a generator to run 2 carrier RV rooftop ac units how big should the generator be?


    You need to find out the maxamps of the rooftops which is located on each unit, then you will need to find out if these are 1phase, 2phase or 3phase units.
    That information is also located on the unit and usually is marked 1P or 2P or 3P. If its 3Phase you
    would need to talk to a electrical contractor or the
    manufactuer of the generator you wish to purchace.

    More in for is needed on the phase of the unit and amps that it draws

    Goodman is are decent (builders grade) equipment. Not as good as Trane or Carrier but if it's installed correctly it should be fine. Goodman is mainly a residential brand but they do make some light commercial equipment which again is decent as long as it is put in correctly.

    My rooftop Trane A/C unit shows high humidity on the thermostat, will not cool the house during the day but cools fine at night. What could the problem be? Also, how can I lower the humidity in the house?


    High humidity causes Icing of the cooling coils. Avoid constant running of the a/c. Meaning let the AC pull the house dow 2 - 3 degrees at a time.. The unit shutting off will allow the ice to melt. Make sure the drain is clear by going outside and chkg for drainage. Once the house is reasonably dehumidified the ac can be set and left on its own.

    No heating, cooling or fan.


    I'm confused. You have a Trane, but are asking about the Goodman warranty. I missed something there I'm sure, sorry.

    "IF" Trane has a recall or warranty issue, then any qualified technician should be able to help you with that. The parts would be provided by trane in such an event, but unless the unit is less than 1 year old, chances are you will have to pay for the labor.

    Being an electricain help if you want us to assist you in troubleshooting.

    This link takes you to the TRANE contact page. They can answer any warranty/recall questions you have.
