I Have a Broken Trane Outside AC, Please Help Fix Cheap?

Question by Chris W: I have a broken Trane Outside AC, please help fix cheap?
For the last couple weeks it has been hot. My outside AC broke. I have had a few quotes, ranging from $ 2500 up to $ 4000. I think this is outrageous, however I understand equipment and time can be expensive for some. My goal is to replace this as inexpensive and effectively as possible. I am told I have a “dual coil unit”, which I am led to believe my indoor hardware and outdoor fan/box hardware needs to be ripped and replaced. I am led to believe my outside fan box is the broken part. Why not just replace that?

I would like to know if possible

1) Is Trane, the brand unit I have, universally interchangeable with non-Trane hardware
2) Can I just replace the outdoor Fan/box (I call it that, you know the square grey unit with fan which is installed outside for AC).

I would love to be able to acquire just that part, if interchangeable, used/new, and get the AC running as cheaply as possible. It is over 10 years old made in 1993. The model # is TTR060C100A0. Options? :-) TY!!

What was the diagnosis for the dead unit? If it was a dead compressor, your HVAC contractor is doing the best thing for you. You will be getting a new unit that is more energy efficient than the old unit, and will come with a 5-year warranty. Replacing the compressor or whole outdoor unit with an incompatible unit will negate the warranty, and it will fail in the next two seasons. At that time, you will need to do what you are going to do now; replace the system with a new unit. Don’t go for the cheapest solution; it will come back on you down the road.

You are replacing everything, so call two other vendors and get quotes for 16 SEER systems. Bryant, Trane, Carrier, Lennox are all good, each has its own issues. A cheap unit will cost more to operate, the more expensive higher SEER models will cost less to operate and keep your home comfortable.

Units are expensive now, as copper prices have increased significantly, and the new system will be using a different refrigerant that operates at twice the pressure of your current system. These pressures require thicker copper tubing. The vendor has no control over this; it is mandated by law.

Look at your new system as an investment in cooling your home for the next 15 years, rather than a huge expense this year. The new unit will then cost you between 200-350 per year. Sign up for annual maintenance, or have the installer tell you how to maintain the unit yourself.
