"Worst of the worst out there"

1.0 rating
Very Unsatisfied

Can’t stop a Trane is a lie! More like, can’t stop a Trane from constantly breaking! Every year I have to take apart the furnace when the house freezes just to clean a flame sensor! It’s loud, it breaks and this is the worst furnace I have ever witnessed. Total garbage. Stay away!

Very Unsatisfied

3 months after the warranty expired, heat exchangers broke. Enbridge replaced my last 40-year-old furnace because their leaky water tank leaked underneath it and broke it, and never said a word. Last furnace never left me stranded in the cold each year like this Trane, that needs the flame sensor to be removed and cleaned with very fine sand paper or steel wool. (What do seniors do I wonder, call a repair man every year for this service?) Trane and their partner are scam artists as far as I am concerned. This unit is horrific.

"Trane furnace review from satisfied customer"

5.0 rating
Very Satisfied

This furnace was in my house when I bought it, which was 6 years ago. The previous owner had purchased the furnace four years earlier. It heats up the house nicely. I do live in the South, so we don’t have extremely cold winters. It has been very reliable. I have only had one problem with it and it was very inexpensive to repair. I believe this was an electrical issue which interfered with the furnace being able to cycle on and off properly. This repair was done 3 years ago and we have had no further issues with the furnace. I especially like the efficiency of this furnace. My gas bill is reasonable even in the middle of winter. I would recommend this product to a friend. If I need to replace my furnace at some point in the future, I will probably look for something similar from the same company because this furnace has been so reliable.

"We use it as an alarm clock!"

Somewhat Unsatisfied

This furnace replaced a 12-year-old Lennox two-stage that had a mind of its own and left the HVAC dealers scratching their heads. I thought the Lennox was loud, but this thing sounds like a jet trying to take off. I’m on a concrete slab with the utility room centrally located. That’s part of the problem. It’s not isolated. The draft motor whirs away and when the inshot burners light – it’s blast off! I can’t complain about heat, though; it warms the house better than the old Lennox. I’m going to add some sound-deadening material to the utility room to try and quiet it down.

I’ve owned a Trane XR80 for five years now. Not one problem out of this furnace!

Other XR80 Reviews

On users recommend Trane, Lennox, and Carrier as good brands but pricey compared to the less expensive Rheem and Armstrong. Consumers on both and describe problems with the XR80 control board resulting in no heat. Contractors commented that this is not an unusual problem.

Question and Answer


I see a red light flashing on my Trane furnace. What does that mean?


Your Trane furnace has a flashing light to tell you if your unit is functioning properly or not. A steady flash is normal and means the unit is working properly. A series of flashes and pauses is a code for something wrong with your furnace. A breakdown of the flashing codes and their meanings should be located on the inner front panel of your furnace. An error code is usually a problem which requires a qualified heat tech to repair.


What is the cost to replace a Trane furnace transformer?


On 2016-07-29 Gary wrote:

If you have the part number, many Trane furnace transformers can be purchased from online HVAC suppliers. The cost of a transformer should be around $20. You could also contact a licensed heating tech who can make sure you get the correct transformer and install it for you.


My Trane XR80 furnace is blowing cool air


On 2015-11-18 Eric wrote:

On page 8 of the owner’s manual there is a troubleshooting chart on common issues with the furnace. On the chart it states:

No Heat — Vent motor is running

Possible cause – Restricted or plugged furnace condensate drain

This is the solution they provide

    1. Remove drain clamps to condensate trap and drain pan outlet
    2. Flush or clean drain blockage
    3. Reinstall clamps

If you’re still having issues with the furnace or this is not the trouble you’re having, calling a licensed contractor would be a wise choice.

This furnace should be flashing an LED error code which can help you diagnose the problem. A few possible causes of a furnace blowing cold air are a dirty filter, a problem with the capacitor, a plugged air intake or a problem with the blower motor. Having a licensed tech troubleshoot and fix your furnace might be a good idea and help prevent further damage.
