Trane Furnace common faults
I read a lot of these complaints, and some are easy to fix the problem. Example if your going thru ignitors, have your tech check the ground on the unit and maybe the house. Should cure that. Some say on high heat it overheats and shuts down and starts again. Ok duct may be undersized, filter clogged, A-Coil clogged with pet hair, dirt, etc. As far as brands go, Trane doesn't seem to have the class actions like a lot of them do. Believe it or not, it is not the evil equipment you may think, it might have an easier explanation. If you have one that works for a while quits and two hours later, the drain trap is clogged. When it finally drains down it allows the pressure switch to close and works till it's full of water again. Lighten up people… The dealers don't want it breaking down on you either…
Our compressor on our Trane heat pump/air conditioner. After 1 and a bit years. Even though we did not purchase the extra labor warranty because who could stop a TRANE. Laugh out loud Something did. And they don't even know what. Yes we got a new compressor, but the installation was 1500.00! So Trane has just lost many customers from our strata that just passed that the 61 units here could install them.
Very satisfied…excellent unit and very quiet. Had it for many years and no problems at all. Alfredo ..Jenison, Michigan
So recently, i purchased a couple Trane air conditioning units for the home. I was downstairs testing the home for the new winter in our new home and noticed that one of our current furnaces that came with the duplex was failing to fire. Not only is this a fire hazard, but it means it could be a cold winter for our upper tenant. I examined both units and they both appeared worn and used and the other one was likely going to fail. I went to Trane.com and found a unit that I really wanted. Ended up with the XL95. They were a little pricey, I'll be honest. But their multi-speed blower, auto mode for the fan motor, and super high efficiency has been amazing so far. We've had them for a few months and Wisconsin is just starting to get cold. I got the home down to 60 degrees and wanted to see how quickly I could get the home warmed up to 70 degrees. Took me 10 minutes to get us there and maintain that temperature. Overall, I am overly satisfied with these units and my tenants will be as well.
I purchased my Trane in 2013 from a local heating and air contractor. It was the greatest purchase I could have made. I live in SW Virginia, which means it gets pretty hot in summer and cold in winter as we live in the foothills of the Blue Ridge. It keeps the house cool in summer and toasty warm in winter. It's been known to get down to zero around here upon occasion. This really is a wonderful unit. It has a 10 year warranty which is really good. I would not hesitate to recommend it to a friend or to buy it again. Love it! It's Energy Star rated and has brought my electric bill down considerably. It was only $113.00 last month down from over $200.00! If you are looking to buy a furnace or heat pump I would highly suggest you look at Trane first. It's the best one out there by far!
