I have previously had two Generac house generators. They ran, but did not last long. Got 6 years out of the first one and 4 on the second one when I sold the home. The Trane is an automotive grade engine and common sense tells you that it is better then the riding mower style engines in the Generac.
I've had the Generac brand before and this is a far superior product. It has an automotive engin...
I've had the Generac brand before and this is a far superior product. It has an automotive engine and is supposed to last 20 - 25 years. My Generac lasted 6. It is well worth a little bit of extra money.

This generator is produced by Chongqing Panda Machinery Co (based in China). (see google "PD20REG" is the generic generator and "TR20REG" is the Trane rebranded unit) Trane has simply slapped their logo on it. It is complete trash and is not even UL Listed. If you live in a city where the Inspector requires UL Listed generators, you will be completely out of luck...especially since it say "no returns" Also the enclosure is painted steel and will become a rust bucket within a year.
I should never have purchased this generator.

Dear Valued Home Depot Customer,
We have reached out to the manufacturer and their reply is, This generator has a powder coated finish that is designed to resist rust and last for a very long time in outdoor conditions. Also, to your comments regarding the UL rating, it is actually ETL and CETL listed (which is an even better rating). For any cities that require a UL listing, ETL goes above and beyond and will satisfy any requirements. Thank you for your interest in our generator and let us know if you need any assistance with installation!

a terrific whole home generator
this was a replacement for a generator that caught fire. its safe, dependable and sophisticated ... makes the other look like a toy

My house is prone to flooding and power outages and I can't take a chance ... so Trane was a natural. My experience with their HVAC equipment was excellent and I knew they'd make a really reliable top tier generator. And then, without my asking, the electrician / installer started raving about how much better this generator was than others he's installed. The generator not only saves you in a power outage but it adjusts for normal swings / spikes in utility power and protects against damage to sensitive electronic devices in your home. Its been a lifesaver for me and some neighbors ...I'd recommend it without hesitation.
