"Information On Class Action Lawsuit"

1.0 rating
Very Unsatisfied

If anyone is interested in looking into a Class Action Lawsuit against Peerless for their Pinnacle Furnace Please send your information to me. Kevin Kwiatek 56 w Main Street Glen Lyon pa 18617. If I can get enough responses I will seek out an Atty. who would represent us. I am tired of putting up with the constant breakdowns. Peerless was deceitful in putting their name on a boiler they did not manufacture.

"Peerless boiler is junk."

1.0 rating
Very Unsatisfied

We purchased this Peerless boiler a few years ago. I am now on my 3rd combustion blower at $400.00 each. Replaced the electrode and flame sensor and this boiler needs to be cleaned a lot. I service heating systems and this one is very expensive to operate. Stay away from these things. I also installed a camera to monitor the boiler when we are away. Can't trust this thing. We have wood heat for primary heat source and the peerless is only used when we are away or in the summer for heating water.

"Piece of Trash"

1.0 rating
Very Unsatisfied

This boiler is garbage. This boiler went haywire and needed a new blower motor and some other parts after the first year. Also, numerous emergency service calls for faults and failures. Expensive to buy and have installed. Ridiculously expensive to repair and maintain. I have spent more on repairs and maintenance than the original cost. Now it's making an awful and loud rumble and vibration at ignition, sounds like its going to blow up. Just thinking of yanking it out and starting over with a different brand. I originally bought this because I was led to believe it was the best out there, yeah . . . right.

"Completely unreliable"

1.0 rating
Very Unsatisfied

Bought the unit in 2008 for a vacation home in MI. The unit worked for 1 season then crapped out. Replaced the mother board and the flame sensor. Stopped going to the vacation home in the winter due to its unreliability. I would never purchase another Peerless product nor would I recommend it to anyone. I would be happy to join a class action suit against the company.
