"Peerless Lemon"

Every year its the same service call ending up with a cost in the hundreds for service and part replacement. Now the computer board has gone down. A major cost to replace – screw it time to replace the unit with another boiler company.

The unit is 8 years old. Writing my annual $1,000+ check to my installer. This year f18 error code. Replaced gas valve ($700) — nope. Replaced the connector ($100) — nope. Replaced the control board ($??) — finally worked. Two weeks of cold. I replaced a working Weil McClain with this Pinnacle for efficiency — so dumb. If the control board didn't work, my installer planned to dump the Pinnacle. Easily have $6,000+ in repairs.

"Bad product from the beginning"

I bought 3 Peerless Pinnacle boilers and had them installed by licensed hvac contractor in my new home 12 years ago. I have had nothing but constant problems since the first day they were installed. Contractors practically lived at my house for first 3 years. High repair bills and constant breakdowns. They finally started leaking in the coldest part of the holidays all over my basement floor. I would warn anyone from ever buying a Peerless product. They are the worst. And it wasn't hard water or incorrect installation. Its the same problems everyone has had for many years with Peerless. Bad product and no support. Only excuses. Avoid these boilers at all cost. You will regret it otherwise

Everyone reading this review and the dozens below should realize we all got screwed by Peerless. I owned 3 of these Peerless boilers all installed in a new home I built. The local hvac contractor which was part of the builders stable of preferred contractors installed these 3 units(nicknamed munchkins) in 2005. From the first week we have had nothing but trouble. The contractor has been at my house at least 10 times a year for the first 5 years. After that it was 6 or more on average per year. He could have had his own key to my house for the first year or two….he was at my house that many times. My contractor admitted after about 4 years that this product was junk and Peerless discontinued them shortly after mine were installed. 3 years ago one of the boilers electronics broke. My hvac person told me it was not worth it to repair, so he used it for parts to keep the other 2 units running. Last week the remaining 2 boilers started leaking from the heat exchanger within 1 day of each other. No heat in the subzero weather of 2017 Christmas -New years week. All because Peerless made faulty products. I replaced my faulty Peerless products with Dunkirk Boilers with a 20 year warranty on the heat exchanger. Its clear from the dozens of reviews they were faulty and we all couldn't have had them installed incorrectly by so many different expert contractors as Peerless will most likely claim. Please join the class action lawsuit: write to Kevin Kwiatek 56 West Main St Glen Lyon, pa 18617 He has written a review below and asked us to join his efforts. Please write to him. We have nothing to lose. I would like some compensation for the thousands of dollars I have spent in contractors bills and replacement parts as well as 3 new boilers installed last week. These products are bad and we all deserve some compensation for our problems. Please join the effort. I am writing Kevin today.
