"Another broken block!! 2 Down!!"
Bought this new boiler 11 years ago and replaced the first block after five years and the second block lasted six years. They replaced the first block but I paid $2300 for installation. Now here I am awaiting facing the next install bill and not sure if the block is warranted.

"Quantum"
Originally installed Lennox Complete Heat unit. Had control board issues then failed after 3 years. Replaced with another but had to pay over $800 shipping and labor for warranty? Replacement. It failed 3 years later. Lennox discontinued so replaced with Dunkirk Quantum 090-150. I again paid parts and labor. Heat exchanger cracked and flooded basement 5 years later. Replaced and again I paid parts and Labor. Now 2 years later the control board failed and it will cost me $632 for the part and extra for labor. If this were a car they would cover labor and I would have the Lemon Law to use.

"Four Boilers in 9 years"
Brand new boiler in December 2003. In 2007 it blew a hole in it. They replaced it with the same make and model. Of course we pay for installation - $800.00. In January 2012 the third boiler again blew a hole in it. Makes sense -same make and model of the first two defective boilers. Why would the third boiler be any different? I could expand greatly on this! Bottom line these boilers were defective but yet they were still distributed regardless. I personally hope anyone who reads this passes this comment along with all the other negative reviews this company has had which totally supersedes the positive reviews.

"good boiler"
I was an early purchaser of this lennox quantum 90 hot water heating boiler. I get better than 90% eff.with the cast aluminum heat exchanger. I replaced the ignitor once (the company recommended a more robust ignitor). The 5/8 in transparent vinyl water condensate drain tubing plugged once last week and when water reached the ignitor the boiler wouldn't start. The drain tubing needs to be checked/cleaned yearly. I have never had to do other than the above service in 12 years. Its a good boiler.

"90% - 95% condensing boilers"
I am a hvac contractor in Philadelphia that has 25 years of experience. Most of the complaints that I get from heating system failures are from poorly installed or abused equipment. If the installation and maintenance instructions are followed, then it is highly unlikely that a problem will occur. The condensing furnaces and boilers like all equipment have certain requirements that if not followed can lead to unreliable operation. For example, the pvc pipe vent size, and pitch back to boiler is important to drain condensate properly: the dielectric fittings are needed to prevent a catalytic affect and deterioration of boiler fittings: the improper set-up of a boiler can cause misfiring of the burner and cause sooting of any boiler or furnace. There are 50 ways to kill a boiler or furnace if not following recommended installation requirements. I know that most products are reliable, however when installed improperly they can fail regardless of brand.

"Ownet"
We had our Dunkirk installed when we built our new building. Last year in the middle of January, the heat exchanger started leaking in the back. I called the installer and he said he would do what ever it would take to get it repaired or replaced. Dunkirk was called with this reply, "have the installer pull it out, send it to the distributor and they will send it to Dunkirk for review." They, in their sole judgement will check to see if the pH was correct in the fluid and make a determination if it was a manufacturers defect. If it was, they would replace the unit, send it to the distributor, then to the installer who would put it back in. If it was not defective it was $1700 for the exchanger. Guess what happened. None of the above because going three weeks with out heat would have frozen my bottom. I replaced the boiler with another brand that actually has customer service. Dunkirk is a brand I would avoid at all cost. So much for a ten year warranty. Zero is more like it.

"Don't trust Sears"
I bought a Dunkirk oil boiler through Sears 7 years ago. The unit worked fine until a few days ago when smoke started coming out. I called a technician because the Sears extended warranty had already expired (which I understand). The technician said that the heater exchanger is not working so we actually need to replace it. I called Sears and they don't seem to understand that when they purchased the unit, Dunkirk automatically provides them a 12 years warranty on the unit that we don't see because it's through wholesaler contract. Now, Sears don't want to help us because our extended warranty expired. They are so wrong, and it's Sears responsibility to replace the unit for us because we bought it from them not Dunkirk and the unit still has 12 years warranty. Sears is messing with the wrong people here and pretty soon they will find out if they don't help us. I will make it public, through internet and tv. I already contacted my lawyer, just to be ready so hopefully they move fast. The winter is around the corner...so just wait and see! By the way, I will never buy in Sears again.

"Lennox and Dunkirk both bad companies!!!"
6-7 years of agony with a Lennox complete heat and then this Dunkirk Quantum 90/150 for 6 more miserable years. Sitting here with no heat and hot water and outside temperature below zero. Have gone thru 4 igniters, on 2nd heat exchanger, 2nd circulation pump. My furnace company tells me to go out and buy some electric heaters until they can get a new igniter from lennox. Lot of love there. Its been over a week and they won't send anyone else out until they get a new part which they have no idea when its coming in. I'm almost ready to talk to my lawyers. Don't buy this boiler!

"Money Pit Boiler"
We installed this Q90-200 unit in our 4 unit building. We were suppose to save money on gas but to date we've spent more money on repairs than we did on the unit! If you do purchase this unit see if you can get a bulk deal on igniters because you'll need them. We replace at least once a year and as many as three times. Computer board, pressure switch, blower motor just recently 10/28/11 all replaced with the later at a cost of $968. Even after the new blower motor this piece of junk still locks out. The poor installer is sick of my complaining and his frustration intensifies with Dunkirk because they will not stand behind their product. He tells me not to feel bad because everyone else that he installed this unit for is having the same problem. That made me feel so much better! It actually appears to be a cash cow for him! Do yourself a favor and stay away from this company!! Anybody interested in a class action law suit?

"Has Never worked, even after they "fixed" it"
Three ignitors in the first year. I threatened them with a lawsuit, had the Carrier sales and technician representatives out, they rebuilt this boiler replacing any/all parts they deemed faulty. Now it burned out another ignitor! After reading all these reviews, it simply CANNOT be the fault of this single part. And yes, I know we have the "newly modified" ignitors. Please spare yourselves the agony. Get something else.
