Consumer Reviews of the Legacy Plus 90

We purchased our 1000sf condo two and a half years ago. We thought it would be a while before we had to deal with mechanical issues as the building was built in 05-06. At this point, the furnace would be roughly 14 years old. It should definitely have some life left in it. Had a furnace tech come out for regular maintenance/cleaning and discovered that the heat exchanger is bad. Turns out it costs nearly as much to replace that as to just replace the whole furnace! $3956 to repair it, $4770 for a new furnace. We’re probably going to shop around for a new furnace. It just so happens we’re selling our condo, I guess we can kiss goodbye to about 1/3 of our proceeds now. Thanks Bryant!

Good Old Furnace

We moved into our 1969 built bungalow in the spring of 2016. Everything was in order except our furnace had been installed in the spring of 2000! We thought we'd go through the summer with the unit in 'central air mode' and then see how it would perform during our first winter? This unit is a great performer! Two summers and one winter with no problems! I'm not a believer in spending money on service, but that just came back to me in a very inconvenient way. The unit would not keep running? It was our first cold day of the fall. It got down to 17 degrees f or minus 8 C. To make a long story short, I thought it was the 'pressure switch' but it ended up being the vapour/water trap! It was clogged with all sorts of 'gunk', but after a good cleaning the furnace was back to normal! Can't really afford a new unit, right now, as that would set us back $6000 to $8000! Hope this great unit 'trudges on' for another few years. So far so good! Thanks Bryant for making such a solid, reliable unit! Ken Canada

Inherited a nightmare

I bought a home with a Bryant 90 Plus's been in this home for 6 years and virtually every year this has given me problems and hvac bills. I was also informed that certain Bryant models have a recall for issues with the heat exchanger and silicon gaskets that have a fire potential. Sorry that I dont have more specific information on the recall but buyer beware. I would never want anyone to have to deal with these problems.

Bryant furnace lawsuit

My mother had a Bryant 90 Plus furnace that kept tripping the flame roll out switch. Turns out there is a lawsuit on all Bryant 90 Plus furnaces with certain model numbers after 1989. The engineer tried to cut corners and installed a secondary heat exchanger that was plastic coated instead of using a stainless steel exchanger (this has since been changed back to stainless in all new models). Keep in mind, Bryant will not own up to this as a recall, you must mention the lawsuit from the U.S. and Canada. Go online to look up the model numbers involved in the suit, call Bryant (Carrier Corp.) and give them your info. You must use a local contractor that deals with Carrier equipment and they will get the free secondary heat exchanger and 4 hours labor from Carrier. You should not have to pay any extra unless it goes beyond the 4 hours (which it most likely will, you're essentially dismantling the furnace). To get you by until the furnace man comes, crack the main manual gas valve back slightly to prevent trip outs on the limit, this will also help to reduce the temperature and that plastic burning smell. Of course you won't be at full Btu's, but you will have heat (what is happening is the plastic is warping on the metal heat exchanger causing a plugged condition). The furnace has a low and high fire position and when it goes into high fire it will trip out if too much gas is entering the chamber because of the plugged exchanger !

Poor Quality - Disappointing Response

Furnace's major component - main inducer motor assembly failed while being on warranty provided by installer. Unit was installed in 2008 and failed in 2013, just a week short from warranty to expire. Cost to replace was close to $600.00. Although warranty-5 years parts and labor was given in writing, the installer and Carrier refused to honor it. Total breach of contract, but no one seems to care. Had a previous furnace for over 20 years with no failure of any component. Stay away from this brand, if you can.

Cheap Blower Parts - Poor Manufacturing Response

We've had to replace the louvered blower drum twice in the first 6 years ($400+ ea, including labor) because they've disintegrated/fallen apart from normal use about every 3 years. Expecting to replace it yet again as we've passed the 8 year mark. The blower starts to make a racket for a day or two and then the blades just fly off. Clearly inferior materials and cheap spot welding. Additionally, we just had to replace the blower motor (almost $500). We've never had blower issues like this with other brands (Lennox and Carrier), twice as old as this. We contacted Bryant after the last drum failed and their response was, in essence, "so what, we think they're fine".

Energizer bunny

Bryant Hi efficiency furnace and a/c installed in 1989. Gas usage was about 60% of what neighbors used on either side of me. In 23 years, a/c failed in the first 3 weeks. Replaced immediately under warranty. No problems since. Furnace quit twice. First was frozen gas meter. Second was bird getting into exhaust fan. No other problems, nothing never.

Horrible furnace

I own a bryant model 350mav which is only 11 years old, the unit was installed by a professional hvac company and after the 5th year, I started having problems with it, first I had to change the inducer blower motor, then I had to change the control board, and now my secondary heat exchange unit is completely rusted and discharges a very fowl odor and rust in the utility sink. For an 11 year old blower, I have pretty much replaced every piece of equipment that needed to be replaced.

North East Ohio Bryant/Carrier system

I installed my Bryant Plus 90 (398aaz) 88,000 btu in 1990 when I built my 2300 sq ft ne Ohio home. I changed the inducer fan once, the ignitor twice, the limit switch once, the fan control board (module) 3 times (twice for lightning strikes) and cleaned the flame sensor 2 or 3 times when it got too dirty to let the furnace run, and tried to oil the fan motor. No place to oil it. I will just change it when it goes, which should have been 10 years ago! I do all the work myself because it is so simple. I run the fan almost all the time to keep the heat(cool) even. If it croaks tomorrow, I will put another one in just like it. Oh, it gives me a $70.00/month gas budget. I added a Carrier 3 ton ac unit 4 years ago, and have had no trouble with it at all. It is a little short on the 95 degrees plus days, but we only have a handful each year.

Other Legacy Plus 90 Reviews

Although the Legacy Line Plus 90 has limited reviews online, most consumers on are pleased with the Plus 90's performance. One poster on the site says his model breaks down at least once a year, but overall he's satisfied with repair and parts costs. Another writer on states the Plus 90 is a good, reliable option for a basic furnace.
