Not even a year old

We have only had this unit for about a year. The technician finally pinpointed the problem yesterday and is going to order the kit to fix it. We have learned that RUUD has been aware of this particular issue with the compressors for a long time.

Ruud U97V modulating ultra series

I am a Heating contractor. I chose the modulating because I love toys and also love my comfort and love my money. My preferred Furnace is Ruud since I switched over in 2004. Reason being reliability and I never go back for a repair. Homeowners should need to know the installation of the furnace is extremely important. As well as don't get a furnace installed on the lowest prices contractor most likely they will find a way to save on installation cost. I only recommend Ruud and as competition Lennox. The rest I don't like the call backs after a proper installed Furnace. Best of luck and skill to everyone.

15 years

Not one problem in the 15 years we've owned this Ruud Achiever 90. Half if not more of those unsatisfied have more to do with installation failure than the unit.

Love it

Wanna say a big thank you to Rheem! I have a Rheem CNRHE 50 high efficient condensing water heater, and of course my Ruud/Rheem furnace. These guys now how to build gas appliances. Never a problem, always there doing their jobs. Frankly, I agree with all the bad reviews or clearly poor installation issues. A furnace replacement is not a plug and play situation and I would be offended if an installer would try that on me. My unit was sized properly, some ducting was resized and my return air ducts were increased considerably to make it right. My water heater needed a lot of consideration for a proper install. Yes, these things cost more to have done, but it is important, and yes, you as a consumer that is looking for cheap cause your own problems. Overall, a Rheem / Ruud customer for life here and a big shout out to my installers that take their jobs seriously!

Blower set screw

I am a service technician and over the past couple of years I have had to change out the blower motor and wheel on two units and an entire blower assembly on another. The cause? The set screw used to secure the blower wheel to the motor shaft was too short(factory installed), by at least a 1/4 inch. The blower wheel eventually began to slip around the shaft, wearing a groove in the shaft and then the hub wallowed out and caused everything to be out of balance. The cost of repairs was an expense my customer should never have had to incur. Shame on ruud, another few pennies for the proper length set screw on their part would have saved my customers $200-$300.

Would not recomend

I had this furnace installed 5 years ago and I have had the service guy here every year for five years. I was told when making my original decision that with this furnace I will never see the installer again, it is just that good. We'll Good thing I like the guy cause I see him a lot! Main issue is the sensor carbons up. He tells me it needs to be cleaned every year. So basically I am to pay $150 a year to clean a sensor that takes them about 2 minutes to clean. Chances are it will carbon up again during the heating season. How cost effective is that? Sounds like a bad design issue.

I contacted Ruud about freezing off problems, and all I received from the manufacture was: Oh well big deal duh we don't know what to do. Every winter the Achiever plus freezes off -- plugs with ice and shuts down. How does a person go any place when you cannot trust the furnace you were told was a good top of the line unit? The installer would not even come back to warranty anything so if your considering a Rudd give me a call you can have mine because I am ripping that piece of garbage out of my home, and installing a unit that can handle cold weather.

It would have been cheaper to burn dollar bills than fixing this thing. It is only 6 years old and I've put in over $1000 into it. And of course it always fails on a weekend.

I have owned this Ruud 90 plus furnace for approximately 10+ years. I have had service on this unit approximately every other year. As I have heard before problems seem to be minimal nevertheless it keeps it from functioning properly. I live in the upper mid west where the temperature drastically changes from day to day and I cross my fingers when I have to use this unit for heat. I would not recommend this Ruud FURN/Achiever 90 Plus unit.

Can't beat a Ruud!!!

Most of these reviews are bogus and self inflicted by poor installation!!! I installed a Ruud furnace in my house 22 years ago when I bought it, the first season I blew a board, I thought well it can happen so it was replaced under warranty. :] The second heating season same thing blew another board, crap, but it was covered under warranty. The repair man suggested I have my electric box checked because these boards just don't fail like this. Sure enough my ground circuit was loose and 20 years later same board furnace is great. In those 22 years I replaced one hot surface box and 2 ignitors.

Very Satisfied

Had my furnace installed by a professional company and couldn't be more pleased with it overall. Great system and cut my gas bill by 25%! I read all the negative reviews and disagree with most of them. If you don't maintain them, they will give you problems, just like a car. Take 20 minutes to read the owners guide and you'll get extended life out of most products you own. I will be replacing my a/c unit this spring with a RUUD product as well.

Look elsewhere

Achiever 90 Plus model good for the first couple years, then problematic. Latest issue, we needed a 2-foot rubber drain hose. So what's the big deal?... You must get all parts from an authorized service provider due to "safety risks". Sounds more like protecting service providers income to me - how about you? Anyway, 2-foot hose with service call would have been $100.00 +/- (we substituted with $3.50 hose from Lowes - hope ruud didn't force us into a safety risk situation). Ruud/rheem won't even give you the part number, or provide a parts list!!!! Whatever unit you buy, make sure parts are available over the counter to the owner, or require installer provide a parts list and service manual as part of the installation contract.

Poor Quality Product

Had a new Ruud Achiever 90 Plus professionally installed with a new a/c unit in 2005. In the five years it's been in my house I've had more than 12 failures when it's 20 degrees or below. So far two circuit boards, 1 pressure switch and 1 ignitor have failed. Please do research when buying major appliances, I trusted the installer for quality products- big mistake.

Rudd Achiever 90 Plus

Installed a new Ruud Achiever 90 plus 75000btu 91% 12 years ago when house was built. The only issue was a burnt out blower motor that I replaced 2 years ago. The unit did not start on one instance but that was due to snow (heavy winds) clogging the outside intake pipe. Overall, I'm pleased with the furnace thus far and is considering replacing it with a higher efficiency (95%) model and to take advantage of rebate incentives.

We have had the Achiever 90 Plus for 4 years. It has not worked properly after the first year. We can not leave overnight during the winter because you never know if it will work or not. The installing contractor is now blowing me off and not responding to messages. From most of the other reviews that I have read, it seems like a class action lawsuit may be in order.

Very Disappointed

Had a Rudd Achiever 90 Plus with dual comfort control installed in Feb 06 and have had nothing but grief with this furnace. First service call Mar 06, 2 service calls in the winter of 07 and just called again Dec 08. This furnace will not keep running, comes on for 10 secs then shuts down then comes on after about 1 min then continues this cycle. The company that installed it says they need to come and clean the furnace every year or the warranty is void. What a crock. They want $75.00 every time they come out. We have owned several homes and have had 2 furnaces replaced before and never once had to call for service even on the furnaces we did not replace. I will never buy another Rudd product. We saved over $200 on our heating bill every year but paying $150 on service calls doesn't add up to much savings.

Other Achiever 90 Plus Reviews revealed a post from an owner whose flame would die out immediately. Another homeowner wrote that he had corrected a similar problem by replacing a drainage tube, which had become obstructed.

Another Ruud Achiever 90 Plus furnace owner writes to the experts at about the blower running, but no heat coming out of the vents. The contractor was able to discern after some discussion that the problem was probably being caused by condensation in a drainage tube once again. The expert stated this was a problem he rarely saw in many years of working on furnaces.

A homeowner writes on about problems with the Achiever 90 Plus not staying lit. A solution is not reached on the forum, but some responders feel the LP gas tank may need to be filled to increase the pressure.

A recent post on also mentions the issue of the burner going out. The consumer reports that the venting outside was at an incorrect angle and wind was entering the system and causing the problem.

Question and Answer


What does a green flashing light mean?


This flashing light is indicating an error code based on the number of flashes. In your owner's manual or on the inside of the cover panel or perhaps on the furnace itself there should be a description of how to read the code and what each code means.


The furnace wouldn't kick on last night. The ok light flashes twice. It doesn't try to purge or ignite. Fan works.


Many times the air filter can be clogged and prevent airflow. If after replacing your filter your furnace continues to have issues you should hire a licensed contractor to look at the unit.


Where is the pressure switch for the Ruud Achiever 90 Plus located?

Blinking green light, alarm states the pressure switch is open and to check it.

See page 2 of the manual for the location for the pressure switch on your Ruud Achiever 90 Plus. There is a picture which shows it in the middle of the unit.


Where is the limit switch on the Achiever 90 Plus?

Owned 15 yrs but hardly used because we burned wood only backup and absence times. we started it this fall and began this. turn thermostat up and fan wants to start before it ignites. cleaned board and ckd what could. no service manual given when installed. think it may be limit switch.

Page two of the user manual identifies all the major interior parts. When it comes to working on a furnace I strongly recommend hiring a licensed contractor (due to the potential harm you can cause). Licensed contractors spend years in school and doing on the job training. So if you're unsure of your abilities, contacting a contractor is always a safe bet!
