Honeywell HM506H8908 Truesteam Humidifier, 6-Gallon

Contractor warned me that he was having issues with the Honeywell steam humidifier. Claimed I would be lucky if it lasted 3 years. Thinking I could live with 3 years, I had him install it. I really wanted a steam humidifier. Well, it last a little longer than 3 weeks. Contractor brought me a new one, and same thing. I am now in process of installing an Aprilaire which cost a few hundred more. Honeywell, you should pull this product from the market.

I had no option but to buy this product. My new furnace was in such a tight space that they could not install a conventional humidifier unless it voided it's warranty.

SOooo it's Truesteam or nothing. Let me say that it humidifies better than any other humidifier but it is NOT a set it and forget it product. First, it has to be installed correctly (esp.the wiring). If you have the chops do it fine , but otherwise get an HVAC dealer to do it for you. Second, get a Honeywell Reverse Osmosis Filter System (about $200 & easy to install)to go with it. This will save you time and $$ down the line. I went 2yrs without one and the scaling and cleaning and replacement of the water sensor unit ($60) each year was a pain...and my softened water is not that bad. Third, an probably most important, get to know your troubleshooting manual (Honeywell has a video that's pretty good as well [Google: Truesteam Tuneup]). If you don't you will have endless service calls because the warning lights go on and the unit stops working 2-4 times a season and you have to diagnose the problem. The blinking warning light system will tell you 95% of the time what the issue is by the # of blinks. Since I'm now an expert it's easy to get it going again.

Bottom line..I love the way it humidifies. Very even and efficient since my fan is on all the time. Better than Aprilaires I've owned. BUT.. you have to get to know the unit. If you don't you WILL get frustrated. I don't look forward to selling my house and explaining this to the new buyer.

UPDATE: I inquired about the APRILAIRE 800 Steam Humidifier (Hey..if it works better I'll try it) and was told by their #1 dealer in the area that the Aprilaire rep has told them to stay away from the unit...too many unresolved problems. Translation: endless service calls. Like with Truesteam the fixes are probably not difficult but the average homeowner doesn't want all the maintenance issues.

This is the worst purchase I have ever made. Neve has worked right. Have replace the entire unit and it still doesn't work right. If you don't have a good water source the boiling water will leave deposits from the boiloff. These deposits will cause the solenoid to malfunction and have to be replaced. I have done so several times. This is a hunk of junk.

I bought this unit on the advice of my HVAC man in 2008. To be fair, and this is the only good thing I will say about this unit, it does a good job of humidifying the house WHEN IT WORKS! The damn thing is made of plastic and is CONSTANTLY splitting (water tank) and or cracking (senders) after every heating season. Something is always broken on this piece of s _ _ t. I have had 2 brand new units replace successive faulty units but they all end up falling apart again. What the hell was Honeywell thinking of when they made this thing out of plastic?

It is November and time to start humidifying in the house and the unit water sender is once again cracked and broken. So I have a truesteam unit mounted on the ducting doing nothing. My HVAC man is bringing another water sender which will likely be junk at the end of the season.

My advice to anyone thinking about buying the Honeywell Truesteam STAY THE HELL AWAY FROM IT! Save your money and look for something that is NOT made of plastic. I don't know about the Aprilaire units, but I think it's time to look at them. Honeywell should be ashamed of building this kind of garbage. I hope this review prevents at least one person from wasting their money on this product.

Read the other reviews for this humidifier and you'll understand why it's a bad product. I'm on year 4 with mine. Its horrible to clean. The tank and seal already had to be replaced. Now, I get a water sensor error code that will require a call to the dealer. The parts warranty is 5 years which is good. The bad thing is it doesn't cover labor. I bought this to save water over the traditional water wasting type. What a horrible choice I made!
