One of our General Aire humidifiers was a mess inside with mold and crud after sitting idle all summer. So. no need to replace the whole unit. With the parts kit, we were able to change the guts and it is like new again. No static electricity or dry skin and hair in our house. Thanks General Aire

This tune up kit was just exactly what we needed. I've been good about maintaining our humidifier unit, but after 10 years of scale build up, it needed more than general cleaning. All the parts were there and installation was very easy. I would buy this again in an instant.

Review: General Aire 81 Tune UP Kit by Jon (Johnstown PA US)

No problems and everything arrived on time. The key parts I was looking for was the valve assembly and the replaceable filter. The old valve on my systems leaked. It was better to get the additional pieces and change everything out at once. Very simple change out with current system. Might have to adjust valve height depending upon water level but that is just how the system runs. Everything has been running without a problem. I am going to buy some additional filters to have available as needed. I would recommend this kit to anyone with a system just to replace parts over time. I live in a hard water area and it shortens the life of rubber gaskets and filters.

Easy DIY Rebuild by Albert Toth (Royersford PA US)

I only use my humidifier in the winter months. I give it a good cleaning when I shut it down each year. After eleven years, it was time to replace the plastic and rubber parts that have become hard and brittle with age. The tune up kit did the trick. The parts arrived quickly and they were easy to install. This is a DIY job that will save you a couple of hundred dollar when compared to your HVAC service.

We haven't had a chance to install the kits as yet but , from the reviews we read, it shouldn't be a problem. We saved a lot of money since we thought that we would have to replace the whole unit. Thanks, General Aire, for making life more affordable for your customers.

General Aire 81 Tune Up Kit by Phil Deterville (Buffalo Ne US)

I am very pleased with the Tune-Up kit, and had no difficulty installing it on my furnace. The replacement parts have really made a difference in keeping moisture in the air on those bitterly cold Buffalo nights! I thought the cost of the Tune-Up kit was very reasonable for all the parts that it contained. However, in order to keep from having to replace the parts again in a few years due to build up of calcium, I have installed a water filter in the supply line. I will let you know in a few years if this has made a difference! Thank you for making this kit available.

great set of parts by mike dotterer (sewell nj US)

Exactly what I needed to make it come to life again. We moved into a house where the previous homeowners had used the humidifier for a few years and then just shut it off. It was nasty and obviously un cared for. This kit replaced everything we needed to make it useful again. A piece of plastic for the float's on/off switch needed to be filed down a bit to keep it water tight which is why I gave it 4 out of 5. Simple fix, however, I didn't know what to do and had to get help from a family member (I'm not handy). Otherwise, it was perfect.

What a find! by Mike (Harrison Twp MI US)

Parts are same as those that came with the humidifier installed in my newly constructed home 21 years ago. Great way to rejuvinate your humidifier and get rid of those cruddy lime covered parts.

tune up kit by Umbert Orlando (New Baltimore Mi US)

Would be nice if you could include several replacement rubber seats that is part of the float assembly. At one time you could purchase this part at sears. I don't see it in your available spare parts listing.

general aire 81 tune up kit by Jeanne Dunne (St. Clair Shores Mi US)

We just purchased our home with the general air 81 already installed. It was old and crusted up with mineral scum. I tried to clean it the best I could. I went onto your sight and found everything that I needed even a direction sheet on how to take it apart and put it back together. After we cleared the clogged water line and installed the new kit it ran like new. Shipping was quick and the order was complete. Many thanks, I will be ordering again.

What I needed by Brad Walters (London On CA)

Just want to say that i wish I had thought to check the website sooner. Was planning on just replacing our original Humidifier since we had so much calcium build up but decided to look to just replace the parts if I could find them. Normally I would just get what I needed at a local big box store and make it fit but the drum we had discarded was going to be a problem. Sometimes you feel like a fool when you find the solution is so simple. Once I checked the website and found all the parts I needed available in one kit, I was actually relieved, obviously I need to do this more often and replace these parts before I flood the basement again. The ONLY reason I am giving this 4 stars is that I am actually disappointed in the fact that my humidifier says it is made here in Canada but in order for me to get parts I needed to order them out of the US. Although far better than offshore, this is still a little troubling. As well, the only shipping option is UPS and anyone who has experienced their brokerage fees will know what I am talking about, USPS is a far better choice for cross border purchases in my opinion.

" helpfull pointers" by Robert Besso (Deer Park Ne US)

Thank you for shipping in a timely fashion. the only observation re: kit was that it did not include a washer which I had to take off my old unit & reuse. Also an instruction sheet suggesting that plumbers tape should be used on the reinstallation for the do-it yourself who might not know.
