Comments about Tune Up Kit For Aprilaire Model 550, 550A and 558 Humidifiers:
Been using the Aprilaire for about 15 years, very reliable, never had a problem and it keeps our home comfortable in the winter. Usually only buy filters, but this kit made the unit like new. This humidity is essential if you live in a cold winter climate - keep skin softer, eliminate dry sinuses, nose bleeds and other problems from dry forced air.

I bought the tune-up kit for my Aprilaire 550 but when I installed that (which was very easy) I found that I also needed the solenoid part. I ordered that and it arrived very quickly. Once that was replaced the humidifier was up and running again. Great site, easy to understand instructions and everything you need to get your humidifier working again.

I'd hardly call myself a handyman, but it was very easy to install...even for me. It was exactly what I needed to get my humidifier working again. I couldn't find these parts in a store, but it was easy to find online at this website.
