Caution - first time usage
October 29, 2025Works great, but first time it was used, there was a burnt smell and smoke came out of the air vents! It happened just the first time in use. I believe the electrodes must have had a preservative on them. I used to work with heaters and air conditioners, so I’ve seen this before.
Yes, I recommend this product.

Best Product
October 29, 2025I had a Lennox for 28 years with only one problem, which was fixable when it finally died out. I of course, got another Lennox installed. and I couldn’t be happier. Lennox is the best product I’ve ever owned.
