My experience was different. I had them come out and evaluate my home for a new unit and estimate how much capacity I needed. I had already had three other estimates and they were all the same, so I was surprised when they said I needed twice as much. As soon as I mentioned the other estimates, they started back-tracking with things like, "Of course we want to make sure you're happy, but if you want to cut it close to the line..." and other typical sales tactics.

I asked about the warranty and they said it was 10 years, factory. I tried to look it up to confirm, but they never game me a specific model number. Installation was reasonable, and I liked the unit, so I agreed.

Installation was pretty typical if a bit messy. Then before leaving they told me I needed to register the unit with the manufacturer. I asked why they didn't do that and he said that they just don't. I spent over an hour trying to find where the serial number was (up underneath everything) in the heat. The company requires a fax or paper submission so I cranked up the fax machine. They said I had the wrong number, I needed to look on the other side of the condenser. So, I repeated the whole thing and got it registered. Five year warranty.

I should have listened to a friend who was wary of them because they advertise so much. "People that have a solid business don't have to spend megabucks on advertising". Good advice.
