So disappointed :(. We were warned to watch out for companies that do not automatically come back to add freon after installation (Hendel's did not do this until we called about problems with our unit 6 months later). I guess we should have listened.
After problems about a year after installation, our Hendel's technical then informed us it was wired incorrectly so the system was not working properly. 3 months after our 1-year labor warranty expired, the coil bursts...and they will not cover the labor or freon related items, which adds up to a nice chunk of change (despite a history of problems).
We have been disappointed in their customer service. You do get the feeling they would prefer you simply go somewhere else if you experience problems. When it comes to communication, it took us a lot of effort to maintain contact and get updates from them each time we had problems. For example, we called them for updates a few times yesterday (we cannot live in our house with 2 kids and 1 on the way, so we were hoping to get a target date for moving back) - each time we called yesterday, they expressed surprise that we had not yet heard back from them with updates (although we did always get promises of a "call right back")!.
I so wanted to like them and had handed out their cards to friends - their technicians seemed great - but I've since had to call those friends to take back my recommendation.
Who wants to use a company that informs you your new AC was not installed correctly in the first place? Whether it was related or not, it is disconcerting...and customer service showed no concern about improper installation since "that's something totally different."
