I've used Hendel's for years and have never had an issue. I have 2 units. They installed a replacement for one a few years ago and I use them whenever my other old unit has issues.
Just had a tech out tonight because I gave up trying to figure out why my old unit wouldn't come on. Arrived on time, and 30 minutes later I'm cooling my house again.
The techs I've had out over the years have all been courteous and know what they are doing.
I rarely take the time to give reviews as you can see but Hendel's deserves me taking the time to write this.
