John did fine for what the good Lord gave him to work with. John can only do as well as his training. Absolutely NO ONE AT ANC knew how to fix the problem which was recalibration of the IFT RC400 remote. I myself looked it up online through thorough study and explained to him how to do it. And it worked! So I said to him before he left, “Now you can train the rest of ANC in how to do this”. Those remotes are around $400 plus ANC TRIPS about another $230. So I only had to pay $230 but it’s mostly because it took time. ANC had basically waisted my time with uneducated employees at ANC’s prices to charge me. You figure it out!

I called ANC because my AC stopped working. It was on a Friday and was a very warm day. They sent out 2 young men who took one look and advised me that it was "frozen up" because there was a leak in the coil. They told me the refrigerant level was very low and said it would do no good to simply refill it. After disputing that the warranty was no longer in effect, I produced the paperwork proving that it was indeed in effect. They photographed the paperwork and evidently sent the photo back to the office, where the owner agreed that they would honor the warranty. They told me the new coil would have to be ordered and they would advise me when it arrived and they would schedule the work. After the system thawed out, the AC began working on it's own.
I then received an online estimate of $1800., and that did not include the part. That was enough for me to get another estimate. The people I called for that estimate came out and discussed the issue with me, but said they would need to do some diagnostics before giving me any estimate. ANC did no diagnostics except evidently "checking" the refrigerant levels. The second company ascertained that the refrigerant was almost gone and that there must be a leak somewhere in the line. So they brought the refrigerant up to correct level and put dye in the system to identify where the leak was. My instructions were to run the system for 4 days to let the dye work it's way through.
It all worked fine for the 4 days. When company 2 came out to check for leaks, there were NO signs of any leaks, and the refrigerant levels were fine also.
I have notified ANC that I do not need a new coil. I will let you come to your own conclusions about why this all happened. I suppose if they had replaced the coil and refilled all of the refrigerant, it would have appeared to this consumer as a "job well done". And they would have $1800 in their pocket.
