I called due to my AC struggling to keep the house cool during the summer temps
Originally I was not shown any digital diagnostics but was told multiple times that the refrigerant was not low
First attempt was replacing the TXV, which I was told made no change
Then I was quoted for a coil replacement
I agreed and had that service done
Here is where the problems kind of escalated
To replace the coil refrigerant has to be removed, I was informed that I was actually low by 2lbs from a 5lb system
Not only that, the system performance was still the exact same after the coil was replaced... they confirmed this with their sensors
Then I spoke to the previous home owner who told me the coil was replaced just 2 years ago, so a coil failing that quick is almost impossible...
Everything pointed to the fact that the coil was not actually the problem at all and that this service was done unnecessarily
I ended up putting the diagnostics I was provided into AI which also had the same opinion that based on everything and my situation, the coil replacement was not needed
I had to call them back because their own diagnostics showed that the system was still performing poorly and there was a diagnostic test that was not done even from the beginning which would have actually proven whether the coil needed to be replaced or not
I figured out from the data I was given that the issue was the blower was turned to the max setting
As soon as it was adjusted then the AC system was performing correctly
So in the end the system was actually low on refrigerant and a simple adjustment on the blower was all we really needed
I was still charged for the full coil service, no discount
To this day we can't say for certain that the coil replacement was necessary and there was no change in the system after it was replaced
The main change occurred after our blower was adjusted...
Had the FULL digital diagnostic been done from the beginning I would have concrete data, but instead I was only provided with a digital diagnostic after the coil replacement
Before the coil replacement I was only shown a hand held analog device which had a small amount of data and did not actually show that we needed a new coil
I do feel like I was ripped off and regret not getting a second opinion before going with the full coil replacement, which came out to 1700$
I do appreciate the honesty ( which is why this isn't a 1 star review ), they didn't have to admit that we were actually low on refrigerant and that the temperatures were the exact same before and after the coil swap
They did return to make the adjustment to the blower when I called, but it should have been done before leaving to be honest
In the end I still feel like I should not have been charged the full coil replacement price, based on everything that happened....
Because it looked like all we really needed was a refrigerant refill and a blower adjustment which should be have been a couple hundred at most....
-1 for not providing full digital diagnostic from the beginning
-1 for charging me the full price even after we all saw there was no change in the system after the coil swap read more
