The old me would have gone in like Tony Soprano. Now that I'm old and mellow, I'd let it go. Write a factual, emotionless review and see if they contact you to make it right. If not, don't use them again.
I hear you, and I did calm down a bit over the last 24 hours. The HVAC company called me back this morning and I had a very calm conversation with them.
I prefaced it all by reminding them that in the last 3 years, I've given them more than $20,000 to install 2 ACs, 2 furnaces, and 2 water heaters (for my home and my son's home), and that I've been a member of their home care club these last 3 years.
Then I reminded them that their tech came to my house 2 weeks ago to do the annual checkup on my AC unit (this annual checkup is covered by my home care club membership).
I explained that since they hadn't called me back after I reported the problem Friday evening, I managed to solve it on my own. I explained the problem was caused by their tech when he came to my house 2 weeks ago. After checking out the outside AC unit, he reinserted the breaker switch into the power box upside down.
They apologized profusely and said they would have a conversation with the tech. I told them to not be too harsh on him because he was very nice and professional, he just forgot to put the breaker switch back in correctly before he left.
They apologized some more and said they would send me a restaurant gift certificate for $100. I guess I'll believe it when I get it.
