I had got a brand new and modern central heating and a/c unit put in by this local independent heat and a/c business; all seemed superb once installed, but then a few afternoons later the entire heating, ventilation, and A/C system went crazy! It began making odd noises and it was not pumping out the air out of the air vents actually well, that’s when I called the certified heating and a/c specialist and told them what was going on, however they came back out free of charge to look at it since it had only been a few afternoons at most. And, I was fully protected under the heating, ventilation, and A/C upgrade protection plan this independent heat and a/c business had included in their policy. And lo and behold, the certified independent heating and a/c specialist said to me that she made an error in the upgrade and she particularly felt that it was disappointing. However, she ended up reinstalling my central heating and a/c unit at no additional charge because it was all her fault, plus she wanted to show that she wasn’t some quack and that this was a real human error that happened based on the misunderstanding of the type of home I had; this was completely understandable. My home isn’t your normal build I will tell you. So this made sense to me and I felt no ill feelings towards the independent heating and a/c specialist. She did a superb job in reinstalling the central heating and a/c unit and all was well moving forward. Have not had a single issue with the heating, ventilation, and A/C unit since!
