I don’t know for certain if this is a fact or not, however in my experience when it comes to heating and A/C equipment specialists doing Heating, Ventilation, and A/C tune ups and check ups, when they take longer to do them and spend more time on it, it is of nicer quality.
I have had numerous HVAC specialists over the years do my Heating, Ventilation, and A/C tune ups and check ups, and I observed those who take up a few hours of time typically end up being the best.
Those who work roughly an hour are good, and those who rush things in around 30 minutes are usually those that do not catch everything and I end up having a heating and A/C equipment breakdown at some point over the next few months. This is my personal findings and experience and I could be wrong in what I am saying, however this is how it has typically worked out in my own experiences. I am not a heat and cooling equipment expert or quality assurance person by any means, however for all I really know for certain this is all just coincidence and I could be talking a bunch of false information about the heating and A/C equipment business. What are your personal experiences with heating and A/C equipment specialists, the amount of time they take when doing Heating, Ventilation, and A/C tune ups and check ups and what have you come to find? That would be what I am curious to learn, my next heating and A/C equipment tune up and check up is due next week. I will see how it all works out.
