One thing I can not sit and that actually bugs me is when I make an Heating, Ventilation plus A/C appointment with our local heating and a/c company for a particular time. And then when that time comes, the certified heat and air conditioner specialist that is supposed to perform whatever heating and cooling work I need done is late! Especially when they are more than a half hour late! It actually jacks up our day and messes things up. I can understand if they are late due to some circumstance love their heat and air conditioner truck breaking down on the road or some other traffic or vehicle issue. But when they are late simply because they did not pay attention to their schedule or some other heat and air conditioner appointment ran overtime, I get mad. Because they should not have grabbed the heat and air conditioner appointment if they were not sure if they would make it on time or not. This is a single reason why I appreciate to call independent heating and a/c specialists over a local heat and cooling company. Independent heating and a/c dealers seem to be more on the ball than the local heat and a/c company because they are their own bosses. They are not having to work with employee Heating, Ventilation plus A/C specialists. I have never had an issue with independent heating and a/c dealers. But noy oh boy have I with local heating and cooling companies. That is why this week I use nothing but this a single independent heating and a/c company who is the best!
