I had a rather odd issue with my central heating and air conditioning system when I first bought it.
It was too strong and powerful! I know that is an odd thing to say as you would want the central heating and air conditioning system to be powerful. But this was just way too powerful. I actually had to call the heat and a/c company that I bought the HVAC unit from in order to see what was going on. Because I could not deal with this central heating and air conditioning system the way that it was. Either they had to figure something out or I would have to return it and buy another central heat and a/c unit from another heat and a/c supplier. The heating and cooling company I was dealing with would not like that so they sent out a certified heating and cooling specialist for free to come and see what was going on with the HVAC unit. The HVAC unit turned out to have not been set up right. Heating and air conditioning set up is very important in the installation, and the original heat and a/c specialists did not get it right. So the heating and cooling specialist that they sent out was able to complete the HVAC set up properly and then my central heating and air conditioning system was just right. It was no longer too powerful but just right as it should have been from the beginning.
