Getting too immense of Heating & A/C equipment

I made a mistake when I obtained my Heating & A/C equipment.

I did no research & did not consult with any Heating & A/C companies except for the a single I hired.

The Heating & A/C company came in, measured my home & then quoted me a price. I blindly paid & got my heating & cooling system put in. Now that I have had the Heating & A/C for over a year, I realize that I messed up. I have an Heating & A/C component that is too big. What some Heating & A/C companies do is rule of thumb. They take a loose measurement of your home & then pad up the numbers for human error, then my Heating & A/C business absolutely padded them up & gave me a much too immense unit. It was more of a commission rate for him, so that is why she pushed me into it, and having too immense of a component is not good, it wastes so much energy. The Heating & A/C achieves the temperature on the control component super quick. It fully powers on & off numerous times a day. It runs full blast & then totally shuts down. It takes a lot of power to do this & as a result, my utility bills are skyhigh. I can hardly pay for heating & cooling because of it. If the Heating & A/C was the right size, it would be a steady stream of heating & air at half the cost, however but, now I am stuck with what I obtained. It is fancy buying current Heating & A/C. I also don’t suppose how to make the immense Heating & A/C run effective for my small house.
