Installing the correct size air conditioning unit for your home makes a significant impact on your comfort and energy bills. You might think that bigger is always better, but that is not the case. If you purchase an air conditioner that is too large, it will cool your space too rapidly. This will cause it to continuously shut off and turn back on, which leads to lower efficiency and higher costs and sometimes more broken air conditioner repairs.
On the other hand, if you choose a unit that is too small for your home, it will run constantly to cool the space, and in some cases may never achieve the desired temperature. This increases your costs and may leave you too warm in the summer.
