Is it OK for my AC to run all day?

• <div><p>If you have central air conditioning, it’s fine to <a href="https://www.angi.com/articles/how-long-ac-can-run-continuously.htm">run your AC all day</a> if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time. </p></div>

Does setting the AC to 78 save energy?

• <div><p>Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. </p></div>

They showed up when they said they would, they worked in an efficient and professional way, and their price was reasonable. There was a misunderstanding at first about the finish, but they made the correction at their expense.
