Q: Is it better to have an AC unit on the roof or ground?

• <div><p>The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don&rsquo;t have existing ductwork, it&rsquo;s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. </p></div>

Q: Should I turn off my AC if it’s leaking?

• <div><p>Yes, you should turn off your AC if it&rsquo;s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.</p></div>

Q: How much does it cost to fix a leak in an AC unit?

• <div><p>Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">replace the AC unit instead of repairing it</a>. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it&rsquo;s nearing a decade old and has other issues, consider replacing it. </p></div>

Q: When should I replace my AC expansion valve?

• <div><p>A frosty expansion valve that isn't blowing out cool air is a sure sign that it&rsquo;s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.</p></div>

Q: What considerations do pros make for optimal A/C placement?

• <div><p>Assessing location for airflow, convenience, and minimal noise impact.</p></div>
