Q: How do I extend the life of my window AC?

• <div><p>To make the most out of your AC, consider implementing the following best practices: </p><ul><li><p><a href="https://www.angi.com/articles/what-size-ac-unit-do-i-need.htm">Choose the right size AC for your home</a> to ensure your unit runs as efficiently as possible.</p></li><li><p>Choose a window with shade, as direct sunlight can cause your AC unit to overheat. </p></li><li><p>Clean or replace the filter at least every two months. </p></li><li><p>Inspect the AC&rsquo;s fan and straighten it if necessary. </p></li><li><p>Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. </p></li><li><p>Turn off (or adjust the temperature) when you leave the house. </p></li></ul><p></p></div>

Q: Do return ducts need dampers?

• <div><p>If you know <a href="https://www.angi.com/articles/how-to-identify-supply-and-return-ducts.htm">how to identify supply and return ducts</a>, you&rsquo;ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it&rsquo;s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.</p></div>

Q: What size window AC do I need?

• <div><p>The size window AC you need depends on the BTU and the size of the room you&rsquo;re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don&rsquo;t overshoot the BTU for a small room, or you&rsquo;ll waste energy and have higher bills.</p></div>

Q: Do scorpions come through AC vents?

• <div><p>Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.</p></div>

Q: Is it normal for my air conditioner to leak water?

• <div><p>Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your <a href="https://www.angi.com/articles/will-homeowners-insurance-cover-water-damage.htm">homeowners insurance can cover water damage</a>.</p></div>
