Q: Do I need a ductless unit in every room?

• <div><p>No, you don&rsquo;t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.</p></div>

Q: How do I know if my HVAC damper is bad?

• <div><p><a href="https://www.angi.com/articles/diy-duct-leakage-test.htm">Diagnose whether your HVAC damper is bad</a> by assessing airflow. For a manual damper, close it and run your system. Air should stop flowing through the associated vents. If you feel air, it&rsquo;s likely a bad damper that requires repair or replacement. Automatic dampers should maintain your desired room temperature. If not, they may be faulty, and you may need to invest in some <a href="https://www.angi.com/articles/how-much-hvac-repair-cost.htm">HVAC repair costs</a>.</p></div>

Q: Why is my AC blowing cool air but not cold?

• <div><p>If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.</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>

Q: How do I know if my AC needs to be recharged?

• <div><p>There are ways to <a href="https://www.angi.com/articles/detecting-refrigerant-leaks.htm">detect a refrigerant leak</a> with several different testing methods. However, most homeowners can figure out something&rsquo;s wrong with their AC unit by noticing these common signs:</p><ul><li><p>Ice forming on the evaporator coil</p></li><li><p>Water leaks near the AC unit</p></li><li><p>Frequent hissing sounds</p></li><li><p>Increased electric bills</p></li><li><p>Unit takes longer than usual to cool</p></li><li><p>Unit is blowing hot air</p></li></ul><p></p></div>
