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.

However, dampers on return ducts are not a necessary addition for most homes.</p></div>

Q: How can I lower the humidity in my house fast?

• <div><p>To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.</p></div>

Q: Should I replace my evaporator coil or the whole AC?

• <div><p>While it&rsquo;s possible to only replace an evaporator coil to keep your AC running, this could cause issues down the line. An AC system relies on the harmony between its condenser and evaporator coils for efficient operation. Replacing only one coil, especially in older units, can cause compatibility issues, leading to inefficiency and potential system breakdown. </p><p>As AC units near the end of their expected lifespan, investing in the <a href="https://www.angi.com/articles/how-much-does-installing-new-ac-cost.htm">cost for a new AC system</a> is typically better than paying for individual component upgrades to avoid costly repairs and ensure optimal performance.</p></div>

Q: What signs indicate it’s time for a professional A/C unit service?

• <div><p>Poor cooling, unusual noises, or frequent cycling are indicators that professional service is needed.</p></div>
