Q: How long does it take to clean your AC unit?

• <div><p>The time it takes to clean your AC unit depends on factors such as its size, the level of dirt buildup, and the thoroughness of the cleaning process. A basic cleaning can take anywhere from 30 minutes to an hour, while a more detailed cleaning involving disassembly and deep cleaning may take a few hours. Make sure you allocate enough time to ensure all components are properly cleaned for optimal efficiency and longevity of your AC unit.</p></div>

Q: How can I tell if an AC vent is blocked?

• <div><p>A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.</p></div>

Q: Is it OK to cover air vents?

• <div><p>You might have heard that <a href="https://www.angi.com/articles/does-shutting-furnace-vents-improve-energy-efficiency.htm">closing vents in unused rooms</a> can help with energy efficiency, but it&rsquo;s never a good idea to block air vents completely. Fully closing vents can create a buildup of pressure inside your ducts, which can lead to leaks, holes, or other problems. Instead, you can shut your vents partially (between 50% and 75%) in unoccupied parts of your home.</p></div>
