Q: What are the signs of mold in an air conditioner?

• <div><p>One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.</p></div>

Q: Can I put furniture in front of a return air vent?

• <div><p>If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. </p><p><a href="https://www.angi.com/nearme/duct-installers/">Professional duct installers </a>suggest leaving between <b>six and 12 inches</b> of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system. </p></div>

Q: Should I turn off my AC if it's not cooling?

• <div><p>If your AC unit isn&rsquo;t cooling and you haven&rsquo;t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.</p></div>

Q: Do Florida rooms have heat or air conditioning?

• <div><p>Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens. </p></div>

Q: Is it OK for my AC to run all day?

• <div><p>If you have central air conditioning, it&rsquo;s fine to <a href="https://www.angi.com/articles/how-long-ac-can-run-continuously.htm">run your AC all day</a> if that&rsquo;s what you want&mdash;as long as the AC unit is in good condition. But if your AC runs constantly when you don&rsquo;t want it to, there may be a problem with your system (like the ones we&rsquo;ve mentioned above). Window AC units and wall air conditioners aren&rsquo;t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time. </p></div>
