Is it normal for AC vents to drip condensation?

• <div>No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like <a href="https://www.angi.com/articles/moisture-leads-air-duct-rusting.htm">air duct rust</a> or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. </div>

• <div>There are several <a href="https://www.angi.com/articles/troubleshooting-common-air-conditioning-problems.htm">AC unit problems to troubleshoot</a>, but luckily you can identify them by keeping a close eye on your system.

Supreme Air did an amazing job installing this new Fujitsu mini-split system. They worked all day Sunday in the blistering heat to ensure we had AC that night. They are reasonably priced and their knowledge about mini-splits is second to none. I highly recommend them without hesitation.

Steve came out and discussed the various options for us since we live in a post-and-beam style home. The two installers were excellent, did quality work, and explained the unit's operation to me before they left. I'd use them again for my HVAC work.

They're my One and Only for HVAC and Plumbing. They were punctual, clean and removed all the old parts. Explanations of what was needed was layman-plain and NOT condescending. That's important to me. BEST PART - they don't give you an "estimate". They give you a price. And that comes with...
