Is your air conditioner sweating? Don't sweat it!

April 22, 2024

Here's a cool breakdown of what might be going on:

What could be causing my A/C to sweat?

Temp Setting Too Low:

It might be tempting to crank down your A/C in humid weather, however, this can cause excessive condensation. 

In humid conditions we recommend a temperature set point of around 22-23°C Degrees on cooling; anything lower than that, particularly in really humid conditions, runs the very real risk of water droplets forming.


Keep tabs on the humidity: 

As mentioned, if humidity is high, we suggest you stick to around 22-23°C temp setting on cooling.

Going lower, especially below 20°C, increases the risk of water droplets forming on your split A/C unit, or moisture forming around ducted A/C outlets. During extreme weather it can be tempting to run your AC 24/7 at low temps.

However, this is a recipe for condensation city for any air conditioner!


Other Causes of AC Sweating:

Humid Air getting in:

Living in a humid spot? Sneaky gaps in your room could be letting in hot humid outside air, causing condensation. Keep doors and windows shut, and/or seal 'em up as best you can.


Restricted Airflow:

Blocked ducts, filters, or frosty coils can cramp airflow, leading to sweating. A good first step is to check that the A/C's filter is clean. If it's not the filter, it might be time to call in a technician to get things flowing smoothly again!


Insulation:

On ducted systems don't let your ducts get too chilly! Make sure they're snug with the right insulation to fend off condensation.

Mackies use R1.2 insulation which is thicker, and performs better than standard R1.0 insulation.

 

Plugged Drain Line:

Uh-oh, a clogged drain line? That's trouble brewing. This is something that can happen over time. If you spy drips on your split system or near vents on your ducted system, and you have ruled out everything else, it's a sign to dial up a technician to dodge potential disasters!
