How Humidity Affects Your Cooling System

July 30, 2025

Humidity plays a significant role in how well your cooling system works. Beyond just making your home feel sticky and uncomfortable, high humidity forces your air conditioner to work harder, which can lead to inefficiency, discomfort, and potential maintenance headaches. For a proper breakdown on this issue, continue reading to hear what our Mick’s Plumbing & Heating team warns about and how to manage this problem. 

What Happens When Your Home Has Too Much Humidity

When the air in your home contains excessive moisture, your cooling system has to remove that moisture in addition to lowering the temperature. This dual task puts extra strain on the system, often reducing its efficiency. You might notice longer cooling cycles and higher energy bills as your AC tries to maintain a comfortable environment. Over time, this stress can wear down key components, increasing the likelihood of breakdowns. 

Additionally, high humidity levels can make it feel warmer inside, even when the thermostat is set at the desired temperature. This may lead to an urge to crank the AC lower, which only adds to the energy consumption and wear on your system. 

Tips to Manage Indoor Humidity 

Fortunately, there are several effective ways to control humidity and help your cooling system perform at its best: 

  1. Use a Dehumidifier – Installing a dehumidifier, either standalone or as part of your HVAC system, can significantly reduce moisture levels in the air. 
  2. Improve Ventilation – Ensure your home has adequate ventilation, especially in areas like bathrooms and kitchens where moisture tends to build up. 
  3. Seal Air Leaks – Gaps in windows and doors can allow humid air to enter your home. Properly sealing them can keep excess moisture out. 
  4. Schedule Regular HVAC Maintenance – Routine tune-ups can keep your system running efficiently, and technicians can identify any issues caused by high humidity levels before they worsen. 

By managing indoor humidity, you’ll enhance your family’s comfort and protect your cooling system from unnecessary wear and tear.
