Now that summer’s in full swing, you may need to think about managing indoor humidity. If you’ve noticed condensation on your AC vents, that could signal a problem. We asked one of our GVEC experts, HVAC Installation Superintendent Fernando Maldonado, some questions about this issue. Here’s what he had to say:

What does it mean if I notice condensation on my vents?

Condensation on the vents can be caused by a few things, such as lack of insulated ductwork or possibly damaged ductwork. A poor connection from the grille vent to the register box (boot) or lack of insulation around the register box in the attic can also be the culprit. The problem is typically caused when warm/humid air comes into contact with the cold surface of the vent.

Why does indoor humidity matter for my HVAC system and cooling costs?

Warm air holds more moisture than cool air, so on days the outdoor temperature and humidity levels are high, your HVAC system works harder to remove moisture from the air. When your system runs longer or harder than it needs to, this can lead to higher energy bills and may even shorten the lifespan of equipment.

What should I do to decrease indoor humidity in my home?

There are a few things you can do or have checked with the help of the heating and cooling experts at GVEC. Ensure your HVAC system is properly sized for your home. This means making sure your unit is the correct tonnage based on square footage. Have your ductwork properly sealed and insulated to prevent moisture from entering the system from unconditioned spaces. Preventive maintenance is also critical—this includes having your system inspected prior to heading into the heating or cooling seasons to check that all major components, ductwork and drain lines are operating properly.
