Commercial HVAC Maintenance: Are You Controlling Moisture in Your Building?

Think you have a moisture problem in your facility or office?

If you have a rain leak, it could be improper installation of siding, flashing, or your weatherstripping or caulking could have issues.

But if you have dust mites, mold spores, the air isn’t feeling as comfortable as it was prior to this season, you have visible signs of moisture (like on windows), wilted or foul-smelling plants, or you’ve even seen wallpaper start to peel or “bubble” in your buildings, you may have a moisture problem.

While every facility can have a number of things contributing to a moisture issue—and this list is by no means comprehensive—here are 3 things to consider for a moisture control strategy.

Make sure your system is the proper size

Oversized systems aren’t going to be as effective as properly sized and located systems. That’s one of the first things you want to check to be sure your AC is able to do its job: both controlling temperature and helping to control humidity.

Evaluate your ventilation

If you ask us to evaluate your current ventilation and air flow, we’ll look at the current moisture levels in your building, including an evaluation of your current ventilation design. From there, we can see the amount of humidity that needs to be removed from the indoor air in order to achieve optimal, healthy indoor humidity levels.

Proper ventilation design regulates humidity and fights back against improper air flow and air pollutants in general so that bacteria can’t thrive and so that humidity in your building stays at a safe level.

Just a few areas we may look at include:

  • overall system design and current effectiveness
  • proper and appropriate air flow in all parts of the building
  • distribution of air and opportunities to improve distribution of air
  • sufficient removal of pollutants
  • air cleaners’ effectiveness
  • proper exhaust opportunities
  • opportunities to increase natural ventilation
  • location of supply vents
  • process of dilution of indoor contaminants
  • how and when an HVAC is operated (such as when occupants are in the building or when a building has greatly increased number of occupants, etc.)

Consider a dehumidifier

Dehumidifiers help to control humidity by removing excess moisture from the air. Today’s choices of dehumidifiers for commercial buildings have extremely efficient refrigeration coils, compressors, and fans; some even use as much as 30 percent less energy that traditional models.

Ask us for more help on what’s right for your building based on our evaluation.

They aren’t always going to make a major difference, but there are a few other small changes you can make in your office or building. Examples include:

  • Utilize humidity-absorbent plants
  • Add signs to remind people to use exhaust fans where appropriate
  • Keep interior doors open (which increases ventilation but can other potential drawbacks)
  • Encourage occupants to always close doors as much as possible
  • Encourage occupants to keep windows shut, even on hottest days
  • Keep surface areas as dry as possible in the building
  • Run dishwashers or other major appliances during the night
  • Check to see if there are any leaky pipes or faucets and fix
