When it comes to building durable, comfortable, and healthy spaces, managing moisture is non-negotiable. Yet, many projects overlook key questions during the HVAC design and installation phases—leading to costly callbacks, mold issues, and unhappy occupants down the line.
If you’re a builder, contractor, or project manager, you can safeguard your investment and reputation by asking your HVAC installer more than just the basics. Here’s a deeper dive into the critical questions that should be part of every moisture control conversation.
1️ How Will Humidity Be Managed Year-Round?
Your HVAC installer should have a clear plan for managing both latent (humidity) and sensible (temperature) loads. Ask:
- Are dehumidifiers integrated into the system?
- Is there a plan for shoulder seasons when the AC isn’t running?
- What RH levels are expected indoors?
2️ Is the HVAC System Sized for Both Cooling and Dehumidification?
Oversized or improperly balanced systems may cool the air quickly but fail to remove enough moisture, leading to clammy conditions. Confirm:
- Load calculations include moisture, not just temperature.
- Equipment selection factors in the specific climate zone.
3️ What Options Exist for Standalone or Supplemental Dehumidifiers?
Even the best HVAC systems may struggle in high-humidity environments. Ask about:
- In-wall, on-wall, or whole-house dehumidifier options.
- Retrofitting potential in existing buildings.
- Energy efficiency ratings and maintenance needs.
4️ How Will Ventilation Impact Moisture Levels?
Bringing in outdoor air can introduce additional humidity. Ensure:
- Ventilation systems are balanced and properly filtered.
- There’s a strategy to condition incoming air.
- Energy recovery ventilators (ERVs) are properly integrated.
5️ Are There Moisture Sensors or Controls Included?
Smart systems can monitor RH levels and adjust performance in real time. Explore:
- Humidistats and integrated controls.
- Alerts or reporting systems for facility managers.
6️ What Are the Maintenance and Service Requirements?
Reliability matters. Be clear on:
- Filter change intervals.
- Condensate management.
- Access for routine checks.
Why It Matters
Failing to address moisture proactively can lead to:
- Mold and mildew outbreaks.
- Structural damage.
- Reduced energy efficiency.
- Tenant/owner complaints and legal issues.
The Bottom Line
A robust moisture management plan is essential for building performance and occupant health. By asking these detailed questions upfront, builders can avoid pitfalls and deliver better-quality projects that stand the test of time.
