You unlock the door, step inside your Coachella Valley home, and instantly notice it — that stale, musty smell that clings to the air.
It’s more than unpleasant; it’s a warning.
Even in the dry desert, mold and mildew can thrive under the right conditions — and when a home sits empty for weeks or months, those conditions are easier to create than you might think.
Here’s how to prevent mold while away and protect your home from humidity, odors, and long-term damage.
1. Keep Air Circulating
Still air is the enemy.
When your HVAC system stays off for too long, humidity and condensation can collect in corners, closets, and behind furniture.
Before you leave, set your thermostat to around 78–82°F and make sure your system cycles regularly.
If you have ceiling fans, set them to rotate counterclockwise at low speed to keep air moving gently throughout your home.
Better yet, ask a Home Watch professional to check your HVAC filters and run the system during each visit.
2. Don’t Seal the House Too Tight
It’s tempting to close everything up tight before leaving, but trapped air becomes stale fast.
Crack an interior door here and there, leave closet doors ajar, and avoid wrapping towels or linens in plastic. Breathable materials prevent moisture from getting trapped — and that means fewer odors later.
A Coachella Valley humidity home can fluctuate from bone-dry to muggy overnight after a rare desert rain, so allowing minimal airflow makes a surprising difference.
3. Control Humidity — Even in the Desert
Yes, the desert is dry, but indoor humidity can rise from plumbing leaks, irrigation overspray, or even condensation from air conditioning.
To stay safe, use desiccant dehumidifiers or moisture-absorbing crystals in closets and bathrooms.
Home Watch professionals also check humidity levels during routine inspections — and they’ll spot early signs of excess moisture before you ever smell it.
4. Shut Off Water — but Drain and Seal Properly
If you’re leaving for more than a few weeks, shut off the main water supply and drain your lines. This prevents slow leaks and stagnant water, both of which invite mold growth.
Home Watch services often include flushing toilets and running faucets during visits to keep seals from drying out and prevent sewer gas from entering the home — another common source of that “musty” smell.
5. Have Regular Home Watch Visits
Even with all the right precautions, things can still go wrong — a leaking roof after a storm, a failed AC sensor, or an unnoticed window left open.
That’s why having a professional Home Watch team is the single best protection against mold and mildew while you’re away.
During every visit, your Home Watch professional checks:
- HVAC settings and humidity levels
- Plumbing lines and visible pipes
- Ceiling corners, closets, and attics for moisture signs
- Odors or air quality changes
They’ll document any concerns immediately and coordinate repairs if needed — so small issues never turn into big ones.
Protect Your Desert Home from the Hidden Cost of Still Air
Mold and mildew don’t just affect air quality — they can damage drywall, furniture, and even your health.
By keeping air moving, managing humidity, and scheduling regular inspections, you’ll return to a home that smells fresh, feels clean, and welcomes you back exactly as you left it.

FAQ: Preventing Mold in a Desert Home
Q: Can mold really grow in a dry climate like the Coachella Valley?
A: Yes. Indoor humidity from plumbing, AC condensation, or leaks can create micro-climates perfect for mold — even in a dry region.
Q: How often should my home be checked for moisture or humidity?
A: Bi-weekly visits during the summer are ideal. That’s when heat and humidity fluctuations are highest.
Q: What’s the ideal indoor humidity level for preventing mold?
A: Keep it between 30% and 50%. Your Home Watch professional can monitor this during inspections.
Q: Will running the AC help?
A: Absolutely. Running the system regularly keeps air moving and humidity balanced — especially when filters and drains are maintained.
