Air Conditioning, Pools, and Plumbing: Seasonal Tips for Tropical Properties
Owning a villa in Koh Samui means having a slice of paradise — but paradise comes with its own set of challenges when it comes to property maintenance. The island’s tropical climate, with its mix of intense heat, high humidity, and heavy rain, can take a toll on your air conditioning units, swimming pools, and plumbing systems if not properly managed throughout the year.
At Inter Property Koh Samui, we help villa owners protect their investment with proactive, seasonal care. In this guide, we’ll walk you through essential maintenance tips — broken down by season — to keep your home running smoothly and your guests comfortable year-round.
Dry Season (December – April)
Peak tourism and perfect weather — but high usage of utilities.
1. Air Conditioning: Keep It Cool & Efficient
During the dry season, guests rely heavily on air conditioning. To avoid breakdowns or high energy bills:
- Clean filters monthly (or after each guest stay).
- Check for refrigerant leaks and ensure gas levels are stable.
- Service compressors and fans to prevent mid-season failures.
- Keep units shaded from direct sunlight for better efficiency.
✅ Pro Tip: Schedule a full air-con servicing at the start of high season to avoid costly emergency repairs later.

2. Swimming Pool: Daily Use = Daily Checks
Your pool is a highlight for guests — but also a magnet for maintenance issues if neglected.
- Check chlorine and pH levels every 1–2 days during heavy use.
- Clean leaves, bugs, and sunscreen oil from the surface and skimmer.
- Backwash the filter weekly to prevent algae buildup.
- Inspect pool tiles and grout for cracks or erosion.
✅ Pro Tip: Install a pool cover to reduce debris and chemical evaporation during downtime.
3. Plumbing: Watch for High Water Demand
With more guests comes more water usage. This can expose weak points in your plumbing system.
- Inspect all visible pipes for leaks or corrosion.
- Ensure water heaters are descaled — especially in areas with hard water.
- Clean shower drains to prevent clogs caused by sand, hair, and soap residue.
- Test water pressure to detect silent pipe leaks.
✅ Pro Tip: Install strainers in shower and sink drains to catch debris before it becomes a bigger problem.
Rainy Season (May – October)
Higher humidity, fewer guests, and a great time for preventive care.
1. Air Conditioning: Moisture Control is Key
Even if your villa is empty, don’t let it sit sealed in the humidity.
- Run AC units weekly to prevent mold buildup.
- Use dry mode or dehumidifiers to maintain air quality.
- Check for mold in and around vents and ceiling insulation.
✅ Pro Tip: Add silica gel packs in wardrobes and cabinets to keep moisture away from clothes and linens.
2. Swimming Pool: Algae-Proof Your Water
With fewer swimmers but more rain, your pool becomes prone to green water.
- Shock the pool regularly to kill bacteria and algae spores.
- Ensure drainage systems around the pool are clear to avoid flooding.
- Check for tile damage caused by expanding rainwater or storm debris.
✅ Pro Tip: Install a rain overflow system to maintain water balance during heavy storms.
3. Plumbing: Prepare for Storms
Rainy season means your drainage systems will be tested.
- Clean roof gutters and downspouts monthly.
- Flush outdoor drains to prevent pooling around foundations.
- Seal any pipe joints or entry points to avoid leaks from stormwater intrusion.
✅ Pro Tip: Invest in a sump pump if your villa sits on a slope or flood-prone area.
Transition Months (November & April)
Perfect time for inspections, upgrades, and preventive maintenance.
- Schedule deep cleaning and servicing for all AC units.
- Drain and refill the pool if water has turned or chemicals are imbalanced.
- Conduct a full plumbing check — including water pumps and septic systems.
- Review your maintenance records and schedule necessary upgrades before peak season hits.
✅ Pro Tip: Let your property management team perform a full seasonal audit so nothing slips through the cracks.
