Longmont Hot Tub Maintenance Checklist: Monthly, Seasonal & Year-Round Essentials

Owning a hot tub is one of the best investments you can make for your home and lifestyle. It’s your personal retreat—whether you’re unwinding after a long day, enjoying a weekend soak with friends, or creating a wellness ritual. But like any investment, it requires proper care.
At Mountain Mist Spa and Sauna in Longmont, we proudly carry trusted brands like Marquis, Nordic, Tropic Sea Spas, and Artesian Spas. While these brands are built for durability and performance, even the best spas need consistent upkeep to stay at their peak. That’s where a reliable maintenance routine comes in.
This checklist will guide you through the monthly, seasonal, and year-round maintenance essentials to keep your spa sparkling, efficient, and always ready for you.
Why a Maintenance Routine Matters
Regular hot tub care isn’t just about looks—it directly affects the spa’s performance, longevity, and safety. Without proper maintenance, water chemistry can shift, filters can clog, and components can wear out prematurely. On the other hand, a well-maintained hot tub provides:
- Healthier water, free from bacteria and buildup.
- A longer lifespan for pumps, heaters, and plumbing.
- Lower operating costs due to better efficiency.
- A superior user experience, with clean water, clear jets, and consistent performance.
Think of maintenance as protecting both your investment and your health.
Monthly Maintenance Checklist
A simple monthly routine helps you prevent small issues from becoming bigger (and more expensive) problems. Here’s what to do every few weeks:
- Test and Balance Water Chemistry: Use a reliable test strip or digital tester to check levels for pH (7.2–7.8), alkalinity (80–120 ppm), and your chosen sanitizer (chlorine, bromine, or alternative system levels). Balanced water not only feels better on your skin but also prevents corrosion or scale in your hot tub.
- Clean the Filter: Remove the filter and rinse it with a garden hose to get rid of trapped debris. For a deeper clean, soak it in a filter-cleaning solution once a month. A clean filter ensures steady water circulation and reduces strain on your spa’s pump.
- Inspect the Spa Cover: Check your cover for any tears, waterlogging, or mildew. Wipe it down with a gentle cleanser and apply a UV protectant to extend its life. Remember, your cover keeps heat in and debris out, so treating it well is important.
- Check Jets and Surfaces: Run the jets to ensure even pressure and inspect the spa shell for any cracks, discoloration, or scaling. Catching minor issues early can prevent major repairs down the road.
Seasonal Maintenance Checklist

Every few months (or seasonally, depending on how often you use it), it’s smart to take your hot tub care to the next level.
- Drain and Refill the Water: Most spa owners should completely drain and refill their hot tub every 3–4 months. Over time, dissolved solids from chemicals, body oils, and other contaminants build up in the water. Fresh water means cleaner soaks and easier maintenance.
- Deep Clean the Shell: While your hot tub is empty, use a non-abrasive spa cleaner to scrub the interior shell. Avoid using household cleaners—they can damage the surface and leave behind harmful residues.
- Flush the Plumbing: Use a line flush product to clean out any biofilm or buildup in your spa’s plumbing lines. This step is crucial for water quality and overall performance.
- Inspect Components: Check your heater, pump, and control system for any signs of wear. Tighten any loose fittings and make sure all systems are working properly before refilling the spa.
- Rotate Filters: Consider keeping two sets of filters—one in use and one being cleaned. Rotating them ensures your spa always has a fresh, effective filter in place.
Year-Round Spa Maintenance
Beyond your monthly and seasonal care, these year-round practices help your hot tub remain a dependable retreat for years to come.
- Monitor Water Levels: Due to evaporation and splash-out, your water level may drop. Always keep it above the jets to maintain proper circulation and prevent pump damage.
- Winter Prep (for Our Colorado Climate): If you’re a year-round soaker, make sure your spa is ready for our cold winters:
- Keep the water circulating to prevent freezing.
- Maintain proper cover insulation.
- Check for any drafts or exposed plumbing.
- If you won’t use your hot tub in the winter, consider a professional winterization service to safely drain and protect the system.
- Energy Efficiency: Always keep energy efficiency in mind:
- Use your spa’s economy or sleep mode when it’s not in use.
- Keep the cover securely fastened to hold heat in.
- Clean filters regularly to reduce strain on your system.
- Schedule Professional Checkups: Even if you are diligent with at-home maintenance, an annual inspection by a spa technician is a smart move. Our team at Mountain Mist Spa and Sauna can service Marquis, Nordic, Tropic Sea Spas, and Artesian Spas to make sure they’re running at their best.
A Quick Look at Common Mistakes to Avoid

- Ignoring cloudy or foamy water: This usually signals a chemical imbalance.
- Overusing chemicals: More is not always better.
- Forgetting to use the cover: Without it, dirt, leaves, and bugs can quickly contaminate the water.
- Skipping regular filter care: Clogged filters strain your pump and heater.
Avoid these common pitfalls, and your hot tub experience will be smoother and stress-free.
Caring for your hot tub may sound like a lot, but once you build a routine, it becomes second nature. Regular attention saves you money, protects your investment, and ensures your spa is always ready when you need it most.
