Hot Tub Care & Common Breakdowns in Arizona
In the arid, high-heat environment of Arizona, hot tubs face a unique set of challenges that are vastly different from colder climates. The relentless desert sun and ambient summer temperatures regularly exceeding 100°F create an environment that rapidly destroys the physical components of your spa if not properly maintained. The number one failure point we see in Arizona is severe UV damage to the acrylic shell, leading to blistering, spider-web cracking, and complete structural delamination.
Additionally, the extreme heat causes rapid water evaporation. When the water level drops below the skimmer intake, the circulation pump begins sucking in air (a condition known as cavitation). Because the pump relies on water to cool its internal motor bearings, running dry for even a few hours will cause the motor to overheat, seize up, and burn out completely. Our local Arizona technicians frequently replace burnt-out pump motors and melted heater relays caused by low water levels.
Finally, managing water chemistry in the desert is notoriously difficult. High evaporation rates leave behind concentrated levels of calcium and scale (Total Dissolved Solids). If you do not drain and refill your tub frequently, this calcium concrete will completely coat the inside of your titanium heater element, causing it to short out and trip your GFCI breaker. Regular professional maintenance is essential in this harsh climate.
