Record Arizona Heat Leaves Valley Pools Facing Costly Repairs, Optimal Pool Care Says

Following Arizona's hottest summer on record, Scottsdale-based Optimal Pool Care reports a sharp increase in repair and cleanup requests since August. The primary culprits are failed pumps, algae-filled pools, and scaled or cracked surfaces. The heat arrived early and persisted: Phoenix hit 100 degrees as early as March 18, the earliest such reading in 20 years, and set a daily record of 114 degrees on August 25. Statewide, the summer averaged 2.7 degrees above normal temperatures.

"Most homeowners think of a pool as something that sits there all summer. In reality, the pump, filter and water chemistry were working overtime for six straight months. By October, a lot of that equipment is worn out, and the damage usually doesn't show until something fails," said Santos Castro, owner of Optimal Pool Care.

Technicians report that this summer's damage falls into three categories: overworked equipment, algae and unbalanced water, and surface and tile damage. Pumps operate longer hours to keep hot water circulating, causing motors to overheat, bearings to wear, and seals to fail. Sun and heat deplete chlorine faster than many homeowners replenish it, so a pool can turn green within days. Constant evaporation deposits calcium from the Valley's hard water, building scale on tile and plaster, while temperature fluctuations crack coping and loosen tile.

Optimal Pool Care recommends homeowners look for five warning signs this fall: a pump that sounds different (grinding, loud humming, or tripping the breaker); water that won't stay clear (cloudy or green water returning days after treatment); a white crust at the waterline; rough, stained or flaking plaster; and cracked coping or loose tile. These signs indicate worn motors, filter or circulation problems, calcium scale, or surface damage that may require an acid wash or resurfacing.

Fall is the time to address these issues before they escalate. Optimal Pool Care advises homeowners to have their pump, filter, water chemistry, and surfaces inspected this fall, before minor heat damage becomes a significant repair heading into next summer. The company provides weekly pool cleaning and full repair service across Scottsdale, Phoenix, Paradise Valley, Fountain Hills, Cave Creek, Tempe, Mesa, Gilbert, and Chandler, with written pricing provided upfront before any work begins.

"Weekly service is the best protection against a summer like this one. When someone checks your chemistry, cleans your filter and listens to your pump every week, small problems get fixed before they turn into a $1,000-plus pump replacement," Castro said.
