Pool Equipment & Automation — What's Worth Spending On in Arizona

Why the equipment pad matters more than the tile

Homeowners obsess over finish color and tile patterns and barely look at the equipment pad. Mistake. Your pump, filter, heater, and automation determine your electric bill, your maintenance time, and how often you actually use the pool. AE specs Pentair across the board because the lineup integrates cleanly and the warranty support in Arizona is real.

Variable-speed pumps are non-negotiable

Single-speed pumps are now restricted in most cases, and for good reason — they burn 4–6× the electricity of a modern variable-speed pump. A Pentair IntelliFlo3 or similar VS pump pays itself back in 2–3 years on energy savings alone. Run it slow most of the day for filtration; ramp up only for cleaning or water features.

Filters — cartridge vs DE vs sand

Cartridge filters dominate Arizona installs. They filter finer than sand, use less water than DE, and the cartridges are easy to rinse out. DE filters are slightly finer but require periodic backwashing — wasteful in our climate. Sand is the cheapest but the coarsest. AE installs cartridge by default unless there's a specific reason to deviate.

Heaters — gas vs heat pump

Most Phoenix pools don't need a heater for summer, but a heater extends the season into March–May and October–November dramatically.

• Gas heater (natural gas or propane) — fast heat-up, higher operating cost, ideal for spas and on-demand heating.
• Heat pump — slower heat-up, much cheaper to run, ideal for keeping a pool warm continuously.
• Solar heating — viable in AZ but requires roof real estate and looks dated; rarely worth the trade-off on premium builds.

Salt vs chlorine — what we actually recommend

Salt systems (chlorine generators) produce chlorine from a low concentration of salt in the water. The water feels softer, smells less chemical, and you stop buying jugs of liquid chlorine. The cell needs replacement every 3–5 years (~$700–$1,200). For most AE clients, the comfort and convenience win — we install salt by default unless a specific finish or condition makes it a poor fit.

Automation — IntelliCenter changes everything

A Pentair IntelliCenter (or equivalent) gives you full control of pump speeds, heater, lights, water features, and spa from your phone. Schedule everything, get equipment alerts, fire up the spa from the highway on your way home. Add $2,500–$5,000 to the build and you'll never go back. This is the single best money spent on the equipment pad after the pump itself.

What it all costs to install

Numbers below are typical for a new build with quality Pentair equipment.

• VS pump installed — $1,800–$2,800.
• Cartridge filter installed — $900–$1,600.
• Gas heater (400K BTU) installed — $4,500–$6,500.
• Salt chlorine generator — $1,800–$2,800.
• IntelliCenter automation — $2,500–$5,000.
• LED color-changing pool light — $800–$1,400 each.
