Hard water is a common problem across Mesa and the East Valley. If you’re noticing scale buildup, dry skin, cloudy dishes, or appliances that don’t last as long as they should, a professionally installed water softener can make a big difference. Rusty’s Air Conditioning and Heating offers high-quality water softener systems designed to handle Arizona’s extremely hard water while improving the comfort and efficiency of your home.


Water Softener Installation

Hard water is one of the most common plumbing concerns for homeowners in Mesa and throughout the Phoenix area. Minerals like calcium and magnesium build up inside pipes, appliances, fixtures, and water heaters over time, creating scale that reduces efficiency and shortens equipment lifespan.

A professionally installed water softener removes these minerals before they circulate through your home’s plumbing system. By softening the water at the point where it enters your home, you can reduce scale buildup, improve water quality, and protect your plumbing and appliances.

Rusty’s installs high-performance water softener systems designed specifically for Arizona’s extremely hard water. These systems use advanced resin technology and smart control valves that regenerate only when necessary, helping reduce salt and water usage while maintaining consistent performance.

Benefits of installing a water softener include:

  • Softer skin and hair after bathing
  • Cleaner dishes and glassware
  • Reduced scale buildup on fixtures and plumbing
  • Longer lifespan for water heaters and appliances
  • Reduced soap and detergent usage

Water Softener Systems Starting at $1,549. Annual service starts at $150.

Whole-Home Water Treatment Systems

For homeowners looking for more comprehensive water treatment, Rusty’s offers advanced whole-home systems that combine filtration and water softening in a single solution.

These systems help reduce chlorine, heavy metals, and other contaminants while addressing hard-water minerals that cause scale buildup. The result is cleaner, better-quality water throughout your entire home, from your showers and laundry to your kitchen sink.

Our Green Fusion whole-home treatment systems use advanced filtration media and efficient resin technology to deliver powerful water treatment while using significantly less salt and water than conventional systems.

These systems are an excellent option for households that want improved water quality for bathing, cleaning, and cooking while still protecting plumbing and appliances from mineral buildup.

Whole-Home Treatment Systems Starting at $2,275. Annual service starts at $150.

Reverse Osmosis Drinking Water Systems

While whole-home systems improve water quality throughout the house, reverse osmosis (RO) systems provide highly purified drinking water directly at your kitchen sink.

RO systems use multiple stages of filtration to remove sediment, chemicals, dissolved solids, and many contaminants that affect taste and water quality. The purified water is stored in a small tank and delivered through a dedicated faucet whenever you need it.

  • Ulima RO systems: Many systems also include remineralization filters that replenish beneficial minerals, help balance pH levels, and improve taste, creating clean, refreshing drinking water.
  • Alkalizer RO: Reverse osmosis systems are ideal for drinking water, cooking, coffee, ice, and other household uses where clean, great-tasting water matters most.

Reverse Osmosis Systems Starting at $755. Annual service starts at $180.

UV Water Treatment Systems

UV water treatment systems provide an additional layer of protection by neutralizing bacteria, viruses, and other microorganisms that may be present in your home’s water supply. These systems use ultraviolet light to disinfect water without the use of chemicals, making them a safe and effective option for improving water quality.

UV treatment is often paired with other water treatment systems such as water softeners, filtration systems, or reverse osmosis units to create a comprehensive water purification solution. This ensures your household water is not only softened and filtered but also protected from microbial contaminants.

UV Water Treatment Systems Starting at $1,305.

Salt Monitoring and Delivery Services

Water softeners rely on salt to remove hard water minerals, but regularly checking and refilling the salt tank can be easy to overlook. Rusty’s offers convenient salt monitoring and delivery services to ensure your system always has the salt it needs to operate efficiently.

Our team monitors your system and delivers salt directly to your home, helping maintain optimal softener performance while eliminating the hassle of purchasing and hauling heavy salt bags yourself. Regular salt maintenance also helps extend the life of your system and ensures your home continues to receive properly softened water.

Salt Monitoring & Delivery Starting at $40 per month.


If you’re tired of dealing with hard water in your Mesa home, Rusty’s Air Conditioning And Heating can evaluate your water quality and recommend the right solution, from water softeners to whole-home filtration and reverse osmosis systems, with expert installation and maintenance to keep your system performing reliably for years to come.
