We contacted Cold is on the Right today with an urgent plumbing need. Their very professional and organized crew arrived within 30 minutes and fixed our issue. We called five other plumbing companies before them and no one was able to help us. Cold is on the Right will now be the first plumbers we call.

Services: Drain cleaning

We called due to slow drainage and apparently main line backing up into master bathroom shower and sink. There is an automated line that takes your information and apparently works very well. Plumbers Billy and Jeremy showed up promptly after we were informed they were being dispatched this morning, they stayed and worked until the problem was solved and advised on possible future repairs that would need to be done. They were professional, smart, respectful of our home, and efficient in their actions. Let us know what things would cost and were honest in their assessment of what would be needed next and how (un) likely our homeowners insurance would be able to help.  I appreciate the service and the fair treatment by these gentlemen. Thank you.

Santiago and Kyle were amazing during our total HVAC system replacement. Kind, informative, knowledgeable and careful to ensure a smooth install. They were efficient and got my AC working before my family arrived for spring break. Now enjoying the cool air with family. Great pricing and quick turn around from quote to finished job. Thank you! 10/10 would recommend them to anyone needing HVCA or plumbing work.

These guys are prompt and very polite, and explain your options well without trying to upsell. We thought we needed three things replaced, but they showed us that one of the three just needed an adjustment rather than a replacement. Wonderful service!

Frequently Asked Questions About Water Treatment Systems

Do Austin homes really need water treatment systems?

Many Austin homes can benefit from a water treatment system. Even with municipal water supplied through Austin’s treatment infrastructure, homeowners may still notice hard water, mineral buildup, chlorine taste, smelly water, cloudy water, or residue on fixtures and appliances. A properly selected water treatment system can address these issues at the home level, improving water quality for drinking, cooking, bathing, laundry, and everyday use.

What signs mean I may need a water treatment system?

You may benefit from a water treatment system if you notice white buildup on faucets, cloudy glassware, dry-feeling skin, stiff laundry, unpleasant water taste, chlorine odor, rotten egg smell, sediment, staining, or scale buildup around fixtures. These signs may point to hard water, minerals, sediment, chlorine, or other water quality concerns.

What’s the benefit of a reverse osmosis system?

A reverse osmosis system can provide cleaner, better-tasting drinking water by reducing many dissolved solids, minerals, and other contaminants. These systems are commonly installed at a kitchen sink or dedicated drinking water tap to improve the water used for drinking, cooking, coffee, ice, and food preparation. If your main concern is drinking water quality, reverse osmosis may be a strong option.

What does a reverse osmosis system remove?

Reverse osmosis systems are designed to reduce many common water concerns, including dissolved solids, sediment, chlorine taste, certain metals, and other impurities, depending on the system and filter stages. The exact performance depends on your water conditions and the equipment installed. Cold is on the Right can help you determine whether reverse osmosis is the right fit based on your goals.

Are your water treatment services cost-effective for homeowners?

Water treatment can be a smart long-term investment because it helps protect plumbing fixtures, water heaters, dishwashers, washing machines, coffee makers, ice makers, and other water-using appliances from mineral buildup and poor water quality. By reducing scale, improving water performance, and helping equipment last longer, the right system may reduce unnecessary wear and future repair needs.

Do you provide water treatment services for businesses as well as homes?

Cold is on the Right provides residential and commercial water treatment solutions throughout the Austin area. We help homeowners, restaurants, offices, retail spaces, and other businesses improve water quality, protect equipment, and support safer, more efficient water systems.

How quickly can I schedule water treatment service?

Scheduling water treatment service is simple. Our team will help you find an appointment, discuss your water concerns, and walk you through the next steps. From the first conversation to system selection and installation, we focus on clear communication, transparent recommendations, and a process built around your home or business.

What types of water treatment systems do you install?

We install and service water softeners, whole-home filtration systems, water conditioners, reverse osmosis systems, and other water treatment solutions depending on your needs. The right system depends on your water quality, household size, plumbing setup, and whether your main concern is hard water, taste, odor, sediment, or drinking water quality.

What is the difference between water filtration and water softening?

Water filtration focuses on reducing unwanted particles, chemicals, odors, tastes, sediment, and certain contaminants from the water. Water softening focuses on reducing hardness minerals like calcium and magnesium that cause scale buildup. Some homes need one system, while others benefit from both filtration and softening.

Is a whole-home water treatment system better than a sink filter?

A sink filter only treats water at one location, usually the kitchen faucet. A whole-home water treatment system treats water as it enters the house, helping improve water quality at showers, sinks, laundry areas, water heaters, and appliances. If your concern is only drinking water, a point-of-use filter may be enough. If the issue affects the entire home, a whole-home system is usually the better option.

Can water treatment help with hard water stains?

A water softener can help reduce the minerals that cause hard water stains, white residue, cloudy glassware, and scale buildup around faucets and showerheads. While it will not remove existing buildup on its own, it can help prevent new mineral deposits from forming as quickly.

Can water treatment improve the taste of tap water?

The right filtration system can improve tap water taste by reducing chlorine, sediment, odors, and other unwanted elements. If your water tastes metallic, earthy, chemical-like, or unpleasant, testing can help determine which system will best address the issue.

Why does my water smell bad?

Bad-smelling water can come from several sources, including chlorine, sulfur, bacteria, water heater issues, or plumbing system conditions. A rotten egg smell, musty odor, or strong chemical smell should be evaluated so the right treatment solution can be recommended.

Can water treatment help protect my water heater?

Hard water can cause mineral buildup inside the tank and tankless water heaters, reducing efficiency and increasing wear over time. A water softener or filtration system can help protect the water heater by improving the quality of water entering the system. This can support better performance and a longer system lifespan.

Can water treatment help with dry skin or hair?

Hard water can leave mineral residue on skin and hair, which may make them feel dry, rough, or harder to rinse clean. A water softener can improve how water feels during showers and help soap and shampoo lather more effectively. While it is not a medical treatment, many homeowners notice improved comfort after softening their water.

Do water treatment systems require maintenance?

Most water treatment systems need some level of maintenance. Water softeners may require salt refills and periodic inspection, while filtration and reverse osmosis systems need filter changes on a recommended schedule. Routine maintenance helps keep the system working properly and protects water quality over time.

How often do filters need to be replaced?

Filter replacement depends on the type of system, water usage, water quality, and manufacturer recommendations. Some filters need more frequent replacement, while others last longer. Our team can explain your system’s maintenance schedule and help keep it operating correctly.

How long does installation take?

Installation time depends on the type of water treatment system, the location of the equipment, and the plumbing work required. Many residential installations can be completed efficiently, but more complex systems or commercial projects may take longer. Before work begins, we will explain the installation process and what to expect.

How do I know which water treatment system is right for my home?

The best system depends on your water quality concerns, water test results, household usage, budget, and plumbing setup. Cold is on the Right will help you compare options and recommend a solution based on your home’s actual needs instead of using a one-size-fits-all approach.

Can you test my water before recommending a system?

Water testing is an important first step when you are not sure what is affecting your water. Testing can help identify hardness, sediment, taste and odor issues, and other concerns that guide the system recommendation. This helps ensure the treatment solution matches the problem.

Do you service existing water treatment systems?

Cold is on the Right can inspect, maintain, and service many existing water softeners, filtration systems, and reverse osmosis systems. If your system is leaking, not improving water quality, using too much salt, losing pressure, or overdue for filter changes, our team can evaluate it and recommend the next step.

Can water treatment improve water pressure?

Water treatment is not designed primarily to increase water pressure, but it can help when mineral buildup or clogged filters are contributing to flow issues. If your home has low water pressure, our plumbers can inspect the system to determine whether the cause is related to the treatment equipment, plumbing lines, fixtures, or another issue. In larger municipal systems, pump stations and reservoirs help maintain water pressure, but low pressure inside a home may still come from scale, clogged filters, or plumbing issues.

Are water treatment systems safe for the whole family?

A properly installed and maintained water treatment system can improve water quality for the whole household. The best system depends on your water concerns, especially if you want better drinking water, softer bathing water, or added protection for appliances and plumbing. Our team can help you choose a system that supports your family’s needs. Austin also uses reclaimed water in a separate purple pipe system for non-potable uses such as irrigation and toilet flushing, and reclaimed water is less expensive to treat than potable water.

Do you offer water treatment for commercial properties?

Commercial water treatment can help protect equipment, improve water quality, and reduce mineral buildup in businesses that rely on consistent water performance. We provide solutions for restaurants, offices, retail spaces, property managers, and other businesses throughout the Austin area.

What areas do you serve for water treatment services?

Cold is on the Right provides water treatment services in Austin and surrounding communities, including Bee Cave, Cedar Park, Dripping Springs, Georgetown, Lakeway, Leander, Pflugerville, Round Rock, Spicewood, Steiner Ranch, Westlake, and nearby areas.

Why choose Cold is on the Right for water treatment services?

Austin homeowners and businesses choose Cold is on the Right because we provide honest recommendations, licensed plumbing work, clear communication, and water treatment solutions designed around real water quality concerns. Our team helps you understand your options and installs systems with long-term performance in mind.
