Frequently Asked Questions

Frequently Asked Questions

At Jones Air & Water, we help homeowners and businesses across the St. Louis and St. Charles region solve water and air quality problems — from hard water and iron staining to reverse osmosis systems and whole-house air purification. Below you’ll find answers to common questions about water softeners, well water treatment, indoor air quality, and free water testing.

 

What areas do you serve?

We serve homeowners and businesses across the greater St. Louis region, including communities around St. Charles. If you’re not sure whether you’re within our service radius, contact us, and we’ll quickly confirm.

Do you offer free water testing, and what does it include?

Yes. We conduct an on-site water assessment and review the specific concerns you’re experiencing, such as spotting on dishes, unpleasant odors, staining, or dryness. Based on the test results, we provide clear recommendations tailored to your water quality, including a water softener, whole-house filtration, a reverse osmosis system, or specialized well water treatment.

How do I know if I have hard water?

Common signs include white scale on faucets, cloudy glassware, soap that won’t lather well, dry/itchy skin, dull laundry, and reduced water pressure from buildup. A quick test confirms hardness levels and helps determine the right solution.

What’s the difference between a water softener and a salt-free system?

A water softener removes hard water minerals (such as calcium and magnesium) to help prevent scale. Salt-free systems typically reduce scale buildup by conditioning the minerals rather than removing them. The best choice depends on your water chemistry and your goals.

Will a water softener make my water taste salty?

Most homeowners don’t notice a salty taste. Softening doesn’t add salt “into” your water the way people often assume — it exchanges hardness minerals as part of the process. If taste is a concern, we can recommend a setup that keeps drinking water tasting great (often with a dedicated filter or under-sink system).

Do you treat well water?

Yes. Well water can come with unique issues such as sediment, iron staining, sulfur (“rotten egg”) odor, discoloration, or other contaminants. We’ll test first, then recommend a treatment plan that matches your well water’s needs.

My water smells bad (like sulfur) and causes staining on sinks — how can you help?

Odors and staining are usually caused by specific substances (often iron, manganese, sulfur, or bacteria in well water). By first conducting accurate testing, we can identify the cause and recommend a filtration or treatment system that delivers results.

What is reverse osmosis (RO), and do I need it?

RO is an advanced filtration method, usually installed at the kitchen sink, to improve the quality of drinking and cooking water. It’s great for people who want cleaner-tasting water and extra filtration beyond a whole-house system. Whether you “need” it depends on your water results and preferences.

Do I need a whole-house filter, an under-sink filter, or both?

A whole-house system treats water for bathing, laundry, and every faucet. An under-sink system focuses on drinking/cooking water at one location. Many homes do both: whole-house for overall water quality + under-sink/RO for the best-tasting drinking water.

How long does installation take, and will I be without water all day?

Many installations can be completed in a single visit. There may be a brief period when water is shut off during the hookup, but we’ll walk you through what to expect and keep disruptions to a minimum.

How often do filters need to be replaced or serviced?

It depends on the type of system, your water quality, and household usage. We’ll give you a clear maintenance schedule and can provide ongoing service so you’re not stuck guessing when something needs attention.

Do you service or replace existing systems (even if you didn’t install them)?

In many cases, yes. If you already have equipment in place, we can inspect it, confirm it’s working properly, and recommend repair, maintenance, or replacement options as needed.

What brands or equipment do you offer?

We carry and install trusted brands such as A. O. Smith, Rinnai, Aprilaire, Ecosmarte, and Hydrotech. We’ll recommend the best-fit system based on your water test results and the problems you want to solve.

What can you do to improve indoor air quality in my home?

We offer solutions such as whole-home humidifiers, dehumidifiers, and air purification systems designed to enhance comfort and indoor air quality. If you’re dealing with dryness, excess humidity, odors, or allergens, we can recommend the right setup for your home.

How much do water softeners or filtration systems cost?

Pricing varies based on your water test results, the type of system, home size, and installation needs. The easiest way to get an accurate number is with a quick consultation and water test; then we’ll provide options at different levels so you can choose what fits your budget.

Can air purification help with allergies, dust, and odors in my home?

Yes. A properly matched air purification system can help reduce airborne particles such as dust, pollen, and other irritants, as well as common household odors. The best solution depends on what you’re trying to address (allergens, odors, pet-related issues, etc.), so we’ll recommend a setup that fits your home and your concerns.

Can high humidity in my home lead to mold or mildew problems?

Yes. Excess indoor humidity can create conditions where mold and mildew are more likely to grow, especially in areas like basements, bathrooms, and around HVAC systems. If your home feels damp, smells musty, or you notice condensation, a whole-house dehumidifier may help control moisture levels and improve comfort.

Why is indoor humidity control important in the St. Louis area?

St. Louis homes often deal with humid summers and dry winter air, which can affect comfort and indoor air quality. Too much humidity can lead to musty odors and mold/mildew risk, while dry air can cause irritation and static. A whole-home humidity solution helps keep indoor air more balanced year-round.
