Water Softener Installation Services in Delaware

First Class HVAC is Delaware’s Water Treatment Specialist

First Class HVAC delivers specialized water treatment services for homeowners throughout Delaware and Maryland. Hard water can result in numerous consequences for you and your family. In addition to being potentially unhealthy to drink, it can cause dry or irritated skin, brittle or dull hair, mineral buildup in your plumbing fixtures, and spots on your glassware, among other inconveniences. But our team of specialists can install reverse osmosis systems, water softeners, and various other treatments in your home to minimize these issues. We can help you understand the risk you are taking by allowing hard water to remain a constant in your home, test your water, and provide a solution. Contact us today for your water test in Delaware or Maryland.

We Provide Free Water Tests for Delaware Homeowners

Water is essential to your everyday life. Not only do you drink it, but you use it to bathe, wash clothes and dishes, and cook. As such a critical element to your livelihood, you should ensure that it is safe and clean. First Class HVAC provides free in-home water tests for bacteria, lead, pesticides, nitrites and nitrates, chlorine, hardness, and pH. There are numerous signs and symptoms that will alert you to water contamination or hardness in your home. Contact us today if you notice:

  • Smells – The surest sign that you need to test your water is an unusual smell. Scents can vary from manure to metallic but must be treated immediately.
  • Odd Flavors – If your water tastes metallic or salty, there is likely an issue. Refrain from drinking it until First Class HVAC can test and treat it for your protection.
  • Flakes or Colors – A quick eye test will help you spot reasons for concern. If the water streaming from your sink has color or flakes, call us right away.
  • Dry Skin – Water hardness can cause dry hair and skin, or even rashes.
  • Stained Clothes – If you notice stains in your clothes following a wash cycle, your water may be to blame.

First Class HVAC Performs Water Softener Installation

Hard water can take a toll on your body, glassware, and fabrics. It produces an array of unwanted consequences, including scale buildup on appliances, clogged pipes, dry skin and hair, and foul odors. But it does not have to be the norm in your Delaware home. First Class HVAC provides water softener installation to minimize the effects of hard water in your system and pipes. A water softener will remove calcium, magnesium, and other minerals before they enter your water heater or home and have a chance to combine to form scum and buildup. If you notice problems associated with hard water, call us immediately. We will test your water to determine how many grains of hardness it contains. Using that knowledge, along with an understanding of how much water you use, we will install a water softener that works best for you.

Reverse Osmosis Water Installation Through First Class HVAC

The team at First Class HVAC is skilled at treating water using reverse osmosis (RO). This technique decreases dissolved or suspended contaminants in your home’s water by applying pressure to push the brine through a semipermeable membrane. The membrane blocks contaminants, only allowing clean water to flow through to the less concentrated side. We perform RO water installations for homeowners in Delaware and Maryland to help ensure everyone has safe drinking water. Installing a reverse osmosis system promises the removal of:

  • Fluoride
  • Salt
  • Minerals
  • Sediment
  • Chlorine
  • Arsenic
  • Volatile organic compounds (VOC)
  • Herbicides
  • Pesticides
  • Dissolved solids

We Offer UV Water Treatment in Delaware and Maryland

Another service we offer at First Class HVAC is UV water treatment. The process involves using ultraviolet radiation to alter the DNA of microorganisms so that they cannot spread disease or infect the water supply. However, UV water purification does not remove contaminants. A UV water purifier will deactivate:

  • Cryptosporidium
  • Giardia
  • Dysentery bacilli
  • Salmonella
  • Mycobacterium tuberculosis
  • Streptococcus
  • coli
  • Hepatitis B
  • Cholera
  • Algae
  • Fungi
  • Some viruses
