“NEXTGEN repaired my HVAC system which had an intermittent heating problem on a timely basis and it was covered under warranty. The technician was very polite an professional.”- Mark R.

“Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”- Carly N.

“My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”- Andrew W.

“Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”- Erika A.

“My thermostat took a dive on me so I went to replace it. That's where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don't use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that's when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he's doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I'm at. Can't say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you'll find value.”- S.S.

“My AC stopped working and gave me a power failure message. Ryan was dispatched as the technician to assist. He was great, he quickly diagnosed the issues (fuses and capacitors). He gave me practical solutions and was great to work with. If I have issues in the future I will be asking for him specifically.”- Roger D.
Water Filtration System Installation in Southern California
Utility water is filled with many impurities. However, not every water filtration system is the same, and you can’t rely on traditional municipal water treatment methods for protection. Hard water corrosion can reduce the performance and life expectancy of your plumbing, while chlorination by-products have serious health risks. Our inline and whole-house water filtration systems provide direct physical treatment to ensure your water supply is safe.
Benefits of Water Filtration Systems
A water filtration and conditioning system avoids the need for water softeners, which often rely on salt. However, softeners don’t improve water quality and self-regenerating varieties contribute to environmental pollution. Carbon-based filtering avoids these problems and improves water quality. It removes chlorine, dyes and other commercial additives, and other contaminants including:
- Disinfectants such as bleach, calcium hypochlorite, and chlorophenol
- PCB-based insecticides, herbicides, and pesticides
- Glycols, Benzene, dissolved oil, chloroform, and other solvents
- Iodine, isopropyl alcohol, and other pharmaceutical by-products
- Tannins, or food and wine by-products
Water filters also reduce contaminants such as detergents, hydrogen sulfide (produces a rotten egg or sulfur odor), and acetic acid, a by-product of water chlorination. They also reduce heavy metals such as lead, chromium, zinc, copper, and cadmium, as well as a variety of commercial additives and solvents, and, to some extent, iron.
With a water filtration system, that bad taste or bad smell can be eliminated. It can also improve your health; if water tastes better, it’s easier to drink more of it, which is good for your organs, joints, and overall health. You also save on buying bottled water, the cost of which can add up significantly in the long run. Cleaner water also helps appliances last longer which contributes to additional savings.
Common Problems & Typical Water Contaminants
Municipal water sources can contain various contaminants that cause problems, including:
- Additives: Chlorine or chloramines (ammonia added to chlorine) are often mixed with drinking water to disinfect it. Chloramine compounds can cause skin irritation and digestive disorders, while chlorine can corrode copper pipes and damage toilets, faucets, and rubber seals in plumbing.
- Hard Water: Calcium and magnesium particles in water can form mineral deposits within piping, storage tanks, and household plumbing components. They can damage appliances, coat dishes and glassware, and restrict or block water flow.
10-Year Warranty and Maintenance Free
All our water filtration and purification systems are protected by an outstanding 10-year warranty. Plus, receive an extended parts and labor warranty by joining our X Protection Plan. Our products are maintenance free for added convenience; never replace filters or media, while highly filtered alkaline water is available from every faucet in your home.
Whole-House Water Filtration System and Installation
A whole-house water treatment system is connected at the main line, rather than under the sink or to individual plumbing fixtures. Multi-stage hard water treatment allows for complete filtration and conditioning. Our filtration systems are maintenance free.
The ION water conditioner dissolves mineral scale and inhibits hard water corrosion. ION filters temporarily alter the charge of dissolved minerals such as calcium carbonate and magnesium carbonate. This prevents them from being attracted to and bonding to one another in plumbing systems due to temperature and pressure changes, friction, and turbulence. Reversing polarity magnetic fields form aragonite, a powdery physical state of suspension in which molecules flow through the plumbing system until they’re discharged or separated by filtration or centrifugal equipment.
Trust NEXGEN for Your Next Water System
NEXGEN is proud to provide installation services for water filtration equipment. A product line of premium water filtration and conditioning systems is available to prevent chlorine damage, mineral scaling, and contamination by bacteria and viruses. In addition to effective hard water control and less backwash, these systems come with a limited lifetime warranty (for up to 13” diameter mineral tanks in point-of-entry residential water filters/conditioners).
