Nick's reviews. Unedited.
Real Google and Yelp reviews of Nick's company. Nothing edited.
My water heater wasn't working correctly and Nick was recommended to us. He came in for an inspection and explained everything very well that was wrong. They took out and installed a new water heater. We didn't have to worry about anything. Him and his coworkers; Evan and Alex were a pleasure to work with.
We had an excellent experience with Central Valley. Nick was responsive and helpful. His quote was less than half what a competitor quoted! Evan came to the house prepared for a replacement but was actually able to fix the problem within just a few minutes. I will definitely call again with any future needs. We highly recommend this company!
Nick came out and explained things very well. His crews came out and did the roof and dry wall repair. Very professional, on time and they cleaned up all the debris. Gave me a quote which was less than the other companies. They are also available on the weekends, which is a huge plus since I work. When you have questions and you texted Nick, he was very responsive. Overall, I'm very pleased with the service. Definitely recommend them, you won't be disappointed for sure.
This is what Fresno water leaves behind.
Fresno tap water runs 5–11 grains hard. Here's what that looks like.

Water softeners, filtration and reverse osmosis in Fresno, CA
Fresno Water Pros is the water systems division of Central Valley Home Upgrades, the company Nick Alvarado has run in Fresno since 2010. We install water softeners, whole-house water filtration and reverse osmosis drinking water systems across Fresno, Clovis, Madera, Sanger, Selma, Reedley, Fowler, Kerman and Kingsburg — and we service and repair existing RO systems of most brands.
Fresno pulls most of its water from groundwater wells blended with river water, and the city's own 2024 water quality report lists hardness from about 4 to 11 grains per gallon depending on which wells feed your street. Clovis reports readings even higher. That hardness is what leaves white scale on faucets, spots on glasses and buildup inside your water heater. Chlorine used to disinfect city water is what gives tap water its pool taste. See the real numbers →
Every job starts with a free in-home water test. Nick measures hardness, TDS, chlorine and pH at your kitchen sink, shows you the results, and writes you a price for the system your water actually needs — a softener, a carbon filter, reverse osmosis at the sink, or a combination. On a county well? See well water treatment. Wondering about price? Read what a water softener costs in Fresno or salt vs. salt-free.
Straight answers before you call.
Is the water test really free?
Yes. Nick tests your tap water at your kitchen sink, shows you the results on the spot and leaves you a written price. It takes about 20 minutes and you are not obligated to buy anything.
What is the September Special?
Text a photo of your water — a glass from the tap, the shower head, the crust on a faucet — to (559) 795-4083, and Nick locks in the best pricing available in the Valley for you on a complete whole-home system, a softener or a reverse osmosis drinking water system, installed. You can also just call; he gives you the number on the phone or in writing at the free test, no pressure either way.
Is Fresno and Clovis water actually hard?
It depends on which wells feed your street. The City of Fresno's own 2024 water quality report lists hardness from 65 to 190 mg/L — that is roughly 4 to 11 grains per gallon, from 'moderately hard' to 'very hard' on the USGS scale. Clovis reports a range up to 290 mg/L (about 17 grains). The free test tells you exactly where your house sits. See the real numbers →
Can I get just reverse osmosis drinking water, or just a softener?
Yes. Reverse osmosis drinking water and under-sink filters can be installed on their own, or bundled with a whole-house system. We size it to what your water needs, not to a package.
Do you service reverse osmosis systems you didn't install?
Yes — most brands. Filter and membrane changes, slow flow, leaks, bad taste. Nick will give you a straight answer on whether it's worth fixing or time to replace.
How long does installation take?
Most whole-home systems are installed in about a day. Reverse osmosis and under-sink systems take a couple of hours. Usually we can schedule within the week.
What warranty do I get?
A 100% satisfaction guarantee on the installation itself, plus the manufacturer's warranty on every system. Nick walks you through the exact terms in writing before anything is installed.
Do you work on well water?
Yes. Wells around Madera, Sanger, Kerman and the county often carry iron, sediment and nitrate that city water doesn't. We test the well first and build the treatment around what's actually in it.
