"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"My boiler was not working. I had a company come out and say that it was so old and carbonized the best bet was to replace it. I called other companies who either refused the work of attempting to fix and clean or suggested a full replacement. Upon recommendation of my realtor, I called Franco Belli Plumbing. I spoke with the manager there, Manny, who after seeing photos of my boiler, insisted he could fix the boiler. And fix it he did! Manny knows what he is doing, he's like a boiler artist, a Mozart of heating systems. He just gets it. My boiler is up and running perfectly, and judging from the way it looked on the inside before and after - is running even better than it was before. Such fair pricing as well, after a lot of researching and calling around - Manny did this amazing work and saved me from using another company and their easy way out of installing an entire new boiler at $5K when I could get another 10 years out of this one. Don't hesitate to call Franco Belli Plumbing & Heating! Manny is the best!"

"Antonio, at Greenovative, was great. I really enjoyed his professionalism. He and his crew found creative ways to decrease the price of the project. We are happy we gave Greenovative this project. Honestly, we will use them again."

Water Softeners FAQs, answered by experts

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.
