"Terrible service and experience. AVOID. UNRELIABLE. SCAMMERS. They canceled on me at the last minute, then tried to cancel on me again a week later until I complained. Then someone shows up LATE and did a visual inspection to assess that my furnace is extremely old, everything is faulty or falling apart, likely can not be fixed because parts may not be available, recommends a entirely NEW furnace replacement. Since it is such a HUGE commitment, I declined. I called someone else, they came, fixed it ALL within 30min and said everything is working great. INCOMPETENT SCAMMERS!!"

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

"Bought a new house. They were the plumbing contractors. Their workmanship is horrible. We have low flow in the house as well as the outside spiket. Chuck, the owner has come out several times but without tools or to do anything! He always has a sob story as to why he can't do any work--not feeling well, employee hurt, employee stole his van/equipment etc. He stopped answering our calls and will not contact us. He just left us with a mess and the builder is not helping either. We have a house that Is valued at $700,000 that spits out water. The flow is so bad that you can't hook up an outside sprinkler to water the lawn or washing your car is like using a straw to rinse. I would not recommend this company for ANY plumbing needs. L and I also shows he has been fined in the past for using unlicensed employees for plumbing work."

Water treatment & purification system installations and replacements FAQs

In a reverse osmosis system, water from your main line—or from a designated faucet—is pushed through a semipermeable membrane under pressure. The membrane’s microscopic pores trap dissolved solids, heavy metals, and other contaminants, while clean water passes into a storage tank or straight to the tap. The leftover concentrated water simply drains away. The result is clear, great‑tasting water delivered right where you need it.

A plumber can set up a point‑of‑use unit in one to two hours. A whole‑house system is more involved and often takes one to two days because it ties into the main supply line and may need extra plumbing. During installation, the pro mounts the unit, connects the pipes, checks for leaks, and tests performance so you’re ready to pour a glass as soon as they leave.

Reverse osmosis removes dissolved solids, heavy metals, and many microorganisms, giving you water that tastes cleaner and protects your family. Softer water also helps appliances, faucets, and ice makers last longer. Because you’re filling reusable bottles instead of buying single‑use plastic, most homeowners save money and cut waste. In short, you get better‑tasting water, longer‑lasting appliances, and a smaller environmental footprint from one straightforward system.
