I’ve been a King customer thru furnace and air conditioner install and the regular maintenance that keeps everything running smoothly. It was time for a new water heater and gave my business back to King. I went with a tankless system. Able was the project lead plumber. He walked me thru each step, answered all my questions and listened to my ideas for tweaking the location. The team of four worked as one and the project was finished sooner than I expected. Top shelf! Thanks King and the King guys.

The Frankfort team (Jeff, Ritchie and Brandon) were awesome and represented the KING brand well in their performance! They were professional, attentive, knowledgeable and explained steps that needed to be done in the work process for a quality HVAC and Furnace replacement. These guys worked in the rain and got the job done ✔️ THANK YOU!!!

Technician Ken was absolutely outstanding!! Beyond professional and very fun to talk with. He immediately found the problem and fixed it. I do have to apologize to him for my grandson screaming like a fool lol. He has autism. Thank you Ken!!

What’s in your water?

Like many American cities, many neighborhoods in and around Chicago struggle with poor water quality. Given the age of municipal pipes, lead contamination is particularly concerning. A 2018 Chicago Tribune report found that 30% of sampled homes had lead levels above 5 parts-per-billion. Health care professionals and researchers agree: there is no such thing as ‘safe’ levels of lead exposure. Lead can make adults sick and impair the proper growth and development of children.

Most lead is delivered to the home through aging, lead service lines. Cities are slowly replacing these lines, but experts advise homeowners take steps to protect their drinking water until this transition is complete. Their recommendation: drinking water filtration systems.

A water filtration system removes lead and other contaminants from water before it reaches your sink faucets, refrigerator, or shower head. By doing so, it drastically improves both the taste and quality of your water.

“Ray’s customer service and plumbing expertise was second to none. Cannot recommend him and this company enough, they’re totally legit.”

“I have to say it was a pleasure working with King. I would highly recommend them and will definitely use them in the future.”

Reverse Osmosis

We install reverse-osmosis (RO) home water filtration systems. Either mounted below your kitchen sink or providing whole-home water filtration, RO is the solution to your water quality concerns.

Water Softeners

Hard water is rough on your appliances and pipes. It leaves scaling on faucets and fixtures, and adds a strange taste to drinking water. Have us install a water softener in your home.
