Whole House Water Filter in Chicago

Do you ever wonder what’s in your Chicago tap water? At Deljo Heating, Cooling & Plumbing, we’ve been keeping Chicagoland homes comfortable since 1922. Now, we’ve expanded our expertise to include water quality. Read on to learn about our whole-house water filter solutions.

Why Chicago Homes Need a Whole House Water Filter

Chicago’s water treatment facilities work hard, but they can’t catch everything. Your municipally-treated water might still contain:

  • Chlorine and chloramines
  • Lead from old pipes
  • Sediment and rust
  • Pharmaceutical residue
  • Industrial contaminants

A whole house water filter from Deljo tackles these issues at the source. After we install your whole-house water filter, you will have access to clean, fresh water from every tap in your home.

Whole House Water Filter FAQ

How does a whole house water filter work?

A whole house water filter is installed at your home’s main water line, treating all the water that enters your house. Most water filters use a multi-stage filtration process to remove contaminants so you can get clean water from every faucet.

Will a whole house water filter affect my water pressure?

When properly sized and installed by Deljo’s experts, a whole-house water filter will not significantly impact your water pressure. We will carefully calculate your home’s water usage to ensure the right system for you.

How often does the filter need to be replaced?

Filter replacement frequency depends on your water quality and usage. Typically, filters need replacement every 6-12 months. We’ll help you set up a maintenance schedule that properly addresses your needs.

How does Chicago’s water quality compare to other cities?

While Chicago’s water meets federal standards, it can still contain contaminants that affect taste, odor, and long-term health. A whole-house water filter provides an extra layer of protection and quality improvement.

This was my first time as a Deljo customer, and I was very pleased. My technician, Giovanni, was very thorough and diligent. He serviced my furnace and identified a faulty sensor that was causing the unit to shut itself down. Deljo ordered the part, and Giovanni replaced it a few days later. Overall, the team at Deljo was great. The dispatcher kept me informed about Giovanni’s arrival time, and the supervisor assisted Giovanni when he was diagnosing the problem with the furnace. I highly recommend Deljo.

I’ve used Deljo for over 10 years now and they always do a good job. Izzy was the technician for this visit and he did an excellent job with my winter maintenance on my multiple units in the household. He also addressed an issue while cleaning the furnace blower wheel. His communication was clear and concise with what he planned to do to address the issue quickly. He was confident and I had 0 concerns or questions. Great job Izzy!

Paul was great! Arrived on time and completed maintenance on my humidifier, tankless water heater, and two furnaces. All work was performed under my Gold Star maintenance program, so all maintenance charges were covered. Paul did provide a few proposals for additional services on furnace & tankless water heater, but those were emailed to me for further consideration. Paul was friendly, knowledgeable, and answered all my questions.

Gabe did an excellent job with our annual service visit. He arrived in the early part of our service window, was friendly and knowledgeable, and got the work done in a very reasonable amount of time. I have great confidence in Deljo, and am a long-time customer.

I’ve been using Deljo for 20 years for HVAC but now venture into enlisting their plumbing services. Bashar was very courteous, efficient & informative, and I’d definitely request him again for the next plumbing job. Great experience!

Working with Deljo is always a good experience, and today’s appointment with Izzy was no different. He was able to come early which actually worked better with our schedules, but called me ahead of time to make sure that was okay. He was friendly and knowledgeable when he explained the work he had done during his visit and our options for fixes. He was also able to schedule a quote appointment for us while he was still here. We would highly recommend working with Izzy and the Deljo team!

Drew performed the seasonal maintenance on my AC. It needed some repairs and updates and he was able to fix everything at the same appointment. He also noticed issues with the hot water heater and we were able to get ahead of that, as well.

I would leave six out of five stars if I could! My technician Jorge went above and beyond on his service. There was buildup in the rental property’s toilet from the previous tenant. One maintenance person did a surface level job of cleaning but did not fully remove the obstruction. Jorge went above and beyond and came to a solution and even explained the perpetual problems older toilet models can cause. Moving forward with this insight, I can perform my own upkeep the previous tenant did not. Thank you kindly!

We just had our new boiler installed by Jonathan and Carlos. First rate work! They arrived on time, removed the old boiler, installed the new unit, and explained the features. Both guys were pleasant. Bring on the cold this winter! We are ready thanks to the team from Deljo.
