Oasis Plumbing, Heating & Cooling Offers Seasonal Maintenance Plans

Electric Water Heater Maintenance in Lombard, IL

Your electric water heater works hard every single day, providing hot water for showers, dishwashing, laundry, and countless other household tasks. Despite being one of the most relied-upon appliances in your home, it rarely gets the attention it deserves until something goes wrong. At Oasis Plumbing, Heating & Cooling, we specialize in comprehensive electric water heater maintenance that keeps your system running efficiently and extends its operational lifespan. Since 1997, we have delivered quality customer service, reliability, and expertise to our residential and commercial clients across Chicago, IL and the surrounding areas, and maintaining your water heater is one of the most impactful services we provide.

Electric water heaters typically last between 10 and 15 years, but that range depends heavily on how well the unit is maintained throughout its life. Without regular attention, sediment buildup, corroded components, and failing heating elements can dramatically shorten the life of your tank. Homeowners in Lombard, IL deal with moderately hard water, which accelerates mineral deposits inside the tank. Routine maintenance addresses these issues before they evolve into expensive repairs or premature replacement. We encourage annual inspections to catch small problems early and keep your energy costs predictable.

What Our Electric Water Heater Maintenance Involves

When our highly-trained technicians arrive at your Lombard home, we perform a thorough, multi-step inspection and service process. Every component of your electric water heater is evaluated to ensure safe and efficient operation. We begin with a visual inspection of the tank exterior, checking for signs of rust, moisture, or structural compromise. Even small amounts of condensation near the base of a water heater can indicate a slow leak that could lead to significant water damage if left unchecked.

The core of our maintenance service involves flushing the tank to remove accumulated sediment. Over months of use, calcium, magnesium, and other mineral deposits settle at the bottom of the tank. This layer of sediment forces the heating elements to work harder, increasing energy consumption by as much as 25 percent according to the U.S. Department of Energy. Flushing the tank restores heating efficiency and reduces the strain on internal components. Our technicians connect a hose to the drain valve, carefully flush the system, and verify that water runs clear before closing the valve and refilling the tank.

We also test the temperature and pressure relief valve, commonly known as the T&P valve. This safety device prevents dangerous pressure buildup inside the tank. A malfunctioning T&P valve is a serious safety hazard, and testing it annually is a critical part of responsible water heater ownership. Our team lifts the valve lever to confirm proper discharge and reseating, replacing the valve immediately if it fails to operate correctly.

Heating Elements and Thermostat Calibration

Electric water heaters rely on one or two immersion heating elements to warm the water inside the tank. These elements are submerged directly in the water and are subject to mineral scale accumulation over time. When scale coats a heating element, it acts as an insulator, preventing efficient heat transfer and forcing the element to consume more electricity. During our maintenance visits, we inspect these elements for scale buildup and corrosion. If an element is degraded, we can replace it on the spot, restoring your heater to full performance.

Thermostat calibration is another essential step that homeowners often overlook. Most manufacturers recommend setting the thermostat to 120 degrees Fahrenheit, which balances comfort with energy savings and reduces the risk of scalding. Our technicians verify that the thermostat reads accurately and adjusts the heating cycle as intended. A thermostat that drifts even a few degrees can result in overheated water that wastes energy or underheated water that fails to meet your household needs. Serving our customers in Chicago and the Northern Suburbs for over 20 years, we have seen firsthand how small calibration adjustments lead to meaningful utility savings.

Anode Rod Inspection and Replacement

The sacrificial anode rod is one of the most important yet least understood components inside your electric water heater. This rod, typically made of magnesium or aluminum, attracts corrosive elements in the water so that the tank lining itself does not corrode. Over time, the anode rod deteriorates completely, leaving the tank vulnerable to rust and eventual failure. Industry experts recommend inspecting the anode rod every two to three years and replacing it when more than six inches of the core wire is exposed or when the rod diameter has decreased significantly.

During maintenance, we remove the anode rod from the top of the tank and assess its condition. In areas like Lombard with moderate water hardness, anode rods may deteriorate faster than in regions with softer water. Replacing a spent anode rod costs a fraction of what a new water heater costs, making this a smart investment in the long-term health of your system. We carry common anode rod sizes on our service vehicles so that replacements can be completed during the same visit.

Signs Your Electric Water Heater Needs Maintenance

Many homeowners are unsure when to schedule maintenance beyond the recommended annual visit. Certain warning signs indicate that your electric water heater needs professional attention sooner rather than later. Recognizing these signals can help you avoid emergency breakdowns and costly water damage.

  • Discolored or rusty hot water coming from your faucets, which may indicate tank corrosion or a depleted anode rod
  • Rumbling or popping sounds from the tank caused by sediment hardening on the bottom and disrupting the heating process
  • Inconsistent water temperatures suggesting a failing heating element or thermostat malfunction
  • Higher than normal electricity bills without a change in usage patterns, pointing to reduced heating efficiency
  • Visible moisture or pooling water around the base of the heater that could signal a slow leak or failing valve

If you notice any of these issues, do not wait for your next scheduled maintenance appointment. Our responsive support staff can arrange a visit to your Lombard home quickly, and our technicians will diagnose the issue and recommend the most cost-effective solution to fit your budget.

Why Proactive Maintenance Matters for Lombard Homeowners

The average American household spends roughly 18 percent of its home energy budget on water heating, making it the second-largest energy expense after space heating and cooling. Proactive maintenance directly impacts that number by keeping your electric water heater operating at peak efficiency. A well-maintained unit heats water faster, cycles less frequently, and draws less electricity per cycle. Over the course of a year, these incremental improvements add up to real savings.

Beyond energy efficiency, maintenance also protects your home from water damage. A catastrophic tank failure can release 40 to 80 gallons of water in minutes, damaging floors, walls, and personal belongings. Insurance claims related to water heater failures average thousands of dollars, and the disruption to your daily routine can be significant. Routine maintenance dramatically reduces the probability of such failures by addressing wear and corrosion before they compromise the tank’s structural integrity.

Our expertise extends across heating, cooling, ventilation, and plumbing services throughout Chicago, Elmhurst, Bensenville, and Addison, IL and surrounding communities.

Customer Reviews

I had a great experience with Oasis. Our furnace had issues on Thursday night and Oasis came at 7am the next morning, and we found out we needed a new one. They provided all the necessary information to our condo building so we could get an emergency replacement on Saturday morning. Within 36 hours we had a brand new furnace and the installation team did a great job communicating on their work and how to use the furnace. The owner, Mike, and his team are great and I really appreciated the attention they gave to this matter. I would highly recommend and will only go to them in the future.

Shane H.

Oasis has always been great to work with and their staff are quick and efficient if issues arise. When our air conditioning broke down during the heat of the summer, they provided a quick replacement at a competitive price. Their staff are always extremely kind, respectful, and knowledgeable.

Sam C.

The folks with Oasis showed up right on time and replaced my entire furnace and condenser in about 4.5 hours. I had just redone my laundry room where the furnace is and they took great care not to damage anything. Overall very happy with the service and very happy with how respectful the installers were.

Josh D.

Oasis was incredibly responsive and efficient! My call to them on a Friday night during a cold spell was returned within 10 minutes and he scheduled a tech to come to my home at 7 the following morning. At 7 the tech was there, examined my furnace confirming that a new motor was necessary. He searched for the part, sent a quote and returned with the motor by noon the same day to install it. You can’t beat that!!! I will be using Oasis for all my future furnace and A/C needs.

Gayle V.

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing. Every tech I’ve had come out is knowledgeable, friendly, and professional. The owner, Mike, is hands on and works with you every step of the way. Highly recommend Oasis.
Services include: furnace and AC replacement; annual maintenance.

Nicole U.

I called Oasis this morning because my furnace was not working. Within 20 minutes their technician, Danny, arrived. Danny was able to assess the situation, provide an immediate fix, and even commit to returning Monday morning to provide additional services needed. Danny was friendly, informative, professional and FAST! I am thankful I called Oasis for my immediate heating needs and that Danny was the technician who arrived. Top notch service! Highly recommend.

Megan R.

Danny and the folks at Oasis got us a great deal on a new furnace and AC. The install took about 4 hours, and they were also super responsive throughout the process. It was about as good of an experience I’ve had with an HVAC company. I’d highly recommend!

Brian C.

Oasis is great! My furnace is almost 30 years old and for a reasonable price they were able to do the repairs. First Danny came to evaluate. He showed me what was wrong. They had to order the necessary parts to fix it. Today Hani and Fernando came to do the repair. They were efficient and courteous. I will definitely use Oasis in the future.

Update on May 2026: Oasis has a great plumbing team now! Thanks Steve and Amer for the smooth water switch change. They are very knowledgeable and patient. Update on April 2026: had my second appointment with Joseph, who was absolutely amazing. I can always learn something useful from him to better care for my system. Highly recommend him and Oasis! Glad I found Oasis to help me maintain my home heating and cooling system! From booking the first visit, to communicating the arrival time, Chris went up and above. My technician Joseph showed up on time and answered all my questions regarding my home furnace and humidifier. Will be working with them annually moving forward!

Oasis arrived on time to dismantle my 16 year old AC and carried the new AC up 4 flights in a tight staircase, all professionally done. The installation was completed in 4 hours and the result vastly improved not just the coolness of our home but the noise factor, it is unbelievable how much quieter with the new system. This is my 2nd experience with Oasis and I highly recommend and trust their team.
Response from the owner:Thank you, Karen, for your wonderful feedback! We're glad to hear that our team was able to provide you with a smooth installation experience and that you're enjoying the improved comfort and quiet of your new AC. We appreciate your trust and loyalty to Oasis!

Oasis is the best heating and cooling company to work with in all of Chicagoland! I will only work with these guys. They are professional, kind and considerate, and truly understand heating and cooling.
Response from the owner:Thank you so much! We know every HOA is different, and we are glad we could get the paperwork figured out so quickly. Thank you so much, and we hope to work with you again this winter!
I have been using Oasis for several years. They installed my Space Pak a/c system, as well as (later) a new hot water heater. They service my boiler and the Space Pak and the hot water heater, on a regular basis. Communication is always excellent. Technicians are knowledgeable and friendly. And those few times when I've had an emergency, they've been there quickly (and times where I've had concerns, only to determine that it was my stupidity, they haven't charged me for the visits). Really pleased with the service!
Response from the owner:Thank you, Evan! We truly appreciate your loyalty and are glad to hear you’re satisfied with our communication and service. It's great to know our team has been there for you during emergencies. Your kind words motivate us to keep delivering excellent service!

I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it. Mike came out to look at the old central air and heating furnace unit which is in the upstairs of our bungalow. Seated horizontally, it was going to take a lot of work to get the old unit out and the new unit in. We selected the American Standard (highest rated in the industry a.k.a. Trane) 80K BTU 2 stage furnace/central air and an American Standard 3.5 ton 13 seer A/C unit outside. The team of 5 guys came out to install it just 4 days after signing the contract promptly at 7:00am and completed the entire job at 2:30pm. They had originally thought it would take a day and a half. I also elected the annual maintenance which they come out 2 times per year and will also cover labor, along with manufacturer's hardware warranty for 10 years. The units are EXTREMELY quiet, you cannot even hear them run. Especially being outside and entertaining the patio. My electric bills are also expected to decrease significantly. The 19 year old previous system originally purchased from Sears was costing an additional $400/month just to run in the summer to to mention the old freon was $220.00 per pound. I am VERY satisfied with Oasis HVAC, quality product, quality service, attention to detail, professional and courteous. They also don't change extra for after hours emergency maintenance and have been easy to reach in the time of need and arrive at the house in 1-2 hours after creating an appointment. Oasis HVAC comes highly recommended from a highly satisfied customer.
Response from the owner:Thank you, Keith, for your wonderful feedback and for trusting Mike and our team at Oasis with your HVAC needs over the years; we're delighted to hear about your positive experiences and are thrilled that you're satisfied with your new system! We look forward to continuing to work with you!

Oasis is an outstanding HVAC contractor. We've used them for our home since 2015 and they always offer quick, reliable service. On their recent AC spring maintenance call at our 2-flat they identified that both of our 13-year-old water heaters are were leaking and in need of replacement, as was one of our AC units. They scheduled the work in less than a week and did the 3 jobs in about 5 hours from beginning to end. We received a good price and the work was well done. We highly recommend Oasis!
Response from the owner:Thank you, Martin, for your wonderful review! We're grateful for your continued trust in Oasis and are glad to hear you’re pleased with our service and the recent furnace upgrade. It's been a pleasure to work with you throughout the years!

I used Oasis for both a/c maintenance and a water heater flushing. Guys were on time and very professional! Fair quote on both services..and didn't try to upsell me on things others had tried to do-luckily I have a friend that's a plumber and said what was needed. Will definitely be calling Oasis for future plumbing needs! Appreciate the honesty. One other company gave me a ridiculous quote..for something I didn't need-won't mention any names-but all reviews mentioned how high their pricing was-do some research!

I have worked with Oasis twice before and both times they have been PHENOMENAL. They're quick, helpful, and actually care about what's best for you, not just what makes them the most money. The first time, my AC went out last summer right before this big heat wave. Every other tech I had out told me I would have to replace the whole thing, and they couldn't do anything for me until after the slate of 95+ degree days we had coming up. Some told me that it would cost thousands to fix my current problem. Oasis came out and 10 minutes later, my tech Damir tells me he's fixed my AC by replacing a part -- he carries a spare in his bag. So he's patched it for the summer -- a $300 solution when I was prepared to spend $8,000+. He also walked me through what was wrong with the system, what would need to be replaced eventually, and how to keep the AC going through the rest of the summer. I felt his price was very reasonable (he even took a little bit off because he misspoke when he told me the original price) and he was able to truly help me, not try to get more money out of me. So this spring, I called them to finally get the AC replaced. First, they came out to do the estimate and explained all the options to getting the AC up the 5th floor. They are very focused on making sure you have a good experience (when I suggested not craning it up all the way, they responded basically "no, that's silly, that would just cost you more money than you need to spend. We're not doing that"). They came out today and in the course of doing the work, found a previously undiscovered leak in the HVAC closet. They immediately called their plumbing team (Amer and Steve) who cancelled other calls to come and help. Amer and Steve thoroughly diagnosed the leak and fixed it fast. They spent almost an hour talking me through the issue and different next steps to get the mold dealt with. The AC work has been great so far -- the team had to move my appointment to Saturday to save me about $9,000 in fees to the city and have been very communicative about the change. TL;DR: If you need a plumbing and heating company, Oasis should be your first call.
Response from the owner:Thank you, Layne, for sharing your excellent experience with us! We're glad Damir could provide a quick and affordable solution for your AC, and we appreciate your kind words about our team's efforts to accommodate you on short notice. Your satisfaction is our priority! We are here for all of your HVAC and Plumbing Needs!

We hit furnace trouble on one of the coldest days of the year, and Oasis still got us in the same day—on-site within two hours of my call. Naem was our technician and was fantastic: kind, quick to diagnose, and had the heat running again in under 30 minutes. They also installed our rooftop A/C and did an excellent job. We’re really grateful for the whole Oasis team and their great service. Highly recommend them to anyone in Chicagoland. Update 4/23/26: our furnace worked great the rest of the season! Also wanted to add we just had our AC serviced today by Joseph at Oasis and he was excellent. Timely, helpful, and laid out repairs that would likely be necessary in the next couple of years. Great service and we’re thankful for making us aware of what to plan for in the future!
