Oasis Plumbing, Heating & Cooling Offers Seasonal Maintenance Plans

Commercial Heating Solutions for Elmhurst Businesses

When winter temperatures plummet across Elmhurst, IL, maintaining a comfortable and productive environment for employees, customers, and tenants becomes paramount. At Oasis Plumbing, Heating & Cooling, we understand that commercial heating systems face unique demands compared to residential units, requiring robust solutions that can handle larger spaces, longer operating hours, and diverse comfort zones throughout your facility. Commercial properties in Elmhurst experience significant heating challenges due to the region’s harsh winters, where temperatures regularly drop below freezing from December through February, placing extraordinary demands on heating equipment.

Our approach to commercial heating encompasses everything from initial system design and installation to ongoing maintenance and emergency repairs. We recognize that each business operates differently, whether you’re managing a retail storefront on York Street, operating a warehouse facility near the industrial corridor, or maintaining office spaces in downtown Elmhurst. Since 1997, Oasis Plumbing, Heating & Cooling & Cooling has delivered quality customer service, reliability, and expertise in heating, cooling, and ventilation to our residential and commercial clients, giving us deep insights into the specific heating requirements of Northern Illinois businesses.

Understanding Commercial Heating System Options

Commercial heating systems differ substantially from residential equipment in both scale and complexity. Rooftop units remain popular choices for many Elmhurst businesses, offering efficient heating while preserving valuable interior space. These packaged systems combine heating and cooling capabilities, making them ideal for single-story commercial buildings and retail spaces. We frequently install and service these units throughout the area, particularly in shopping centers and standalone commercial properties where roof access allows for straightforward maintenance and replacement procedures.

Boiler systems represent another cornerstone of commercial heating, particularly in older Elmhurst buildings and multi-story facilities. These systems distribute heat through radiators or radiant floor systems, providing consistent warmth even during the coldest January nights. Modern high-efficiency boilers can achieve efficiency ratings exceeding ninety-five percent, dramatically reducing operating costs compared to older models. We specialize in both steam and hot water boiler systems, understanding the intricacies of each type and how they perform in commercial applications throughout the Chicago metropolitan area.

Energy Efficiency and Cost Management Strategies

Managing heating costs remains a critical concern for Elmhurst businesses, especially given the extended heating season that typically runs from October through April. We implement comprehensive energy management strategies that begin with proper system sizing and selection. Oversized equipment cycles frequently, wasting energy and creating uncomfortable temperature swings, while undersized systems struggle to maintain comfort during peak demand periods. Our highly-trained technicians, and responsive support staff, offer customized solutions to fit your budget, ensuring optimal system performance without unnecessary expense.

Advanced control systems and building automation represent powerful tools for reducing commercial heating costs. Programmable thermostats and zone controls allow different areas of your facility to maintain appropriate temperatures based on occupancy and use patterns. For instance, warehouse areas might require minimal heating compared to office spaces, while conference rooms need rapid temperature adjustment capabilities. We install and configure sophisticated control systems that integrate with existing building management platforms, providing real-time monitoring and adjustment capabilities that can reduce heating costs by twenty to thirty percent annually.

Maintenance Programs and Service Excellence

Preventive maintenance forms the foundation of reliable commercial heating operation. Our comprehensive maintenance programs address all critical system components, from heat exchangers and burners to control systems and safety devices. Regular maintenance extends equipment life, prevents costly breakdowns, and maintains peak efficiency throughout the heating season. Serving our customers in Chicago and the Northern Suburbs for over 20 years has taught us that proactive maintenance costs far less than emergency repairs and system downtime.

  • Quarterly inspections identify potential issues before they cause system failures
  • Annual tune-ups optimize combustion efficiency and heat transfer
  • Filter replacement programs maintain indoor air quality and system efficiency
  • Combustion analysis ensures safe and efficient burner operation
  • Control calibration maintains accurate temperature regulation

Emergency Response and Repair Services

Despite excellent maintenance, heating emergencies can still occur, often during the worst possible weather conditions. We maintain a fleet of fully-stocked service vehicles and experienced technicians ready to respond to heating emergencies throughout Elmhurst and surrounding communities. Our diagnostic expertise allows us to quickly identify problems ranging from failed ignition systems to compromised heat exchangers, minimizing downtime and restoring comfort rapidly.

Commercial heating repairs require specialized knowledge of various system types and configurations. We stock common replacement parts for major commercial equipment brands, enabling same-day repairs for many issues. When components require ordering, we work with our extensive supplier network to source parts quickly, often obtaining hard-to-find components for older systems that other contractors cannot locate. This commitment to comprehensive service has established us as the reliable HVAC team for numerous Elmhurst businesses.

Planning for System Replacement and Upgrades

Commercial heating systems typically operate for fifteen to twenty-five years, depending on equipment type, usage patterns, and maintenance history. We help businesses plan for eventual system replacement, providing detailed assessments of existing equipment condition and projected remaining service life. This proactive approach allows for budgeting and scheduling replacements during optimal times, avoiding emergency replacements during peak heating season when equipment availability may be limited and installation costs higher.

Modern commercial heating equipment offers substantial improvements over systems installed even ten years ago. Variable-speed motors, modulating burners, and condensing technology deliver exceptional efficiency gains that often justify replacement of functioning but inefficient older equipment. We perform detailed return-on-investment analyses, considering factors including current energy costs, available utility rebates, and projected maintenance expenses to help businesses make informed decisions about heating system upgrades.

The commercial heating landscape continues evolving as Elmhurst businesses seek sustainable, cost-effective solutions for their facilities. We stay current with emerging technologies and industry best practices, ensuring our clients benefit from the latest advances in commercial heating technology while maintaining the reliability and performance their operations demand.

Customer Reviews

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 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.

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.

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.

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.

Emily H.

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.

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.
Super efficient, knowledgeable, kind, prompt, and communicative - everything you could want in a service. 10/10 recommend!
The plumber was very knowledgeable and competent. He took the time to explain what he was doing and answered a bunch of my questions, even ones that weren’t related to this job. Really great service.
Oasis is a first class HVAC company. Oasis installed a new MagicPak unit for my condo in River North 1 year ago. Oasis completed the 1 year service as well. All of the services that Oasis provided were excellent. This includes system knowledge, system installation, office notifications for progress updates, check-ins for satisfaction responsiveness and price. If you need a new system, system repair or annual system service Oasis is your best choice!

I have had Oasis for HVAC maintenance & repairs in the past. This time I had a broken garbage disposal. Chris was very prompt & explained the problem.

The Oasis crew replaced our HVAC system including AC compressor in just over half a day. They did a fantastic job - delivered what was promised - install looks neat and tidy. They had to get the AC compressor onto the roof of our 3 story building. The crane operator they used was quick and professional. I would recommend Oasis for maintenance and installs of HVAC systems. Great company to work with!

In my 10+ years of living in Chicago, I have had unpleasant experiences being upsold to and mansplained at about HVAC systems. Chicago weather can be so dramatic and that does take a toll on the systems, but I can confidently say the folks at Oasis are the best. Their engineers are super knowledgeable and kind (shoutout to Danny for being our go-to). Their maintenance package makes everything easy and is fairly priced. Their communication / customer service is great. They are an ultimate ally in homeownership.

Response from the owner:Thank you, John, for your kind words about Mike's work and reliability; we appreciate your trust and are grateful to be able to work with you!
Great experience, from making the appointment to having my air conditioner fixed this morning. The technician (Joe) was prompt, kind, efficient & knowledgeable. He explained my options and everything was resolved to my satisfaction. I signed up for their special service package, which was free and ended up saving me money!
Response from the owner:Thank you, Wendy, for sharing your wonderful experience! We're glad to hear that Joe provided great service, and that you found value in our program. Your satisfaction means a lot to us!
A great experience with Oasis from start to finish. When my AC died Mike himself came the next day (Sunday morning) with a short term fix. Installation of new AC and furnace Tuesday afternoon by Anel and Vaha was a pleasure - prompt, professional, skilled, and very responsive.
Response from the owner:Thank you, Kathy, for your wonderful feedback! We're glad Mike could assist you promptly and that Anel and Vaha provided a great installation experience. Your satisfaction means a lot to us!
Had a great experience with Oasis replacing my 20+ year-old AC and furnace. Mike (owner) personally came to quote a new system (at a 20% savings compared to ABC), and was able to schedule next-day installation.

The 3-man team did a great job creatively working through space constraints and had the new system up and running in no time. They even installed 3 new smart thermostats at no extra cost. Would highly recommend Oasis for your HVAC needs.
Response from the owner:Thank you, Kevin, for your fantastic review! We're glad to hear you had a great experience with Mike and our team during your AC and furnace replacement. Your recommendation means a lot to us!
Professional, friendly
Response from the owner:Thank you, Robert, for your kind words about our team; we truly appreciate your feedback!
Excellent plumber. He arrives ON TIME and is very professional. The quality of work, efficiency and price makes me very happy. Will definitely be giving him all our plumbing work.
Response from the owner:Thank you, Ari! We're glad to hear that you appreciate the professionalism and quality of work. We look forward to assisting you with all your plumbing needs in the future!
Our A/C stopped working during a heat wave and we called Oasis after having mediocre experiences with other providers in Chicago. They were able to come out in less than 24 hours and diagnosed that we just needed to clean our outdoor units and replace our filters. After doing that, magically everything worked and we had cool air again. They didn’t try to upsell us or repair something that doesn’t need to be repaired. Love their honesty and we’ll use them again.
Response from the owner:Thank you, Steven, for your kind words and for choosing Oasis; we're glad we could help get your A/C back up and running quickly. We appreciate your trust and look forward to serving you again! We're here for all of your HVAC and Plumbing needs!
Oasis helped me replaced the AC cooling system. They are super professional and patient with all my installation question. Will definitely work with Oasis in future.
Response from the owner:Thank you, Haotian, for your kind words! We're glad to hear that our team was professional and helpful during your AC installation. We look forward to working with you again in the future! We're here for all of your HVAC and Plumbing needs!
Quick service… Fair prices… Good work.
Response from the owner:Thank you, Captain, for your kind words about our quick service and fair prices; we appreciate your support and are glad you had a great experience! We're here for all of your HVAC and Plumbing needs!
Set an appointment for 10am. At 10:20 they let me know they would be an hour late. Changing my plans, I found someone to come and let them in. They must not have pushed the doorbell all the way in, since the person in the house did not hear them. I missed a call from them at 11, but called back within 10 min. They had already moved on, canceled my appointment, and refused to come back the same day. Definitely frustrating and hypocritical after making me wait around all morning. Not nice when your air has been out for multiple days in the heat of the summer.
Best possible way to do home repair if you can't do it yourself for free. Thanks guys!
Response from the owner:Thank you, Kevin! We're glad you found our service helpful for home repairs, and we appreciate your shout-out to the team! We're here for all of your HVAC and Plumbing needs!
As. Real Estate Broker, I only surround myself with the best service providers for my clients. Oasis is the best. Prompt, honest, competent pricing, and very professional. I highly recommend Oasis. You will not be disappointed.

Response from the owner:Thank you, Nathan! We're glad to hear you had a quick and fantastic experience with our team and the home warranty representative. Your feedback means a lot to us! We're here for all of your HVAC and Plumbing needs!
Our A/C went out. They were able to come the same day (Sunday) and have a look. They figured it out within 5 minutes and said they could be back the next morning. They came back on time and made the repair. Easy as can be and both techs were extremely polite and helpful. I signed up for their preventative maintenance program.
Response from the owner:Thank you, Alan, for your kind words! We're glad our team was able to assist you promptly and that you found the service easy and helpful. Welcome to our preventative maintenance program! We're here for all of your HVAC and Plumbing needs!

Completely agree with all the 4/5 reviews. They were very flexible in scheduling the service around my schedule. Worked quickly to determine the issue with my HVAC. Gave me a thorough explanation of the issue. Since it seemed like a common problem they a repair ready at hand. Even did some additional clean up of my outside unit. Wonderful service!

Response from the owner:Thank you, Joshua, for your kind words about Oasis; we appreciate your feedback and are glad to hear you had a positive experience with our team! We're here for all of your HVAC and Plumbing needs!
I had a really positive and efficient experience with Oasis. The quote was easy to schedule as was the work that needed to be done. The team was very flexible with a few different proposals, and helped me troubleshoot an issue that came up when my HOA was being difficult about where the condenser could be placed. Their creative solutions were immensely helpful and got us much needed air-conditioning just before the summer heat waves. They also caught an issue that my electricians made, which saved a lot of headache in the future for other projects and to make sure that my unit would stay healthy.
Response from the owner:Thank you, Maura, for your wonderful feedback! We're glad to hear that our team was able to provide flexible solutions and assist with your HOA challenge, ensuring you got the air-conditioning you needed. Your satisfaction means a lot to us!

Response from the owner:Thank you, Chris, for your wonderful feedback! We're glad to hear you had a great experience with our team . We look forward to working with you in the future!
I was extremely pleased with my experience with Oasis! From the prompt scheduling to the expert service, an all around great experience. I had a 10:00 am appointment and the tech was running late. He had the courtesy to call and let me know he would be running late. Little thing, but much appreciated! Makes a huge difference. When he arrived he was very professional, knowledgeable, and completed the work in a timely manner. I will continue to use and recommend Oasis. I’ve had neighbors use Oasis as well, and they have also been pleased. Thanks!
Response from the owner:Thank you, Eric! We truly appreciate your kind words and are glad to hear you had a great experience with our team. Your support means a lot to us, and we look forward to serving you and your neighbors again!
Friendly, efficient, and easy to work with!

I have been an Oasis customer (and fan) for over 20 years! I have only experienced the BEST service and professional care for all these years - their staff is excellent (and everyone has been there a long time so my experts keep coming back year after year). I feel known by their staff which gives me great peace of mind when they arrive to do a job…I know it will be done correctly, thoroughly, quickly, promptly and efficiently - and with a warmth and kindness that leaves me smiling. The consistency is so appreciated. I would never use anyone else!

Oasis did an amazing job replacing my 20 year old HVAC unit today. Fernando, Michael, and their team were prompt, professional, friendly, and efficient. The office was also great to work with and scheduled me for installation the next day. Their quote was the most cost friendly of the several I received. Highly recommend.
