Oasis Plumbing, Heating & Cooling Offers Seasonal Maintenance Plans

Professional Heating Installation Services for Chicago Homes and Businesses

When temperatures plummet during brutal Chicago winters, having a reliable heating system isn’t just about comfort—it’s about survival. At Oasis Plumbing, Heating & Cooling, we understand the unique challenges that Chicagoland residents face when winter winds whip across Lake Michigan, sending temperatures well below freezing. Our comprehensive heating installation services ensure your property stays warm and comfortable throughout the harshest months, combining cutting-edge technology with time-tested installation techniques refined over decades of experience.

Chicago’s extreme temperature variations, from sweltering summers to frigid winters, demand heating systems that can withstand significant stress while maintaining optimal efficiency. We specialize in installing furnaces, boilers, heat pumps, and radiant heating systems that are specifically suited to handle the demanding climate conditions found throughout Chicago, Bensenville, Addison, and Elmhurst. Our installation process begins with a thorough assessment of your property’s unique heating requirements, considering factors such as square footage, insulation quality, window placement, and existing ductwork configuration.

Understanding Your Heating System Options

Modern heating technology offers numerous options for Chicago property owners, each with distinct advantages depending on your specific needs and budget considerations. Gas furnaces remain the most popular choice throughout the Northern Suburbs, delivering powerful, consistent heat that can quickly warm even the largest spaces. These systems typically achieve efficiency ratings between 80% and 98% AFUE (Annual Fuel Utilization Efficiency), with high-efficiency models significantly reducing monthly utility costs while maintaining superior comfort levels.

Boiler systems provide another excellent option for Chicago homes, particularly older properties with existing radiator infrastructure. These systems distribute heat through hot water or steam, creating a more even, comfortable warmth that many homeowners prefer over forced-air alternatives. Since 1997, Oasis Plumbing, Heating & Cooling has installed countless boiler systems throughout the region, mastering the intricate piping configurations and control systems that ensure optimal performance. Heat pump technology has also advanced considerably, now offering viable heating solutions even in Chicago’s cold climate, particularly when paired with backup heating sources for extreme temperature days.

The Installation Process: What to Expect

Professional heating installation involves far more than simply connecting a new unit to existing infrastructure. Our comprehensive process begins with load calculations using industry-standard Manual J methodology, determining exactly how much heating capacity your property requires. This scientific approach prevents the common mistake of oversizing or undersizing equipment, both of which lead to inefficiency, discomfort, and premature system failure. We analyze heat loss through walls, ceilings, floors, and windows, accounting for Chicago’s design temperature of -4°F to ensure your system maintains comfort even during polar vortex events.

Following equipment selection, our certified technicians handle all aspects of installation, from removing old equipment to configuring advanced control systems. We carefully position equipment for optimal airflow and accessibility, ensuring future maintenance can be performed efficiently. Ductwork modifications often prove necessary to accommodate new high-efficiency equipment, as these systems typically require different airflow characteristics than older models. Our team meticulously seals all connections, eliminating energy-wasting air leaks that plague many heating installations. Serving our customers in Chicago and the Northern Suburbs for over 20 years has taught us that attention to these details makes the difference between adequate and exceptional heating performance.

Energy Efficiency Considerations and Cost Savings

Energy efficiency stands at the forefront of modern heating installation decisions, particularly given Illinois’s fluctuating energy costs and lengthy heating season. High-efficiency heating systems can reduce energy consumption by 30-50% compared to older equipment, translating to substantial savings over the system’s lifetime. We help customers navigate available rebates and incentives, including ComEd and Nicor Gas efficiency programs that can offset installation costs significantly.

Variable-speed technology represents one of the most impactful efficiency innovations, allowing heating systems to adjust output based on actual heating demands rather than operating at full capacity continuously. This technology not only reduces energy consumption but also improves comfort by eliminating temperature swings common with single-stage systems. Smart thermostats further enhance efficiency, learning your schedule and preferences while providing remote control capabilities that let you adjust settings from anywhere.

Critical Installation Components

  • Proper sizing and load calculations: Ensuring equipment capacity matches your home’s specific heating requirements prevents short-cycling and inadequate heating
  • Ventilation system integration: Coordinating heating installation with proper ventilation maintains indoor air quality while maximizing efficiency
  • Safety device installation: Including carbon monoxide detectors, overflow switches, and emergency shutoffs that protect your family and property
  • Zoning system configuration: Creating independent temperature zones that eliminate hot and cold spots while reducing energy waste
  • Condensate management: Properly routing and draining condensation from high-efficiency systems prevents water damage and system malfunctions

Post-Installation Support and Maintenance

Quality heating installation extends beyond equipment placement, encompassing comprehensive system commissioning and customer education. Our technicians perform extensive testing following installation, verifying proper combustion, airflow, and safety device operation. We measure temperature rise across heat exchangers, check gas pressure, and calibrate thermostats to ensure every component functions optimally. This meticulous approach, developed through our extensive experience providing HVAC installation services throughout Chicago, identifies and resolves potential issues before they impact system performance.

We provide detailed operation instructions, explaining thermostat programming, filter replacement schedules, and warning signs that indicate service needs. Our responsive support staff remains available to answer questions and schedule maintenance visits that preserve your warranty and extend equipment life. Regular maintenance proves especially crucial in Chicago’s challenging environment, where heating systems operate continuously for months. 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, understanding that successful installation marks the beginning, not the end, of our relationship with customers.

Professional heating installation represents a significant investment in your property’s comfort, efficiency, and value. By choosing experienced professionals who understand Chicago’s unique climate challenges and possess the technical expertise to properly size, install, and configure modern heating equipment, you ensure decades of reliable, efficient operation. Our highly-trained technicians, and responsive support staff, offer customized solutions to fit your budget while never compromising on quality or safety standards that protect your investment and family.

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 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.

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 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.

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.

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.

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.
Called and was able to get a same day appointment. The technician, Fernando, was fantastic. He found the issue quickly and had my furnace fixed faster than I expected. He was courteous, knowledgeable, and explained exactly what the issue was and what he did to fix it. Will definitely be calling them
Again if i need hvac services.
Fernando was fantastic.
I had some repairs and maintenance at my property, Fernando was the technician and was very detail oriented and kind! Was able to get all the work done and is very knowledgeable
Honest, professional, and down to earth. They were able to avert an emergency furnace issue for us.
Per Chris ---

They DON'T service my area......
Chicago Englewood area....ummm!!
Chris and Mike just finished replacing my pressurized toilet system. Chris helped me identify the problem in advance and saved me an extra service call. They showed up on time for our appointment and resolved my issues promptly.
Joseph did a fantastic job, he was timely and explained everything he did for the furnace. Always great service from Oasis. Highly recommend.
We had an incredibly smooth time with Oasis. Their turnaround time for both diagnostics/inspection and installation of our replacement furnace was very fast. 10/10 would recommend their services. All three individuals that came over throughout the entire process deserve high praise for their patience, knowledge, and willingness to answer all of our questions. They also provided helpful tips and things to think about for future servicing.
Mark, was out today at my residence for service. He was very knowledgeable and explained clearly what was needed. Very pleased with the service provided by Oasis.
Response from the owner:Thank you, Ellen! We appreciate your kind words about Mark and are glad to hear you were pleased with the service from Oasis.
Joseph was absolutely wonderful and a pleasure to work with. He is so knowledgeable and very kind. Can’t recommend him enough!
Literally had a guy here in 20 minutes. Tech wasted no time diagnosing the problem – bad limit switch for heat. Was not charged emergency service rate due to a cancellation in the area. Part is ordered and on our way back to comfort!
Joseph, the technician, came over to do a maintenance checkup for our 1-year old furnace and to the replace the damper on our Aprilaire humidifier. Joseph replaced the humidifier damper and showed me how to do it myself. After Joseph inspected my furnace he pointed out a potential problem with the compressor. He said that the compressor was overheating and needed to be watched. I live in a condo and will recommend Oasis to my neighbors
Oasis has provided service for my home for 4.5 years and has always been wonderful. Most recently we had Joseph, who was professional, knowledgeable, and not pushy.
Quick to come out and give me an estimate for several repairs
My experience with Oasis Plumbing, Heating & Cooling was excellent from beginning to end. As soon as I called, Natalia picked up and immediately made things easy she was friendly, responsive, and helped me get an appointment without any hassle. The technician arrived exactly when expected, went over everything in clear detail, and completed the job with care and professionalism. Oasis proved to be a trustworthy and efficient company, and I’d happily call them again for any future needs.
I had an excellent experience with Oasis Plumbing, Heating & Cooling. From the moment I called, Natalia in customer service was friendly, quick to respond, and very clear about pricing and scheduling. The technician arrived on time, explained everything in a way that was easy to understand, and worked efficiently without cutting corners.
Choosing Oasis Heating for my furnace and HVAC replacement was one of the best decisions I’ve made as a homeowner in Chicago. From start to finish, the experience was outstanding—with professionalism and genuine care that truly set them apart.

The installation team was not only incredibly skilled but also took the time to ensure every detail was perfect. Their workmanship was remarkable and impeccable, from the initial removal to the seamless setup of my new system. I never once felt rushed—quite the opposite! They patiently walked me through every step and explained exactly what to expect, which made the whole process surprisingly stress-free.

The best part? Their quote was easily the most competitive and reasonable among all the options I considered. Anel, who headed up my project, went above and beyond to help me—listening carefully to my needs and recommending a solution that was truly better than anything else I found. He made sure I understood the benefits of the new system and didn’t hesitate to address any questions I had.

If you’re in Chicago and need HVAC work, I can’t recommend Oasis Heating highly enough. Their team, especially Anel, is professional, honest, and committed to making sure you get the best possible service and solution. Five stars all around!
Been using Oasis for twice a month routine maintenance on my ac/furnace unit and they always are prompt, friendly and have it running great. Prices are reasonable.
Fantastic service! The technician was very nice and educational and informative. He showed up 10 minutes early to the appointment as well and was efficient with my time. Would absolutely recommend to anyone needing any HVAC services.
Oasis installed our furnace a few years back and recently we've been experiencing some issues with a faulty flame sensor. Oasis listened to our concerns, diagnosed the issue, and implemented a fix professionally and economically. They made things right. We received amazing customer service from Natalia and Mike (the owner?) and the on-site technicians Damir and Amir were very thorough and patient describing the issue and potential causes as well as quickly implementing a fix. Oasis does customer service as well as any organization I've dealt with and I can highly recommend them for anyone looking for heating/cooling expertise. Thanks Oasis!
Fernando to the rescue. Oasis is a neighbor of mine and I had heard they were amazing. My furnace wasn’t working so I sent a request after hours and someone got back to me in minutes. Fernando was there at 7am and fixed everything. They are affordable and friendly. I’m was very appreciative of them coming so quickly as the furnace was for my business. I also signed up for the yearly maintenance and they are coming on Monday to do a cleaning. Thanks again.

Response from the owner:Thank you, Madeline! We're so glad to hear that Fernando and Michael provided you with excellent service and support. Your recommendation means a lot to us!
Technician Joseph did a great job in assessing issues with a 25 year old furnace, A/C, & water heater. He was very detailed and thorough in explaining the different options I had with regard to repairing vs. replacing each of them separately or replacing all of them in one shot, while giving me the pros & cons of the different options. He made sure I understood what he was telling me and not rushing explanations.
Response from the owner:Thank you, Michael, for your kind words about Joseph's thorough assessment and his clear explanations. We're glad to hear you felt well-informed about your options!
Joseph the technician was a great help

Furnace maintenance revealed some issues and I decided new vs repair just made more sense based on age. Prices were in line with national averages for the model and installation fees. Oasis is always friendly, responsive and professional!
Response from the owner:Thank you, Patrice, for your kind words! We're glad to hear you found our pricing fair and our team friendly and professional. Your satisfaction is important to us!
Joseph was great. Very nice and informative.
Response from the owner:Thank you, Jacqueline, for your kind words about Joseph; we're glad you had a positive experience!
Oasis has done preventive maintenance on my heater the last two years, and it’s been a very positive experience. Scheduling is easy, they are responsive, and have actual humans involved in the process! (I’m writing this on the heels of dealing with Xfinity, which was a nightmare). The technicians were right on time both times, nice people, and they do good work. Also, they didn’t try to sell me anything I didn’t need, which builds trust. I will use them again next year and in between if anything else comes up that’s in their wheelhouse.
Response from the owner:Thank you, Patty, for your wonderful feedback! We're glad to hear that your experiences with our team have been positive and that our technicians were timely and trustworthy. We appreciate your trust in us and look forward to assisting you again in the future!
Our technician Chris was prepared and easy to work with, as we had two jobs for him. After an estimate, he worked us into his schedule for the next day. He was on time each day and very efficient in how he completed his work. These were both plumbing repairs.

Due to the good work by Chris, when heating season came we had this firm check our heating season. Naim did the initial work and gave us good advice. But several weeks later a leaky humidifier shut down our system. Joseph came out at no charge to get the system working again. There was no charge even though this company had not installed the unit, nor did they cause the problem. Would definitely recommend them to others.
Response from the owner:Thank you, Rick, for your kind words about Chris and his efficient work on your plumbing repairs; we appreciate your trust in us and are glad we could meet your needs! We are here for all of your HVAC and Plumbing needs!
Joseph was great - quickly checked our furnace!
Response from the owner:Thank you, Abigail! We're glad to hear that Joseph provided quick and efficient service for your furnace. Your feedback is greatly appreciated!
Joseph did a great job, heat is working now!
Response from the owner:Thank you, Marcus! We're glad to hear Joseph was able to help and that your heat is working now.
Mark from Oasis was very quick and efficient at checking our furnace and getting the filter replaced. I would use Oasis again the future and would recommend to others.
Response from the owner:Thank you, Ashley! We're glad to hear that Mark provided efficient service with your furnace. We appreciate your recommendation and look forward to serving you again in the future.
Response from the owner:Thank you, Jarrett, for your 5-star review!
Joseph was great! Professional, on time and fast. Provided photos of the work. Would recommend.
