Oasis Plumbing, Heating & Cooling Offers Seasonal Maintenance Plans

Professional Heating Services for Addison Homes and Businesses

When winter temperatures drop in Addison, IL, reliable heating becomes essential for comfort and safety. At Oasis Plumbing, Heating & Cooling, we specialize in comprehensive heating solutions that keep residential and commercial properties warm throughout the harsh Midwest winters. Our experienced technicians understand the unique challenges that Illinois weather presents, from sudden temperature drops to extended cold snaps that can strain even the most robust heating systems. Since 1997, we’ve been the trusted choice for heating services across Addison and the surrounding communities, building our reputation on technical expertise and unwavering commitment to customer satisfaction.

The heating needs of Addison properties vary significantly based on factors like building age, insulation quality, and system type. We work with all major heating system configurations, including forced air furnaces, boilers, heat pumps, and radiant heating systems. Each technology requires specific knowledge and techniques for proper installation, maintenance, and repair. Our highly-trained technicians stay current with the latest industry developments and manufacturer specifications to ensure optimal performance from every system we service.

Comprehensive Furnace Installation and Replacement

Furnace installation represents a significant investment in your property’s comfort and energy efficiency. Modern high-efficiency furnaces can achieve Annual Fuel Utilization Efficiency (AFUE) ratings of up to 98%, meaning nearly all the fuel consumed converts directly into heat for your home. When we assess your heating needs, we consider multiple factors including square footage, ceiling height, insulation levels, window efficiency, and your family’s comfort preferences. This comprehensive evaluation ensures proper sizing, as an oversized furnace cycles too frequently, causing temperature fluctuations and increased wear, while an undersized unit runs constantly without adequately heating your space.

The installation process involves careful attention to ventilation requirements, gas line connections, electrical wiring, and ductwork modifications. We ensure proper combustion air supply and exhaust venting to maintain safe operation and maximize efficiency. Modern furnaces often include variable-speed blowers and modulating gas valves that adjust output based on heating demand, providing more consistent temperatures and reduced energy consumption. Our installation team handles all necessary permits and inspections, ensuring compliance with Addison building codes and manufacturer warranty requirements.

Essential Heating System Maintenance

Regular maintenance significantly extends heating system lifespan while maintaining peak efficiency. Serving our customers in Chicago and the Northern Suburbs for over 20 years, we’ve developed comprehensive maintenance protocols that address common issues before they become costly repairs. During maintenance visits, we perform thorough inspections of heat exchangers for cracks or corrosion, clean and adjust burner assemblies, test safety controls and limit switches, verify proper thermostat operation, and measure system performance against manufacturer specifications.

Dirty filters remain the most common cause of heating system problems, restricting airflow and forcing equipment to work harder. We recommend checking filters monthly during heating season and replacing them according to manufacturer guidelines. Beyond filter maintenance, we inspect and clean blower assemblies, lubricate moving parts, check electrical connections, test carbon monoxide detectors, and verify proper condensate drainage in high-efficiency systems. These preventive measures typically reduce heating costs by 15-20% while preventing unexpected breakdowns during critical weather periods.

Emergency Heating Repair Services

Heating failures often occur during extreme weather when systems work hardest. Our responsive support staff understands the urgency of heating emergencies and prioritizes rapid response to restore comfort and safety. Common heating problems include ignition failures, blower motor malfunctions, thermostat issues, heat exchanger problems, and gas valve failures. Each issue requires specific diagnostic procedures and repair techniques that our technicians master through extensive training and field experience.

Modern diagnostic tools allow us to quickly identify problems using computerized analysis, combustion testing, and thermal imaging. We maintain extensive parts inventory for common repairs, minimizing downtime and repeat service calls. When evaluating repair versus replacement decisions, we consider factors including system age, repair history, energy efficiency, and long-term cost implications. We provide transparent pricing and honest recommendations, helping you make informed decisions about your heating system investment.

Energy Efficiency Solutions and Upgrades

Energy efficiency improvements offer significant long-term savings while enhancing comfort. The Department of Energy estimates that heating accounts for approximately 45% of typical household energy consumption. We offer customized solutions to fit your budget, including programmable and smart thermostat installation, ductwork sealing and insulation, zoning system implementation, and heat recovery ventilator installation. These upgrades work synergistically to reduce energy waste and improve system performance.

  • Smart thermostats learn your schedule and preferences, automatically adjusting temperatures for optimal comfort and efficiency
  • Ductwork improvements eliminate air leaks that waste 20-30% of heated air in typical homes
  • Zoning systems allow independent temperature control for different areas, reducing heating in unused spaces
  • Heat recovery ventilators provide fresh air while capturing heat from exhaust air, maintaining indoor air quality without energy waste

Commercial Heating Solutions

Commercial heating systems present unique challenges requiring specialized expertise. We service various commercial applications including office buildings, retail spaces, warehouses, restaurants, and industrial facilities. Commercial systems often involve rooftop units, multiple zones, complex control systems, and higher capacity requirements. Our commercial service team understands the importance of minimizing business disruption while maintaining comfortable environments for employees and customers.

Preventive maintenance agreements provide scheduled service that reduces emergency calls and extends equipment life. We coordinate maintenance during off-hours to avoid business interruption and maintain detailed service records for warranty compliance and budgeting purposes. Our commercial clients benefit from priority emergency response, volume pricing on parts and services, and comprehensive system analysis for optimization opportunities. We work with property managers and facility directors to develop heating strategies that balance comfort, reliability, and operating costs while meeting all commercial building code requirements specific to Addison and the greater Chicago area.

Customer Reviews

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.

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.

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.

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.

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.

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.
Oasis has always been my go to for service and repair for hvac. Their techs always call if they’re going to be late, which I appreciate. And they want to really work with you and not oversell you on repairs.
Chris, Oasis’ plumber, is super professional and knowledgeable. I will be calling him for all my plumbing needs in the future. Excellent service. Highly recommended.
Joseph & Mark were very efficient & helpful today. They explained everything very well! Please thank them.
Response from the owner:Thank you, Lisa!
I called this company to come look at my furnace. A gentleman by the name of Fernando came out, checked out my unit and he was able to get it up and running in 15 mins! Very fast and reliable. I will be recommending them to my family and friends. Shout out to Fernando for his honesty 🤝
Joseph and Naem were great and right on time. Super helpful and friendly.
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.
Great Prompt service and professional team

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.
Response from the owner:Thank you, James! We're glad to hear that Joseph made a positive impression with his professionalism and efficiency. Your recommendation means a lot to us!
