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 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.

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 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.

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.

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 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.
Mike (the owner of the company) answered all of my questions and provided a competitive quote for an American Standard furnace and a Aprilaire fan powered humidifier. The installation team was professional, polite, and tidy.
I will not use another HVAC company and I refer Oasis to everyone. They are reliable, professional and a trustworthy company. Their team members are top notch and very knowledgeable. I use them for yearly service on my personal home and also for a multi unit building. They installed a new AC unit in my home and the techs were great. Big thanks to Fernando, Amir and Harvey, and of course Mike too. Their tech Joseph is also great. Will continue to use and recommend. Thanks Oasis!!
Response from the owner:Thank you so much, Billy! We are so happy that we can provide a consistent, professional experience. We love our repeat clients and our entire team will be thrilled to hear your kind words! Thank you for your review, and we look forward to helping you again this fall.

Response from the owner:Thank you for your wonderful feedback! We appreciate your kind words about our scheduling, pricing, and service quality. Your satisfaction means a lot to us!
Our heating wasn’t working and Oasis was able to come over early the next day to fix it. It was a loose wire and a quick fix, so I’m grateful we didn’t have to wait days for an appointment like with other places we’ve contacted before. I really appreciate the friendliness of everyone on the Oasis team and the ease of communication! Thank you and will be calling you guys when needed :)
Response from the owner:Thank you, Magali! We're glad we could quickly resolve your heating issue and that you appreciated our team's friendliness and communication. We look forward to helping you again whenever you need us!
Such a great experience! Learned about them through referrals in Lakeview. We closed on our apt on Tuesday. I was able to have someone come out on a Wednesday to check out the furnace and dehumidifier. The team was able to replace everything by Friday.

I was nervous about up charges with the cold weather just kicking off, but instead, Oasis gave me a discount and helped bring everything up to code (for free or extremely low costs).

Highly recommend! I will be purchasing their 2x a year services too. The guys were such gentlemen, on time and super clean.

Thank you!!
Response from the owner:Thank you, Autumn! We appreciate your kind words and are glad to hear you had a great experience with our team. We look forward to serving you again with your biannual services!

I have been using Oasis Hearing & Cooling for years and they are consistently professional, responsive, and a pleasure to deal with.

Highly recommend! Definitely use them!

Just the Best! Fernando & Michael quickly appeared and got us all set for the cold weather ahead. The two furnaces in our two-flat home were fully cleaned and inspected, new filters installed. All questions answered, no worries. Whew. Highly recommend.
Response from the owner:Thank you, Ellen! We're so glad Fernando and Michael could help get your home ready for the cold weather. We appreciate your recommendation and are here for any future needs!
Joseph was knowledgeable, thorough, professional, and quick.
Response from the owner:Thank you, Andrew, for your kind words about Joseph's exceptional service; we appreciate your feedback and are glad to hear you had a positive experience.
Oasis is an outstanding HVAC contractor. We've used them for over tenyears and they always offer quick, reliable service. We're on their monthly maintenance program for the two systems in our two-flat, and it's a great value. In addition, they recently replaced our furnace and thermostat with an updated model. The work was done at a reasonable price and very quickly, finished in about 3.5 hours. I 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!
Naem found the Nest thermostat problem and solved it very quickly…Thanks, Oasis!
Response from the owner:Thank you, Simon, for recognizing Naem's quick work in resolving the Nest thermostat issue! Your feedback means a lot to us.
Chris was quick to contact me about my water heater and gathered all the details. He also gave me an estimate for a replacement heater and kept me up to date on the work. Everything turned out great and I’m very thankful for Chris’ help. Thank you!

Edit: Bathroom sink faucet replacement 10/16/2025. Chris came by as my old faucet was in bad shape. He explained everything thoroughly and the replacement went smoothly. Very grateful for your help Chris!

I have used Oasis for heating & cooling maintenance previously and this was my first time calling them for plumbing needs. As always, they were great with scheduling and communication. Shout-out to Chris! He was great to work with and efficiently fixed a couple issues happening with my kitchen, sink & disposal.
Response from the owner:Thank you, Kelly, for your kind words! We're glad to hear that Chris provided you with excellent service and that you had a positive experience with our scheduling and communication. We appreciate your support!
Our second time using Oasis and I could not be happier. GREAT service and reasonably priced. The technician, Joseph, was professional, friendly and very knowledgeable. As he was explaining, in detail, what he was doing, I was afraid there was something wrong. But no, everything was fine. He just feels it's best to let us know that he's checking everything. Good guy! So happy I found Oasis! HIGHLY RECOMMENDED!
Response from the owner:Thank you, Vandelisle, for your wonderful feedback! We're so glad to hear that you had a great experience with Joseph and appreciate your recommendation. Your satisfaction means a lot to us!
Amir and Damir showed up exactly at the appointment time. Oasis was very prompt with scheduling and reasonable with pricing for a burned out furnace inducer fan motor.
Response from the owner:Thank you, Pete, for your kind words and for recognizing Amir and Damir's punctuality, as well as our scheduling and pricing; we appreciate your feedback!
Did maintenance for 3 furnaces. They pointed out a few thing that needed attention. Didn't feel pressured to fix them. Overall friendly staff and good price.
Response from the owner:Thank you, Victor, for your feedback! We're glad to hear that you found our staff friendly and appreciated the pricing. Your comfort in the process is important to us, and we appreciate your trust in us to address your furnace maintenance needs.
Response from the owner:Thank you, Elizabeth, for your 5-star rating! We appreciate your support and are glad to have you with us.
I was very impressed by Oasis. I had to replace both my AC and furnace and they were excellent - quick turn around, friendly service and very respectful for my unit. They also accommodated an additional ask to reconfigure some of my duct work to free up some space. All in all I would happily recommend Oasis. The team that worked on my unit were Amir, Damir, Fernando and Michael.

I also had a leak in the Ptrap from the unit above which was separate to the replacement in my unit. Chris the plumber was excellent and did a very professional job. Highly recommended.
Response from the owner:Thank you, Stephen, for your kind words and for recommending Oasis; we’re glad Amir, Damir, Fernando, Michael, and Chris could provide you with excellent service and meet your HVAC and plumbing needs!
Response from the owner:Thank you, Don, for your fantastic 5-star rating! We truly appreciate your support.
Oasis Heating & Cooling did a great job installing a new AC system and a new furnace for me. Their pricing was fair, and they were professional and prompt throughout the process. Hani was excellent as the point person for the entire project, and Fernando, Damir, and Michael did a great job installing the system. I strongly recommend Oasis Heating & Cooling.
Response from the owner:Thank you, Aaron! We appreciate your kind words and are glad Hani, Fernando, Damir, and Michael could provide you with a great experience. Your recommendation means a lot to us!
Got us back up and running the same day. Fast and professional service!
Response from the owner:Thank you, Justin! We're glad to hear you had a positive experience with us. Please don't hesitate to reach out in the future!
Oasis replaced my hot water heater for a good price and performed solid work in a really timely manner. I would use them again if I need any more work done !
Response from the owner:Thank you, Lucas, for your kind words! We're glad to hear you were satisfied with the hot water heater replacement and our team's timely work. We look forward to assisting you again in the future!
I have used Oasis several times in the past for maintenance and finally just had my HVAC system replaced. With each Oasis experience, the techs have been kind, thorough, efficient, and knowledgeable. My system is located in my living room and the techs were so careful with removal of my old unit and installation of the new one. Not a mark or scratch in sight when they left. I can’t recommend them enough!
Response from the owner:Thank you, Stephanie, for your wonderful feedback! We're so glad to hear that our team provided you with a great experience during your HVAC replacement. Your recommendation means a lot to us!

Professional, prompt, and personalized service. Completed replacing two furnaces w/humidifiers, air purifiers, and HEPA filters, thermostat, a/c unit, and repaired duct work as needed all in a timely manner. Properly documented work with photos. As importantly, outstanding communications by their office and field technicians - all under the outstanding leadership of the owner. BRAVO! We have now added them as our plumbing service and annual HVAC check up team!
Response from the owner:Thank you, Laurie, for your kind words and recognition of our team's efforts, including the leadership of our owner; we're glad to be your go-to for plumbing and HVAC services! We greatly appreciate your support and the opportunity to work with such a lovely person!

Oasis service is always friendly, timely, and knowledgeable. I have worked with a number of the techs, including Danny, Hany, the owner, and even the receptionist are all so caring, considerate and helpful. I highly recommend this company for any of your heating and cooling needs.
Response from the owner:Thank you, Dale, for your wonderful feedback! We're glad to hear that our team, including Danny and Hani, provided you with such caring and knowledgeable service. Your recommendation means a lot to us, and we look forward to continuing to work with you!
Much more affordable and way better service than their competitors. I'm looking forward to continuing to work with them.
Response from the owner:Thank you, Andrew! We're so glad you find our service affordable and better than the competition. We appreciate your support and look forward to continuing to work with you as well!
The technician was extremely unprofessional and incredibly rude. He got frustrated by how I might have misunderstood his poorly communicated instructions and started to take out his frustrations on me by throwing accusations in the middle of a service. He barged into the apartment and started to open random doors without my permission trying to find the water heater, despite that I was already there, showing him the way. He did not listen and kept yelling. Horrible and horrifying experience. I don’t know his name because he never said hello or introduced himself but he’s a white man with ginger hair. I’ve worked with many HVAC techs, electricians and plumbers for my job and he surely was THE worst in this country.
Oasis team is professional and great to do business with. They are on time.
Response from the owner:Thank you, Anna, for your kind words about the Oasis team; we appreciate your support and are glad to hear you had a great experience with us!
Had a great experience working with Chris, the plumber from Oasis! My Navien tankless water heater stopped working, and Chris was able to repair the broken parts instead of needing to replace the entire unit, which other companies told me was the best option. He was professional, friendly and did an overall fantastic job. Oasis has also serviced my HVAC system for a few years and the employees are always fair, genuine and seem to be looking out for you :). Thanks for being so great guys!
Response from the owner:Thank you, Katie, for your wonderful feedback! We're so glad to hear Chris was able to help with your water heater and appreciate your kind words about our team and service over the years. Your support means a lot to us!
The tech arrived promptly, checked out our systems and assured me we didn’t need $4,000 in repairs that another company told us we needed. Oasis you have our business now!
Response from the owner:Thank you, Trisha, for your wonderful feedback! We're glad to hear our tech was able to provide you with peace of mind and save you from unnecessary expenses. We look forward to serving you in the future!
Response from the owner:Thank you so much, Lydia, for your 5-star rating! We appreciate your support and are glad to have you with us.
We had a very upsetting experience with Chris from Oasis. My elderly in-laws had their gas shut off by People’s Gas due to a house pipe leak in the basement. My wife and I drove in from the north suburbs to help them, since this was a stressful and unsafe situation.

When Chris arrived, instead of helping, he insisted nothing could be done until People’s Gas marked the lines which was not relevant since the leak was inside the house. While we were actively looking for the official paperwork from People’s Gas (which clearly stated that a contractor needed to pressure test the system at 3 PSI), Chris had no patience, was rude and yelling, and ultimately left before we could even show it to him.

My in-laws were left without answers, without a repair, and with a very unprofessional encounter. This was not the service we expected, and it was a waste of time in a situation where we needed clarity and help.
Courteous, professional, communicative! It was easy to reschedule my appointment over text, and our technician, Amar, was friendly and helpful, answering my many questions
Response from the owner:Thank you, Austin! We're glad to hear that rescheduling was easy for you and that Amar provided friendly and helpful service. Your feedback means a lot to us!
I have been working with Oasis for over p12 years and continue to be amazed at their responsiveness, their professionalism, and the pride + ownership they take in their work - all the techs + the owner himself are great! Highly recommend them
Response from the owner:Thank you, Parag, for your kind words and continued support over the years; we truly appreciate your recommendation and are glad to hear about your positive experiences with our team!
Response from the owner:Thank you, Dirck, for your 5-star rating! We appreciate your support and look forward to serving you again.
Had an issue with an old ejector pump and Chris from Oasis came in and did an awesome job to quickly fit us with a replacement. Will definitely reach out to Oasis again for future plumbing, heating, and cooling needs.
Response from the owner:Thank you, Stephen, for your kind words and for recognizing Chris's efforts; we're glad we could help with your ejector pump and look forward to assisting you with your future plumbing, heating, and cooling needs!
Response from the owner:Thank you, Andrias, for the fantastic 5-star rating! Your support means a lot to us.
I have been doing business with Oasis Heating and Cooling for close to 20 years. Today they conducted a preventative maintenance service call on both my furnace and a/c units. Joseph and Amir were the 2 techs and they both were professional, knowledgeable, and provided efficient service during my hectic work day. Kudos to both of them and to Oasis for continuing to higher great talent.
Response from the owner:Thank you, Cap, for your long-standing support and for recognizing Joseph and Amir's professionalism; we truly appreciate your kind words and are glad to have you as part of the Oasis family.
