Oasis Plumbing, Heating & Cooling Offers Seasonal Maintenance Plans

Professional Furnace Installation Services for Northlake Homes

When winter temperatures drop in Northlake, IL, having a reliable heating system becomes essential for maintaining comfort and safety in your home. At Oasis Plumbing, Heating & Cooling, we specialize in comprehensive furnace installation services that ensure your heating system operates at peak efficiency throughout the coldest months. Our installation process begins with a thorough evaluation of your home’s heating requirements, taking into account factors such as square footage, insulation quality, window placement, and existing ductwork configuration. This detailed assessment allows us to recommend the ideal furnace size and type for your specific needs, preventing the common problems associated with improperly sized units such as short cycling, uneven heating, and excessive energy consumption.

Since 1997, our team has been installing furnaces throughout Northlake and the surrounding Chicago suburbs, developing deep expertise in addressing the unique challenges posed by Illinois winters. We understand that furnace installation represents a significant investment in your home’s comfort and value, which is why we focus on delivering installations that maximize both immediate performance and long-term reliability. Our highly-trained technicians stay current with the latest installation techniques and manufacturer specifications, ensuring every system we install meets or exceeds industry standards for safety and efficiency.

Understanding Your Furnace Installation Options

Modern furnaces offer numerous technological advantages over older models, with efficiency ratings that can dramatically reduce your monthly heating costs. When you choose Oasis Plumbing, Heating & Cooling for your Northlake furnace installation, we guide you through the various options available, including high-efficiency gas furnaces with AFUE ratings up to 98%, two-stage and modulating burners for enhanced comfort control, and variable-speed blowers that improve air circulation while reducing noise levels. These advanced features work together to create a more comfortable indoor environment while minimizing energy waste.

The selection process involves careful consideration of your home’s specific characteristics and your family’s comfort preferences. For example, homes with existing ductwork may benefit from a traditional forced-air furnace, while properties without ducts might be better served by a ductless heating system or a hybrid configuration. We also evaluate factors such as your current gas line capacity, electrical system compatibility, and available space for equipment installation. Our extensive experience serving customers in Chicago and the Northern Suburbs for over 20 years enables us to quickly identify the optimal solution for each unique situation.

The Complete Installation Process

Our furnace installation process in Northlake follows a systematic approach designed to ensure optimal performance and longevity. The installation begins with preparing your home for the work ahead, including protecting floors and furnishings, establishing safe work zones, and coordinating utility shutoffs. We then carefully remove your old furnace if necessary, properly disposing of it according to environmental regulations and recovering any refrigerants or other materials that require special handling.

The actual installation involves precise positioning of the new furnace to ensure proper airflow and accessibility for future maintenance. We meticulously connect gas lines, ensuring all fittings are properly sealed and tested for leaks using advanced detection equipment. Electrical connections receive equal attention, with proper circuit sizing and safety disconnects installed according to local building codes. The venting system installation represents a critical safety component, as improper venting can lead to dangerous carbon monoxide accumulation. We install new vent pipes when necessary, ensuring proper slope and clearances to maintain safe exhaust flow.

Essential Components of Professional Installation

Load calculation and sizing: We perform detailed heat load calculations to determine the exact BTU requirements for your home
Ductwork evaluation: Assessment and modification of existing ducts to ensure proper airflow distribution
Thermostat integration: Installation and programming of modern thermostats for optimal comfort control
Safety device installation: Implementation of carbon monoxide detectors and proper ventilation systems
Air quality enhancements: Integration of filtration systems and humidifiers as needed
Zoning system setup: Configuration of multi-zone controls for customized comfort in different areas

Maximizing Efficiency and Performance

Achieving maximum efficiency from your new furnace installation requires attention to numerous technical details that extend beyond simply connecting the unit. We focus on optimizing airflow throughout your home by properly sealing duct connections, insulating exposed ductwork in unconditioned spaces, and balancing air distribution to eliminate hot and cold spots. These improvements can increase system efficiency by up to 20%, translating to significant savings on your heating bills over the life of the equipment.

Our commitment to quality customer service means we take time to educate you about your new system’s operation and maintenance requirements. We demonstrate proper filter replacement procedures, explain thermostat programming options, and provide guidance on recognizing potential issues before they become major problems. This knowledge empowers you to maintain your investment properly and ensures you receive maximum value from your new furnace installation.

Long-Term Benefits and Considerations

Investing in professional furnace installation through Oasis Plumbing, Heating & Cooling provides benefits that extend well beyond immediate comfort improvements. Modern high-efficiency furnaces typically reduce heating costs by 20-40% compared to units installed just 15 years ago, with some homeowners in Northlake experiencing even greater savings depending on their previous system’s condition. Additionally, new furnaces operate more quietly, distribute heat more evenly, and require less frequent repairs during their initial years of operation.

We understand that reliability and expertise in heating, cooling, and ventilation are essential for both residential and commercial clients throughout the Northlake area. Our responsive support staff remains available to address any questions or concerns that arise after installation, and we offer customized solutions to fit your budget without compromising on quality or safety. The comprehensive warranty coverage on new furnace installations provides additional peace of mind, protecting your investment against unexpected repairs while ensuring continued comfort for your family throughout many winters to come.

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 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 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 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.

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.

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!

Sydney Dusel

Tech and installation members were friendly, knowledgeable, and efficient. The company is extremely easy to reach / provides fair pricing. Our heat went out on 12/30 and someone was out here the next morning on New Years Eve to check it out. Highly recommend for maintenance and repairs!

Jon Heise

Joseph did a great job. Knowledgeable and fast!

Carson Heims

Jennifer Geiman

Team Amir was great! Stayed til everything worked even the day after Xmas. Couldn't recommend them enough.

Joe Davis

Damir, Mark, Joseph, Vaha & Anel installed our new HVAC system and we’re all so profesional and polite! It was a big job and it got done really quickly and felt like they were barely here. We also had duct cleaning which was very though, and Chris did some plumbing and did a fantastic job.

Really blown away by the whole company including Marc the owner who did our quote for the whole thing. Will use for all my hvac needs going forward

Ricky Tang

we have been using Oasis for more than 10 years. they replaced our furnace and AC unit through those years. we have never had any problem with heating or cooling since then. Oasis technicians and managers are courteous and knowledgeable. like today, Joseph, spent extra time to show us how our furnace works and the internal safety features that it has. we really appreciate that!

Parm Purewal

Great experience with Oasis Heating & Cooling. Damir was on time, friendly, and extremely thorough. My furnace needed to be replaced, and he took the time to explain everything clearly while sharing thoughtful maintenance tips, the kind a caring father would give to make sure you’re set up for the long run. He made the whole process easy and stress-free. Highly recommend Damir and Oasis Heating & Cooling.

Rach Ski

Oasis was the quickest to be able to get to us when our heat went out at 9 pm on the coldest day of the year. Fernando and Michael were out the next day with a new unit and went above and beyond! When noticing how bad the a/c unit was with corrosion and mold they were able to replace that as well, timely, and all for a fair price! They were on time, professional, quick, and skillful-thank you!

Sam Hammett

Oasis always delivers! After doing repair work on our AC last year - because the company that did the install wouldn’t return our calls for service - we knew they were the right call for our furnace!

Our furnace motor went out a few days ago - during the winter/a week before Christmas! What a nightmare. Oasis was able to come out first thing the next morning without charging us for an emergency call! Naheem was our repair tech and within 15 minutes he diagnosed the problem and gave us a couple of options with cost estimates. He provided his professional opinion and it felt genuine and unlike a sales pitch!

2 days later, Serge and Harvey came to replace our furnace! They were incredibly kind, respectful and efficient - arriving on time and finishing within the estimated time window. At the end, they did a walkthrough of the new furnace, answered questions about the filters, and even took time to re-affix and correct the settings on our Nest thermostat (that we fully messed up before calling them).

So grateful to find service we can trust!

nicole underhill

Update: I continue to use Oasis for ongoing maintenance and repair. This year Joseph came out for the annual check in. He was very professional, went over the system and helped me to better heat my home for the winter. Thank you!

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing.

Mike came out very late after another company cancelled on me last minute and left me without heat during a brutal cold spell. Mike was able to fix the issue pretty quickly and we soon had heat back. Excellent service, thank you!

Aviva Waldman

Joseph was great! He helped explain to me what was wrong with my furnace and what my options were.

Sabrina Severns

Joseph was quick and efficient!

Patrice

Well, had Oasis out in November for a new furnace and today for a hot water heater that died (and leaked). They are always responsive and Chris did a great job answering my questions. I didn't realize they have a licensed plumber on staff to do this work. Very helpful!

Zach Kennedy

Great service from Joseph! Diagnosed the issue and was very transparent throughout the whole visit.

Ethan York

Easy and courteous. Joseph was efficient and did a great job explaining my furnace system to me and any issues he identified and how to avoid potential issues. Was very satisfied with Oasis.

A Ho

This company is incredibly responsive and professional. They installed two new furnaces and AC units in 2021 in our home. This wasn’t the easiest with one of the furnaces in the attic. They did an excellent job and the units have been working really well. Today, they did some maintenance service on the furnaces and again were friendly, super helpful and very knowledgeable. This is a great company to work with!

Just an update, 12/9/25. We had the units serviced today and Joseph was great. He texted before he arrived allowing me time to put the dogs in kitchen. He was right on time, quick and efficient, and he communicated really well. Plus, he answered all my questions. Really like this company!

Response from the owner:Thank you for your wonderful feedback! We're glad to hear about your positive experiences with our team and that the installations and maintenance went smoothly. Your support means a lot to us!

Fernando and Michael did a fantastic job with the removal and install of our new furnace. Had some helpful tips on operation and maintenance of the new system. Would likely recommend. Very professional and courteous. Great work!

Fam A

This is my third experience having Oasis help with our HVAC and they continue to deliver great results. Michael and Joseph went above and beyond to work on our system. The were super knowledgeable and helpful, and great at communicating and troubleshooting to get our system and keep it in tip-top shape! We also signed up for their annual maintenance program and that will continue to keep our HVAC running smoothly.

Curtis Malasky

Hi bought a high efficiency furnace from Oasis in 2021. Since then I've had one service call that went great. Today I can home from a trip to find a house without heat. It was snowstorm season, and the crew were very busy, but in lieu of a service call, they were able to walk me through a very easy solution which worked great. They've always been very prompt and skilled. *****

Mark Humphries

Rolled with the punches. They were able to replace my water heater that was practically blocked in by my furnace, and kept me well informed along the way as new obstacles popped up. Much appreciation for they're plumber and the HVAC guy for getting it done and putting out some fires along the way

Melissa W

Simply the best. These guys have been helping me for years. They are not only excellent at what they do, they are totally trustworthy. I would not hesitate to hire them. They do my biannual servicing and help when I have issues which has been fairly often. Can’t recommend them highly enough!

Jason Benacka

We called Oasis on a Saturday when our furnace went out and they were able to come out within 2 hours. Joseph was great, quickly assessed our problem and explained the repairs. He was thorough and got our heat back up and running

miguel ortiz

Very quick and about 5000 cheaper than the first estimate. Fernando was good

Natalie Z

Doug Brown

Joseph came out and provided good info and troubleshooting. Good service

Kristin Schrepferman

Thank you to Danny! He was friendly, prompt, knowledgeable and professional. He patiently troubleshot my radiant heat issue, fixed it, and followed up to make sure everything was working properly as the system heated up over several hours. Oasis will be my first call for any future plumbing, heating or cooling needs. The office was also great—easy to reach, quick responses, and simple scheduling. Excellent service at a fair price.

Response from the owner:Thank you, Kristin, for your 5-star rating! We appreciate your support.

Asja Dizdarevic

Top tier service! My son has been experiencing a lot of allergies lately and we decided to reach out to Oasis Heating and Cooling to do an air vent cleaning. Having vents cleaned for a 6 bedroom and 5 bath house is not going to be cheap so we were not shocked that it was costly: it’s not just a quick job, it’s an all day job that requires 4 employees to come out, carry a massive machine in the house, close off all the vents and then do whatever they do to clean the actual vents. The team arrived at 7 am- we were a household that doesn’t wear shoes but they came ready with shoe covers which was really nice because I didn’t prepare any for them. They got straight to work- they were very professional but also very patient and kind to my children who had 1000 questions for them and even challenged them to squats and pushups. The team worked diligently from one room to another and cleaning up after themselves. They took a break for lunch and then came back to finish the job. I was just impressed how they took care of the equipment but were also respectful of our home and made sure to clean up after themselves- triple checking that they put things back and cleaned up. We are very satisfied with their service and work ethic- we highly recommend them.

Two years ago there was a major snow storm on Christmas eve. It was so cold outside (-22 degrees) that the condensation rising from the pipe froze our vent exhaust pipe and caused our attic furnace to shut down. We called Oasis heating and cooling because we have two small children, one that was a baby at the time and the team was at our doorstep the next morning at 6 am to fix it. I could cry right now writing this because our house was freezing and they had a hundred calls coming in that day but because they knew we have small children, came out immediately. You never forget companies like that and their commitment to service, professionalism and kindness. Thank you Oasis Heating and Cooling for everything!

Liqa Hakimi

I had an excellent experience with Oasis Heating & Cooling. Their service was fast, professional, and very reliable.

John Mickelson

Joseph came, explained everything I could've needed to know, showed me pictures of the clog, cleaned it out, couldn't have been easier. This is the furnace they installed 10 years ago, we haven't had any issues in 10 years, and this would have been prevented of we got regular services! Happy to support this local company and they do great work.

I will never call another service. Everything about Oasis is 5 stars. When I called them just to get information about their services and schedule an appointment, the customer service representative was informative and courteous.
