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

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 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 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.

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 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.

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.

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.

Our heating wasn’t working and Oasis was able to come over early the next day to fix it.

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 :)

Autumn Riggenbach

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!

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.

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.

I can’t recommend them enough!
