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

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.

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.

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.

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 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.

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. I also delightfully surprised that they could schedule a 7 AM appointment so I didn’t have to miss any work. On the day of my appointment, Joseph arrived at 7 exactly! He was also courteous, informative, and efficient. He sealed the deal on me being a lifetime customer of Oasis. I highly recommend everyone give this outfit a lot of consideration when deciding who to call. You won’t regret it.

We had an excellent experience with the AC technicians from Oasis. They quickly investigated the issue with our AC system early in the morning and were able to install a brand-new unit the very same day. During a heat wave, their fast response saved us from having to spend the day and another night in an unbearably hot condo. The team was extremely courteous, professional, and efficient throughout the entire process. We truly appreciated their responsiveness, clear communication, and quality work. Highly recommend Oasis for their outstanding service!

Oasis arrived on time to dismantle my 16 year old AC and carried the new AC up 4 flights in a tight staircase, all professionally done. The installation was completed in 4 hours and the result vastly improved not just the coolness of our home but the noise factor, it is unbelievable how much quieter with the new system. This is my 2nd experience with Oasis and I highly recommend and trust their team.

I have been using Oasis for several years. They installed my Space Pak a/c system, as well as (later) a new hot water heater. They service my boiler and the Space Pak and the hot water heater, on a regular basis. Communication is always excellent. Technicians are knowledgeable and friendly. And those few times when I've had an emergency, they've been there quickly (and times where I've had concerns, only to determine that it was my stupidity, they haven't charged me for the visits). Really pleased with the service!
Response from the owner:Thank you, Evan! We truly appreciate your loyalty and are glad to hear you’re satisfied with our communication and service. It's great to know our team has been there for you during emergencies. Your kind words motivate us to keep delivering excellent service!
