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.

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.

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.

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.

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.

Joseph and Kwee showed up on time and were very polite. We promptly went to basement where the PVC pipe for my HVAC drainage had snapped in half. Joseph took a look and told me exactly how he was going to fix/replace the broken pipe. I was in a rush because I was on a client call when they arrived (my fault for not checking my calendar). As I ran upstairs, Joseph asked if I wanted to review pricing, which would have slipped my mind had he not stopped me. I’m very grateful he took the initiative to do that. I was surprised at the price of $225 as other companies had quoted me much higher prices. Once that was agreed upon, Joseph and Kwee got to work and were finished in about 20 minutes. The process was seamless and they were careful about being quiet as they were leaving to not disrupt my call. I will definitely be calling Oasis for my next plumbing job. Before and after pics attached. Thank you, guys!

We had Oasis come out to identify a bathroom tub leak. The two guys were helpful, very friendly, and explained everything that was going on in great detail. They really educated us on what our issue was and identified the potential problems in a matter of minutes. Would def recommend.

Oasis Heating and Cooling are definitely the people I recommend for HVAC situations. They’ll be honest with you about what’s going on and what your options are. They may not be the absolute cheapest option but you get what you pay for, and one visit from them compared to multiple visits from someone who is dirt cheap is going to be worth it in the long run.

I have known Mike for over 25+ years. His crew has installed new heating and cooling systems for me, with vents and ductwork installation, hot water heaters and has serviced and maintained same over the years. They are reliable and always available when you need them. Recently, he replaced the heating and cooling system at my parent's house. He came out right away to assess and provide an estimate for the work and 3 days later my parents had their new system to initiate the winter season worry-free. His crew is punctual, very professional and very knowledgeable in their work. I recommend Oasis without reservation.
Response from the owner:Thank you, Leticia! We truly appreciate your kind words and loyalty over the years. It's great to hear that Mike and the team have consistently met your needs and those of your parents. Your recommendation means a lot to us!

We had a new AC and furnace replaced in our condo. The work was completed on a Monday. On Saturday morning, there was a lot of water coming down into the utility closet. We called in to the office immediately and since it was a holiday weekend, there was no availability until Tuesday morning. Saturday evening, as the dripping continued, it dripped into the pan the unit was sitting in, causing the safety switch to shut down the AC. We texted Naim, the estimator, who reached out to the GM. On Sunday morning, Mike and Alan came out to diagnose the problem. They found out that the new installation was not the problem. The water was coming from the condo unit above us. They went above and beyond by going to the unit and cleaning out the blocked pipe that was the source of the problem. This was done at no charge to us; pretty sure not yo the neighbors upstairs either. I would highly recommend Oasis.
Response from the owner:Thank you, Neela, for your wonderful review! We're glad to hear that Naim, Mike, and Alan were able to assist you promptly and go the extra mile to resolve the issue. Your recommendation means a lot to us!
