Heat Pump Replacement in Addison, IL

When your heat pump begins showing signs of failure or inefficiency, replacement becomes a critical consideration for maintaining year-round comfort in your Addison home. At Oasis Plumbing, Heating & Cooling, we understand that heat pump systems serve as the backbone of your home’s climate control, providing both heating and cooling capabilities through a single, efficient unit. Our extensive experience serving customers in Chicago and the Northern Suburbs for over 20 years has given us deep insights into the unique challenges that Illinois weather presents to these systems.

Heat pumps in Addison face particularly demanding conditions, from sweltering summer humidity to harsh winter freezes that can drop well below zero. These extreme temperature swings place significant stress on heat pump components, especially on systems that have been operating for a decade or more. We’ve observed that most heat pumps in our service area begin experiencing efficiency declines after about 10 to 12 years of operation, though this timeline can vary significantly based on maintenance history, usage patterns, and the quality of the original installation.

Signs Your Heat Pump Needs Replacement

Recognizing when replacement becomes necessary rather than continuing with repairs requires understanding the key indicators of heat pump deterioration. One of the most common signs we encounter involves inconsistent heating or cooling throughout your home, where certain rooms remain uncomfortable despite the system running continuously. This often indicates that the heat pump’s capacity has diminished due to compressor wear or refrigerant issues that simple repairs cannot adequately address.

Rising energy bills despite unchanged usage patterns represent another critical warning sign that replacement may offer better long-term value than continued repairs. We frequently analyze utility bills with our Addison customers and find that aging heat pumps can consume 40 to 50 percent more electricity than modern, high-efficiency models. Strange noises emanating from the outdoor unit, including grinding, squealing, or rattling sounds, typically indicate mechanical failures within the compressor or fan motor assemblies that often make replacement more economical than extensive component repairs.

Frequent cycling, where the system turns on and off more often than normal, suggests the heat pump struggles to maintain desired temperatures efficiently. This behavior not only increases energy consumption but also accelerates wear on electrical components and mechanical parts. Additionally, if your system still uses R-22 refrigerant, which has been phased out due to environmental concerns, replacement becomes practically mandatory as this refrigerant becomes increasingly scarce and expensive.

Advanced Heat Pump Technology and Efficiency Standards

Modern heat pump technology has evolved dramatically over the past decade, offering features and efficiency levels that weren’t available when many existing systems were installed. Today’s heat pumps incorporate variable-speed compressors that adjust output based on actual heating or cooling demands, providing more consistent temperatures while using significantly less energy than single-stage units. These advanced systems can modulate their capacity from as low as 25 percent to 100 percent, ensuring optimal comfort without the energy waste associated with constant on-off cycling.

The efficiency ratings of contemporary heat pumps far exceed older models, with many achieving SEER ratings above 20 for cooling and HSPF ratings exceeding 10 for heating performance. 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. We stay current with these technological advances to ensure our customers receive maximum value from their replacement investments. Smart thermostats integration capabilities allow homeowners to optimize their heat pump operation through programmable schedules, remote control via smartphone apps, and learning algorithms that adapt to household patterns automatically.

The Replacement Process and Installation Excellence

Our heat pump replacement process begins with a comprehensive assessment of your home’s specific heating and cooling requirements. We perform detailed load calculations that consider factors including square footage, insulation levels, window efficiency, and directional exposure to ensure proper system sizing. Oversized or undersized heat pumps create comfort problems and efficiency issues, making accurate sizing calculations essential for optimal performance.

During the replacement installation, our highly-trained technicians follow meticulous procedures to ensure every component functions correctly from day one. We carefully remove the old system while protecting your property, properly recovering any remaining refrigerant according to EPA regulations. The new outdoor unit placement receives special attention, ensuring adequate airflow clearance, proper drainage, and minimal noise transmission to living spaces. Indoor air handler installation involves verifying proper ductwork connections, sealing any air leaks, and confirming appropriate refrigerant line routing and insulation.

Our installation process includes several critical steps that differentiate professional replacement from basic equipment swaps:

  • Ductwork evaluation and modification: We inspect existing ductwork for leaks, restrictions, or sizing issues that could compromise new system performance
  • Electrical system verification: We ensure electrical circuits meet the new heat pump’s requirements, upgrading wiring or breakers when necessary
  • Refrigerant line replacement: We install new, properly sized refrigerant lines rather than reusing old lines that may contain contaminants
  • System commissioning: We perform comprehensive startup procedures, verifying refrigerant charge, airflow rates, and temperature differentials
  • Control system programming: We configure thermostats and zone controls for optimal comfort and efficiency

Investment Considerations and Long-term Value

Heat pump replacement represents a significant investment in your home’s comfort infrastructure, typically ranging from $5,000 to $12,000 depending on system capacity, efficiency ratings, and installation complexity. However, this investment often pays for itself through reduced energy costs, fewer repair expenses, and enhanced home value. Modern heat pumps can reduce heating and cooling costs by 30 to 50 percent compared to systems installed 15 years ago, with many Addison homeowners recovering their investment within five to seven years through energy savings alone.

Our responsive support staff offers customized solutions to fit your budget, including various efficiency levels and features that balance upfront costs with long-term operating expenses. We help customers understand available utility rebates and tax incentives that can significantly reduce replacement costs. Many high-efficiency heat pumps qualify for federal tax credits and local utility rebates that can offset thousands of dollars from the total investment.

Warranty protection provides additional value, with most new heat pumps including 10-year parts warranties and compressor coverage. We stand behind our installation work with comprehensive labor warranties, ensuring your investment remains protected for years to come. Regular maintenance through our service programs extends equipment life and maintains warranty validity while preventing unexpected breakdowns during extreme weather conditions when you need your system most.

The decision to replace your heat pump involves evaluating current system performance against the benefits of modern technology and improved efficiency. Our team at Oasis Plumbing, Heating & Cooling provides honest assessments and recommendations based on your specific situation, helping you make informed decisions that deliver maximum comfort and value for your Addison home.

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 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 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.

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.

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 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.

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 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!
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. 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.
Response from the owner:Thank you for the fantastic review Nicole! We loved being of service to you and hope we can assist you again soon.
Joseph did a great job!
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!
Joseph was great! He helped explain to me what was wrong with my furnace and what my options were.
Joseph was quick and efficient!
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!
Great service from Joseph! Diagnosed the issue and was very transparent throughout the whole visit.
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.
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!
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.
I’ve used Oasis for years and they are very timely and professional
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. *****
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
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!
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
Very quick and about 5000 cheaper than the first estimate. Fernando was good
Joseph came out and provided good info and troubleshooting. Good service
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.
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!
I had an excellent experience with Oasis Heating & Cooling. Their service was fast, professional, and very reliable. A special thank-you to Naem and Mike — they were both extremely helpful and made sure everything was done the right way. They explained everything clearly and took great care of my home.
I’m really happy with their work and definitely recommend Oasis Heating & Cooling to anyone who needs honest and quality service! 💯🔥
The customer service at Oasis is top tier! The office assistant, Chris was pleasant in answering my questions and directing me in the right direction!
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.
Oasis Plumbing, Heating & Cooling truly exceeded my expectations! Michael was exceptionally helpful and displayed remarkable honesty throughout the entire process. He took the time to explain each step clearly and answered all my questions with patience. The quality of work was outstanding, and I genuinely appreciated his dedication to ensuring everything was done right.
I called Oasis because I had no heat and the Office Staff was friendly, helpful, and Professional. Its was clear they really wanted to help! The tech's were very kind, show up on time, actually helpful and very knowledgeable. They weren't just trying to sell me stuff I didn't need. Planning on using them again!
Prices are very reasonable and staff super friendly! Was able to get a same day appointment to get my non-functioning HVAC system looked at. Thank you Fernando and Mikey for coming to my rescue!
Joseph was great! Showed up on time, was very courteous and explained everything he was doing.
Great service, fair pricing and knowledgeable techs

This is an honest company with superior service. They were at my home within 2 hours from the time I called. My technician, Damir, was fantastic. He diagnosed my furnace issue quickly and knew exactly what he was doing. Extremely polite and knowledgeable. I give Oasis my highest recommendation.
Response from the owner:Thank you, David! We appreciate your kind words about our service and are glad to hear that Damir provided you with excellent support. Your recommendation means a lot to us!
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.
Response from the owner:Thank you, John, for your fantastic review! We're glad to hear that you had such a positive experience with our team, especially with Joseph. Your recommendation means a lot to us, and we look forward to serving you in the future!

Response from the owner:Thank you, Debbie! We appreciate your kind words about Damir and our scheduling process. Your feedback means a lot to us!
I can’t say enough good things about Oasis Plumbing, Heating & Cooling. They came out on a Saturday in terrible weather when every other company either wasn’t answering or was quoting outrageous weekend rates. My Nest thermostat wiring and furnace configuration needed attention, and they handled it quickly and professionally.

Naem, the technician, was on time, knowledgeable, and incredibly kind throughout the entire visit. He explained everything clearly and made sure the system was functioning perfectly before he left. The gentleman who answered the phone was just as impressive — respectful, accommodating, and genuinely helpful when I called in desperate need of assistance.

Thank you so much for coming through when it mattered most. You truly saved the day for me. Highly recommend! 👏🔥
Response from the owner:Thank you, Sidney! We're so grateful for your kind words and are glad our team, including Naem and our phone support, could assist you during such a challenging time. Your recommendation means the world to us!
Super easy to work with and the quote was below what another company gave. They showed up on time and were able to install my new furnace before it got too cold out
Response from the owner:Thank you, Emily! We're glad to hear that you found our service easy to work with and that we could provide a competitive quote. It's great to know we could get your new furnace installed just in time for the colder weather!
