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

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 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.

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.

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.
Chris fixed my slow kitchen drain and did a great job! Pricing was fair and upfront and work was completed same day. I’d highly recommend.
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. As he was explaining, in detail, what he was doing, I was afraid there was something wrong. But no, everything was fine. He just feels it's best to let us know that he's checking everything. Good guy! So happy I found Oasis! HIGHLY RECOMMENDED!
Response from the owner:Thank you, Vandelisle! We're so glad you had a great experience with Oasis and that Naem provided you with excellent service. We appreciate your support and look forward to serving you again! We're here for all your HVAC and Plumbing needs!
Amir and Damir showed up exactly at the appointment time. Oasis was very prompt with scheduling and reasonable with pricing for a burned out furnace inducer fan motor.
Response from the owner:Thank you, Pete, for your kind words and for recognizing Amir and Damir's punctuality, as well as our scheduling and pricing; we appreciate your feedback!
Did maintenance for 3 furnaces. They pointed out a few thing that needed attention. Didn't feel pressured to fix them. Overall friendly staff and good price.
Response from the owner:Thank you, Victor, for your feedback! We're glad to hear that you found our staff friendly and appreciated the pricing. Your comfort in the process is important to us, and we appreciate your trust in us to address your furnace maintenance needs.

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.
Response from the owner:Thank you, Stephen, for your kind words and for recommending Oasis; we’re glad Amir, Damir, Fernando, Michael, and Chris could provide you with excellent service and meet your HVAC and plumbing needs!

Oasis Heating & Cooling did a great job installing a new AC system and a new furnace for me. Their pricing was fair, and they were professional and prompt throughout the process.

I have used Oasis several times in the past for maintenance and finally just had my HVAC system replaced. With each Oasis experience, the techs have been kind, thorough, efficient, and knowledgeable. My system is located in my living room and the techs were so careful with removal of my old unit and installation of the new one. Not a mark or scratch in sight when they left. I can’t recommend them enough!
Response from the owner:Thank you, Stephanie, for your wonderful feedback! We're so glad to hear that our team provided you with a great experience during your HVAC replacement. Your recommendation means a lot to us!

Response from the owner:Thank you, Andrew! We're so glad you find our service affordable and better than the competition. We appreciate your support and look forward to continuing to work with you as well!
The technician was extremely unprofessional and incredibly rude. He got frustrated by how I might have misunderstood his poorly communicated instructions and started to take out his frustrations on me by throwing accusations in the middle of a service. He barged into the apartment and started to open random doors without my permission trying to find the water heater, despite that I was already there, showing him the way. He did not listen and kept yelling. Horrible and horrifying experience. I don’t know his name because he never said hello or introduced himself but he’s a white man with ginger hair. I’ve worked with many HVAC techs, electricians and plumbers for my job and he surely was THE worst in this country.
Oasis team is professional and great to do business with. They are on time.
Response from the owner:Thank you, Anna, for your kind words about the Oasis team; we appreciate your support and are glad to hear you had a great experience with us!
Had a great experience working with Chris, the plumber from Oasis! My Navien tankless water heater stopped working, and Chris was able to repair the broken parts instead of needing to replace the entire unit, which other companies told me was the best option. He was professional, friendly and did an overall fantastic job. Oasis has also serviced my HVAC system for a few years and the employees are always fair, genuine and seem to be looking out for you :). Thanks for being so great guys!
Response from the owner:Thank you, Katie, for your wonderful feedback! We're so glad to hear Chris was able to help with your water heater and appreciate your kind words about our team and service over the years. Your support means a lot to us!
The tech arrived promptly, checked out our systems and assured me we didn’t need $4,000 in repairs that another company told us we needed. Oasis you have our business now!
Response from the owner:Thank you, Trisha, for your wonderful feedback! We're glad to hear our tech was able to provide you with peace of mind and save you from unnecessary expenses. We look forward to serving you in the future!
Response from the owner:Thank you so much, Lydia, for your 5-star rating! We appreciate your support and are glad to have you with us.
We had a very upsetting experience with Chris from Oasis. My elderly in-laws had their gas shut off by People’s Gas due to a house pipe leak in the basement. My wife and I drove in from the north suburbs to help them, since this was a stressful and unsafe situation.

When Chris arrived, instead of helping, he insisted nothing could be done until People’s Gas marked the lines which was not relevant since the leak was inside the house. While we were actively looking for the official paperwork from People’s Gas (which clearly stated that a contractor needed to pressure test the system at 3 PSI), Chris had no patience, was rude and yelling, and ultimately left before we could even show it to him.

My in-laws were left without answers, without a repair, and with a very unprofessional encounter. This was not the service we expected, and it was a waste of time in a situation where we needed clarity and help.
Courteous, professional, communicative! It was easy to reschedule my appointment over text, and our technician, Amar, was friendly and helpful, answering my many questions
Response from the owner:Thank you, Austin! We're glad to hear that rescheduling was easy for you and that Amar provided friendly and helpful service. Your feedback means a lot to us!
I have been working with Oasis for over p12 years and continue to be amazed at their responsiveness, their professionalism, and the pride + ownership they take in their work - all the techs + the owner himself are great! Highly recommend them
Response from the owner:Thank you, Parag, for your kind words and continued support over the years; we truly appreciate your recommendation and are glad to hear about your positive experiences with our team!
Response from the owner:Thank you, Dirck, for your 5-star rating! We appreciate your support and look forward to serving you again.
Had an issue with an old ejector pump and Chris from Oasis came in and did an awesome job to quickly fit us with a replacement. Will definitely reach out to Oasis again for future plumbing, heating, and cooling needs.
Response from the owner:Thank you, Stephen, for your kind words and for recognizing Chris's efforts; we're glad we could help with your ejector pump and look forward to assisting you with your future plumbing, heating, and cooling needs!
Response from the owner:Thank you, Andrias, for the fantastic 5-star rating! Your support means a lot to us.
I have been doing business with Oasis Heating and Cooling for close to 20 years. Today they conducted a preventative maintenance service call on both my furnace and a/c units. Joseph and Amir were the 2 techs and they both were professional, knowledgeable, and provided efficient service during my hectic work day. Kudos to both of them and to Oasis for continuing to higher great talent.
Response from the owner:Thank you, Cap, for your long-standing support and for recognizing Joseph and Amir's professionalism; we truly appreciate your kind words and are glad to have you as part of the Oasis family.
Very happy with the service when my AC stopped working. Originally Oasis could not do a consultation on the weekend and they put me on a waitlist. Fortunately they contacted me later that day and scheduled me for the weekend. I ended up having to replace my system and they gave me a fair price with an end of season discount. The workers were on time a couple days later, replaced the system quickly and even installed my smart thermostat at no extra charge. Would use Oasis again in a heartbeat!
Response from the owner:Thank you, Kelsey! We're so glad to hear that you had a great experience with our team and that we could assist you quickly. Your satisfaction means a lot to us, and we appreciate your kind words about our service and pricing. Looking forward to helping you again in the future!
Update for 2025:
Oasis comes through again. I recently learned that Oasis now offers duct and vent cleaning, so when our dryer stopped drying, I knew just who to call. A phone call Monday got me service Thursday morning. As before, the team was prompt, professional, and effective.

Oasis Heating and Cooling have been so helpful to us. A couple of years ago they replaced our heater during a cold snap, and now they have saved us from the heatwave. Our AC went out Saturday afternoon, and they responded to my service request within an hour and had a tech out Sunday morning. Naem assessed the problem, recommended a new unit (ours was more than 15 years old), and installed a temporary replacement part to carry us through until the installation crew could replace the unit on Wednesday. That crew was prompt, polite, and knowledgeable. Though the installation took twice the time estimated because they had to rebuild some of the exhaust chimney, the final price was as in the estimate—no extra charges for labor time. Strongly recommend!
Response from the owner:Thank you, Cynthia, for your wonderful review! We're delighted to hear that our team was prompt and professional, and we're so happy to continue working with you! Your support and recommendation mean a lot to us!
Very easy to work with and honest about expectations
Response from the owner:Thank you, Bobby, for your kind words; we appreciate your feedback and are glad to hear you found us easy to work with!

Oasis went above and beyond to fix a very complex issue with my A/C. Mike was able to come out the day I called, and after some thorough troubleshooting, he was able to diagnose an extremely challenging problem. He kept me informed every step of the way, making sure I understood the issue. To top it off, the pricing was very fair. I really appreciate the excellent service and cannot recommend enough!
Response from the owner:Thank you, Cami, for your wonderful feedback! We're glad Mike could promptly assist you with your A/C issue. Your appreciation means a lot to us!
Super efficient, knowledgeable, kind, prompt, and communicative - everything you could want in a service. 10/10 recommend!

Oasis is a first class HVAC company. Oasis installed a new MagicPak unit for my condo in River North 1 year ago. Oasis completed the 1 year service as well. All of the services that Oasis provided were excellent. This includes system knowledge, system installation, office notifications for progress updates, check-ins for satisfaction responsiveness and price. If you need a new system, system repair or annual system service Oasis is your best choice!

The Oasis crew replaced our HVAC system including AC compressor in just over half a day. They did a fantastic job - delivered what was promised - install looks neat and tidy. They had to get the AC compressor onto the roof of our 3 story building. The crane operator they used was quick and professional. I would recommend Oasis for maintenance and installs of HVAC systems. Great company to work with!
