Air Conditioning Installation in Northlake, IL

When summer temperatures climb across the western suburbs of Chicago, having a reliable and efficient air conditioning system is not a luxury but a necessity. At Oasis Plumbing, Heating & Cooling, we specialize in professional air conditioning installation for homeowners and businesses in Northlake, IL, and the surrounding communities. Since 1997, we have delivered quality customer service, reliability, and expertise in heating, cooling, and ventilation to our residential and commercial clients. With over 20 years of experience serving customers in Chicago and the Northern Suburbs, we understand the unique climate demands of this region and the importance of getting your installation right the first time.

Northlake sits in a climate zone that experiences both extreme heat in the summer and bitter cold in the winter, making it essential for property owners to invest in systems that can handle the full spectrum of weather conditions. A properly installed air conditioning system not only keeps indoor spaces comfortable during July and August heat waves but also improves indoor air quality, reduces humidity, and protects sensitive electronics and furnishings from heat damage. The U.S. Department of Energy estimates that heating and cooling account for roughly 48 percent of home energy use, which means the quality of your installation directly impacts your monthly utility bills for years to come.

Our Air Conditioning Installation Process

Every air conditioning installation project we undertake in Northlake begins with a comprehensive in-home or on-site assessment. Our highly trained technicians evaluate your property’s square footage, insulation levels, window placement, ductwork condition, and existing electrical infrastructure. We perform a Manual J load calculation, which is the industry-standard method for determining the precise cooling capacity your space requires. This calculation factors in everything from ceiling height and sun exposure to the number of occupants and heat-generating appliances. Sizing a system correctly is critical because an oversized unit will short cycle, wasting energy and failing to dehumidify properly, while an undersized unit will run continuously without ever reaching a comfortable temperature.

Once we have determined the ideal system size and configuration, we work with you to select the right equipment for your needs and budget. We install a wide range of air conditioning systems, including central air conditioners, ductless mini-split systems, and heat pump configurations. Our responsive support staff and technicians walk you through the options, explaining SEER2 ratings, compressor types, and warranty terms so you can make a fully informed decision. The current federal minimum efficiency standard requires new central air conditioners to meet a 14.3 SEER2 rating in the northern climate region, but many of the units we install achieve ratings of 18 SEER2 or higher, translating to significant energy savings over the life of the system.

Types of Systems We Install

Central air conditioning remains the most popular choice for homes and businesses in Northlake that already have existing ductwork. These systems use an outdoor condenser unit paired with an indoor evaporator coil, typically mounted on top of your furnace. We ensure proper refrigerant line sizing, secure electrical connections, and thorough ductwork inspection during every central AC installation. If your ducts are leaking or poorly sealed, we address those issues before commissioning the new system so that you achieve maximum efficiency from day one.

Ductless mini-split systems have grown enormously in popularity over the past decade, and we install these systems frequently in Northlake homes that lack existing ductwork, as well as in room additions, converted garages, and finished basements. A ductless system consists of a compact outdoor compressor and one or more wall-mounted indoor air handlers connected by a small refrigerant line. These systems offer zone-based cooling, meaning you can set different temperatures in different rooms, which is ideal for families with varying comfort preferences. Mini-splits also operate at whisper-quiet levels, often below 30 decibels indoors, making them an excellent choice for bedrooms and home offices.

What Sets Our Installation Apart

We believe that the quality of the installation matters just as much as the quality of the equipment. Industry studies from the Air Conditioning Contractors of America show that improper installation can reduce system efficiency by up to 30 percent, regardless of how advanced the equipment may be. Our technicians follow manufacturer specifications precisely, from brazing refrigerant lines with nitrogen purging to verifying proper airflow across the evaporator coil. We perform a complete system commissioning after every installation, which includes checking refrigerant charge levels, testing thermostat calibration, measuring supply and return air temperatures, and verifying electrical amp draws against factory specifications.

  • Manual J Load Calculation performed before equipment selection to ensure precise system sizing for your property
  • Professional Refrigerant Line Installation with nitrogen purging and pressure testing to prevent leaks and contamination
  • Full Electrical Assessment including breaker panel evaluation and dedicated circuit installation when required
  • Ductwork Inspection and Sealing to eliminate air leaks and ensure optimal airflow throughout the building
  • Post-Installation Commissioning with comprehensive testing of all system components and performance verification
  • Thermostat Setup and Programming including smart thermostat integration for enhanced energy management

Energy Efficiency and Long-Term Value

Investing in a new air conditioning installation is a significant decision, and we want every Northlake customer to feel confident that their investment will deliver lasting returns. Modern air conditioning equipment has advanced dramatically in efficiency and reliability. Variable-speed compressor technology, for example, allows newer systems to modulate their output based on real-time cooling demand rather than simply cycling on and off. This results in more consistent indoor temperatures, lower energy consumption, and reduced wear on system components. Many homeowners who upgrade from older systems report energy savings of 20 to 40 percent on their cooling costs.

We also help customers take advantage of available manufacturer rebates and utility incentive programs that can offset the initial cost of a high-efficiency installation. ComEd and other local utilities frequently offer rebates for equipment that meets certain efficiency thresholds, and we stay current on these programs so we can guide you through the application process. Additionally, the federal Inflation Reduction Act has introduced tax credits for qualifying energy-efficient HVAC equipment, making this an excellent time to upgrade your cooling system.

Customer Reviews

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.

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 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 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.

Nicole U.

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 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.

We'd just moved into our new condo when we realized that none of the three toilets were working properly and a shower was backing up. Oasis was able to get us on the schedule quickly and the technician they sent out was great. Chris was super friendly, efficient, knowledgeable, and best of all, left us with three working toilets and a draining shower. The previous owners had caused a variety of problems to the fixtures and plumbing. Chris diagnosed and resolved each mystery issue. He explained everything clearly and the appointment overall took far less time than I expected.
Response from the owner:Thank you, Monica! We appreciate your kind words and are glad to hear that Chris could resolve the plumbing issues efficiently. If you need anything else, feel free to reach out!

Incredible work by the Oasis team on our water heater and AC unit replacement. We found ourselves with an aggressive leak from an old AC unit and coil. We were without AC in the heat of August while hosting guests with young children. Hani was out immediately to get us an assessment and estimate. We were even able to schedule additional work we had been planning to save time/money. The very next morning Michael, Serge, and Nick were able to replace our rooftop AC unit, completely gut, replace, and rebuild our coil casing, and install a brand new water heater. Incredible work, very thorough explanations of work done, and thoughtful accommodations for young children and sleeping babies. Can’t recommend enough. The kids weekend was saved, thanks Oasis!!
Response from the owner:Ryan, thank you for your fantastic review! We’re glad to hear that Hani, Michael, Serge, and Nick were able to help you with the AC and water heater replacement, especially during such a busy time. Your kind words mean a lot to us, and we're thrilled to have made a positive impact on your weekend.

Oasis responded very quickly and arrived on time early the next day with a same day installation of our air conditioner. You can't ask from r more during the month of August.
Response from the owner:Thank you, Leonard! We're glad to hear that you had a quick and timely installation of your air conditioner. Your satisfaction during the hot month of August means a lot to us!
Oasis heating and cooling, Anel & Vaha were very thorough, efficient, and made sure everything was working correctly. They explained on what they did and provided great information about our new furnace. Updated: Joseph from Oasis came for an AC maintenance. I told him that the unit has been making more noises than normal. He went above and beyond to resolve the issue.
Response from the owner:Thank you for such a nice review and feedback.

I have used Oasis services for about 12 years, and I have always been very happy with the quality of their work and the knowledge and professionalism of their staff.

We had Oasis come out to take a second look at an older AC system, and the experience was great. They were thorough, straightforward about what they were seeing, and took the time to explain the different options without making it feel like a hard sell. I especially appreciated the conversation around replacement, sizing, and what made sense for an older Chicago home rather than just giving us a number and moving on. Very helpful and professional experience.
Response from the owner:Thank you, Mr. Burnett, for your wonderful feedback! We're glad to hear that you had a great experience with our team and appreciated the thoroughness and professionalism in addressing your AC system. Your satisfaction means a lot to us!
