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.

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.

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.

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 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.

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!

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!
