Working with A Custom Services Inc, including the engineer Steve S. and Michael in their business office, was all positive and I will happily work with them again. They understood, made helpful recommendations, communicated proactively, and they followed through as they said they would. It was a stress free experience and good value for the work.

Alfredo and Tom replaced our furnace and did a Fantastic Job. They were professional, courteous and very informative. They were considerate of the delivery, prepping the area to keep it clean and worked efficiently and very quickly. Alfredo is a master HVAC professional and did a great job! Tom was fantastic on the installation as well as keeping my wife and I informed of the new aspects of the furnace and thermostat. Previous to the replacement Steve responded very quickly for the no heat call and was very professional to diagnose the problem and provide multiple solutions. Steve did an excellent job with the solution write up, planning for the hardware readiness and ensured that our project was completed the next day. Michael in the main office performed all the managerial interaction very well, answered all our questions and took care of the paperwork and invoicing in a very professional manner. Highest grades for this team and I will recommend them to all our friends.

A Custom Service was amazing throughout our experience with them. When I contacted them, Michael called me back promptly and helped me in scheduling an appointment. He also called a day before the appointment as a friendly reminder and to confirm that the appointment still worked for us. Alfredo was the technician who came to our house. He was on time and walked us through everything he was checking. He also answered all of our questions and even answered some questions my neighbor had about his system! He was very thorough, knowledgeable, and professional. After the service, Michael reached out again to make sure everything worked well. We used A Custom Service to do routine maintenance on our radiant heating system, and moving forward we will be using them to address all of our HVAC needs! Job well done.

Contacted A Custom Service to get some work done on my boiler. Response was quick, Michael was able to help me set an appointment up and was very attentive to our communications. Alfredo, our technician, was knowledgeable with boiler systems and was able to answer my questions. Found out that a circulation pump needed to be changed and he had the part in his truck so there was no delay in getting us up and running. A Custom Services will be our go to heating service from now on.

Great crew all around, owners, office, technicians. What I most appreciate is that everyone I dealt with was polite and professional. Secondly, they are trying to solve your HVAC issues, not charge you for things you don’t need. Highly recommend.

Michael was very responsive with initially setting up the service technician appointment. Alfredo was very helpful and a wealth of information. Our experience with everyone at A Custom was superb.


How do you know who to pick to install your AC unit? There are so many contractors in the area, but who can you really trust? 

To build trust with our clients, A Custom Services offers on-site consultations. We like to personalize things. Our AC techs understand what Skokie homes and buildings need in terms of systems that provide maximum cooling. 


Everything has to be designed around the specifications of your property. Every home is unique, and what works for you won’t be the best choice for someone else. Our local AC installation contractors will help you choose between the following:

Central Air Conditioning Systems

Central air is great at cooling multiple rooms all at once. They are powerful and connect right to your already existing ductwork.  

Ductless Mini-Split AC Systems

Does your home not have ductwork? Our AC techs might recommend ductless mini-splits with independent temperature control in each room.

Heat Pumps

Going green and energy-efficient — those are words that resonate with our clients. Heat pumps are an environmentally conscious choice that transfer cool air in an eco-friendly way. 

Inverter AC Systems

Choose this advanced system that adjusts its speed to maintain a consistent indoor temperature.

A Custom Services understands that trying to pick from these options can be confusing. That’s why we offer completely free on-site consultations so we can walk around your property to understand what will best work for you.


Got an older AC unit that’s just barely hanging on? The last thing you want is for it to fail in the middle of the summer. Instead, just call up A Custom Services and ask for a free in-home consultation to discuss your air conditioning options. 

Our AC techs examine your current AC unit and discuss what will best work for your installation. We’ll give you an honest estimate and promise to stick to it. You are our neighbor, and you deserve to be treated like this. 


How much should I expect AC replacement to cost me?

The costs and expenses vary based on the AC system type, what needs to be done during installation, and whether new ductwork is needed. We offer upfront contracts with no hidden fees, so you will know exactly what you will pay before we begin the installation.

What is included with a new air conditioner installation with A Custom Services?

A Custom Services air conditioning installation in Skokie comes with a 1-year satisfaction guarantee. Our AC techs also provide seasonal tune-ups and full inspections.  

Can I install my AC unit without professional help?

A Custom Services never recommends it. Why? Because AC installation can be dangerous. You need to make sure everything is done safely. Plus, self-installation may even nullify your homeowner’s insurance policy. 

Let’s Keep It Cool, Skokie!

You still have some time before the heat hits to install a new AC unit. Contact A Custom Services today for your personalized no-obligation consultation and discover why we’re the trusted choice for air conditioning installation in Skokie.

Every installation is different. Factors such as which unit you choose and how big your house is can affect the pricing. For example, central air conditioning or geothermal systems will cost thousands of dollars, while mini-splits or portable air conditioners, etc., are much cheaper. To know the exact cost for your AC installation, call us to schedule an appointment for a free estimate.

Usually, professional technicians will recommend that you replace both the inside and outside AC units when performing a replacement installation. However, if your AC is on the newer side and still has its warranty, then you can probably receive a new unit from your manufacturer at a low cost. 

Everything. The pieces we install will include parts of the inside air handler/evaporator as well as the outside unit’s compressor or condenser. We also supply you with new refrigerant supply lines, thermostats, condensation pump and drain lines, and whatever other components are applicable. 

A rule of thumb is by the time your air conditioner hits 15 years old, it’s time for a new unit. The AC’s outdoor components are often exposed to extreme temperatures that corrode over time. The best way to prevent damage is to get maintenance on your air conditioner twice a year. This will ensure your unit has a longer lifespan.

No. It is dangerous to try to install a new AC unit on your own. It is important to always call a professional HVAC company that has the right experience and equipment to properly remove your old unit and install a new one.
