Our recently completed hvac repair projects in chicago

As a home or business owner, nothing is more important than making sure that your heating and cooling systems are in the best condition possible. When the temperature drops in the winter, you need your home to be warm and cozy. When the summer months bring hot air in from outside, you need a great air conditioner. At A Custom Services, our HVAC repair specialists in Chicago provide the best furnace and boiler services in the area. We also offer air conditioning and radiant heating installations and repairs. 

Furnace Repair Services

Staying up to date on maintaining your furnace is vital for its health. When a furnace is not well cared for, it tends to break down easily, especially when it’s winter and you need it the most. When it gets too cold in your home or office, it makes everyone uncomfortable. That’s why our HVAC company offers quality furnace repair services in Chicago. We understand the inconvenience of having a broken furnace, and we will work tirelessly until your home or business is warmed up the way it should be. 

Boiler Repair Services

One of the best ways to reduce energy costs in your home is to invest in a high-efficiency boiler and keep it well maintained. Getting a high quality boiler can lower the amount of gas your home consumes by approximately 20 percent, leading to cost savings of at least 10 to 30 percent. Contact our team to learn more about the boiler repair services we offer in Chicago.

AC Installations

During the summertime, there’s nothing like walking into a well air conditioned building. However, when your air conditioner gets too old or clogged with dust, it can stop working at the worst time. Our HVAC repair and AC installation contractors in Chicago are experts in repairing cooling systems. Whether you would like to schedule a short maintenance appointment, or if you need a full installation service, we stand ready to help you.

Call our Chicago based HVAC repair technicians today to get started! We’re excited to meet you, and help restore comfort to your home or business.

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.
