Wondering when to call for heating repairs? Sometimes, it’s easy to notice when your heating system or furnace breaks down. You want to get help anytime your heater stops working or fails to keep your property warm. However, it’s also a good idea to contact a heating repair technician if:

  • Your system blows insufficient heat
  • The heater cycles on and off frequently
  • The heater makes strange noises or produces an odd smell

The above warning signs indicate that you should contact a heating repair specialist, even if your heater is technically working. Quickly getting help can allow technicians to repair your heater before it fails completely, leaving you exposed to a chilly Chicago winter.


Proper maintenance may help you avoid a heater or furnace breakdown. Our team provides comprehensive heater maintenance services to ensure that your system keeps working correctly with limited issues.

We schedule regular maintenance checks for all heating systems. If you have a regular furnace, you may want to set up a maintenance visit in the late fall before temperatures start to drop. Maintenance visits allow technicians to identify problems before they become severe.

Our team also takes care of HVAC system maintenance. An HVAC system can heat and cool your house or business. Because these systems do double-duty, you may want to schedule twice-yearly service appointments to keep them in excellent shape.

You can also reach out to us if you want to install a new heating system.


Contact A Custom Services for heater repair in Chicago. We repair all makes and models of furnaces, heating systems, and HVAC systems. Just call us at (773) 593-8175 or complete our online contact form to schedule your appointment.

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.
