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.

As a homeowner, it’s important to know when it’s time to replace your air conditioner. When an air conditioner is not maintained regularly, it can age too fast, making it work less efficiently. Air conditioning units that are well cared for can have a lifespan of up to 15 years. To ensure that the cooling system in your home works correctly, contact us for air conditioner repair services in Chicago. Air conditioner installation services are also offered by our team. If you’ve noticed unexplained spikes in your energy bills, it could also be a sign that you need your air conditioner serviced or replaced.

When cooling units get packed with dust, they can stop working as efficiently as usual. Not only can a malfunctioning air conditioner make your home too warm, but it can also cause health problems for your family, as it circulates unclean air throughout the house. The longer you wait to repair your cooling system, the harder and more expensive it will be to repair it. If you notice any signs that your air conditioner is malfunctioning, call our Chicago based air conditioner repair and installation company immediately. Our team of experts is experienced in identifying and resolving HVAC problems quickly and professionally.

WHAT TO DO BEFORE YOU CALL

Before you contact us, there are a few things you can do to help us understand how we can best serve you. First, be sure to check your circuit breaker to see if it’s flipped over or if it has a faulty fuse in it. It is also important to check if the thermostat is registering your home’s temperature correctly. Another reason why your air conditioner is not working could be that it has a leak and is low on refrigerant. The best way to ensure that your cooling system is working properly is to call our air conditioner repair specialists in Chicago. Our friendly team is highly trained and qualified to tackle any issue that may arise. We know you’ll be satisfied with our service.
