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.

Expert AC Repair in Glenview, Illinois

Knowing when to service or replace your AC unit can save you time and money. Well-maintained units can last up to 15 years, but neglect can lead to premature aging and inefficiency. Therefore, if you notice spikes in your energy bill or reduced cooling performance, it’s time to call our air conditioning company in Glenview, Illinois.

Air conditioners clogged with dust lose effectiveness, making your home uncomfortably warm and potentially circulating unhealthy air. Don’t let minor issues escalate into expensive problems. If you spot any signs of poor performance, contact us immediately.

Why Do Air Conditioners Break Down?

Even the most robust air conditioning systems are not immune to wear-and-tear or occasional breakdowns. Many reasons could lead to your AC unit not performing optimally. For instance, inadequate maintenance, like neglecting to clean or replace filters, can lead to system inefficiencies. Furthermore, mechanical issues, such as worn-out fan belts or malfunctioning compressors, are another common culprit. Additionally, refrigerant leaks or electrical problems can cause your system to struggle. 

Understanding these common issues helps in quicker diagnosis and repair. When you encounter such problems, remember that we’re your go-to air conditioning contractor in Glenview, Illinois, available around the clock for immediate assistance.
