#1 FOR FURNACE Maintenance IN CHICAGO, IL WITH OVER 30 5 STAR REVIEWS

Did you know that heating and air conditioning systems tend to break down most often when the weather is the most severe? That’s when your comfort systems are under the most stress. This means you are most likely to lose heat in the middle of the night during a nasty cold snap, while your air conditioner is most likely to quit in the middle of the afternoon on a sweltering summer day.

Plus, if your systems are older or you skip regular maintenance, your chances of having a breakdown increase dramatically.

This is exactly why we developed our Preventive Maintenance service plans.

HEATING & COOLING TUNE UPS FOR HOMEOWNERS

Time wears on everything and eventually anything left without maintenance long enough will dwindle. An inefficient heating or cooling system uses a lot more energy to operate. This wasted energy will increase the cost of your utility bills. Not to mention, this type of maintenance can also help to extend the life of your heating or cooling system and cut back on expensive repairs needed to fix inconvenient system malfunctions.

Our tune-ups are completed promptly by our highly experienced technicians. Most HVAC equipment manufacturers recommend a professional tune-up at least once a year. If you need a tune-up for your heating or cooling unit? We can help. Our Licensed technicians can service all makes and models of residential / commercial heating & cooling units.

ANNUAL SERVICE PLAN FOR CHICAGO HOMEOWNERS

  • Emergency service – 24-hour emergency service for no-heat calls, gas leaks and other dangerous situations.
  • Convenient appointments – For early-season tune-up appointments, Service Plan members can reserve the most convenient times.
  • Annual tune-ups – gives you savings and peace of mind
  • Fewer service problems – Our expert tune-ups, for both your heating and cooling systems, prevent expensive problems and inconvenient breakdowns.
  • Savings on heating and cooling bills – You can save as much as $30 per month on summer electric bills and up to 10% on winter fuel bills.
  • Safety – To prevent carbon monoxide poisoning, resulting from a problem with your heating system, we do regular safety and venting checks.

Keep warranties valid. Most warranties on heating and cooling systems exclude repairs that occur due to “lack of regular routine maintenance.” With our Preventive Maintenance service plan, that won’t be an issue. Even small problems with your heating and/or cooling system can take big bites out of your budget. When you have the protection of one of our service plans, there’s a lot less to worry about.

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.
