Have you ever been truly satisfied with a heating and air conditioning contractor you used? Probably not! Could you still see dirty fingerprints, greasy parts, or areas that should have been cleaned up? Did you have to waste most of a day because they were late or didn't show up at all? Did they charge you a high price - and need to come back and finish or do it over again?We are one of Chicago's top performing service and repair company and we believe "Home Owners" are tired of wasting their time with contractors who don't show up, have to make multiple trips to get the job done, and poor quality workmanship: You shouldn't have to wait at home all day for service.

My furnace quit on me on one of the coldest days of teh year. A Custom Services came out that same day, assessed my situation and was back 1 day later to install a new high efficiency furnace. The professionals who installed my new furnace were polite, competent, answered all my questions and cleaned up so that I didnlt even know they had been there. Great company.

A Custom Services are my go-to partner for HVAC needs. I have used them for years and find Tom's responsiveness and professionalism to be differentiated. Alfredo has been a great technician and always is professional, efficient, and considerate when in my home. They helped me out in a jam and walked me through my options for a new heater, and took care to prioritize us given the cold weather. I am a loyal and happy customer and would recommend!

My experience with A Customer was excellent! From the initial phone call inquiry about needing a new Central Air conditioning unit, through the consult appointment and final work, I was impressed with the professionalism. Alfredo was reliable, honest and went above and beyond in installing a coil in a very tight space and explaining each step of work along the way.

I have used A Custom Services for many years for annual maintenance. Due to ice damage a few months ago on my AC condenser, I needed to get my whole HVAC system replaced, particularly in light of it being very old. Steve did a great job of explaining what I needed and worked with me to coordinate with my insurance company while still getting the job done as quickly as possible. Alfredo and Tommy did the installation work.
They were so neat and quiet! Since we are working from home these days, we appreciated Alfredo and Tommy's careful, professional work. They got the job done with minimal disruption to everything else going on in the house. Would definitely recommend A Custom.

Tom was recommended to us by our home inspector when we purchased our new home. Tom was very knowledgeable and provided an honest and thorough estimate, even returning several times to make sure he understood the extent of the problem so that he was able to give us a thoughtful recommendation and price quotes. He was able to replace our water heater and vent it via a duct on the side of the house rather than our chimney, which we noticed had some condensation. Tom's team was respectful and experienced.

A Custom has been there for us as our go to mechanical contractor. Tom is a well seasoned professional with the experience and knowledge to handle every situation we put in his plate. We are builders and definitely recommended A Custom to anyone who wants a professional contractor with the skills to do a start to finish job with no headaches. Thanks A Custom, for the years of great service.

I had a great experience with A Custom. My home inspector recommended Tom for being honest and good at what he does. I took my home inspector's advice and reached out to Tom and the entire process was seamless! We went from having a consultation one week, to getting quotes and options the next week, and the entire installation done by the end of that week.
A Custom has a great team of technicians who completed our entire furnace, water heater, humidifier and AC installation in one day. You were kind and accommodating. We are grateful we did business with you! Thanks again.

Tom is awesome! A contractor working next door damaged my AC unit this morning. The AC is for a unit I Airbnb with guests checking in this afternoon. He was able to get Alfredo to come service my AC unit and verify it is operating properly before the guests arrived. I will definitely use Tom and refer him to others - outstanding response time, great service!
