    Thorough Heating System Repair

    Excellent service! We had an HVAC heating issue, and Edgar came out the same day. He quickly diagnosed the problem, ordered the part, and fixed everything once it arrived.... He also showed and explained the issue to me and even checked to see if our system was still under warranty. Very professional, considerate, and thorough. Heater is working well now. Thank you!

    Prioritized Education Over Boiler Replacement

    I wasn't sure if I wanted to replace my boiler. Chano spent a lot of time providing me with information and sending me an estimate with no pressure to ...do the job. I eventually decided to replace it, and Ultimate Hvac did a great job, kept me informed each step of the way during the installation, and they cleaned up nicely after they were done. I will definitely recommend them to family and friends.

    Finished an AC Repair in No Time at All

    Ultimate HVAC was fantastic! Our AC at work went out due to the hot week that we had. We called Ultimate hvac, and they were able to get us ...on the schedule right away. Edgar came out and got us up and running in no time at all. He was so knowledgeable. We trusted him right away! I need to have my ac at home looked at, and I will definitely be calling Ultimate hvac to hopefully send Edgar to help! I always used a different company before....one of the largest in Chicago, but never again. Ultimate hvac will be my go to company from now on!

    Above and Beyond on Mini-Split Installation

    Ultimate HVAC and specifically Chano were wonderful to work with. Chano went above and beyond at every stage of installation of a whole house mini split system.... He is incredibly knowledgeable and always took the time to answer our (many) questions. I highly recommend Ultimate HVAC & Chano is one of the best service professionals I have ever worked with.

    Helped a New Mother During a Heat Wave

    Ultimate HVAC is absolutely the best. My AC died during a heatwave, while having a newborn at home, prompting me to call any and all HVAC company offering emergency ...services. Out of four different companies I called, Ultimate HVAC were the only ones to promptly schedule a same-day service. Edgar showed up 10 minutes before the earliest scheduled time and was professional, knowledgeable and offered expert advice. Our unit needed to be replaced and Edgar again showed up exactly as promised, first thing in the morning. I am incredibly grateful to Ultimate HVAC and Edgar for helping us when we truly needed it.

    Fixed Heating Issue in Just an Hour

    Our heat stopped working in our apartment and the maintenance technician sent by property management could not resolve the issue in the 5 hours they spent at our place. ...We called any HVAC company offering 24/7 service, they answered the phone immediately and had a technician to our place within one hour. This technician was incredibly professional, even wore shoes covers in our place. They explained troubleshooting information to me within 5 minutes of arriving. Then diagnosed the problem and what it appeared the previous technician had made worse within one hour of arriving. They provided an estimate and took notes as well as pictures and video of what the problem was so that we could provide this to our property management. I would trust them to repair our furnace issues much much more then my property maintenance team.

This ensures your new heat pump, AC, furnace, or boiler will always run the way it should.

Our AC Replacement Checklist

  • Correct sizing and equipment selection for your layout and usage
  • Airflow verification and ductwork modifications when needed

Springtime HVAC Tips

Spring in Cook County is mud, pollen, and 40° mornings that turn into 70° afternoons. It’s also when drain clogs and “first hot day” AC failures show up. Get ready for the heat with these springtime HVAC tips:

  • 2.

    Flush the condensate line and check the pump
    Spring humidity and winter muck create clogs that lead to leaks, overflow shutoffs, and water damage.

  • 3.

    Test cooling on a mild day
    You’ll catch weak capacitors, noisy blowers, and thermostat issues before they become an emergency call.
