Cool Z Heating

Always the best, great results at a reasonable price. Been my guy for 10+ years after cycling through for a long time.

I am an elite Yelper. I know good. I know bad. The owner is a genuine businessman and knows the true meaning of customer service His staff, esp Lukasz is amazing and respectful and knowledgeable (I had little ones running around) They installed central air in our old bungalow (we had old school window AC units) I wish I could rate him 10 stars.

We had Cool Z heating service both our boilers on our two flat last year and had him replace one boiler from 1987 this year! He is honest, kind, curteous, and is everything you would want in a HVAC company. Out of the four people we called, he was the second lowest and price matched the lowest quote. As a new hone owner I was out of my element when it came to heating maintenance and he was always available to answer my questions with knowledge and patience.

He respected that this was an enormous purchase for us and I am glad we were recommended him by a friend in the community. I highly recommend him to anyone needing to get their furnace or boiler maintained for the yearly maintenance of cleaning and servicing and should you have to replace a boiler, give him a call and get a quote. I don't think you will be sorry. Maciej, if you read this, thank you again for your hard work today and I am happy to give you a rave review!

I have a wall space heater, and they said they worked on them so I scheduled an appointment. First, no one showed up at the specified time. I called back, and whoever answered the phone agreed to swing out and take my furnace cleaning appointment. He looked at my furnace and told me I needed a new control "because plastic had melted around the control".

I asked for a price, and a follow up to replace it. Never heard back. We went down later to "remove the plastic", and we did not see any material "melted" around the control at all. I would find it hard to trust this business.

This guy and his workers are the best. I used them for several different projects. They replaced an AC unit on my roof. When we had some issues with drainage, he was there within half a day of when i called. He stood by his work and fixed any problems that came up. even if we couldn't prove it was directly related to his work. I gave him keys to my place and he would come and go as he needed to (even when we weren't home). They are very trustworthy and honest/upfront with prices. I highly recommend.

I had scheduled a clean and check at a rental apartment I owned. Coincidentally the tenant had complained the morning of the appointment about the furnace not staying on long enough to heat the unit. When Maciej from Cool Z Heating arrived, I mentioned the issue, and he quickly spotted the problem was a safety switch shutting off the burners because it was in danger of overheating causing damage to the internal components.

So the furnace was continually firing up, then shutting off to cool down, but would never sufficiently heat up the unit. After doing a thorough check of the components and some testing including checking out the duct work, he determined the furnace wasn't getting enough return air--the contractor who had done a gut rehab of the unit and installed the furnace didn't provide enough return vents.

The best solution would have been to redo the duct work but that would have been quite costly. Maciej then presented me a few other options that would resolve the problem with one being creating a return vent directly on the furnace. After finishing the scheduled clean and check, we set a date to do the repair about a week later. That did the trick and the furnace has worked fine ever since including through the brutally cold 2013/2014 winter.

I called at 8:45 on Friday afternoon because my furnace was not working when I got home. I was surprised when someone answered, he was pleasant and ready to help me. Wow. I couldn't have been more surprised. I could not have been more impressed. Good job.

I called around noon and we scheduled an appointment for the next day. That was great as it was a hot August day in Cicero, IL. I did ask in case they could come later that night and they said it was hard to schedule a same day visit but they'd try. Impressive communication, I must say. The visit was to the point, Mark asked about the problem and proceeded to check the outside unit and within five minutes came to show me a burnt-out part that needed repair.

He said I could buy it myself or he had some in the car. He replaced the part, he cleaned the outside unit, he brought a light to show me the issue in the inside unit and the system was back at work. He mentioned my unit is old and may need to be totally replaced sooner than later; I've heard this before but we're not ready for the investment so I thanked him for his recommendation. Overall, everything went great, it was fast, and the communication from the company is excellent.

My furnace needed repair I was prepared for the worst that will not be fixable, He was honest to show the problem without selling extra parts or new furnace, Will definitely use him next time we need your service, Thanks!

I live in a high-rise apartment - well actually condo because I am responsible for repairs with in my unit. I contracted Cool Z heating come to my condo and unstop my Furnace. I was getting complaints from lower units about a leak that maintenance tracked to my unit, he quickly found the problem with my humidifier. I would request him in the future if I had more issues.

My air conditioning system stopped cooling late last night so I called Cool Z Heating first thing this morning. The service department called me back to tell me they could come out around 1:00 today. A service rep callled again to let me know how the technician's schedule was shaping up, and called a third time to let me know he was on his way. I was really impressed with this level of responsiveness.

The technician arrived about 1:15, diagnosed the problem as a bad capacitor and gave me a price within 10 minutes or so. By 2:30, he'd completed his work and was out the door. I didn't catch the technician's name, but I was greatly impressed with this man who did an excellent job explaining what was wrong and what he was going to do to repair the system. He's a great asset to this company which clearly has customer service at the top of their priorities!

I highly recommend Cool Z Heating for their efficient work and mainly their honesty. I had other company to check on my furnace which had stopped working, and I was told to replace it with a new one and that it's not fixable. I called Cool Z Heating to get an extra estimate and when the guy looked at it, he asked me if we would rather just fix it instead?

It end up to be a small part that he replaced. If I go with other company that time it would cost me much more money. Im sure that happend to many people that as a result of lack of knowledge they were ripped off. And now I have no problems and is working fine, great service!

Not sure about all the negative reviews. My AC blower motor went bad and they were able to come diagnose and replace it the same day even though the guy had to work until nearly 7pm.

DO NOT HIRE THESE PEOPLE WITHOUT READING THIS REVIEW! The motherboard of our furnace shorted and needed to be replaced in the winter. They came out and replaced the motherboard so we got heat but they deliberately broke our AC so they would get repeat business call in the summer. What they did was cut the 24V wire that carries the signal from the thermostat to the AC compressor (on our roof).

These wires rarely "go bad" and its extremely unusual for something to go wrong with them. Sure enough, we called them to fix the AC in the summer and they recommended a very costly fix. We got a second opinion from an electrician friend of ours took off the motherboard and found that they cut the wire (and this is how we know it was deliberate) they recovered the cut wire with wire covering (not just simple electric tape) so you wouldn't notice that wire was cut.

I have pictures to prove it. Our electrician friend couldn't believe the cover up job and said there was no way that could have happened on accident. Do not trust these guys to do any work in your home.

We bought our home three years ago and used this guy to have our tankless water heater installed. It works great, we have had no problems and the price was fair. After our water heater was installed we noticed the furnace wasn't working. Mark came back the next day to re light the pilot. Didn't even give us a bad time for being idiots. This year our furnace needed to be serviced so I called mark again. He came out the next day and charged $69 for the service and cleaning. I would recommend him to anyone. Polite and professional.

This place still sucks. I started using Four Seasons. So much better the Cool Z.

These guys are NOT the real deal. They charged $95 for a service call. The web site says the price is $69. Typical scam by a company that is just out to make a buck and not interested in customer service. STAY AWAY!

Absolutely horrible! We called them asking to them to fix our central ac because it was leaking internally. The person arrived two hours late and cleaned it up. Charged us $150 just to clean the air conditioner. It then started to leak an hour after he had left. We called them back and ask them to come and fixed the leak (again). They promised to come Tuesday evening, did not come.

They promised to come on Wednesday afternoon and I even took time off from work to be there, they did not come. Finally, they came on Thursday and the guy worked on the AC for half an hour. He wanted to charge us for $95 service fee for not fixing what he was suppose to fix last Friday. We refused and he got angry, called the owner and cursed a lot in Polish. Perhaps, they are better with furnaces but I would never use them again to fix the air conditioner ever again. I can only hope that our air conditioner will not start leaking again.
