They will hang up the phone on you if you're calling for repairs. Brand New AC that they installed broke down. Still under warranty, and they're too lazy to come out to fix it because "I'm too far away". I guess I wasn't too far to install the unit, but too far to fix the problem they did !!!

They were quick to get the install scheduled and were very professional and courteous through the entire process. Not only that but they set all the rebate paperwork up for us to send out. Josh is quick to answer any questions you may have. After our install we had to have an emergency call for our older AC unit. He was quick to come out and troubleshoot for the problem. I am personally so glad to of reached out to Sub Cooled. They will be our forever HVAC company. If you need someone for a repair or an install I 1000000% recommend reaching out to Sub Cooled! You will not regret it!

For example, having the air conditioning and heat going on at the same time would eventually cause risk of wear and tear the heating & air condition, causing us to have a new unit installed, being professionals that should have never happened. Also, when taking out the old furnace, you used no covering and left pieces of stuff everywhere that they didn't clean up and a mark on my wall that will not come out. Perhaps if the worker concentrated and spent more time on the job rather than being unprofessional, installing the furnace job would have been done correctly in the first place. Approximately we have spent roughly $11,600.00. It's unnecessary getting the service done from this company in the future. We would not recommend this company to anyone.

I was looking to have our boiler system repaired, first technician said it was a bad ignitor, which it was not. Second technician said it was a bad pressure switch, which was ordered and installed. Boiler ran constantly and would not shut down, even after thermostat temperature was attained. Third diagnosis was another switch (since the first one installed was incorrect). After that installation boiler ran constantly, without burners ever coming on. Total incompetence, with no apologizes. $500 dollars later, and still no functional boiler. We called RCM heating who came out that day and had the boiler properly fixed and running within an hour! Do not call JTR unless you want to waste your money! Mr. H

When I asked what Windy City was going to do about it, you said nothing. That's when I got upset.

The fire department was called and we (me, my wife, and our 3 kids) were without heat on a 20 degree night. The following morning I made a few inquiries just hoping to get something scheduled and I was surprised to find they had someone available almost immediately. The estimate fee (only $75) was waived once Andy informed us what we needed, 1 hour later our house went from 65 degrees to a comfortable 74. Thank you so much. I would HIGHLY RECOMMEND them.

Andy did a great job at figuring out what was going on with our furnace, explained the options to fix what was needed, and did the repairs that were necessary. By also figuring out that the gas meter was the issue that needed to be taken care by our gas service provider, Andy saved us so much money on unnecessary repairs because the initial issue was outside the furnace. This is the second time we've used Specific HVAC and I will continue to call them for any future repairs. Andy is friendly and provides quality service.
