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!

Timely and knowledgeable technician came to my home, and identified a critical problem in my…read moresystem. Would certainly recommend, but make sure you ask for no techs in training, and double check the solution is to your standards. * The loss of star (1) is because I was charged for (2) techs, because someone in training was along. The trainee did little more than incorrectly place, and then over-tighten my fan blade, which the senior tech wound up coming back to remove. *Loss of star (2) is due to the initial "repair" strategy, being to bypass the high & low safety systems of the unit. It would have operated, but it would have done so until catastrophic failure due to the bypass.

Giving Affordable Heating & Cooling anything less than 5 stars would be dishonest, and I would actually give them more stars if Yelp allowed it. Thanks for all your help guys!

NWI H&A got to us in less than 3 hours and the tech was awesome and had the furnace up an running in about 15 to 20 minutes.

The tech explained what the problem was and gave us advice on how to keep our furnace running well. I am a very satisfied customer.

My family and I pulled into his parking lot so I could walk my son across the street because he was in the baseball parade for portage. My wife was gonna hope in the driver side and drive down to the other end where my daughters team will be. this guy comes out the house scream we can't park here. I said we aren't and tried to explain what was actually happening he's telling me (in front of my son) to get the F out of here. Again I'm trying to de-escalate. his dog run as starts harassing my 2 year old in the car cause the door is still wide open from my son climbing out finally after my wife gets in the driver side I'm trying to get my son across the busy street to get him away and to his group. once I knew he was ok and in good hands I return to see this guy threating my wife with a baseball bat. the coaches had to stop me from going across the street after him. my wife pulled off safely and the cops were called. filed a report and got witness testimonies. If this is how this business handles a simple miscommunication I wouldn't want them anywhere near my property.

The other company told me I needed a new compressor for $1699 and they took only cash. After a repairman ran off with $453 of my aunt's cash, I decided I did not feel comfortable giving the HVAC repairman $2000 (with labor) in cash. So, I told him I would seek a second opinion. I called STI Heating & Cooling who were booked for the week so I made an appointment for the following week. Ted arrived on time and was very professional. He took a look at my unit (which is 42 years old) and told me I needed a Hard Start Capacitor for $173. He also checked the amount of Freon (R22) told me I might need a little. He installed the capacitor and added a little Freon and my unit start blowing extremely cold air. Ted's work was great! He told me his father had an old unit like mines and he keeps him father's unit working. I told Ted the other repairman thought I needed a new compressor and Ted suggested maybe the other repairman was not familiar with older units like mine. I am SO glad I called STI Heating & Cooling! I told Ted they are now my go-to company for ALL my HVAC activities. I would highly recommend this company - they proved to be a huge money saver for me.
