He was over quickly and had my furnace up and running. I would, also, say he is professional and friendly. I would definitely recommend him to anyone. I've seen a couple of low ratings, but they were for services other than HVAC. Based on my experience and that it is Jerry's Heating and Cooling it makes me wonder of those people are putting their review on the wrong business. On Google Jerry's Heating and Cooling has 100% 5 star ratings with 138 reviews.

Discovered I didn't have ladders to reach the areas needed nor was I warm & fuzzy about going up to the roof peak either. Enter Jerry, I saw on yelp that he was recommended, he came out same day, was very personable , did a nice job, price was reasonable. I also discovered that thru discussion that Jerry and I had a few mutual acquaintances and some things in common. Nice guy, I do recommend him & its highly likely he will take care of ur issue on the same day as his van is well stocked w/ things he needs to do the job on the spot.

As a fellow small business owner, I feel obligated to warn others about our experience with this…read moreHVAC/R contractor. Over more than a decade of managing vendors, this has been hands down the most disappointing and unreliable company we've dealt with. We initially entrusted them with all our heating, cooling, and refrigeration needs. Unfortunately, what followed was poor communication, subpar service, and a complete lack of accountability. When issues came up--which happened frequently--they were more interested in deflecting blame than fixing the problems. Over a year, they raised our service rates by 25% without any notice or explanation, and when I reached out to ask about it, they never responded. I also requested several quotes that were never provided. As a busy business owner, I shouldn't have to chase down contractors just to give them our business. Even worse, they billed us for services that were clearly not performed. I verified this myself--twice--and one time had to bring in a third-party HVAC tech to confirm (with photo evidence) that a rooftop unit hadn't been serviced as claimed. Despite being presented with clear proof, they refused to acknowledge or resolve the issue. After nearly two months of delays and rescheduling for a correction that never happened, we finally hired another company to finish the job. Their refrigeration work was even more troubling. They miscalculated and mis-sized a walk-in freezer, resulting in a system we had to completely replace. They relied on bad measurements and passed critical sizing calculations to a supplier instead of doing it themselves. Even when I showed them accurate specs from the equipment manufacturer, they pushed back with excuses instead of taking responsibility. To make matters worse, they submitted a bid to replace our walk-in cooler and freezer with dimensions that were entirely off. Had we accepted the quote, the units would've physically not fit the space--basic measurement errors that would have led to a major installation failure. The most aggravating part of all this has been their tone: dismissive, defensive, and utterly lacking in professionalism. If you're considering this company, I urge you to think twice. When things go wrong--and they very well might--you'll be on your own. You deserve a vendor who respects your time, your business, and takes pride in getting it right.

Unless you want a poorly-installed system that keeps breaking down and leaves you without cool air on the hottest days of summer, don't use CRS Mechanical. My Daikin is 5 years old and I have had them out every year since it was installed. The Daikin was replacing an old Sanyo AC that ran for 20 years without needing repair. CRS has come out multiple times, charging me hundreds of dollars for each visit, but my unit STILL is not functioning properly. CRS has not followed up on commitments to complete the promised work (e.g., coming back to confirm leaks, etc.) CRS was a BAD choice! (I live in Joliet, but I'm posting on my son's Yelp account.)

Also, we have two HVAC systems in our home and both appear to be undersized. I will be getting an estimate to upgrade both systems, as well. Roger is very friendly and does great work. He's responsive and very easy to deal with. They were referred to me by a friend, who trusts them as much as I now do. I had a horrible experience, with a different HVAC contractor, about 12 years ago and it's nice to now have a contractor that I can trust. Having trust in a contractor is important, and they've earned my trust. I highly recommend them!

Harmonic Heating and Air Conditioning is the BEST!!! Our AC…read moredied and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends.

I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!
