He also made sure to let me know when he was going to be walking back and forth from the furnace to thermostat in the living room …which I found very respectful and professional. Easily one of the best service techs I’ve had. Thanks Brian!read more

I don’t recall how I found Herchenbach, but I won’t work with any other HVAC company. Everything about them is painless and in perfect order— from scheduling to getting your system running again without any nonsense we saw from others we tried. In my experience they’ve been honest, ingeniously competent and knowledgeable, and fixed each problem I’ve had correctly and on the first visit. Can’t recommend them highly enough.read more

Our furnace was only putting cold air out on Tuesday night. Woke up to 58 in the house. Called around 1 pm on Wednesday and the lady said that she would have a guy come out that afternoon. Our service technician Trace, checked out the furnace and said he could get the part today or have a technician come the next morning. We decided on the next morning. The next morning at 9am Edgar was here with the new part and ready to install it. Great tech and follow through with making sure that everything was working. I am very pleased with both techs Trace and Edgar. Professional, knowledgeable and great customer service. The technician’s went beyond for us and now we will only use them.This is the first time that I have used this company. We always used Lombardo’s Heating in Grayslake. But Doug retired a few years ago and told us that we would be happy with the new owner.read more

We need to have our furnace and air conditioner surveyed as well as installing two humidifiers in the house we purchased couple months ago. Herchenbach was referred by my colleague who has been a loyal customer for more than 15 years. And I know why now. Out of all companies we worked with in the last 20 years, the technicians in Herchenbach are just just absolutely phenomenal. They are professional and extremely pleasant to work with. They did not try to sell us anything and just gave us the facts with explanation. In fact, there was a lot of complication with our furnace. They had to send additional help to sort out the complex issue. Not only they did not charge us extra, but also they took time to explain to us the issues and how to maintain the furnace and humidifiers. We are 100% certain we now also became the loyal customers. The technicians we worked with are Jonny Reyes, Brian Dorantes, Brian Yetsky, and Trace Mathiesen, all fantastic to work with! And that, tells you a lot about the company!read more

Herchenbach is honest, knowledgeable and professional. I had them check out my furnace because a different HVAC company, the ones with the lime green trucks, told me my furnace had failed and it had to be replaced. Herchenbach checked it out and there was absolutely nothing wrong with my furnace. I immediately switched from the lime green truck HVAC company to Herchenbach!!!

I am most impressed with the speed with which the company responded to me. I found out yesterday morning that my 26 year old furnace is dead and my house was ice cold. So I called Herchenbach at 8:45 am and within two hours Curtis, the owner, appeared at my house to discuss the estimate as well as see if he could try to repair my existing furnace to get me some heat. When the old furnace did not respond, then his office arranged with their existing customer with non emergency needs so they can let me take their installation appointment so I can have heat ASAP.They take pride in their work and are interested in providing comfort to their customers as their foremost goal. They represented trusted name brand such as Carrier and even arranged financial payment plan through a bank if needed.A day later, I am already in my home comfortably. It took less than 24 hours to solve my heating issue.They showed up on time, cleaned up after themselves, explained their finished work and the whole process was most impressive.I would highly recommend Hirchenbach.read more

We set up the original appt was set for between 2:30 -3 pm. Kool no problem. Then a received a call saying they will be here 2 hrs sooner then originally scheduled. Awesome. When Trace arrived, he was very pleasant and professional. As he was trouble shooting the furnance, he was explaining each set he was doing. Trace found the problem and repaired the defective part. I would recommend Herchbach Technial to do your heating and cooling needs. I would ask for Trace to be your technician to fix your heating/cooling issues. He is very kind, courteous, professional and extremely knowledgeable.Thank you Trace and Herchenbach Technical for your professional serviceread more

My furnace would run on high and the exhaust stunk. They told me that usually indicates a bad heat exchanger. I told them the gas valve was intermittent. They replaced the valve shortly after they left it shut down could run on high. The came back the next day and tested for the heat exchanger and said it was bad so I need a new furnace they said they could install one tomorrow if I wanted one. They told me about four year 0% financing. I applied for it and was approved for only $7,000 and needed $12,000. They said that they would see if they could help me. They were able to get to $9,000 so I borrowed $2,500 and told them to replace it. They saved my life after removing the old one the heat exchanger was rotted with holes. They still can't figure out why I wasn't carbon monoxide. They did great work and worked very hard. I enjoyed watching them and talking to them. I recommend them to every one they all are very smart and can fine problems.read more

I found Herchenbach Mechanical when comparison shopping for a new furnace. The excellent reviews and promotional free quote prompted me to go ahead and schedule a quote. Curtis was quick to schedule an installation quote and was incredibly clear and comprehensive when going over our existing system and what would be expected with a replacement. After reviewing I decided to go with Herchenbach due to some modest cost savings and their standard of a 3 year labor warranty as compared to a 1 year labor warranty from my prior/other HVAC service provider.My new furnace installation went great. Nick and the install team were awesome. They had the whole job done in about 4 hours (super quick in my experience) and even repaired/replaced a drain line that I opted to not to address from the quote as a courtesy. They were efficient and tidy, and the new furnace looks and runs great. I am happy to recommend Herchenbach and will be checking with them when it comes time to replace my AC. Thanks!read more

I called Herchenbach right before a holiday weekend and in the midst of a nasty winter storm to report that my furnace wasn't working properly. Trace came out that afternoon and diagnosed the need for a new furnace. He got the old furnace running and showed me how to reset it if it continued to go off. Curtis was in contact with me throughout the holiday weekend to make sure I was managing and getting enough heat. The furnace started to struggle and Ken came out on the holiday to get it stabilized once more. New furnace was installed by Ken and his crew the next day. Not what I wanted to be dealing with over the holiday, BUT it was handled so well by all involved. I can't say enough about this company and how well they have cared for me over the 25+ years I've used them.read more

We contacted Herchenbach at the recommendation by our neighbor when we had problems with our air conditioning. The technician identified the problem and resolved it for us.

Trace was extremely knowledgeable, patient and personable. He answered all our questions and took the time needed to get the app working on our phones.

I wasn't happy when my "antique" furnace "crapped out" in sub zero temperatures about a week ago, but in under 7 days, we went from making the initial call to Herchenbach, to getting our new Carrier Furnace installed yesterday. It was an unbelievably simple process from start to finish. I got 3 quotes sent over via e-mail the first morning, they were all explained to me thoroughly by Curtis, as HVAC is definitely not my thing, and I chose one of the options that same day, applied for the financing on their website immediately following, was approved 10 minutes later, and they were out here 4 business days later doing the work. Hilllary in the office was fantastic, she remained patient with me, considering all of my questions, as I was nervous about spending the money suddenly, but they could not have been better as a team. The 2 installers were great as well. With the snow melting, I was worried about mud, but they laid down tarps from the entrance all the way downstairs to the furnace room. It was a total non-issue. They got the job done, extremely professional, answered any questions I had with knowledgeable answers, and including demolition, complete install and testing, in 6 hours. It was unbelievable. The Carrier system is so quiet compared to the unit they replaced, and the smart thermostat is so cool as well. Anyway, I would highly recommend Herchenbach and Carrier to anyone looking for a new Furnace and/or A/C system. They will be back out in April doing my A/C system. Looking forward to it! Keep up the good work.read more

I called and they were so helpful. Mike showed up within minutes! He was on his way home when he was dispatched and turned around and came to my house to help us with our furnace. Very nice and knowledgeable. Very reasonable price, too. I hate being over charged and I'm glad I wasn't! I will recommend this company to my friends and family.read more

Our longtime HVAC guy retired and sold his business to Herchenbach. The transition for me was no problem as I have known Dennis and Sharon Herchenbach for years. Our 17 year old furnace died on the coldest day of the winter. Everything about installing a new furnace was smooth sailing. The tech was friendly, knowledgeable, thorough, and quick. Very happy with the price and entire process. While I will miss our retired HVAC guy, I am looking forward to working with Herchenbach going forward.read more

Honesty and Integrity exemplied! We were without heat and had been deceived by a company with which we had been long time customers. We did not have any history with Herchenbach but had seen their trucks locally. We explained our situation and we were prepared to buy a new furnace. After consideration, we were advised to call a local certified Lennox dealer because the broken part of our furnace should be under warranty. They unselfishly recommended a different company. This act of honesty, integrity and unselfishness saved us thousands of dollars. I was not a customer and they did this for me! I can only guess what they can do for their current customers.read more

My furnace went out early morning January 20th. On my daughter's recommendation (who had her furnace and A/C replaced by Herchenbach a year ago), I called Herchenbach, and they came out the same morning. They told me my 23 year old furnace (A/C same age--both original in this house) needed replacing, explained options, and gave me quotes on site. After accepting one, they came out at 7:30 AM the following day and replaced furnace, A/C and humidifier by 4:30 PM. They were extremely polite, efficient and did a complete clean-up after completion. They also thoroughly explained any differences in operation with new equipment compared to the old. I would highly recommend Herchenbach.read more

We have used Herchenbach for a number of years. We needed a new furnace and air-conditioning system and stayed with Herchenbach to replace the old with the new. The two installers were prompt, efficient, courteous, and without a doubt the very best ever. They fully explained everything on the walk through. The clean up, by them, was excellent. I can not recommend this company any higher, except to say I would give them more than five stars if I could.read more

After working with Herchenbach staff to determine the right unit and good price for replacing our aged furnace, they quickly gave us an install date. Technicians showed up on time and did a really nice job of correcting a few errors from the original installation and reworking piping and duct work to provide maximum efficiency from the new unit. They were polite, careful to maintain social distance and mask usage, and were careful to avoid scratches when moving heavy equipment in and out. I recommend them highly.read more

My AC went out in the middle of a heat wave. I called Herchenbach. Laura was kind enough to give me a same day appointment. Service Tech Trace arrived promptly. Trace quickly diagnosed and repaired my coolant leak. I’ve had a service contract with Herchenbach for over 10 years due to their continual responsiveness in caring for my needs. Sharon and Dennis Herchenbach built an outstanding business over many years. Now the reins are being turned over to the next generation, Curtis and Lauren, who will undoubtedly continue to modernize and successfully grow the Herchenbach brand.read more

We were so pleased with the responsive and professional service from Curtis, crew, and admin staff on the installation of our new furnace and A/C systems.

The project was more than just a sale - which is what I felt the competition was offering. I would highly recommend Herchenbach!read more

Noticed that my AC was not pushing out any cold air. Called and made appointment for them to come out and take a look. There was a leak said he could fix it but could not guarantee how long it would last. We decided to go with a new AC and furnace at the same time. Tres gave us a quote and we were satisfied so signed the contract. Before he left we had the appointment for the install date. They they showed up on time and completed the job in about 3 hours. They also ran the extra wire from the thermostat to the furnace to install a smart thermostat. So far we are very happy with the new units and would recommend this company to others. They know how to take care of peopleread more

I have a very old Air Conditioner and Furnace and knew they needed to be replaced soon. I called ABC first and they told me my Compressor failed and that would be just about as costly to repair versus replace. I had them quote to replace the furnace and the air conditioner. I learned that you should always get a few quotes (No matter the situation). So I called Herchenbach (Mike?) to get a second quote on my air conditioner and furnace. The tech (actually the sales guy) came in and starting writing up the quote based on the details ABC provided me. The Tech from Herchenbach (Mike ?), on a whim asked me to turn on the air conditioner. When I did, he looked at me and asked if I would be interested in fixing it versus buying a new. Of course I agreed. Just by hearing the Air kick on, he had a hunch ABC didn't diagnose the issue correctly. He went an got his tools and retested the system. It turn out that I blew a the cylinder, not the Compressor. I fixed it for $176 instead of 5,000. He completed the quote to replace both my Air Conditioner and furnace and the quote came out to be substantially less than what ABC quoted. Herchenbach was extremely knowledgeable and I felt the company will go over and beyond to satisfy their customer. I will be replacing my furnace and air conditioner this fall and Herchenbach Mechanical Inc. will be the company I trust to complete the installation. They are amazing!!read more

Met with Curt Herchenbach who assessed my 32 year old furnace with respect to issues that had developed over the years. We picked out the right furnace with a two stage blower to alleviate the lack of airflow on the second floor. Ron and Matt installed my furnace, were.considerate of my home and courteous to me. I had some issue with programming the new thermostat and the company sent over another employee who knew the most about the thermostat and set it up for me in 5 minutes. Well done Herchenbach Mechanical! I’ve already recommended them to a neighborread more

I had an outstanding experience with Herchenbach Mechanical's installation of my new furnace, air conditioner and humidifier. They also added zoning to resolve temperature variances in several areas of my home. I was on a tight time schedule to replace a 18 year old system that had quit working and they promptly came out to assess my situation and amazingly had a comprehensive quote back to me within hours that included three options for the furnace and air conditioner and two options for the new zoning solution. An out of town trip made it necessary to do the installation as soon as possible and they were very accommodating, starting the install within 48 hours after I gave them my approval. They earn my 5 stars for responsiveness, comprehensive options presented, price/value, product knowledge, and everyone that I interacted with at Herchenbach was very professional and pleasant to deal with. I am very happy to be a new customer and highly recommend them!read more
