Great company and most importantly - honest. They could have charged me a lot more on a job I called about that turned out to just be cosmetic. Instead, I was only charged the service fee. I would recommend to anyone and will be using them in the future.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. Care was taken to evaluate our home, ductwork, and existing conditions to recommend the right equipment for our home. 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

Our tech Trace, was excellent and never gave up on repairing our AC. That's after another company was out the day before and overcharged the unit with freon. We'll be using them again in the future. Right now we're cool with a string of days in the upper 80s and 90s.Rickread 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

Excellent Experience, I purchased my air conditioning from Herchenbach 2 years ago and the experience was exceptional. The installation process is so professional. When it came time to replace my furnace I only made one call and that was to Herchenbach. Curtis is wonderful to deal with and honest. The furnace installation was handled extremely well. I highly recommended Herchenbach and am proud to refer them to friends and family. I’m very confident you will be highly satisfied with your experience!read more

Herchenbach recently replaced our 27 year old AC and Furnace. We are totally pleased with the exceptional customer service and high quality installation work. The installation team was very hard working and efficient. The installers were friendly and took the time to explain all the features of our new system and high tech thermostat. And before they left they made sure their work areas were cleaned-up and spotless. From the bid/proposal to installation the process was smooth. I highly recommend Herchenbach Mechanical.read more

Herchenbach Mechanical just finished their installation of our new Carrier infinity heating and air conditioning system today, replacing a 23 year-old system.
