Extreme markups, laughable "egg logic," and an owner who calls clients a "big baby"…read more If you enjoy waiting two weeks for service, getting charged a $165 markup on standard retail products, and being called a "big baby" by the owner when you ask about it--then this is the company for you. Otherwise, take your business literally anywhere else. To be fair, the field techs (Shane and Joe) were good guys who did their jobs well. But the owner, Greg, is an absolute nightmare to deal with. Here is how my experience went: The $165 Markup: They charged me $425 for an off-the-shelf ecobee smart thermostat. The exact same unit sells at major retailers like Best Buy for $260. I waited two weeks for them to show up--time I easily could have used to buy the unit myself if I knew he was going to tack on a nearly 64% markup for a product in a cardboard box. The Laughable "Egg" Logic: When I texted Greg to question the massive markup, his attempt to defend it was unintentionally hilarious. He actually wrote: "When you go to the grocery store or a restaurant and you order up three eggs and they charge you $10. Do you tell them I could buy a dozen eggs for less than that?" A factory-sealed, mass-produced thermostat is not a cooked meal at a restaurant. Comparing a retail piece of consumer electronics to three scrambled eggs is pure comedy. The Childish Insult: When I called out how ridiculous his "egg" comparison was, Greg threw a total tantrum. Instead of handling a basic billing inquiry like an adult, he dropped all professionalism and texted me: "What a big baby you are." Calling a paying client a "big baby" because they call out an outrageous markup tells you everything you need to know about how Greg runs his business. He doesn't care about repeat clients, reasonable pricing, or basic respect. Save yourself the money and the headache--hire an HVAC company run by an actual professional.

I decided to go with Herchenbach Mechanical after comparing a couple other places in the area. Scheduling an appointment was easy. Curtis and his team came over and installed the AC unit fairly quickly. They were very professional and courteous. Fast forward to a few days ago, my kid decided to throw pieces of chalk down the pipes. I called Herchenbach Mechanical to schedule a time and date that works for me. They will email and text you to confirm your appointment. On the day of your appointment, they will also send you a photo of the technician that will be over. Adam, the technician, was very friendly, knowledgeable, respectful and on time. I told him what happened and he explained what he would need to do to get the chalk out from the pipes. I also scheduled them to clean my AC as well. After Adam finished using the hose from the backyard, everything was neatly put back the way it was. He didn't leave anything out or left a mess. When he was inside the house, he would immediately put on those disposable shoe covers without me having to ask. Herchenbach Mechanical has always provided great, friendly service when I needed them. I have nothing but good things to say about Curtis and his team. Again, highly recommend them! You won't be disappointed.

I am extremely disappointed with my experience with this HVAC company…read more I originally called them because I was having an issue with my outdoor HVAC unit. After looking at it, they told me the unit was bad and needed to be replaced. I trusted their recommendation and paid over $3,000 for the replacement/repair. The work was done quickly, and the system worked fine for about a year. This season, the outdoor unit stopped turning on. I had another HVAC technician inspect it, and he told me the issue was caused by a hole left in the welding during the installation, which allowed the Freon to slowly leak out over time. Because the Freon was completely gone, the repair is now much more expensive. To be sure, I had a second technician inspect it as well, and he gave me the same explanation. I reached out to this company to discuss the issue. They answered my first call, but after that, my repeated calls and emails have gone unanswered. That is extremely frustrating, especially when the problem appears to be related to the installation work they performed. My sincere advice is to be very careful before hiring this company. In my experience, they did not stand behind their work or properly respond when I needed help after the job was done. I am very disappointed with the quality of the installation and the lack of customer service afterward.
