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.

The technician takes the time to really clean and vacuum our units and explain everything that is going on.

Very good service all the way around.

But that contractor was unavailable when I had a recent furnace issue, so based on a recommendation, I called Arctic. They were busy but told me that they would make room for me that same day. The service tech who came out quickly diagnosed the issue--it resulted from an install error by my original provider. He got the job done and we had heat again before we turned in for the evening. His explained everything he did, and the hourly rate was very reasonable. Honest work at a reasonable price is not easy to find. I trust these guys. And they do warranty work too.

After buying our first house, we learned the entire HVAC system and ductwork needed to be replaced…read more We called several companies but all of them quoted us crazy prices and told us it would be months before they could start. Then we were connected with Adam at Zima HVAC. Not only did he show up the next week, he got the entire job done in just a few days at a fraction of the cost. The quality of work was top-notch and Adam took the time to ensure the system fit our vision, unlike other companies that just wanted to push their agendas. If you're in need of any HVAC work, I can't recommend Adam and Zima HVAC enough. 10/10 - drop everything and call them now!
