I was really pleased by the process for getting our AC replaced. Matt worked with me on a bid for…read morethe new unit in October, and spoke intelligently about the options, where other companies did not seem as educated on the components. This bid was actually less than the competitors, and they had not been around as long as Harster! It was an easy choice. We scheduled to do the replacement in January. Jim and his team came out to do the install and addressed some additional needs to increase the air flow, make the existing unit up to proper code, and make the filter track so it fit filters appropriately. The last unit installation I'm sure was a DIY job or done by a less qualified company. Jim addressed all those issues. I was on a meeting when he was all finished and didn't get to go see the finished product until after he left. It was beautifully done and very neat.

My furnace stopped working and I called Harster after reading the other reviews on Yelp. The receptionist was very nice and she had a technician out in less than 2 hours. I ended up needing a new system, but two of the nicest and most informative technicians came out the very next day and completed the work. They talked to me about the system and what I can do to maintain it. The price was fair and what they quoted originally did not change after the work had been done. I would recommend this company to anyone.

We are preparing to sell out home and I had a home inspection done prior to listing and the inspector took one look at the Sylvania electrical panel and flipped his lid. I was given Charlie McCarty's name from a construction contractor friend and called. He answered and scheduled to meet me at my home the next day. He not surveyed the electrical panel, but inspected each and every outlet in the house. He agreed with everything the home inspector stated in his assessment, and even added a few things that needed to be addressed before St Louis County sent someone for an Occupancy permit inspection. Charlie's computer died the night before his visit, but it did not stop him from meeting me at the agreed upon appointment time. He kept in touch with me as he got his system restored. He sent a crew to the house to handle all the work required after getting the necessary work permits. The proposal was fair (far less than I imagined) and the work was handled in swift fashion. there were a few minor things that got missed, but were corrected with just one phone call. I am not one to gush over people doing their job, but when a small business owner stands up to the job he bids, then stands behind the workmanship and takes full responsibility, I feel I need to let everyone know.
