I previously worked with another company to replace my furnace. The first company was extremely flakey and would constantly cancel my appointments or simply not show up. Eventually, I decided to go on Angie's List, and I found Siefert Mechanical. This company was extremely quick to get to my house, give me an estimate, and then perform the service. Not only did Siefert Mechanical quote me a price that was $600 less than the first company, they also never cancelled or missed an appointment. They came out once to give me a quote, then the very next time they came out to my house, they replaced my furnace. The quality of their work is extremely professional, and I would HIGHLY recommend this company for any heating/cooling service you need performed.

I was expecting some additional diagnostic fees, and or parts to fix the problem. He was most honest, and up front. I would recommend them to anybody!! Thank you so much for your help!!!!

I hired Chad to install central AC during a big renovation project at my house. The installation went smoothly, he came back with a very fair price vs the other estimates I received. I had a lot of issues with my contractor and Chad had to deal with some things that I feel weren't fair to him. But he handled it awesome and I am so grateful. Reaching out again for additional work this year!

Great! I had other well known companies out to give me estimates and clearly I was not given a reasonable estimate! I didn’t feel I could trust their estimates. With Chad and his company I felt very confident that I was getting a very reasonable estimate. Besides the cost being almost half of the other estimates! The job was performed quickly and professionally! This is my go to company.

Great contractor. Our condenser unit was seating too low on the ground and was getting dirt all over the bottom of the unit. Siefert Mechanical came over and raise the unit up for us. Mr. Chad Siefert and his crew were very professional and punctual. Great communication. I love Chad's genuine willingness to have the job done right providing suggestions and solutions that were perfect for what we needed done. Thank you!!

Chad was excellent with my elderly mother. He kept her informed of what was going on at all times. He also gave her several options rather than trying to push her into the biggest and most expensive units. Very impressed!!
