Siefert Mechanical - Heating & Cooling

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.

Everything was done in a timely manner. The job was done at a very reasonable price. Chad and his helper Nate were both very knowledgeable and professional. I would highly recommend you using Seifert Mechanical for all of your HVAC needs!!

Great experience. I would recommend to anyone.

Awesome Chad and his guys were polite professional and efficient I would recommend him to anyone

Went amazing without a hitch. Great people over there and Chad treated myself and my home with great respect and sense of family! Definitely recommending to others!

They did a great!! Job!!! I told them what my furnace was not doing. He immediately knew what the problem was. Fixed it fast with out any additional charge. 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!

Excellent service! Showed up on time and completed work even faster than I though. I would highly recommend!

Amazing job done he put registers in my basement and cleaned everything up and came in under estimate will have him doing all my HVAC work

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 amazing to work with. He was flexible and able to work around my schedule. We have had our air conditioner, hvac and hot water heater all installed by Siefert Mechanical. I highly recommend to anyone looking for a reliable, knowledgeable and honest company!

We had Chad install a new system in our home and we are very satisfied with his work. He is very professional and detail oriented..Would highly recommend him to anyone.

Chad did a great job and did it quickly along with the area was clean when he was done. Great job Chad

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!!

Chad was on time. Very pleasant. Completed the job in a timely manner & cleaned up.

Very smooth and a clean professional install. No hidden costs. We are very happy with our new A/C unit.

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.

Extremely professional and helpful, diagnosed and fixed the problem timely. Would definitely recommend and use again.

Chad’s service was great! He’s a pro. Very knowledgeable and informative with his craft. He let me know all the things to look out for and to keep up on to keep things running smooth.
