"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."
