I recently called Mechanical Man out to fix my furnace. I was told they were pretty busy for the day already, and that they would call back and let me know if they would be out later in the afternoon that day, or first thing the next morning. They called back just before noon and said the technician would be here in 20 minutes. He got it up and running quickly, even with going to get the part needed. Best part, what he quoted me is what I actually paid, it included taxes, and no hidden fees! I can not recommend them enough.
