What People Say About West Mechanical Hear what our customers have to say!

The two stage fan definitely seems to keep the temperature more stable. We have had to change our settings to a lower temp overall because the settings we used with the last furnace were too hot for the new furnace. I'm looking forward to seeing my next gas bill since this one seemed to double from last November. - Janell   customer
Just a quick note to let you know how impressed I am with your service.  I called you this morning expecting a several days' wait just for a technician to be free to make an estimate, but not only did you dispatch one within a couple of hours, he also found and fixed the problem with my heater right there.  I also appreciate his detailed and friendly explanation of what had gone wrong. You should give Mike J. a raise!  I will definitely call West again in the future. - James G.   customer
I have always prompt and good service from West Mechanical... for 17 years - Shane   customer
