I definately do not recommend Bridges Mechanical he lied to me about important safety info.sold me a discontinued furnace without asking me first.no sooner had furnace installed started disecting it saying this maybe wrong and that maybe wrong I stopped him before he replaced more parts in furnace as it was he replaced main board to no avail.the only diagnostic tool I seen was a thermometer he picked up off road and glued it back together he told me himself.furnace was installed in Oct no heat untill late nov.i had to get another company to get the junk working,!!!!I really regret hiring this bridges Mechanical!!!!in my opinion save yourself the expense and the lies and hire a reputable company!!!!
