"Ordered two Goodman furnace pressure switches on 12-2-2010 and had them sent over night express via USPS. These items failed to arrive over night from USPS (not ComfortGurus fault). I contacted ComfortGurus via phone about this shipping failure and they credited my order for the shipping charges quickly and painlessly. Every phone call to ComfortGurus was handled quickly and professionally. In short, If you need heating or A/C parts call ComfortGurus.com and you won't be disappointed."
