Just saying hi to everyone and introducing myself. I'm a service tech, been in the field for 10 almost 11 years. I've serviced and installed gas furnaces, heatpumps,boilers,geothermal. I have my journeyman license and was just poking around looking for info on a Lennox I was servicing tonite. It's a whisperheat, I haven't messed with many Lennox brand equipment so just was confirming what I was seeing tonight.
