I just wanted to give a big thank you Mark and Stephanie Custis for coming out last weekend to get me set up with a buffer tank and to give my trusty little Climatemaster TZ22 a once over. I learned more about Geo units and plumbing in the hours they were at my house than I have learned in the year of ownership. We got the tank installed and Mark and Stephanie helped tweak the settings on my system. Since coming out on Friday my system is keeping the house very comfortable while being 10x quieter than what the installers left me with, despite it being -20 at my house yesterday morning. We run very little on Aux heat now even at those cold temps and on days like today where we are 20*+, the system runs a little while on stage 1 and turns off, something we didn't have much luck with prior to them coming out. Also, I had the matching thermostat for those Climatemaster digital systems installed and Mark and Stephanie made me very comfortable with changes to it that have greatly helped in creating a comfortable home!
