I had 2 different visits from Fuller one was to re[lace a thermostat that wasn't working and the other was to see about adding an air duct to our new sun room
The first went well so no complaints there. The second was disappointed the only solution they could come up with would cost $4,000. and add and ugly base right by my side of the house. I researched and found alternatives that would work and let them know haven't heard a word back
