The installation of my new furnace & humidifier (106224 ) was well done. The techs cleaned up after themselves and laid down carpet so they didnt drag dirt into the house, as they went back and forth from their van. The units they installed have been working flawlessly for 2 weeks now and the house is much better heated than my prior unit. I was happy dealing with the sales rep, Cormac, as well. He was knowledgeable and responsive. Homestar Heating work directly with Costco so they r also endorsed by them. Time will tell, but for now, they delivered on what they said they would do.
