"AC died in the July heat wave, they were here the same afternoon, capacitor swapped, readings shown to me on the gauge, and the flat phone quote held exactly."

"New heat pump plus two ductless heads for the ADU. They ran the load calc room by room, filed the rebate paperwork with us, and the effective price beat every other bid."

"The back bedroom was always five degrees off. Two other companies quoted new equipment, Northwind sealed and balanced the ducts for a fraction and fixed it completely."

"They talked me OUT of the bigger unit. Explained short-cycling with actual numbers, installed the right size, and the house has never been this comfortable in August."

"Furnace out at 6am in January, no-heat line answered on the second ring, warm by early afternoon. The igniter cause was explained, not just billed."

"The comfort studio on their site is adorable, we tapped through the temperatures and the whole page changed mood. Booked the assessment that evening."
