"Called for a tune up on a 9 year old condenser. The tech showed me the fin pack had about 55% pitting from the marina salt air and the capacitor was already drifted to 32 uF on a 40 uF rating. He did not push a sale, he gave me a written recommendation to plan replacement in the next 12 months and a coil rinse to get me through the season. Honest call, fair price for the visit, and the rinse bought me time to budget."
"High rise with limited duct chase access. They did a partial trunk redesign and AeroSeal interior sealing on the runs they could not reach. Duct leakage to outside dropped from 19% to 5%. TESP measured 0.62 in. wc. They knew exactly which permit path Building & Safety wanted."
"Nest Learning v3 install on a Carrier Infinity 24VNA0 system. The tech installed it correctly and it works fine. Reason for four stars is the Infinity controller offers more granular control than the Nest can pass through, which I learned after the fact. Not the installer's fault but I wish someone had flagged the tradeoff during the consultation. The crew itself was on time and professional."
