Airsmiths Home Performance did a complete replacement of all ducts and insulation for our residence and they did a good job. Their technicians were professional and efficient in the work they did. They did a complete and thorough job; they did things like give us additional outlets, which I appreciated. Their technicians arrived on time and were communicative, explaining what was going on at each step so we were in the loop. Everything has been working well, and overall, I would say I am pleased with them.
