These guys did a great job. Laid down cloth and took of their shoes, very professional, curious and did a great walkthrough of the job.
They physically showed me the return air ducts, and also provided before and after photos, I would recommend for sure based on the work they did
However, and this is partly my fault, you need to understand your quote. Over the phone I asked for an all inclusive quote as I did a renovation, when they got here it was a slightly different story that cost me an additional $150+ tax
I didn't' know as a customer that the ducks going to the AC unit aren't considered as part of the original quote so it was an additional $89, then, the inside of the furnace as well, not covered in the original quote - $69
I had let them know I did a renovation, and the idea of having to clean my furnace never came up which is odd.
Anyhow, the job was great, I likely had to do a better job on knowing what I was getting.
