Hello, I'm looking for some help to correct a poor hvac installation in my home. I live in the NYC area and I hope to find one that can fix a few major problems with my system.

First, I need to install some sort of return in a very cramp hvac room. Also, I need to ensure I have an efficient humidifier system on it and last, I need someone to make sure that everything else looks good as the installation was pretty shotty.

Any recommendations would be appreciated. Thanks!
