Frequently Asked Questions (FAQ)

I am having a contractor replace my central air conditioning system with a newer more efficient model. I am having the work done by Sears who contracted out the installation to a local licensed contractor. The contractor just recently installed the AC unit and I am concerned that the installation is not to code (which by contract they were required to do.) For example, the AC unit is placed directly in front of an electral junction box therefore blocking access to it. Where can I find the building code requirements/standards for AC installations. I am interested in setback requirements from house and/or clearances from electral equipment and support/foundation requirements for the AC unit itself and for the copper refrigerant lines. Any help you can give me would be greatly appreciated.
