Arrived on site to perform maintenance on system. Upon arrival and speaking to homeowner, he would also like a diagnostic/inspection of new system that was just installed by another company to ensure that it was installed correctly, and/or point out anything that wasn’t done correctly. Advised that if he wanted a more thorough inspection of newer system, the $69.95 would also apply to that system as well. Homeowner decided to only work on the new system, as the other company recently checked out the older system anyways. Inspected new system to see if there were any concerns with the installation.
