Had Scottco install an HVAC, worst experience I've ever had with a service company. Where do I start? Lack of communication and open hostility between the sales and installation teams. Service guys screaming the F word in my attic all afternoon, cursing the incompetence of the sales people. Unfixed damage caused during installation, huge mess they left after two service visits to get the installation correct.

NEVER AGAIN.
