Explained everything clearly and was great with my crazy dogs!
Quoted two new Fujitsu Ductless Mini-Split Heat Pump Systems.
System was operational at time of arrival. Recommend replacing system with a larger more efficient system to take care of the airflow issues and efficiency. Gave homeowner an estimate for system replacement. He will talk to his home warranty company to see if they will work with him to replace system. Also will talk to his brother, who is part owner as well.
