Freddie is a top-notch, quality service professional. He is knowledgable, respectful, considerate, efficient and very articulate when explaining how he serviced our system and his recommendations to improve it. He is not 'high-pressure' in trying to sell us something, which is very offensive. He knows that 'building trust and value' is very important. Thank you, Freddie, for taking good care of our HVAC system and us!
