Called for a preventative service appt. They had flexible time blocks to work within my schedule. They called when the tech was on his way, as a courtesy. I left work, met the tech at my house (right on time!). I felt valued and respected without being 'sold' on unnecessary services. I was advised of upcoming probable maintenance but certainly not pressured. I will 100% have them back for the heater preventative maintenance in December. Thank you!
