We have used Climate Master for over 10 years to maintain our furnace and air conditioning unit. Kimie calls us to schedule our inspections/cleanings, and always calls before the appointment as a reminder. Shawn is friendly, knowlegeable, thorough and always explains what he is doing clearly and simply. He covers his shoes before walking through the house. I would recommend Climate Master to anyone who is looking for an honest, reliable company to service their heating/air conditioning.
