We've been using Tempasure for several years now. It started with simple maintenance. Then, once our old furnace started to show signs it was on its way out, Tempasure provided a replacement solution that worked for us. Since then, we've gotten them to provide annual inspections (including replacing humidifier filter) and recently, when we noticed a small amount of water pooling at the base of our furnace, they sent a technician over right away (in the middle of a typical busy, hot summer!) to quickly address. Tempasure prides itself on customer service & they don't disappoint.
