As a licensed partner with American Standard and Nexia, crucial diagnostic data can be retrieved through a service porthole right in the office at Ervin-Moser Residential Service. With your approval, your thermostat can send a 30 day log of information on indoor/outdoor temperatures, system run time data, and other stats that help determine the cause of a problem you are having at home, before your technician even arrives! This can save time on your trip out to service your system and get you warmer or cooler even faster!
