Celebrate Earth Day by taking a chance on winning an easy-to-use Nest thermostat.
All day Monday, Service Experts Heating & Air Conditioning will be giving away one Nest Learning Thermostat every hour for 24 hours. To enter, visit the company's Facebook page each hour and answer a question. You don't even have to answer correctly to qualify.
The contest starts at midnight Central time, which is 1 a.m. Eastern time.
The Nest thermostat is designed to automate and simplify the process of programming a thermostat. It learns your schedule from the adjustments you make and also senses your presence, so it can adjust the temperature accordingly.
