Furnaces generate heat by burning fuel or using electric resistance heating. Heat pumps transfer heat from outdoor air into your home during winter and reverse for cooling during summer. Heat pumps provide both heating and cooling in a single system and typically operate more efficiently than electric furnaces, though they may require backup heating during extremely cold weather.

Modern thermostats offer automatic temperature adjustments based on your schedule, reducing energy waste when you're away or sleeping. Many smart thermostats learn your preferences, provide energy reports, allow remote control, and send maintenance reminders. Washington, MO homeowners typically reduce energy costs by 10-15% through proper thermostat programming.
