Also know, what does Stage 2 mean on a thermostat?

Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household heating demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.

why does my thermostat say Stage 1 and 2? 2nd stage is the full compressor capacity of your system. 1st stage is roughly 2/3 compressor capacity. Generally, 1st stage is a bit more efficient than 2nd stage, but systems are designed to use both stages, so no worries there. When it is cold outside, it is fine for your system to have long run times.

Also asked, how does a dual thermostat work?

When multiple thermostats control one system, the house is divided into zones using dampers in the ductwork throughout the house. When one zone needs heating or cooling, the damper for the ductwork in that zone opens, guiding the warm or cool air to that zone.

How do I know if I have a dual fuel system?

The easiest way to determine if you have a dual fuel system is to ask your local heating system repair company. However, it may be possible to determine this without a service call. The first place to look for this information is on the metal box inside or outside your home that controls your HVAC system.
