If the HVAC system is highly efficient, it will keep the house cool in scorching heat and warm in cold weather.

But if you want all the above comfort, the HVAC system has to run efficiently, which means all the components or the parts of the unit must be in good condition. One such part is a thermostat, which plays an essential role or it is the direct way of communication to the system. Minor issues in the thermostat can mimic severe problems with the unit, which directly impact the cooling system performance and, no doubt, your comfort.
