SEER stands for Seasonal Energy Efficiency Ratio. It measures the efficiency of an air conditioning system over a cooling season. The higher the SEER rating, the more efficient the system is at cooling your home for each unit of energy consumed. For example, an AC unit with a SEER rating of 16 will be more energy-efficient than one with a rating of 10, resulting in lower energy bills and reduced environmental impact.
There are several reasons why your AC might blow warm air instead of cool air:
The thermostat is a device that controls the temperature of your HVAC system by regulating the heating or cooling. It senses the air temperature in the room and signals the furnace, heat pump, or air conditioner to turn on or off to maintain the desired temperature. Smart thermostats can also learn your preferences and adjust the temperature automatically to improve comfort and energy efficiency.
