Is it time to replace your equipment?
It may be time for a change if:
Your equipment is more than 10 years old or it needs frequent repairs and your energy bills are going up.
The age and condition of your heating or cooling equipment may have caused it to become less efficient. Oversized units tend to have shorter lives due to "short-cycle," or turning on and off rapidly, which inflicts excessive wear and tear on the compressor. Consider replacing it with newer, more efficient ENERGY STAR certified equipment.
Some of your rooms are too hot or cold (this could also be due to inadequate air sealing, windows or insulation.
Your home has humidity problems, excessive dust or rooms that never seem to get comfortable (this could also be due to poorly insulated ductwork).
You tend to leave your thermostat set at one constant temperature.
You could be missing a great opportunity to let an ENERGY STAR certified smart thermostat adjust the temperature to save energy while you are asleep or away.
