Consider making a change if any of the following statements apply:
Some of your rooms are too hot or cold
Inadequate air sealing or insufficient insulation could be the cause. No matter how efficient your heating and cooling system is, if your home is not properly sealed and insulated, you will not be as comfortable and your system will have to work harder.
Your home has humidity problems, excessive dust, or rooms that never seem to get comfortable
Leaky or poorly insulated ductwork might be the cause.
Your equipment needs frequent repairs and your energy bills are going up
In addition to the rise in energy costs, the age and condition of your heating and cooling equipment may have caused it to become less efficient.
Your heating and cooling equipment is more than 10 years old
Consider replacing it with newer, more efficient equipment. And remember, high-efficiency levels begin with ENERGY STAR.
You leave your thermostat set at one constant temperature
You could be missing a great energy-saving opportunity. You can set a programmable thermostat to adjust your home’s temperature at times when you’re regularly away or sleeping.
