From humidity problems and excessive dust to poor operating or improperly sized equipment.
Leaky ductwork can also cause these problems, so having it sealed may be a solution.
According to ENERGY STAR, consider making a change if:
- Your home has humidity problems and/or excessive dust. Poorly operating or improperly sized equipment could be to blame. Leaky ductwork can also cause these problems, so having it sealed may be a solution. Monthly maintenance of your heating and cooling equipment’s filters may also help.
- Your cooling system is noisy. Your duct system could be improperly sized or there may be a problem with the indoor coil of your cooling equipment.
- Your furnace is more than 12 years old or your boiler is more than 15 years old. Consider replacing with ENERGY STAR qualified equipment. ENERGY STAR has set high efficiency guidelines for both.
- Your score on the ENERGY STAR Home Energy Yardstick is below six or seven. That means you’re using more energy at home than most Americans and probably paying more than you need to on energy bills.

But don't just guess. The best way to know if a new system is the best answer for your comfort and energy-savings needs--and for your peace of mind--is with a proper home energy assessment. The right assessment will help you determine the real issues and arrive at the solutions that make the most sense for you and your home. And you may be surprised. While sometimes a new system is just the ticket, it often makes sense to address insulation and air-sealing first, before installing a new furnace or air-conditioner.
