Your ductwork is the unsung hero of your HVAC system. Although it spends its time quietly out of sight and out of mind, this key component is responsible for delivering air from your air conditioner or furnace into every room of your house. If your ductwork is damaged or not functioning properly, then it can lead to a number of efficiency problems with your system.
Duct tests are the best way to determine if there are leaks in your system, but these are not generally performed as part of a routine HVAC maintenance schedule.
Home energy audits are a great way to identify areas where your home's energy usage is less efficient than it could be. By locating trouble spots in your home's energy profile, you can save money on your energy bills and reduce your carbon footprint. This makes an energy assessment a rare example of something you can do that is both good for the planet and good for your wallet. Since it is easy to find information on the most common areas where your home may be using too much energy, it can be tempting to try to perform this evaluation on your own.
