The best time to schedule an air duct leakage test is during the mild spring or fall seasons. During these times, your HVAC system is not under extreme demand for heating or cooling, making it easier to identify and address any issues with the ductwork. Additionally, scheduling the test during these seasons allows you to optimize your HVAC system's efficiency before the more challenging summer or winter months, ensuring comfort and energy savings throughout the year.

The best location for return air vents is strategic to ensure balanced airflow and temperature control. In most homes, placing them in central, open areas like hallways or large living spaces is most effective. Ideally, they should be located across from a supply vent. Climate is also a factor: in warm climates, place vents high on the walls to help remove rising hot air, while in colder climates, lower placement is better. It's also important to ensure that vents placed low on walls are not blocked by furniture. The optimal placement ultimately depends on your HVAC system's design, your home's specific heating and cooling needs, and the accessibility of the ductwork.

Failing to open your flue can lead to serious health hazards if you start a fire because the smoke will back up into your home. Breathing fire smoke, even in relatively small quantities, is bad for human lungs, and smoke can also irritate your nasal passages and eyes. Furthermore, smoke can cause damage to your interior fixtures and furnishings, at the very least leaving an unpleasant smoky smell for a long time. In short: If your flue isn’t open (or you’re not sure if it is or not), don’t start a fire to find out!

No, FPR isn’t necessarily better than MERV. Both systems measure an air filter’s effectiveness, but they express it on different scales. FPR ratings range from 1 to 12, while MERV ratings run between 1 and 20. However, some people might find FPR ratings easier to understand since they’re color-coded and have descriptors like “good,” “better,” and “premium.”
