Professional HVAC companies know that static pressure is an important factor in keeping air circulation in the home balanced and comfortable. As to resistance to airflow in your system’s ductwork and equipment, it’s necessary for the pressure to be greater than the resistance to the flow of air for it to properly circulate through the ducts.
It’s really not difficult to understand how static pressure works when you think of blood pressure and how it’s checked regularly by a doctor to get a good handle on your overall health. This is essentially the same when your HVAC system’s static pressure is checked by a technician, since it will give an idea of the overall condition of your system.
High static pressure on your system is contributed to by poor system design and shoddy duct installation. These factors, as well as having low-grade air filters, can all be likely causes. In any case, with high static pressure your system won’t reach its full potential and will end up operating inefficiently, which is why professional HVAC installation contractors recommend having such problems addressed as soon as possible.
High static pressure on an HVAC system means less energy-efficiency than it would have with balanced pressure. Here are some of the common problems you need to look out for:
1. Excessive noise. Your HVAC system should run with low to minimal noise If you think it sounds louder than it should be, this could mean that it has static pressure problems. Keep in mind that the air going through the return grille, ducts and vents is moving fast at high pressure, so you’ll still likely hear some noise.
With high static pressure, the airflow is decreased, so it forces your unit’s blower motor to work harder to move air through the system. When this happens, the motor will ramp up to maximum speed to try to keep the air flowing like it’s supposed to, which makes the noise significantly louder.
2. Hot and cold spots. IF one part of your home feels cooler or warmer than the rest, this could be an indication of high static pressure. This means the air isn’t moving through a balanced system, which definitely isn’t efficient for your HVAC unit. If this is the case, have it serviced immediately.
