High static pressure in your HVAC is an industry term referring to the measurement of air resistance encountered by the blower. The more resistance the blower encounters the higher its static pressure.
Reasons for this could be poor system design, ductwork not being installed properly, or poor filter choices.
Your HVAC system must circulate air throughout your home by pulling hot stale air over an evaporator coil and sending it out through the ductwork. If the system cannot perform this operation properly it may fail to achieve the desired temperature.
High static pressure will inhibit circulation. Your HVAC system will be exposed to greater resistance, which can lead to other problems.
Higher Cooling Costs
You’ll have to spend more to cool your home during the summer if your HVAC system has high static pressure. This is because the length of cooling cycles is influenced. With low static pressure, the cool air will quickly circulate throughout your home, resulting in short cooling cycles. With high static pressure, it will take longer for the cool air to circulate throughout your home, resulting in long cooling cycles.
Uneven Cooling
With high static pressure, the blower will encounter greater resistance which can cause uneven cooling. You may notice that some rooms feel cooler than others. The blower may push cool air into some rooms, only to leave other rooms untouched.
Increased Air Pollution
Levels of airborne pollutants inside your home may increase with high static pressure. Your HVAC system doesn’t just cool and warm your home; it cleans the air. The blower will circulate hot, stale air through a filter removing dust, pollen, and other pollutants.
High static pressure can minimize the amount of air that reaches the filter. With less air going through the filter, levels of airborne pollutants will rise.
High static pressure isn’t something you should ignore. It can cause higher cooling costs, uneven cooling, and increased air pollution.
If you believe this phenomenon is affecting your HVAC system, contact a professional today. Problematic, high static pressure can most likely be fixed by making adjustments to your HVAC system’s ductwork and equipment.
