HVAC Static Pressure

What Is Static Pressure?

If static pressure is present in your HVAC system, then there’s air resistance. HVAC systems need to have efficient airflow to operate accurately. When there’s too much resistance, your ductwork can’t distribute air throughout your space. This malfunction can lead to hot and cold spots and spiked utility bills. 

As the leading HVAC company in Colorado Springs, Polar Bear Mechanical understands the need for an efficient heating and cooling system. Our HVAC technicians have special equipment to measure your system’s static pressure and make sure it’s optimal.

High Static Pressure vs. Low Static Pressure

You want the pressure within your duct system to be balanced. So, you don’t want static pressure that’s too high or too low. Uneven air pressure may be due to improperly sized equipment, such as a furnace that’s too small or too big. When a component of your HVAC system isn’t the correct size for your space, it affects the entire system and can lead to uncomfortable and costly issues.

Did you know almost half of all HVAC systems are sized improperly? So, those HVAC systems have improper static pressure and can’t perform to their maximum abilities.

What Causes High Static Pressure?

Air duct systems are designed to move air from one point to another. Whether you have a large commercial space or a smaller home, you need optimal ductwork for your space to be heated or cooled correctly. When an air duct system is incorrectly designed or installed improperly, the static pressure shifts and spikes. Some reasons your system may be suffering from high static pressure include:

Undersized Return Air

Your HVAC system has a component called a compressor. The compressor is responsible for pumping high-pressure refrigerant throughout your system. Unfortunately, if you have too little return air, your system may be forced to unnecessarily send refrigerant back to the system. If this happens long enough, it can decrease your compressor’s lifespan.

Poor Ductwork Installation

If your ductwork is installed poorly, it can also cause high static pressure. When air ducts are sagging, bending, dipping, or have any other inconsistencies, it’s necessary to have them reinstalled or replaced to restore your system to optimal condition. In some situations, you can install a variable speed blower motor to improve the airflow.

Improper Air Filters

Even though most people use 1” pleated air filters, they can cause resistance within your duct system. The thicker the air filter, the more that air struggles to pass. To help prevent high static pressure, you can use filters with low pressure drop. It’s important to install air filters that will properly filter your air without causing excess resistance.

High Static Pressure SOlutions

If you’re suspicious of high static pressure in your HVAC system, it’s crucial to have one of our HVAC technicians take a look immediately. If your HVAC equipment is trying to combat improper air pressure, you’re probably dealing with hot and cold spots and increased utility bills. It’s important to make sure the total pressure in your air ducts is balanced and that airflow is optimal. Some ways to fix high static pressure include:

Replace Your Air Filter

One of the simplest ways to fix high static pressure is to replace your air filter. When an air filter gets clogged, it’s nearly impossible for air to flow through properly. If you have a 1” filter that says to be changed every 90 days, decrease the amount of time between replacements to 30.

Renovate Your Ducts

Each duct system is unique and built specifically for the space it’s in. So, if your air ducts don’t have enough room to carry the amount of air necessary for your space, we can renovate the system to meet your needs. Renovation may include sealing your ducts and restructuring the system.

Our Static Pressure Testing Services Are Just The Tip Of The Iceberg

If you’re dealing with hot and cold spots in your home or business, a noisy HVAC system, or high utility bills, the culprit of your faulty HVAC system may be high static pressure. If you think you’re experiencing static pressure problems, it’s crucial to schedule an appointment with our HVAC professionals as soon as possible. We’ll use special equipment and our years of experience to ensure your heating and cooling system has everything it needs to function properly.
