AVERAGE RESIDENTIAL HVAC SYSTEM IN THE U.S ONLY DELIVERS 57% OF THE EQUIPMENT HEATING AND COOLING TO THE HOME
FIND OUT THE TRUE CAPACITY OF YOUR HVAC SYSTEM BY MEASURING IT.
IF YOU'RE NOT MEASURING YOU'RE JUST GUESSING.
Airflow is the main factor determining equipment efficiency. If airflow is incorrect, everything else will be incorrect, including refrigerant charge which will lead to misdiagnosis which will turn to repeat call back and a lot of expenses.
Homeowners, builders, building codes and equipment manufacturers are focus on SEER rating. Many things affect the SEER rating of the equipment; airflow being the biggest one of them.
Furnace blower are designed to operate at a maximum static pressure. Think of static pressure as resistance. Blower can overcome a certain amount of resistance, past this resistance, the blower cannot maintain airflow. Air filters, evaporator coil, supply ducts, return ducts, dehumidifiers, etc.. all add resistance to the furnace blower.
Newer furnace blower can overcome high static pressure but as static pressure increase so does the electricity the blower uses, reducing the SEER rating of the equipment.
Filters can have a negative effect on system airflow. Homeowners should be very careful when choosing a filter. Some filters may have too much resistance for your system airflow.
Below is an example of how much resistance a filter can add to the system.
The lack of airflow also influence equipment longevity, equipment efficiency, comfort and humidity level inside the house.
Homeowners should test their existing HVAC system airflow before replacing to a new high efficient HVAC system.
Our comprehensive report clearly shows what part of the system negatively affect airflow. So before you spend money on a high efficiency unit, call us to perform a system airflow test and will know exactly what need to be done to improve airflow so the new system will perform as designed.
