According to the U.S. Department of Energy, more than half of all heat-pump systems are inefficient due to incorrect refrigerant charge, inadequate airflow, and ductwork leakage. This is a startling statistic considering that heat pumps are among the most efficient heating and cooling systems available. Heat-pump systems can provide up to four times the energy that they consume, saving you somewhere between 40 to 80 percent in heating and cooling costs.
However, to capitalize on these energy savings, just like any other mechanical equipment, your heat pump and ventilation system need regular maintenance to ensure correct refrigerant levels, optimal ventilation and airflow, and efficient year-round performance.
Boost Performance For Energy Savings
Your home’s ductwork must be sealed for accurate airflow and refrigerant measurements. Without efficient ductwork design and ventilation, your heat pump will never achieve optimal efficiency. As much as 30 percent of heating costs are lost due to ductwork leakage, inadequate insulation, and obstructions in the ductwork. A heating and cooling professional should thoroughly examine your ductwork for these deficiencies.
Sealing your ductwork will improve energy efficiency, and it is necessary to receive accurate airflow and refrigerant measurements. If airflow is too high, the indoor and/or outdoor fans can be adjusted. If the airflow is too low, cleaning the evaporator coil and/or increasing fan speeds should solve this. The technician should test airflow at each air-supply register, and check the air filter for proper fit and efficiency rating.
Once the technician has determined that your airflow is at peak efficiency, he will test the refrigerant for leaks and correct levels. This should be done every service call. Refrigerant levels should be charged within a few ounces of the manufacturer’s specification. Once the technician has correctly charged the refrigerant, the measurements for temperature and pressure should match manufacturer specs.
A detailed annual service plan is important for the longevity of your heating and cooling equipment. If you would like to schedule a service call, or have any questions about heat-pump systems, call Smoky Mountain Heating & Air.
