If your heating and cooling bills have gone up, there are hot and cold air pockets in areas of your Prince George, VA home, or some rooms are not as comfortable as others, there may be a drop in efficiency of your heating, ventilation and air conditioning system. There are many reasons for this, including leaking ducts, improperly maintained equipment, an overtaxed HVAC system, and poorly installed systems. A certified HVAC contractor has the training and tools to test and evaluate an HVAC system’s efficiency.

Examine Ductwork

If your utility bills seem higher, leaking ducts may be to blame. The Department of Energy estimates that up to 40 percent of conditioned air is lost through leaks, holes and poor connections in ducts. Repairing, sealing and insulating ducts is one of the best ways to improve energy efficiency and reduce heating and cooling costs by hundreds of dollars each year.

Balance the HVAC System

Balancing looks at airflow, pressure, duct leakage and the pressure of fans, filters, and coils. Your HVAC contractor can compare the operating performance of the system with the manufacturer’s specifications. HVAC manufacturers test equipment under optimum conditions to determine a system’s energy efficiency and performance capacity.

Check the SEER Rating

Each air conditioner has a listed Seasonal Energy Efficiency Ratio (SEER) that measures energy efficiency. The cooling output during the months the air conditioner operates is divided by the amount of electricity required to run it. Higher SEER ratings mean better efficiency.
To reduce energy usage, the Department of Energy began requiring minimum SEER ratings in 1992. The first was 10. In 2006 it was 13. In 2015, ratings were defined for each area of the country. In the Southeast, which includes Virginia, the minimum is SEER 14.
