As an HVAC contractor providing reliable service to commercial and residential customers in Southern California, one of the primary jobs of GLM Heating and Air Conditioning is to recommend and install high efficiency systems. Over the last decade, manufacturers have made unparalleled advances in operating efficiency for both heating and cooling units.
When buying a new HVAC system, consumers see acronym such as SEER, AFUE and HSPF. Even these systems have been around for about 20 years, many people have only begun to pay attention to efficiency as the green energy movement became more prominent. Those acronyms are measurement of efficiency standards for all heating and cooling equipment in the United States. If you’re in the market for a new system, GLM will help you become familiar with these numerical ratings and what they mean for your indoor comfort and your bottom line.
Central air conditioning systems have a SEER,(Season Energy Efficiency Ratio) that measures efficiency. The higher the number, the greater the efficiency. SEER is defined as the total cooling output during normal annual usage divided by total energy input during the same period. Cooling units in today’s market must have a SEER rating of at least 13, but units with SEER of up to 18 are on the market. We’ll help you determine which is right for you.
The warm side of your HVAC system has two standards, AFUE (Average Fuel Utilization Efficiency) and HSPF (Heating Seasonal Performance Factor). The first applies to furnaces and the second to heat pumps. AFUE indicates how much fuel is used to heat your home and how much goes into the atmosphere. Again the higher the AFUE, the better the efficiency. The most efficient furnaces have AFUE ratings of up to 97%, with 3% of fuel going up into the chimney as waste. As with other ratings, a higher HSPF rating indicates better efficiency. HSPF is calculated by taking total annual heating requirements, divided by the total electric power used. The most efficient heat pumps have an HSPF of 10. Contact GLM for any questions about high efficiency systems.
