HVAC service is a highly specialized field, and as such, there are a handful of phrases, abbreviations and terms that are understood only air conditioning and heating contractor or HVAC educated. While this can be a little intimidating, which system most efficiently connected at first glance, simply getting a hold of some of the key terms and labels with HVAC can provide you with competent and ready for the decisions about your HVAC service and above all.
The following is our brief, tip-of-the-iceberg Glossary of Acronyms popular HVAC service to distinguish between the qualities of the units.
BTU - British thermal unit is a traditional unit of energy output. BTU is used for the measurement of heat, but in terms of HVAC, BTU used as an indicator of how much energy is an HVAC unit production. This can be cleaned in the form of cooling, heating, or air.
SEER - Seasonal Energy Efficiency Ratio has become a standard for evaluation of efficiency HVAC systems. Mathematically, SEER, BTU calculated by a typical cooling season by the total electric energy input during the same period. The higher the SEER, the more efficient the machine. In the United States, all new residential systems are required to have a SEER rating of at least 13, with a rating of 14 is to qualify for ENERGY STAR label. Current residential air conditioners achieve a SEER of 27.2, with even stronger units on the horizon when certain technological limits are exceeded.
HSPF - Heating Seasonal Performance Factor is strongly correlated with SEER, but focuses on the efficiency of a unit rather than its cooling capacity. Mathematically, the HSPF BTU of heat in a season divided by the watt-hours of energy. If the resulting number is greater than or equal to 8 HSPF, as the system is very powerful and could be the.

AFUE - Annual Fuel Utilization Efficiency is a thermal efficiency measure of combustion systems such as furnaces and boilers. Furnace repair and replacement is expensive, so is a high AFUE rated unit will make the best out of change, if necessary. The number itself is a dimensionless ratio to bring the efficiency of the output compared to the input of the system expressed, for example, if the system input 100 BTU with a 90 BTU heating capacity than would AFUE 90%, respectively. For boiler repair AFUE is to distinguish a simple, go-to-vote between systems for a final decision....
