Energy-efficient HVAC equipment is a great addition to any home. Such equipment typically costs more to purchase, but frequently more than makes up for this with savings on energy bills over the years. Additionally, it tends to have more advanced features that can offer increased comfort and convenience.
Furnaces are probably the most common piece of HVAC equipment, and their efficiency is expressed by their annual fuel utilization efficiency (AFUE), which tells you what percentage of the energy they consume makes it into your home as heat. The most efficient models are condensing furnaces. These furnaces end up extracting so much heat from their combustion that condensation forms in the exhaust fumes. High-efficiency furnaces also use advanced fans in their air handlers that can operate at a range of speeds to improve their efficiency. Efficiency works much the same way for boilers, except they don’t use fans for heat distribution.
Air conditioner efficiency works a bit differently. It’s measured by the seasonal energy efficiency ratio (SEER) and the energy efficiency ratio (EER). The SEER is a more modern efficiency rating that is meant to represent the air conditioner’s performance over the course of the entire cooling season, but the EER is still used because it gives a better indication of how the air conditioner performs in hotter weather.
Air-source heat pumps work much the same as air conditioners in the summer and have the same efficiency ratings, but in the winter they are also able to provide super efficient heating. They provide heat differently from furnaces, so their efficiency is expressed by a different measure: the heating seasonal performance factor (HSPF). It describes how much heat they move into the home as compared to how much energy they use to do it. There are also geothermal heat pumps that can provide even better heating and cooling efficiencies because they utilize the moderate temperatures that are found underground year-round.
