Heat Pumps

Trane Heat PumpOne may wonder how a Heat Pump actually differs from an Air Conditioner. Heat Pump systems are air conditioners in the summer; however, they are also heating units in the winter. The heat pump is equipped with a reversing valve in the compressor which differentiates it from an air conditioner. An air conditioner compresses a hot liquid into a cool gas for dehumidification purposes for cooling, and the Heat Pump does also; however, in the heating cycle a heat pump utilizes the reversing valve to do the opposite. The heat pump actually takes a cool gas and turns it into a hot liquid circulating the hot liquid across the evaporator coil to produce heat. This application will work until the temperature outside reaches approximately 37 degrees at this point the heat pump has an outdoor thermostat which sends a signal to the indoor thermostat for supplemental heat. The indoor air handler is equipped with auxiliary strip heat which will supplement the heat pump to provide the extra heat needed in order to keep the home nice and warm. The difference between gas heat and the heat from a heat pump is merely the temperature at which the heat is delivered. Gas heat is much hotter and therefore feels warmer to the touch.

Rheem Heat PumpHeat Pump systems perform best in southern type climates. A heat pump system can be a cost effective choice when compared to standard electric baseboard heat which can be quite costly. Heat pumps ranging from 13 to 19 SEER along with package Heat Pumps and Dual Fuel are available. 13 seer is the minimum efficiency available. High efficiency, 16 seer units, use a significantly lesser amount of electric and are a good choice especially where other types of energy such as natural gas are not available. High efficiency heat pumps can be significantly less expensive to operate as compared to electric baseboard.

Package units, or combination units, are gas heat and air in one unit. These units are used primarily for homes with low crawl spaces, or homes with damp crawl or where a standard heating-ac configuration is not possible or practical. They are dependable and very easily serviced.

S.E.E.R. is an acronym that stands for Seasonal Energy Efficiency Ratio. The more energy-efficient an air conditioner is, the higher its SEER rating will be. The SEER rating of an air conditioner measures efficiency over a whole season, and the energy efficiency ratio (EER) rating measures it for one given point in time. It is possible to see significant savings in cooling costs by upgrading to a more efficient air conditioner, in many cases. For example, an upgrade from a 9 SEER to a 13 SEER would translate into 30% less energy used per season. This can potentially result in hundreds of dollars of savings per year, to the point that a new unit could even pay for itself in savings. An efficiency rating, much like how miles per gallon (MPG) is used to rate automobile efficiency. We all understand that if you drive 300 miles and consume exactly 20 gallons of gas, then your vehicle’s fuel efficiency (MPG) is 15 miles per gallon (300 miles divided by 20 gallons). A vehicle that gets 18 MPG would be more efficient (less costly) to operate, and a 12 MPG vehicle is less efficient (more costly) to operate. For HVAC, S.E.E.R. follows the same rationale.
