A heat pump can be a highly efficient companion to your existing Heating and Cooling system. It can help you save energy and provide you with both heating and cooling all while using less
energy. A heat pump is like an air conditioner in that it uses refrigerant and coils, but instead of generating heat, it quite simply moves it from one place to another.
Evaporation and Condensation
Like an Air Conditioner, a heat pump uses evaporation and condensation for heating and
cooling. A heat pump system contains two coils, and either one can function as an evaporator coil or condenser coil depending on the direction and flow of heat. The refrigerant in the system is evaporated in one coil, absorbing the heat surrounding it.
The refrigerant is then transferred to the other coil, which condenses it back into a liquid and releases the stheat that it has stored. The air handler inside your home blows air over the indoor coil, either distributing hot or cold air as is
necessary. This wopuld depend on whether you need your home heated or cooled, the
evaporation will occur inside or outside of your house.
An air-source heat pump absorbs heat from the surrounding air during the
evaporation stage. When the evaporator coil functions outside, heat is absorbed
and then released during the condensation phase inside your home. This then transfers heat from the outside to the inside. The opposite occurs during cooling phase.
This is why air-source heat pumps are so versatile—not only can they be used
year-round, but they can also coexist and even complement your existing HVAC system by using less energy during mild days. This means you only need to use your air conditioning
or heating system during the hottest and coldest times of the year.

Department of Energy Withdraws Energy Conservation Standards
For the last year or so it has been widely anticipated in the Heating and Air Conditioning world that changes were in the works regarding the efficiency requirements of residential furnaces. HVAC contractors like us have been expecting that furnaces with an efficiency rating of 80% would be banned in our region, and only furnaces with a minimum of 90% efficiency would be able to be placed in to service as of May 1, 2013. This is problematic due to the fact that many homes are not easily able to accommodate 90% furnaces due to the specific drain and flue requirements that the 80% furnaces do not have. On January 12, 2013 in a late afternoon settlement the Department of Energy agreed to withdraw the pending minimum energy conservation standards, and allow non-condensing 80% furnaces to remain legal to install until further notice. Good news for many homeowners that were concerned about the requirements and added cost to install more efficient models. While it is expected that these stricter energy regulations will re surface in the near future, at least homeowners will now have some time to prepare for these changes.
