Either a heat pump or an a/c will easily do the job when looking for an HVAC method to cool your home. Both systems use the same sort of compressed refrigerants to collect heat from inside your home as air passes straight over the coil in the air handler plus transfers it outside. Heat pumps plus a/cs are excellent because they both move heat from inside your home to an outdoor location. Heat pumps plus a/cs are often so similar that by looking at them in person, it would be difficult to tell them apart; From a mechanical cooling perspective, heat pumps plus a/cs are the same when operating in cooling mode, with basically no significant difference in operation, efficiency, or energy bills. While they are perfectly identical in cooling mode, the heating mode is a completely unusual story. Air conditioners honestly do not provide heating, however heat pumps do. A heat pump can quickly absorb heat energy from outside air plus move the heat into the inside of the home where it rapidly releases the heat into the air. A heat pump can heat plus cool, however an a/c system cannot, which is the primary difference between the HVAC systems. An a/c is constantly paired with an oil furnace to provide heat during the chilly weeks. Together, an official a/c plus oil furnace are a complete heating plus cooling system. Although a heat pump can easily heat a home, when outside temperatures drop below freezing, the efficiency of a heat pump is drastically affected as the device requires more energy to maintain moderate temperatures during those times inside the home. Both a heat pump plus an a/c are an enjoyable choice for modern homes, however 1 might be more appropriate for you, depending on yours.
