Before buying a heat pump system, it's important to know the potential downsides. Here are the cons of heating and cooling your home with a heat pump: Higher installation cost: Because heat pumps are more complex, they cost more to purchase and install than a comparable air conditioner.

Both focus on heating, ventilation and air conditioning. However, HVACR includes refrigeration. The “R” in HVACR refers to refrigeration systems that can be found in retail settings, warehouses or even the back of refrigerated trucks.

A central air conditioning system uses vents, ducts, and a plenum (a box responsible for moving air) in a forced-air setup to deliver temperature-regulated air. A central air conditioning system uses the same duct system your furnace does to distribute cool air throughout your home without no other connection.

Water heaters are actually part of your plumbing system, not your HVAC system, because their purpose begins and ends with the temperature of the water supplying your faucets, showers, dishwasher, and washing machine.
