Summers don’t come any hotter than they do in Hammond, LA, where the Deep South brings both high temperatures and stifling humidity. Good air conditioning systems are an absolute necessity in such an environment, but you also need to ensure that your energy costs don’t run away with you in the process. Many local residents prefer to use a heat pump instead of a traditional air conditioner, since it is a strong money-saving alternative to home HVAC systems. But how does a heat pump work? More importantly, what’s the difference between a heat pump and a standard air conditioner? We’ve included a quick primer below.
How Heat Pumps and Air Conditioners Work Similarly
Both heat pumps and air conditioners rely on the same engineering principles to function. Refrigerant first moves into a condenser coil, usually located outside your house. The refrigerant condenses into liquid form, releasing heat into the outside air. From there, it moves inside your home to an evaporator coil, with shifts the liquid into gaseous form, pulling heat from the air as it does so. The cool air can then be blown into your house with a fan, while the gas then returns to the compressor coil to start the process anew.
How a Heat Pump Reverses the Refrigeration Cycle for Heating
Unlike air conditioners, heat pumps can be “reversed” in the winter so that the outside coil serves as the evaporator (pulling heat from the outside air) and the inside coil serves as the condenser (releasing heat into your home). That means they can serve double duty as both a heater and an air conditioner, saving you money on installation and heating and cooling bills in the process.
Frequently Asked Questions
Question: Does a heat pump use more electricity than a central air conditioner?
Answer: In cooling mode, comparable heat pumps and central air conditioners can have similar electricity use because they operate on the same basic refrigeration cycle. Overall energy costs differ because a heat pump also provides heating, while a standard AC requires a separate heating system.
Question: Do heat pumps control indoor humidity as well as air conditioners?
Answer: Heat pumps remove heat and moisture from indoor air during cooling much like standard central air conditioners. Proper sizing is important because an oversized system may cool the home too quickly to provide effective humidity control.
Question: Can a heat pump use the same ductwork as my existing air conditioner?
Answer: A ducted heat pump can often use existing ductwork if the ducts are properly sized, sealed, and in good condition. An HVAC professional should inspect the system because airflow requirements or damaged ducts may require modifications.
Question: Which lasts longer, a heat pump or a standard air conditioner?
Answer: Both systems can provide many years of service, but actual lifespan depends on usage, installation quality, climate, and maintenance. Heat pumps may accumulate more annual operating hours because they can run during both heating and cooling seasons.
Question: Can I replace my existing air conditioner with a heat pump?
Answer: Many homes can replace a central AC with a heat pump, especially when the existing ductwork and electrical system are suitable. The installation should also account for heating needs and whether backup heat is necessary for the home.
