Heat Pump vs. Air Conditioner: How to Compare
Heat Pumps and Air Conditioner: Similar Technology, but Heat Pumps Save Money and Offer More
Chances are, you’re reading this in a building with at least one air conditioning unit and about 91% also have central heating systems.
These systems work together to maintain comfort, using ductwork to transfer warm air in the winter and cool air in the summer. However, traditional HVAC systems can be inefficient, especially those relying on fossil fuels for heating. Central air conditioners are good at moving cold air, but older systems can waste 30-44% of their generated energy.
Heat pumps provide a more efficient alternative by drawing heat energy from the air, offering both heating and cooling. If your home relies on window air conditioning units, switching to heat pumps is a significant upgrade. Window A/Cs can use up to three times as much energy as heat pumps to keep you comfortable during the summer.
So, what’s the difference between a heat pump and an air conditioner? If you need to replace your A/C units, should you consider upgrading?
At Shenling, we specialize in heating and cooling heat pump manufacturing, focusing on air-source heat pump technology that delivers numerous benefits over traditional HVAC systems. Our heat pumps provide reliable comfort year-round and can save you up to 40% on utility bills, depending on local energy prices.
Heat Pumps vs. Air Conditioners: Understanding The Basics
Air conditioners and heat pumps operate using the same basic cooling process, but heat pumps can reverse this process to provide heating. By upgrading to a heat pump system, you eliminate the need for a separate boiler or furnace.
Here’s how an A/C system works:
- The indoor unit acts as the evaporator, with ambient air passing over coils filled with refrigerant that absorbs heat and humidity.
- As the refrigerant heats up, it turns into gas, which is then compressed by a large electric pump, turning it back into liquid.
- The outdoor unit contains a condenser coil, where a fan pulls in outside air to release the heat energy.
In cooling mode, air-source heat pumps and central air conditioners operate similarly, with comparable appearance, noise level, and energy efficiency ratings. However, heat pumps have a unique component: the reversing valve, allowing them to function as both an evaporator and a condenser, providing heating when needed.
Heat pump systems come in two types: ducted and ductless. Ducted systems connect to existing ductwork, while ductless systems—often referred to as mini-split or multi-split—consist of outdoor units connected to indoor units via refrigerant lines. Ductless systems allow for precise room-by-room temperature control and are generally more efficient since they deliver air directly to the living space.
How Does a Heat Pump Heat?
Heat pumps efficiently heat and cool your home by transferring heat rather than generating it. During winter, air-source heat pumps extract warmth from the outside air, even in low temperatures. A refrigerant circulates between the indoor handler and outdoor unit, facilitating this process. Because heat pumps move heat rather than generate it, they are exceptionally energy efficient, often resulting in lower energy costs and improved indoor air quality. The reversing valve is essential, enabling the system to switch between cooling and heating modes.

Heat Pump vs. Air Conditioner: What’s Most Efficient?
Modern central air conditioning units are efficient, measured by Seasonal Energy Efficiency Ratio (SEER). High-efficiency air conditioners have a SEER of 14 or above, and most heat pumps meet similar thresholds. This means heat pumps are just as efficient in cooling mode and are significantly more energy-efficient than furnaces or boilers in heating mode. Studies have shown that residential homes can save an average of $948 per year by replacing heating oil systems with cold-climate heat pumps.
Heat Pumps vs. Air Conditioners: Incentive & Rebate Eligibility
Many high-efficiency air conditioners and heat pumps qualify for rebates under the Department of Energy’s ENERGY STAR program. Programs like New York State’s Clean Heat Statewide Heat Pump Program can reduce installation costs significantly. Shenling’s team will help you access applicable energy incentives when designing your heating system.
Heat Pumps vs. Air Conditioners: Indoor Air Quality
Heat pumps, like air conditioners, have air filters to capture dust and hair. Many systems can be upgraded with advanced filtration options, such as antimicrobial filters and UV lights, improving indoor air quality. Since heat pumps do not combust fuel, they significantly enhance air quality compared to fossil fuel-burning systems, which can release pollutants into the air.
Heat Pumps vs. Air Conditioners: Comfort and Tenant Satisfaction
Heat pump systems provide room-by-room temperature control, making them more responsive to comfort needs than central systems, which often result in uneven temperatures. Residents can control their environment, improving tenant satisfaction and retention.
Do Air Conditioners Have Any Advantages?
While air conditioners may initially be less expensive, heat pumps offer dual functionality, effectively replacing both air conditioning and heating systems. This double upgrade can save you money in the long run, especially with energy efficiency rebates and incentives. Shenling also offers Energy Service Agreements (ESAs) to help property owners save without upfront costs.
Heat Pumps vs. Air Conditioners: Operating Lifespan
Air conditioners typically last longer than heat pumps, but this is because heat pumps operate year-round. However, older air conditioning units are less efficient than modern models. Replacing units after about a decade can reduce cooling bills by 20% or more.
Heat Pumps vs. Air Conditioners: Cost Comparison
Initial installation costs, energy efficiency, and potential for heating and cooling are all factors in comparing air conditioners and heat pumps. Although heat pumps may have a higher upfront cost, their energy savings can offset this over time, especially in moderate climates. Ductless mini-split heat pumps can also be less invasive to install than traditional ducted systems.
How Long Does It Take to Switch from A/C to Heat?
Switching from an air conditioning unit to a heat pump system involves several steps, and the timeframe can vary:
- Evaluation and Planning: An HVAC professional assesses your current system, which can take hours to days.
- Selecting the Right Heat Pump: Choosing a model can take a few days to a week.
- Installation Process: Removing the old A/C typically takes about a day, while installing the new heat pump can take 1 to 3 days, depending on system type.
- Ductwork Adjustments: Modifying ductwork can extend the project by several days.
- Testing and Finalization: System testing and inspection can take a few hours to a day.
Overall, the transition can take from a few days to a couple of weeks, depending on project specifics. Discuss the timeline with your HVAC contractor for a clear understanding.
The Best Time to Upgrade to Heat Pumps Is When You Need a New Air Conditioner
Heat pump and air conditioner technologies are nearly identical, but heat pumps offer significant advantages by providing efficient heating. Upgrading makes the most sense when your central A/C unit is nearing the end of its lifespan. Instead of a direct replacement, consider the long-term benefits of a heat pump system.
Shenling can be your partner in designing, installing, and maintaining the ideal solution for your building’s heating and cooling needs. Our experts will recommend tailored solutions while helping you secure available incentives. This streamlined process maximizes savings and reduces stress.
