Heat Pump vs Central AC: What Is the Difference?

If you’re trying to decide between a heat pump and central AC, the biggest difference is whether it can heat. While a central AC only cools, a heat pump can heat and cool. 

The right choice for your family will depend on your energy-efficiency goals, climate, comfort requirements, ductwork, existing heating equipment, and budget. To help you decide, we will review each system, its key differences, and its benefits. For a full evaluation, reach out to Rogue Valley Heating, Cooling & Electrical.

The Short Answer: Heat Pumps Heat and Cool, Central AC Only Cools

A central AC is only designed to remove heat from your home and release it outside. A heat pump can work like a central AC in cooling mode. In heating mode, it’s able to reverse direction to bring outdoor heat inside. 

If you have a central AC in Oregon, you’ll need to have a furnace or another heating system to keep you warm in winter. In comparison, a heat pump offers an all-in-one heating and cooling solution.

What Is Central Air Conditioning?

A central AC is a cooling system that uses refrigerant lines, ductwork, an outdoor condenser, an indoor coil, and a blower. It distributes cooled air through the ducts. It works best for homes with existing ductwork. If you already have a reliable furnace or simply want strong summer cooling, it is a good option.

Our team can install a full range of heating, ventilation, and air conditioning (HVAC) equipment. We can evaluate your home’s suitability for central AC systems, heat pumps, ductless mini-splits, and high-efficiency cooling systems.

What Is a Heat Pump?

Meanwhile, a heat pump can transfer heat indoors or outdoors, depending on which mode you set it to. It transfers heat from inside and releases it outdoors in the summer. With the help of the reversing valve, it reverses direction and pulls outdoor heat indoors during the winter. This energy-efficient option is especially popular in Oregon because of its all-in-one system and year-round comfort.

How Are Heat Pumps and Central AC Systems Similar?

These systems are similar because they both:

• Rely on refrigerant to transfer heat
• Connect to ductwork
• Involve an indoor coil and outdoor unit
• Require proper sizing, maintenance, and installation
• Offer high efficiency ratings
• Deliver superior cooling performance when adequately sized

Key Differences Between Heat Pumps and Central AC

While there are many similarities between these systems, there are also key differences that are important to consider.

Heating Capability

While heat pumps can heat and cool, central ACs only cool. If you install a central AC, you’ll need to get a gas furnace, electric heat, or another heating source.

Year-Round Use

Unlike central ACs, heat pumps can be used year-round. As a result, they typically require more frequent maintenance.

Energy Use

When in cooling mode, both systems perform similarly if they have similar efficiency ratings. Heat pumps can be significantly more energy efficient than gas furnaces in heating mode because they move heat instead of burning fuel. Your ultimate energy savings will depend on your heating fuel, electricity rates, home insulation, and HVAC efficiency.

Upfront Cost

Although heat pumps often cost more upfront, central ACs can cost more if you need to install a furnace as well. However, homes that have an existing furnace will likely spend less by opting for a central AC.

Maintenance Needs

A central AC should be serviced each spring before the cooling season begins. Heat pumps should be serviced once before the heating season and once before the cooling season. However, both systems require airflow checks, filter changes, coil cleanings, and refrigerant inspections.

Cooling Performance: Is a Heat Pump as Good as Central AC?

When it is used in cooling mode during our Southern Oregon summers, it works fairly similarly to a central AC. Your overall comfort will depend on the system size, ductwork condition, window exposure, insulation, installation quality, and equipment quality. Ultimately, the real choice is less about the cooling power and more about whether you need energy-efficient heating as well.

Heating Performance: Where Heat Pumps Stand Out

Heat pumps are known for providing efficient heating in mild to moderate climates like Southern Oregon. They offer a practical year-round option, while furnaces are good for supporting homes during colder periods. In our area, some homeowners even opt to use a heat pump and a furnace so that they have gas heat for backup during the coldest days of the year and better energy efficiency during milder weather.

Which System Is More Efficient?

Both cooling systems offer a high level of efficiency. Rather than simply compare cooling systems, you need to look at the SEER2 and EER2 ratings to see which one is more efficient. In terms of heating efficiency, the HSPF2 rating is the best indicator. If an AC and heat pump have similar SEER2 ratings, they can be expected to have similar cooling energy use under comparable conditions.

Some of the largest potential energy savings can come from replacing electric resistance heating or an older, inefficient furnace with a heat pump. However, it’s also important to consider utility costs and your home comfort goals before you make an upgrade decision.

Which System Costs More?

It depends on whether you’re replacing a single system or a full heating and cooling system. For example, opting for a heat pump instead of replacing a central AC and furnace may have a lower upfront cost than replacing both a central AC and furnace separately. If you already have a relatively new furnace and only need a cooling system, a central AC will likely be less expensive. With both systems, Rogue Valley’s financing options can make the total cost more budget-friendly.

Which System Is Better for Southern Oregon Homes?

In Southern Oregon, both systems have important benefits. Heat pumps are often a strong fit for Grants Pass, Medford, and the Rogue Valley because they offer an all-in-one heating and cooling system. However, central ACs are a good choice if you have a newer, reliable furnace.

As you make your decision, you should carefully consider the following factors.

• Your summertime cooling demand
• How old the current furnace is
• If you have existing ductwork
• Your home’s wintertime heating needs
• Your long-term repair and replacement goals
• Energy bills
• Comfort issues, such as uneven temperatures and airflow

When Central AC May Be the Better Choice

A central AC is likely a better choice in the following circumstances.

• You have an existing furnace that’s fairly new.
• You’d like to keep gas heating.
• You only need to get a cooling system.
• Your home’s ductwork is in good condition.
• Your current heating system is reliable and energy efficient.
• You only have space in your budget for getting a cooling system.

When a Heat Pump May Be the Better Choice

There are other instances where a heat pump may be the better option.

• You need an HVAC system that can heat and cool.
• You’re trying to avoid gas or oil heating.
• You need to replace an old, inefficient heating system.
• Your existing furnace and AC are getting older.
• You want a system that provides year-round comfort.
• You live in an area with mild winters, making a heat pump an effective option.
• You may qualify for heat pump-related rebates or incentives.

What About Ductless Heat Pumps?

Not all heat pumps are central ducted systems. Ductless mini-split heat pumps are able to heat and cool specific rooms and zones without the need for ductwork. They are especially effective in home additions, garages, upstairs rooms, offices, sun-facing rooms, and older homes that don’t have any ductwork. If you want to heat and cool a specific space or don’t have existing ductwork, our HVAC technicians can evaluate whether ductless heat pumps are right for you.

Questions To Ask Before Choosing Heat Pump or Central AC

When you reach out for a professional consultation, remember to ask the following questions.

• Is my existing furnace worth keeping?
• What system size will my home need? 
• Is my ductwork in good condition or does it need repairs?
• Will I require any electrical upgrades? 
• What efficiency rating works with my budget?
• Will a dual-fuel system work for my home?
• Are there any rebates or specials available to reduce the overall price?
• What type of financing options are available? 
• How will my system perform during peak heat in the summer and cold winter days?
• What maintenance schedule do you recommend?
