About This Article

Carrier’s Infinity 20 (24VNA0) Heat Pump with Greenspeed intelligence is the first of its kind. No other ducted, air-source heat pump can beat its heating efficiency.

Are you in the market for a new heat pump? Is your current unit ten years old? Older? Especially if your existing unit is a teenager, you might consider it to be on its last legs. After all, you want to be sure a heat pump can handle the rigors of a new season. A constant parade of HVAC contractors performing maintenance on it to keep it running is not a happy sight. A better investment than repair bills might be a replacement.

At Fire & Ice, we have helped thousands of Columbus homeowners find the HVAC system that best meets their individual needs. When considering heat pumps, we’re often asked if there’s a model that will lower your energy bills, help make you more comfortable, and be affordable. The Carrier Infinity 20 Heat Pump With Greenspeed Intelligence (also known by its model number 25VNA0) fits the bill and might be perfect for you.

This heat pump is the first of its kind. No other ducted, air-source heat pump can beat its heating efficiency. It’s also no slouch when it comes to cooling. But perhaps the biggest thing going for it is what it can do for your home comfort.

In this article, we’ll go over its features, examine the cost, and see who will get the most benefit from this system.

What’s The Difference Between an Air Conditioner and a Heat Pump? https://vimeo.com/438895231

Greenspeed intelligence is created by pairing adaptable-speed technology with Infinity control’s intelligence. The unique, variable-speed compressor of this unit, when managed by the Infinity control as part of a complete Infinity system, allows it to literally adapt its output to the needs of the home.

With tiny adjustments between 40 and 100% capacity, it gives the home only the amount of cooling or heating necessary. This allows the system to operate longer at steadier, lower capacities, which ensures energy efficiency and quiet operation with tighter temperature control than standard systems.

The inverter manages home comfort based on conditions such as indoor temperature, outdoor temperature, humidity levels, thermostat settings, and more. Combined with a variable-speed compressor, the inverter tracks trends and makes intelligent speed and capacity adjustments based on past performance.

As a result, this system can deliver the highest possible comfort with the lowest possible energy use.

What Does Greenspeed Technology Mean for You?

Carrier’s Infinity 20 with Greenspeed intelligence is a lot of heat pump for the money. Its efficiency is about as high as it goes, which means that energy-conscious homeowners can watch their electricity bills go down significantly.

The Greenspeed intelligence is designed to keep the indoor temperature and humidity at exactly where you set it. The variable-speed compressor works harder or less according to both the inside and outside temperature. As the sun heats things up, the unit will work harder or less, depending on the season.

Unlike single-speed compressors, it doesn’t start up at full speed, then shut off as the thermostat is satisfied. It starts up at a much slower speed because you don’t need that much cool/heat yet. As the outside temperature fluctuates, so does the compressor.

It can keep the temperature at a set point no matter how the outside temperature changes.

It also does so quietly. It can be as quiet as 58 decibels, which is about the same as a normal conversation (60 decibels).

And because the Carrier's Infinity 20 runs longer at a slower speed, it’s effective at removing excess humidity from inside your house as well as addressing hot and cold spots. It mixes the air efficiently, providing maximum comfort in every room.

How Heat Pumps’ Efficiency Is Measured

SEER

SEER stands for Seasonal Energy Efficiency Ratio. It’s calculated by the ratio of cooling produced by a heat pump, divided by its energy usage in watt-hours. This ratio is calculated over the length of a typical cooling season.

SEER ratings in modern heat pumps range from about 13 to 22. Depending on the state you live in, any new air conditioner that’s installed must be at least SEER 14. (In some states it’s higher.)

SEER ratings should always be read as “up to” that amount. For example, a 20 SEER system is capable of being up to 20 SEER efficiency. It will not always be at that level, due to variations in your HVAC system.

Many older systems are no higher than about 8 SEER. The savings and comfort difference between those and a 20 SEER system is huge. How large the difference is will depend on your previous air conditioner or heat pump, but the comfort increase and cost savings can be eye-opening.

The Carrier 25VNA0 tips the scale with a SEER of up to 20.5.

EER

The Energy Efficiency Ratio (EER) is the ratio of the average rate of space cooling delivered to the average rate of electrical energy consumed by the air conditioner or heat pump. If you’re in the market for an energy-efficient heat pump, you’ll want to look for models with EER ratings of at least 12. Higher ratings reflect greater efficiency and generally come at a higher cost.

Carrier’s Infinity 20 heat pump is well above that with an EER of up to 16, which is a model of efficiency.

HSPF

HSPF stands for Heating Seasonal Performance Factor. This rating is limited to heat pumps. It’s used to calculate their efficiency when they’re heating a home.

As with SEER and EER, the higher the rating, the more efficient the unit. The numbers used are different, though. Similar to SEER, the rating is calculated by dividing the heating output (measured in British Thermal Units or BTUs) by the energy consumed.

Modern heat pumps must have an HSPF of 7.7, which is an average. As temperatures drop in the winter, the HSFP of a heat pump will decline. The most sophisticated heat pumps can reach 10+ HSPF.

Again, Carrier’s Infinity 20 is way above that line, measuring in at up to 13 HSPF. You would need to buy a ductless mini-split to find an efficiency number that high. No other heat pump can compare.

What Equipment Can I Pair with the Carrier Infinity 20 24VNA0?

The Infinity System Control enables two-way communication between all the major equipment in your heating and cooling system. This ensures that all the components work in unison to maximize energy efficiency and ensure your home is comfortable.

Both the Carrier FE4A and the Carrier FE5A air handlers are part of Carrier’s Infinity series, and both have a variable-speed motor. Each would pair well with this heat pump.

If you prefer a furnace, the 59MN7A Multipurpose Variable-Capacity Condensing gas furnace features the modulating Infinity System, as do its cousins, the Carrier 59TN6 and the Carrier 58TN. Any of these furnaces would allow you to enjoy the Carrier Infinity 20 fully.

If it’s paired with a lesser unit, or with a different brand of HVAC, the heat pump might still work, but it’s unlikely the warranty would cover it and you’ll receive few of the comfort benefits.

Who’s a Good Fit for the Carrier Infinity 20 24VNA0 Heat Pump?

The Carrier Infinity 20 is a good fit for homeowners who plan to stay in their home long-term and are looking for a heat pump that will increase their comfort, be efficient, and is less expensive than higher-end models. If your home has hot or cool areas, or you suffer from excessive humidity in the summer, this will help.

Thanks to its variable-speed compressor, the Infinity 20 can provide even heating and cooling. If energy savings are a concern, it’s been shown that people who have switched to an Infinity 20 from an older 10 SEER or lower heat pump can save an estimated 50% in their annual energy costs.

Who’s Not a Good Fit for the Carrier Infinity 20 Heat Pump?

If you plan on moving out of your home in the next five years, or your current single-stage heat pump already meets your heating and cooling needs, the Infinity 20 might be more system than you need.

And because of the Greenspeed intelligence, you might have to replace your existing furnace or air handler for the systems to talk to one another. One compatible furnace, the Carrier Infinity 98 for instance, costs between $6000 and $7000. That’s a sizable investment.

What Is the Cost of a Carrier Infinity 20 Heat Pump?

Carrier's Infinity 20 with Greenspeed intelligence costs between $8700 - $11,000. At Fire & Ice, our estimates include the cost of equipment, labor, and any additional fees. If your system is all-electric, you will need to replace the air handler as well, which typically adds around $3,500 to $6,000. The factors that can affect the price of your heat pump replacement include:

  • Capacity/power of the system
  • Efficiency
  • The HVAC equipment that you’re not replacing
  • Modifications to your existing system
  • Line set protection
  • Installation costs
  • Tax credits and rebates
